Engineering is the application of scientific and mathematical principles to design, build and improve structures, machines, systems and technologies. It combines technical knowledge with practical problem-solving to develop safe, efficient and innovative solutions.

Engineering influences almost every aspect of modern life, from transportation and energy to manufacturing and industrial automation. By transforming ideas into practical solutions, it enables the development of reliable products, efficient production systems and increasingly advanced technologies.

Etymology

The word engineering derives from engineer, which originated from the Old French engigneor. Its ultimate origin is the Latin word ingenium, meaning “innate ability”, “cleverness”, “inventiveness” or “natural talent”.

The same Latin root also gave rise to English words such as engine, ingenious and ingenuity, all connected with the idea of intelligence, invention and practical problem-solving. Over time, the meaning of engineering evolved from the design of military machines to the broad discipline responsible for creating the technologies, infrastructure and industrial systems that shape the modern world.

The Role of Engineering

Engineering transforms scientific knowledge into practical applications. Engineers design products, optimize manufacturing processes, improve safety, increase efficiency and solve technical challenges across countless industries.

Their work extends beyond designing machines. Engineering also involves analysing problems, selecting suitable materials, evaluating performance, reducing costs and ensuring that products meet functional, environmental and safety requirements.

Engineering Principles

Although engineering covers many different disciplines, every project is based on a common set of principles that guide the development of reliable and efficient solutions.

• Problem solving – identifying technical challenges and developing practical solutions.
• Design – creating products and systems that satisfy functional requirements.
• Analysis – evaluating loads, stresses, performance and reliability.
• Material selection – choosing the most suitable materials for each application.
• Safety – ensuring machines and structures operate safely.
• Efficiency – optimizing performance while reducing energy consumption and maintenance.
• Innovation – improving existing technologies through research and continuous development.

The Engineering Design Process

Most engineering projects follow a structured design process that transforms an initial concept into a finished product.

1. Problem identification.
2. Definition of technical requirements.
3. Concept development.
4. Material selection.
5. Detailed design and simulation.
6. Manufacturing and assembly.
7. Testing, validation and continuous improvement.

This systematic approach helps engineers produce components and systems that are reliable, durable and suitable for demanding operating conditions.

Engineering in Modern Industry

Engineering plays a central role in modern industry, supporting sectors such as manufacturing, construction, mining, agriculture, transportation, aerospace and energy.

Advances in computer-aided design (CAD), CNC machining, robotics, automation and materials science have significantly improved product quality, manufacturing precision and production efficiency.

Mechanical Components in Engineering

Every machine depends on the correct interaction of its mechanical components. Shafts, gears, bearings, bushings, pins, hydraulic cylinders and many other elements work together to transmit forces, reduce friction and ensure reliable operation.

The performance of these components depends not only on their design but also on material selection, heat treatment, manufacturing accuracy and proper maintenance throughout their service life.

Lubrication is the process of applying a lubricant between moving surfaces to reduce friction, wear and heat. It is a fundamental practice in mechanical engineering, used to improve the operation and durability of machines, mechanisms and mechanical components.

Lubrication plays a crucial role in almost every industrial sector, from automotive and construction equipment to manufacturing, mining, agriculture and heavy machinery.

Functions of Lubrication

Although reducing friction is its primary purpose, lubrication performs several other important functions within mechanical systems.

• Reduce friction between moving parts.
• Minimize wear and extend component life.
• Help dissipate heat generated during operation.
• Protect surfaces against corrosion and oxidation.
• Reduce operating noise and vibration.
• Remove contaminants and wear particles from contact surfaces.

Types of Lubrication

Different operating conditions require different lubrication methods. The most common types include:

• Oil lubrication, widely used in engines, gearboxes and hydraulic systems.
• Grease lubrication, suitable for bearings, bushings and components requiring long service intervals.
• Solid lubrication, using materials such as graphite or molybdenum disulfide for extreme temperatures or special applications.
• Dry lubrication, where low-friction coatings reduce wear without conventional lubricants.

Lubrication Regimes

Engineers classify lubrication according to the thickness of the lubricant film separating two moving surfaces.

• Boundary lubrication, where surfaces are only partially separated.
• Mixed lubrication, combining direct contact with a partial lubricant film.
• Hydrodynamic lubrication, where a complete lubricant film separates the surfaces.
• Elastohydrodynamic lubrication, commonly found in rolling bearings and gear contacts under very high loads.

Lubrication in Mechanical Components

Proper lubrication is essential for many mechanical components, including bearings, bushings, gears, shafts, chains and hydraulic equipment. The lubrication method depends on operating speed, load, temperature and environmental conditions.

Selecting the correct lubricant and maintenance interval helps improve efficiency while reducing downtime and maintenance costs.

Lubrication and Steel Bushings

Many steel bushings are designed to operate with grease or oil lubrication to reduce friction between the pin and the bushing during oscillating or rotating movements. Proper lubrication helps minimize wear, dissipate heat and extend the service life of both components, especially in heavy-duty applications such as construction, mining and agricultural machinery.

The term mechanical refers to anything related to machines, mechanisms, moving parts, force and motion. In engineering and industry, it is used to describe systems, components or devices that work through physical movement and mechanical interaction.

A mechanical element can transmit force, support a load, guide movement, reduce friction or connect different parts of a machine. For this reason, the word is often used in expressions such as mechanical parts, mechanical components, mechanical systems and mechanical engineering.

In simple terms, something is mechanical when it depends on physical movement, contact between parts, or the transmission of force rather than purely electrical, digital or chemical processes.

Etymology 

The word mechanical originates from the Latin mechanicus, which derives from the Ancient Greek mēkhanikos (μηχανικός), meaning “relating to devices, contrivances or mechanical arts”. It comes from mēkhanē (μηχανή), a Greek word referring to a device, mechanism or means of accomplishing a task. Over time, the term evolved to describe machines, mechanical systems and the transmission of force and motion in engineering and industry.

Over time, the meaning evolved to describe anything associated with machines, mechanisms and the transmission of force and motion. Today, the term is widely used in engineering, manufacturing and industrial technology to refer to physical systems and components that perform mechanical work.

Mechanical in Engineering

In engineering, the term mechanical describes machines, systems and components designed to generate, transmit or control force and motion. Mechanical engineering combines principles of physics, materials science and mathematics to design reliable and efficient equipment for industrial, commercial and everyday applications.

Today, mechanical engineering plays a key role in industries such as manufacturing, construction, mining, agriculture, transportation and energy, where mechanical systems are essential for converting power into useful work.

Mechanical Systems

A mechanical system is an assembly of interconnected components that work together to perform a specific task through force and motion. Rather than acting independently, mechanical parts interact to transfer energy, guide movement and support operational loads.

Examples of mechanical systems include gearboxes, hydraulic excavator arms, crane booms, conveyor systems, agricultural machinery and industrial production equipment.

Mechanical Properties

Mechanical properties describe how a material behaves when subjected to forces or loads. These characteristics help engineers select the most suitable materials for different applications and operating conditions.

Important mechanical properties include strength, hardness, toughness, stiffness, wear resistance, fatigue resistance and ductility. Selecting the appropriate material is essential for ensuring safety, reliability and long service life.

Industrial Applications of Mechanical Engineering

Mechanical engineering supports virtually every industrial sector by providing machines, equipment and mechanical systems capable of performing complex tasks efficiently and reliably.

Mechanical technologies are widely used in construction equipment, mining machinery, agricultural equipment, lifting systems, manufacturing plants, railway applications, marine engineering and many other industries where durability, precision and high load capacity are required.

Mechanical Parts and Components

Mechanical parts are the individual elements that make up a machine or mechanical system. Each component performs a specific function, such as supporting loads, transmitting motion, reducing friction or connecting moving assemblies.

Common examples of mechanical components include gears, shafts, bearings, bushings, pins, springs, couplings, hydraulic cylinder parts and fasteners. The performance and durability of a machine largely depend on the quality and correct design of these components.

Demolition equipment includes the machines and attachments used to dismantle buildings, bridges, industrial plants, roads and other structures.

Modern demolition is not only about breaking down a structure. In many projects, operators must work in a controlled way, separate different materials, reduce dust and noise, and recover concrete, steel, asphalt and other materials for recycling.

For this reason, demolition sites use a combination of complete machines and interchangeable attachments. Machines provide movement, reach, power and stability. Attachments perform specific tasks such as breaking, cutting, crushing, sorting and loading.

Types of Demolition Attachments

Hydraulic Breaker

Hydraulic breakers are impact tools used to break concrete, asphalt, rock, foundations and other hard materials. They are among the most widely used excavator attachments in demolition and construction.

Epiroc describes hydraulic breakers as impact devices used for demolition, rock excavation, trenching, foundation work and asphalt cutting. The company also notes that hydraulic breakers are among the oldest hydraulic attachments for carriers. :contentReference[oaicite:0]{index=0}

Demolition Shear

Demolition shears are designed to cut steel structures, beams, pipes, tanks and reinforced metal components.

They are widely used in industrial demolition, scrap processing and structural dismantling, especially where metal elements must be cut into smaller sections before removal.

Orange Peel Grapple

An orange peel grapple is a multi-tine attachment used to grab loose materials such as scrap metal, debris and mixed demolition waste.

The name comes from the shape of its curved tines, which resemble the segments of an opened orange peel. It is often used with material handlers and excavators in recycling yards and demolition sites.

Sorting Grapple

A sorting grapple is used to select, separate and move materials after demolition. It can handle concrete pieces, wood, metal, bricks and mixed debris.

Compared with an orange peel grapple, a sorting grapple usually has two larger jaws and a more controlled grip, making it useful when materials must be separated with precision.

Demolition and Recycling

Recycling is now a central part of many demolition projects. Concrete can be crushed and reused as aggregate, steel can be separated and sent to scrap recovery, and other materials can be sorted before disposal or reuse.

This is why demolition equipment is often connected with recycling equipment. Excavators, material handlers, grapples, mobile crushers and screening systems work together to reduce waste and recover useful materials.

Demolition Equipment Manufacturers

The demolition equipment industry includes both manufacturers of complete machines and companies specialized in attachments for excavators and material handlers.

Among the most widely used machine manufacturers are Caterpillar, Komatsu, Hitachi, Liebherr, Volvo  and Kobelco. Their excavators and material handlers are commonly found on demolition sites around the world, from small urban projects to large industrial dismantling operations.

In the attachment sector, several companies focus specifically on demolition and recycling tools.

Epiroc is one of the best-known manufacturers of hydraulic breakers and demolition attachments. Its portfolio includes breakers, grapples, pulverizers, crusher buckets and other tools used in construction, demolition and recycling.

Indeco, based in Italy, is recognized for its hydraulic hammers and a range of demolition attachments including pulverizers, shears and grabs. Its products are used in construction, quarrying and demolition projects worldwide.

VTN Europe is another Italian manufacturer specialized in demolition and recycling equipment. The company produces demolition shears, concrete crushers, pulverizers, sorting grapples and other attachments designed for heavy-duty applications.

Other established manufacturers in the sector include Mantovanibenne, Trevi Benne, LaBounty, Genesis Attachments, NPK and Okada Aiyon. These companies offer specialized solutions for structural demolition, scrap processing, material recovery and recycling operations.

Today, demolition contractors often combine machines from one manufacturer with attachments from another, selecting the most suitable equipment according to the type of structure, material and project requirements.

On 1 July 2026, the new European safeguard system for steel imports entered into force. With the new regulation, the European Union strengthened the measures already introduced in 2018, reducing duty-free import quotas and increasing the duty applied to volumes exceeding the available quotas.

The aim is to protect the European steel industry from the effects of persistent global overcapacity and the growing inflow of steel from third countries.

What changes from 1 July 2026

The new system maintains the mechanism of tariff-rate quotas (TRQs), but introduces significant changes compared with the previous regime.

The main changes are:

• reduction of annual duty-free import quotas;
• total quota set at 18,345,922 tonnes;
• increase of the out-of-quota duty from 25% to 50%;
• new system for distributing quotas between countries with preferential trade agreements and other exporting countries.

Imports falling within the available quotas can continue to enter the European market without paying the safeguard duty. Once the quota for a specific product category is exhausted, imports are subject to a 50% ad valorem duty, in addition to any other applicable customs duties.

Product categories covered

The new safeguard measures apply to 26 categories of steel products. The following categories are listed in Annex I of Regulation (EU) 2026/1384:

• Non Alloy and Other Alloy Hot Rolled Sheets and Strips
• Non Alloy and Other Alloy Cold Rolled Sheets
• Electrical Sheets (other than GOES)
• Metallic Coated Sheets
• Organic Coated Sheets
• Tin Mill Products
• Non Alloy and Other Alloy Quarto Plates
• Stainless Hot Rolled Sheets and Strips
• Stainless Cold Rolled Sheets and Strips
• Stainless Hot Rolled Quarto Plates
• Non Alloy and Other Alloy Merchant Bars and Light Sections
• Rebars
• Stainless Bars and Light Sections
• Stainless Wire Rod
• Non Alloy and Other Alloy Wire Rod
• Angles, Shapes and Sections of Iron or Non Alloy Steel
• Sheet Piling
• Railway Material
• Gas Pipes
• Hollow Sections
• Seamless Stainless Tubes and Pipes
• Other Seamless Tubes
• Large Welded Tubes
• Other Welded Pipes
• Non-alloy and other alloy cold finished bars
• Non Alloy Wire

Why the quota was set at 18.3 million tonnes

The European Commission calculated this volume by applying the import market share recorded in 2013, around 13%, to total steel consumption in the European Union in 2024, the latest year for which complete data were available.

Imports originating in Russia and Belarus, which are already subject to import bans in the European Union, were not included in the calculation. The result is a total annual quota of 18,345,922 tonnes.

Why the EU strengthened the measures

According to the European Commission, the global market continues to be affected by significant production overcapacity.

Estimates indicate that excess capacity could increase from 602 million tonnes in 2024 to 721 million tonnes by 2027, creating growing pressure on imports into the European market.

Since 2018, the European steel sector has also recorded:

• more than 30 million tonnes of lost production capacity;
• around 30,000 jobs lost;
• an average capacity utilisation rate of only 67% in 2024.

The previous system introduced in 2018

Safeguard measures had already been introduced in 2018, following tensions in international steel trade.

The system provided for:

• tariff-rate quotas (TRQs);
• imports within quota without additional duty;
• a 25% duty on imports exceeding the available quota.

The new regulation keeps this structure, but reduces the available volumes and doubles the out-of-quota duty.

How the new quotas are distributed

The quotas are not distributed exclusively on the basis of historical import or export volumes.

Article 5 of the regulation states that the European Commission must take several elements into account, including:

• the historical import market share;
• the distribution of imports by product category;
• existing or future trade agreements;
• the effects of trade measures adopted by third countries;
• diversification of sources of supply;
• other elements of interest to the European Union.

The implementing regulation also provides for a distribution of quotas between trading partners with preferential agreements and other exporting countries, as well as country-specific quotas for certain countries and product categories.

Are countries with trade agreements subject to the new duty?

Yes.

Countries benefiting from preferential trade agreements with the European Union are also subject to the new system. Once the available quotas are exhausted, the 50% duty also applies to them.

Only Iceland, Liechtenstein and Norway are excluded, along with cases where specific bilateral safeguard measures provided for by the regulation apply.

Which sectors could be most affected

The new measures concern steel products and semi-finished products used in many industrial sectors.

The sectors that could be most affected include:

• construction;
• automotive;
• earthmoving machinery;
• agricultural machinery;
• industrial plants;
• mechanical components;
• oil & gas;
• railway infrastructure.

The actual impact will mainly depend on the imported product category, the country of origin and the speed at which available quotas are exhausted during the year. If the quota for a specific category is reached quickly, importing companies will have to pay the new 50% duty, with possible increases in procurement costs for certain raw materials and semi-finished products.

Sibo Steel Bushings

For companies using steel components and semi-finished steel products, monitoring the evolution of import quotas and their potential impact on raw material procurement costs will become increasingly important.

SIBO is a word with several different meanings. In most online searches, it refers to the medical acronym Small Intestinal Bacterial Overgrowth. However, the same term can also refer to companies, places, people, computing history and other acronyms.

This page is a short disambiguation guide: its purpose is to clarify the main meanings of SIBO and help readers understand which one is relevant in each context.

SIBO in Medicine

In medicine, SIBO stands for Small Intestinal Bacterial Overgrowth. It refers to an abnormal increase in bacteria in the small intestine, especially bacteria that are not usually found there in high quantities.

This is the most common meaning of the acronym online. Medical websites, articles and patient guides often use SIBO to describe a digestive disorder linked to symptoms such as bloating, abdominal discomfort, gas, diarrhoea, constipation or malabsorption.

This medical meaning is unrelated to companies, places or industrial products that use the name Sibo. The overlap is purely linguistic: the same letters are used in different contexts.

SIBO as a Company Name

Sibo is also used as a company name by different businesses in different sectors and countries. In this case, the word does not usually function as a medical acronym, but as a brand, company name or commercial identity.

Examples include:

• Sibo Srl – Italy
• SIBO Group – Slovenia
• SIBO Business – South Africa
• SIBO S.p.A. – Italy

Sibo Srl is an Italian manufacturer of steel bushings and precision mechanical components for heavy-duty applications. The company works mainly with sectors such as construction machinery, agricultural machinery, mining equipment, lifting systems and industrial applications.

SIBO Group is another company using the same name, active in a different industrial field. SIBO Business operates in South Africa in business technology and consulting services. SIBO S.p.A., based in Italy, is connected with automation and machinery for wood and metalworking processes.

These examples show why the word SIBO should always be interpreted according to the context. A search for “Sibo company” may refer to very different businesses.

Sibo as a Place Name

Sibo is also a place name in Sweden. Sibo, Sweden is a locality in Bollnäs Municipality, in Gävleborg County.

This geographical meaning is separate from the medical acronym and from company names. It is another example of how the same word can appear in different contexts without having the same origin or meaning.

SIBO in Computing

In computing history, SIBO is associated with the Psion Organiser family of pocket computers. It is commonly linked to Psion’s 16-bit organiser platform and software environment.

This meaning belongs to the history of handheld computers and personal digital assistants, especially before smartphones became common. It is a niche meaning today, but still relevant in discussions about early portable computing devices.

People Named Sibo

Sibo can also appear as a personal name or surname.

• Kwasi Sibo – Ghanaian professional footballer.
• Sibo – Chinese poet of the Qing dynasty.

In these cases, Sibo is not an acronym. It is part of a person’s name, which again makes the context essential for understanding the correct meaning.

SIBO as an Acronym

Besides the medical meaning, SIBO may also be used as an acronym by organizations, associations, projects or local initiatives. These uses are usually less common and depend heavily on the specific field or country.

For this reason, when the term appears without context, it is useful to check the surrounding words: medicine, company names, geography, computing or people usually make the intended meaning clear.

Why Is Our Company Called SIBO?

The name SIBO comes from the Italian words Società Italiana Boccole, which literally mean Italian Bushings Company. Since the company was founded, steel bushings have been our core specialization and remain the main focus of our production today.

If you would like to learn more about our steel bushings, you can browse our catalogue or contact us for technical information and custom manufacturing solutions.

Cranes are among the most important lifting machines used in construction, industry, logistics, ports, mining, energy and marine operations. Although their designs can vary greatly, all cranes have the same basic purpose: lifting, moving and positioning loads that would be impossible or unsafe to handle manually.

This article provides a general overview of the main types of cranes, how they work, where they are used and which mechanical components are most exposed to wear during operation.

A crane is a lifting machine designed to raise, lower and move heavy loads. It usually combines a structural frame, a lifting mechanism, a hook or lifting device, and a system that allows the load to be moved vertically, horizontally or rotationally.

Cranes are used when heavy materials, machinery or structures need to be positioned with precision. Depending on the application, a crane may be fixed to the ground, mounted on a vehicle, installed inside a factory, placed on rails, supported by tracks or even mounted on a floating platform.

Etymology

The word crane ultimately derives from the Old English cran, which referred to the long-necked bird. The term can be traced back to Proto-Germanic roots and has related forms in several European languages. By the late Middle Ages, the name was also being used for lifting machines, likely because their shape was thought to resemble the neck and head of a crane.

Types of Cranes

There is no single universal system for classifying cranes. Some categories are based on mobility, others on structure, installation method or operating environment. As a result, some crane types can overlap. For example, a telescopic crane may also be a mobile crane, while a maritime crane can be installed on a ship, offshore platform or pedestal structure.

Tower Cranes

Tower cranes are among the most recognizable lifting machines and are a common sight on construction sites around the world, from residential developments to skyscrapers and major infrastructure projects.

Their structure typically includes a vertical mast, a rotating slewing unit, a horizontal jib and a counter-jib with counterweights. Tower cranes are mainly used for lifting construction materials such as steel beams, concrete elements and prefabricated components at significant heights.

Mobile Cranes

Mobile cranes are lifting machines mounted on wheeled carriers. Their main advantage is mobility, allowing them to travel between job sites and be positioned quickly where lifting work is required.

They are widely used in construction, infrastructure, industrial maintenance and transport operations. Many models use telescopic booms and outriggers to adapt to different working conditions.

All-Terrain Cranes

All-terrain cranes are designed for both road travel and construction site operations. They combine good road mobility with the ability to work on more challenging terrain.

They are commonly used in infrastructure projects, industrial installations, wind energy and heavy lifting applications where flexibility is important.

Rough Terrain Cranes

Rough terrain cranes are built specifically for off-road environments. Large tires and robust chassis designs allow them to operate on uneven or unpaved surfaces.

They are often used on construction sites, industrial yards, energy projects and remote work areas where maneuverability and stability are critical.

Telescopic Cranes

Telescopic cranes use booms made of multiple sections that extend and retract hydraulically. This allows the crane to adjust its reach according to lifting height and working distance.

Telescopic booms are commonly found on mobile cranes, truck-mounted cranes and other compact lifting machines.

Crawler Cranes

Crawler cranes are mounted on tracks rather than wheels. This configuration improves stability and distributes weight more evenly on soft or uneven ground.

They are commonly used in large construction projects, bridge construction, industrial plants, wind farms and other heavy lifting applications.

Overhead Cranes

Overhead cranes, also known as bridge cranes, are typically installed inside factories, warehouses and manufacturing facilities. They move along elevated runways and transport heavy materials across the work area.

They are widely used in production plants, workshops and heavy industry where frequent material handling is required.

Gantry Cranes

Gantry cranes perform a similar function to overhead cranes but are supported by their own legs rather than by a building structure.

They are commonly used in ports, shipyards, logistics terminals and outdoor industrial areas where a fixed overhead system is not available.

Loader Cranes

Loader cranes are hydraulic cranes mounted on trucks. They are designed to load and unload materials directly from the vehicle carrying them.

Their compact articulated design makes them useful for deliveries, construction work, maintenance operations and municipal services.

Floating Cranes

Floating cranes are installed on barges or other floating platforms. They are used for heavy lifting operations on water, including bridge construction, salvage work and marine infrastructure projects.

Their floating configuration allows them to reach locations that are inaccessible to land-based cranes.

Maritime Cranes

Maritime cranes are designed for marine and offshore environments, where corrosion, wind and vessel movement create demanding operating conditions.

This category includes ship cranes, offshore cranes, pedestal cranes and knuckle boom cranes used for cargo handling, maintenance work and offshore lifting operations.

Because maritime cranes represent a specialized sector of the lifting industry, we have covered them in a dedicated article.

How Cranes Work

Although crane designs differ, the basic principle is always the same: a crane lifts a load and moves it in a controlled way. This movement may be vertical, horizontal, rotational or a combination of these actions.

The lifting force is usually generated by a hoisting system, which may use wire ropes, chains, hydraulic cylinders or other mechanical systems depending on the crane type. The load is connected to a hook, lifting beam or other attachment device.

Stability is one of the most important aspects of crane operation. Cranes use counterweights, outriggers, tracks, fixed foundations or structural supports to balance the load and prevent tipping. The relationship between load weight, lifting radius and crane configuration is critical for safe operation.

Main crane components can include the boom, jib, mast, hook, hoist, counterweight, slewing system, undercarriage and support structure. The exact configuration depends on the crane category and working environment.

Industrial Applications of Cranes

Cranes are used across many industrial sectors where heavy materials, equipment or structures need to be lifted and positioned safely.

Construction and Infrastructure

In construction, cranes are used to lift steel structures, concrete elements, formwork, machinery and building materials. Tower cranes, mobile cranes and crawler cranes are especially common in residential, commercial and infrastructure projects.

Manufacturing and Heavy Industry

Factories, steel plants, workshops and industrial facilities rely heavily on overhead cranes, gantry cranes and jib cranes to move heavy components through production and maintenance areas.

Logistics and Warehousing

In logistics, cranes support the movement of containers, pallets, machinery and heavy goods. Gantry cranes and overhead cranes are often used in terminals, warehouses and intermodal facilities.

Mining and Quarrying

Cranes play an important role in mining and quarrying operations, particularly during equipment assembly, plant construction and maintenance activities. They are commonly used to handle large components, perform repairs and support heavy lifting operations in mines, quarries and processing facilities.

Ports, Marine and Offshore Operations

Ports, shipyards and offshore installations use cranes for cargo handling, vessel maintenance, marine construction and offshore lifting. In these environments, crane design must consider corrosion, wind, dynamic loads and limited working space.

Energy and Utilities

Cranes are widely used in energy projects, including power plants, wind farms, oil and gas facilities and utility infrastructure. They are required for installing turbines, lifting plant components and supporting maintenance operations.

A Brief History of Cranes

The first cranes appeared in Ancient Greece, where they were used to lift heavy stone blocks during construction. The technology was later adopted and developed further by the Romans, who used lifting machines in large building projects, infrastructure works and port operations.

During the Middle Ages, cranes became important in the construction of cathedrals, fortifications and harbor facilities. Many early cranes were powered manually by workers or by animals using treadwheels, winches and simple mechanical systems.

The Industrial Revolution transformed crane technology. Steam power, steel structures, electric motors and hydraulic systems made cranes stronger, more precise and suitable for increasingly demanding industrial applications.

Today, cranes range from compact loader cranes to giant crawler cranes, offshore lifting systems and automated industrial cranes used in highly specialized environments.

Main Crane Manufacturers

The crane industry includes several international manufacturers serving different segments of the market. Some companies focus mainly on construction cranes and mobile cranes, while others specialize in industrial lifting, port equipment, offshore cranes or truck-mounted lifting systems.

Among the best-known manufacturers are Liebherr, Tadano, Manitowoc, Terex, Magni, Konecranes, Palfinger,Fassi. Their product ranges cover tower cranes, mobile cranes, crawler cranes, overhead cranes, gantry cranes, loader cranes and specialized lifting systems for industrial and infrastructure applications.

Mechanical Components Subject to Wear

Cranes operate under repeated loads, movement, vibration and environmental stress. For this reason, several mechanical components are subject to wear and require careful material selection, lubrication and maintenance.

Pins and Bushings

Pins and bushings are commonly used in articulation points, boom connections, hydraulic cylinder mounts and other moving joints. These components help manage rotation, oscillation and load transfer between connected parts.

Sibo Steel Bushings Catalog

Sibo manufactures steel bushings for cranes and other heavy-duty applications where high loads, continuous articulation and severe operating conditions require reliable wear-resistant components.

For demanding environments, we produce bushings with advanced thermochemical surface hardening treatments that provide excellent wear resistance, high surface hardness and improved corrosion, erosion and adhesion resistance, while maintaining excellent sliding performance.

For corrosive applications, including marine and saline environments, we also manufacture stainless steel bushings using materials such as AISI 316, AISI 420 and AISI 440C.

Maritime cranes are lifting machines designed to operate in marine and offshore environments, where saltwater, wind, corrosion and continuous movement create more demanding conditions than those typically found on land.

They are commonly used on ships, offshore platforms, service vessels and marine installations for cargo handling, maintenance work and offshore operations.

Unlike traditional land-based cranes, maritime cranes often work in limited spaces while dealing with vessel motion, dynamic loads and harsh environmental conditions.

Main Types of Maritime Cranes

Here are some of the most common categories:

Offshore cranes: Used on offshore platforms, offshore vessels and marine energy installations, designed for demanding offshore environments.

Ship cranes: Installed directly on ships and marine vessels for cargo handling, onboard logistics and maintenance operations.

Pedestal cranes: Cranes mounted on a vertical column structure, widely used in offshore and marine applications because of their robustness and compact footprint.

Knuckle boom cranes: Articulated cranes designed for compact movement and precise load positioning, especially useful in confined marine working areas.

There is no single universal classification for maritime cranes. In practice, manufacturers and operators commonly group these cranes according to operating environment, installation method and structural configuration.

For this reason, these categories are not always mutually exclusive. A crane may belong to more than one category at the same time depending on its structure, installation or application. For example, a lattice boom crane may also use a pedestal configuration, while a knuckle boom crane can be installed on ships, offshore vessels or marine platforms.

Offshore and Marine Applications

Maritime cranes are used in a wide range of marine and offshore sectors.

In the offshore industry, they are commonly found on oil and gas platforms, offshore wind installations and offshore construction vessels, where they are used for lifting heavy equipment, supporting maintenance operations and handling materials in difficult environmental conditions.

Ship cranes and deck cranes are widely used for cargo handling, onboard logistics and support operations on commercial and service vessels.

Knuckle boom cranes are often preferred for maintenance and service work because their articulated structure allows more compact movement and improved load control in restricted areas.

Large offshore cranes can also be used for heavy lifting operations involving offshore modules, subsea equipment and marine construction projects.

Specialized Offshore Crane Designs

In addition to the most common maritime crane categories, manufacturers also produce specialized offshore crane solutions for specific applications.

Some examples include:

• Lattice boom cranes
• Stiff boom cranes
• Leg encircling cranes
• Offshore mast cranes

These crane designs are generally used in heavy offshore lifting, offshore construction projects, jack-up vessels and large marine installations where high lifting capacity or optimized deck space are required.

Main Maritime Crane Manufacturers

Several international companies are considered important references in the maritime and offshore crane sector. Among the best-known are Liebherr (offshore, ship and deck cranes), MacGregor (marine cargo handling and shipboard equipment), Palfinger Marine (marine and offshore lifting solutions), Huisman (heavy offshore lifting systems), Konecranes (industrial and port lifting equipment), Heila (marine cranes) and Melcal (marine and offshore cranes).

These manufacturers serve different segments of the maritime crane market, from offshore platforms and construction vessels to cargo ships, ports and specialized marine applications.

Mechanical Components and Wear in Maritime Cranes

Components such as bushings, pins, slewing systems and articulated joints are therefore subject to continuous wear and heavy mechanical stress, especially in offshore environments exposed to saltwater and humidity.

For marine and offshore applications, the choice of materials, surface treatments and lubrication systems plays an important role in the long-term reliability of the crane.
