Sandvik is a Swedish multinational engineering group primarily operating in the mining, infrastructure, and metal-working sectors. With a commercial presence in approximately 150 countries, the company is structured to provide solutions ranging from giant underground excavation machinery to high-precision machining tools.This industrial configuration is the result of a journey that began in 1862, characterized by a transition from basic steelmaking to the development of advanced technologies for rock breaking and processing.

Origins: Sandviken and Bessemer Steel

The company’s activity officially began in 1862 in Sandviken (meaning “the sandy bay”), founded by Göran Fredrik Göransson. The location was strategically chosen for its proximity to Swedish iron mines, as well as its access to the railway network and the water resources essential for production.

The determining factor for the company’s early growth was the industrial-scale application of the Bessemer method. Sandvik succeeded in stabilizing this process, obtaining steel with consistent purity and strength. The product catalog at the time focused on heavy-duty applications: pipes, blades, and hollow drill steels for rock drilling, laying the foundation for what would become the group’s core business.

1942: The Development of Carbides (Coromant)

In 1942, the company established the Sandvik Coromant brand, a name derived from the combination of Coromandel (a raw material sourcing area) and Diamant (diamond). The brand was created to identify the production of cemented carbide (hard metal).

The integration of carbides addressed the technical need to exceed the physical limits of traditional steel in excavation and cutting operations. Compared to steel bits, cemented carbide guaranteed longer operational life and the ability to maintain performance at high temperatures—a critical factor for efficiency in mining sites and workshops.

 

Rock Engineering: Drilling and Excavation Systems

Today, the Mining and Rock Solutions division serves as a primary pillar of the Group. Sandvik is globally recognized for the design and production of complex machinery destined for the most demanding extraction environments:

  • Drill Rigs and Rock Drills: Self-propelled units for underground and surface drilling, engineered to operate on high-hardness rock.
  • Load and Haul Equipment (LHD): Pale and dumper articolati ottimizzati per la movimentazione in gallerie e spazi ristretti.
  • Automation Systems: Digital platforms that allow for the remote and autonomous management of machinery, reducing human presence in high-risk areas.

The operational structure is completed by the Rock Processing Solutions division, dedicated to crushing and screening plants, and the Manufacturing and Machining Solutions division, which focuses on precision tools for metal cutting.

Current technological initiatives are focused on fleet electrification, aiming to eliminate emissions in underground environments, and optimizing production cycles through digital data analysis.

The History of Komatsu

Komatsu-G40-first-Japanese-bulldozer

Today, Komatsu is the world’s second-largest manufacturer of construction equipment, but its origin wasn’t a commercial strategy—it was a matter of survival. In 1921, the company was merely the internal mechanical workshop for the Yusenji copper mine in Ishikawa Prefecture.

When the mine’s copper veins began to run dry, owner Meitaro Takeuchi decided not to close down. Instead, he transformed his maintenance crew into machinery builders. The workshop was separated from the parent mining company to become an independent entity.

The name Komatsu (literally “Little Pine” in Japanese) was chosen to honor the local city. Takeuchi preferred this territorial identity over his own family name, applying the expertise gained from repairing underground tools to the construction of surface machinery.

Technical Milestones:

  • 1921: Official Founding. Meitaro Takeuchi separates the workshop from the mine. Komatsu Ltd. is born.

  • 1924: Hydraulic Press. Completion of the first hydraulic press for metal forming, marking the shift to industrial manufacturing.

  • 1931: Agricultural Tractor. Production of the first Japanese crawler tractor prototype for farm mechanization.

  • 1943: First Bulldozer (G40). Design of Japan’s first domestic bulldozer. Originally built for wartime use, it became the technical blueprint for the entire civilian line.

  • 1961: Cummins Agreement. Technical partnership with the American firm Cummins to produce high-performance diesel engines globally.

  • 2008: Hybrid Technology. Launch of the PC200-8, the world’s first hybrid hydraulic excavator with energy recovery during swing rotation.

This evolution allowed Komatsu to maintain full control over its supply chain, still producing its own steel and complex mechanical components—a direct legacy of its metallurgical roots.

      Amphibious Machinery

      Types of Amphibious Machinery

      Operating in wetlands, marshes, and deltas requires specialized machinery known as swamp equipment. These machines are engineered to work on terrain with extremely low soil-bearing capacity where standard equipment would immediately sink. In the industry, these are often referred to as Marsh Buggies when focusing on mobility and transport, or Amphibious Excavators when configured for heavy digging, both utilizing buoyancy to conquer mud and shallow water.

      The Technology: Pontoons and Buoyancy

      The core feature of swamp machinery is the amphibious undercarriage. Instead of standard wheels or narrow steel tracks, these machines are equipped with large, hollow, airtight steel pontoons. This design allows the machine to distribute its massive weight over a large surface area, resulting in ground pressure that is often lower than that of a human footprint.

      Main Types of Swamp Machinery

      The versatility of the amphibious base allows for several specialized configurations, designed for specific tasks in the most difficult environments:

      • Amphibious Excavators: Standard excavator units mounted on pontoons, used for dredging, canal cleaning, and flood control.
      • Marsh Buggy Carriers: Platforms designed for mobility, moving personnel, fuel, and supplies across difficult terrains.
      • Amphibious Dredgers: Specialized units equipped with suction pumps or cutter heads for sediment removal in shallow waters.
      • Amphibious Cranes: Heavy-duty telescopic cranes mounted on amphibious undercarriages, essential for infrastructure maintenance and pipeline installation in swampy areas.
      Types of Amphibious Machinery
      The main types of amphibious machinery used for dredging, transport, and infrastructure maintenance in marshy environments.

      Main Manufacturers of Swamp Equipment

      The global market for amphibious machinery is led by a few specialized manufacturers that define the standards for reliability and performance in extreme environments. Understanding the different players helps in identifying the right technology for specific wetland projects.

      • JVS Techniek (Netherlands): Specialists in the engineering and production of custom-built amphibious undercarriages and pontoons, known for their high-quality technical solutions for dredging and water management.
      • Watermaster (Finland): Famous for the “Classic” multipurpose dredger. These machines are self-propelled and can “walk” into the water using their own boom and stabilizers, specializing in suction dredging and piling.
      • Wilco Manufacturing (USA): A pioneer in the Marsh Buggy industry. Based in Louisiana, they specialize in heavy-duty amphibious undercarriages for pipeline construction and large-scale wetland excavation.
      • Remu (Finland): Renowned for the “Big Float” series. Their engineering focus is on hydraulic extendable pontoons, allowing large excavators to be transported easily on standard roads while maintaining high stability in deep mud.
      • Marshland Equipment (USA): Specialists in high-capacity cargo buggies and specialized platforms for geological surveys and infrastructure maintenance in inaccessible swampy areas.

      Mechanical Durability in Extreme Environments

      Working in wetlands presents a unique mechanical challenge: the constant presence of abrasive slurry. This mixture of water, sand, and organic debris acts as a grinding agent on every moving joint, potentially leading to rapid wear and costly downtime for the fleet.

      To ensure a long service life, these machines rely on high-quality steel bushings. These components are critical for proper load distribution and resistance against the friction generated during dredging or excavation. Specialized heat treatments and precision-engineered internal grooves are essential to keep lubricants in and contaminants out, even when the undercarriage is fully submerged.

      Whether you are operating an Amphibious Crane or a fleet of Marsh Buggies, choosing the right wear parts is the most effective way to protect your investment in these extreme environments.

          Dump Trucks

          Comparison chart showing four dump truck types: on-road dump truck, articulated dump truck, underground dump truck, and rigid mining dump truck.

          A dump truck is a heavy vehicle designed to transport and unload loose materials such as soil, aggregates, overburden, and blasted rock. The term dumper is sometimes used interchangeably, particularly in British English or for compact site machines. However, in industrial and mining contexts, “dump truck” is generally the more common technical designation.

          In construction and mining industries, dump trucks can be classified into four main categories based on structural design and operating environment: rigid, articulated, underground, and on-road.

          1. Rigid Dump Trucks

          Rigid dump trucks are large off-highway machines built on a single, non-articulated frame. The cab and dump body are mounted on a rigid chassis, with no central pivot joint.

          Main characteristics:

          • Extremely high payload capacity

          • Designed for open-pit mining and large quarries

          • Heavy-duty rear tipping body

          • Massive off-road tires

          • Reinforced frame for continuous high-load cycles

          Rigid dump trucks are typically used in large-scale mining operations where production efficiency is critical. They operate in controlled haul roads and are not designed for public road circulation.

          These machines can exceed 300 tonnes of payload in ultra-class configurations.

          2. Articulated Dump Trucks (ADT)

          Articulated dump trucks feature a pivot joint between the tractor unit and the rear dump body. This articulation improves maneuverability and traction, particularly on uneven or soft terrain.

          Main characteristics:

          • Central articulation joint

          • All-wheel drive in most configurations

          • Better stability on slopes and rough terrain

          • Medium to high payload capacity

          Articulated dump trucks are widely used in large construction sites, infrastructure projects, earthmoving operations, and medium-scale mining.

          The articulation joint is a key mechanical element, allowing improved turning radius and operational flexibility.

          3. Underground Dump Trucks

          Underground dump trucks are specifically engineered for mining operations below ground. Their design differs significantly from surface haul trucks.

          Main characteristics:

          • Low-profile structure

          • Compact dimensions

          • Reinforced cabin and protective systems

          • Heavy-duty driveline and braking systems

          These machines operate in confined tunnels with limited ceiling height and restricted ventilation. They must balance durability with compact geometry.

          4. On-Road Dump Trucks

          On-road dump trucks are based on commercial truck chassis and are homologated for public road use. Unlike rigid or articulated mining trucks, they must comply with traffic regulations and weight limitations.

          Main characteristics:

          • Road-legal configuration

          • Steel dump body mounted on highway truck frame

          • Used in urban construction and infrastructure

          • Lower payload compared to off-highway models

          These trucks are commonly used to transport materials between construction sites, asphalt plants, and infrastructure projects.

          Site Dumpers (Compact Construction Dumpers)

          In addition to large mining and construction dump trucks, the term dumper is commonly used to describe compact site machines designed for small to medium construction projects.

          Site dumpers are typically:

          • Compact and highly maneuverable

          • Articulated in many configurations

          • Designed for short-distance material transport

          • Used in urban works, landscaping, and residential construction

          Unlike rigid or articulated mining dump trucks, site dumpers have significantly lower payload capacities and are not intended for large-scale earthmoving or mining operations. Their strength lies in versatility, accessibility, and ease of operation in confined job sites.

          Manufacturers such as Wacker Neuson SE and Thwaites Ltd are well known in this segment, particularly in European markets.

          Although mechanically simpler than heavy mining haul trucks, site dumpers still rely on robust pivot systems and wear-resistant components in their tipping and articulation mechanisms.

          Compact Site Dumper for Construction Applications

          Leading Manufacturers in the Dump Truck Sector

          The dump truck market is dominated by a number of global manufacturers, each with strong specialization depending on application and industry segment.

          In large-scale surface mining, companies such as Caterpillar Inc. and Komatsu Ltd. are among the leading producers of rigid haul trucks, offering ultra-class machines designed for high-capacity open-pit operations.

          In the articulated dump truck segment, manufacturers like Volvo Construction Equipment and Bell Equipment are well established in construction and earthmoving markets.

          For underground mining applications, companies such as Sandvik AB specialize in low-profile, heavy-duty trucks engineered specifically for confined mining environments.

          These manufacturers define the technical standards of the industry in terms of payload capacity, structural strength, drivetrain design, and durability.

            The History of the Agricultural Tractor

            Evolution of the tractor from 1902 to today

            The tractor is one of the most transformative machines in agricultural history. It replaced animal power, reduced manual labor, increased productivity, and reshaped rural economies. Its evolution mirrors the broader development of mechanical engineering and industrial manufacturing.

            The word tractor derives from the Latin verb trahere, meaning “to pull” or “to draw.” The term originally referred to a device or mechanism designed to provide traction — that is, to pull loads. In early agricultural use, the tractor’s primary function was precisely this: to replace animal traction in pulling ploughs and heavy implements. Over time, while its capabilities expanded far beyond simple pulling force, the name remained rooted in its original mechanical purpose.

            From Animal Power to Steam Engines

            Before tractors, farming relied primarily on horses and oxen. In the second half of the 19th century, steam-powered traction engines began to appear in large estates in Europe and North America. These machines were heavy, slow, and required significant maintenance, but they introduced the concept of mechanized field work.

            Steam tractors were powerful enough for plowing and threshing, yet their size and operational complexity limited their diffusion. They were more suited to large farms and industrial-scale agriculture.

            The Internal Combustion Revolution

            The real breakthrough came in the early 20th century with the adoption of gasoline engines. Lighter, more compact, and easier to operate than steam engines, gasoline tractors rapidly replaced animal traction.

            In 1917, the Fordson Model F, produced by Ford Motor Company, became the first mass-produced tractor. This made mechanization accessible to medium and small farmers. Around the same time, companies such as John Deere expanded their presence in the agricultural machinery sector.

            The tractor was no longer a luxury for large estates — it became a practical working tool.

            The Diesel Era and Increased Power

            From the 1930s onward, diesel engines gradually replaced gasoline in most agricultural tractors. Diesel offered higher torque at low speeds, better fuel efficiency, and greater durability under heavy loads.

            Manufacturers such as Massey Ferguson and Fiat Trattori played a key role in expanding tractor production globally, including in Europe.

            During this period, tractors became more specialized. Different horsepower classes were introduced to match specific farm sizes and applications. Attachments and implements multiplied, making the tractor a multifunctional machine rather than just a pulling unit.

            Hydraulics and Versatility

            The introduction of hydraulic systems and the three-point hitch system significantly improved tractor versatility. Operators could now lift, control, and precisely manage mounted implements.

            Cabins, improved transmissions, power steering, and safety standards transformed tractors into more comfortable and efficient machines. By the late 20th century, tractors were engineered platforms integrating mechanics, hydraulics, and increasingly electronics.

            Tractor in Modern Agriculture

            From steam engines to smart, connected systems, the tractor has evolved from a heavy mechanical device into a highly engineered platform combining power, control, and digital intelligence.

            Its history reflects broader industrial progress: advancements in engines, metallurgy, hydraulics, and mechanical design have all contributed to making agriculture more productive and sustainable.

            Understanding the history of the tractor also means understanding the evolution of mechanical components, materials, and engineering solutions that made modern farming possible.

            Fendt tractor exhibited at Agritechnica 2023

            Toward Autonomous and Intelligent Farming

            The next stage of tractor development is no longer defined only by horsepower or mechanical strength, but by intelligence and connectivity. Autonomous driving systems, artificial intelligence, real-time data processing and machine-to-machine communication are gradually transforming tractors into self-optimizing units within a fully digital farm ecosystem.

            Future tractors will increasingly operate with minimal human intervention, adjusting speed, traction, fuel consumption and implement settings automatically based on soil conditions and agronomic data. Predictive maintenance, remote diagnostics and cloud-based fleet management will further reduce downtime and improve operational efficiency.

            As automation advances, the tractor is evolving from a machine operated by a driver into a coordinated, data-driven system — an integral part of precision agriculture and sustainable food production.

            The story of the tractor is therefore still being written, shaped by digital engineering, robotics and artificial intelligence.

            Steel bushings catalog

            Modern tractors operate under higher loads, greater precision requirements, and more demanding duty cycles than ever before. Pivot points, linkage systems, and hydraulic assemblies depend on reliable wear components to ensure durability and consistent performance over time.

              Milan–Cortina 2026 Zamboni Machines

              Zamboni Restoring the Ice Surface

              You may have noticed in recent days, during the ice competitions at the Milan–Cortina 2026 Winter Olympics, the well-known ice resurfacing machines entering the rink between events.

              They are commonly called “Zamboni” — a name that has become an antonomasia. Over time, the brand name has come to identify ice resurfacing machines in general.

              What These Machines Are Used For

              Ice resurfacing machines are essential for sports such as ice hockey, figure skating and short track speed skating. Their job is simple but crucial:

              • they shave off the damaged top layer of ice,

              • collect snow and debris,

              • spread a thin layer of clean water that is leveled and left to freeze.

              This process restores a smooth and even surface, helping ensure consistent and safe conditions for athletes.

              A Story with Italian Roots

              The first model was developed in the 1940s by Frank J. Zamboni, the son of Italian immigrants from Trentino and Piedmont.

              The first machine entered service in 1949 and was later used at the 1960 Winter Olympics. Since then, ice resurfacers have become standard equipment at international ice competitions.

                Excavator Types

                Infographic showing six types of excavators: Mini, Mid, Giant, Rope Shovel, Vacuum, and Bucket Wheel

                The term excavator comes from the Latin verb excavare, meaning “to hollow out” or “to dig out”.
                In mechanical and industrial contexts, it refers to machines that differ greatly in size, structure, and working conditions. A practical and widely used way to classify excavators is by operating weight, as it reflects the machine’s mechanical scale, typical duty cycle, and the loads acting on joints, pins, and bushings.

                Mini Excavators

                Typical operating weight: up to 8 tonnes
                Most common range: 1–6 tonnes

                Mini excavators are designed for confined spaces and precision work. They are widely used in urban construction, utilities, landscaping, and maintenance jobs where compact dimensions and maneuverability matter more than maximum production.

                Mid-Size Excavators

                Typical operating weight: 8–40 tonnes
                Core market range: 15–30 tonnes

                Mid-size excavators are the industry workhorses. They are used across construction, infrastructure, earthmoving, quarrying, and demolition, often with a wide variety of attachments. Compared to mini excavators, they operate under higher loads and more demanding duty cycles, which increases stress and wear at pivot points.

                Giant Excavators (Mining Class)

                Typical operating weight: above 40 tonnes (up to several hundred tonnes)
                Main applications: open-pit mining and large-scale extraction

                Giant excavators are purpose-built for extreme loads and continuous operation. In mining environments, downtime has a major economic impact, so these machines are engineered for high availability and long service intervals. Their joints, pins, and bushings are correspondingly larger and more heavily stressed.

                • Komatsu PC8000

                When people talk about “the biggest excavators in the world,” they often include not only ultra-large hydraulic mining excavators, but also bucket-wheel excavators used in large surface mining operations. Machines such as Bagger 288 and Bagger 293 are famous examples, closer to mobile industrial plants than conventional excavators in both size and operating logic.

                Other Excavator Types: Rope Shovels and Vacuum Excavators

                In addition to hydraulic excavators classified by size, there are other excavator types that follow different working principles and serve very specific applications.

                Rope Shovel Excavators

                Rope shovels (also known as cable shovels) represent one of the earliest forms of mechanical excavation.
                Unlike hydraulic excavators, their movements are controlled by steel cables and winches, a design that predates modern hydraulic systems.

                The first large rope shovels appeared in the early 20th century, during the rapid expansion of mining and large infrastructure projects in North America. Manufacturers such as Bucyrus and Marion Power Shovel became industry leaders, supplying massive machines for open-pit mines, railways, and large-scale earthworks.

                These early rope shovels—initially steam-powered and later electrified—laid the foundation for modern surface mining.
                Even today, rope shovels remain widely used in large mining operations, where their ability to handle extremely high payloads and continuous heavy-duty cycles makes them highly efficient and reliable.

                Vacuum Excavators

                Vacuum excavators are designed for non-destructive digging. Instead of cutting into the ground with a bucket, they remove soil by high-powered suction, often combined with air or water to loosen the material.

                This technology is mainly used in urban and utility applications, such as locating buried services, maintenance work, and trenchless operations, where precision and safety are critical. Vacuum excavators are typically truck-mounted machines and are not intended for high-volume excavation, but for controlled and selective material removal.

                Bushings in Excavators: Materials in Brief

                Across all excavator sizes, bushings are installed in articulated joints to absorb wear, protect structural components, and maintain alignment over time. Material choice depends mainly on loads, shock forces, lubrication strategy, and operating environment.

                • Bronze bushings: good sliding properties and useful where loads are moderate and lubrication may be limited.
                • Sintered bronze: often selected for its self-lubricating behavior in specific conditions.
                • Composite / polymer-based bushings: used in targeted applications, typically where low-friction or corrosion resistance is required under controlled loads.
                • Steel bushings: increasingly common as loads and shock forces rise; often surface-treated or case-hardened for strength and dimensional stability in heavy-duty service.
