A wheeled bulldozer in an open pit coal mine A portable engine ; a precursor to modern engineering vehicles An early gasoline-powered tractor The use of heavy equipment has a long history; the ancient Roman engineer Vitruvius 1st century BCE gave descriptions of heavy equipment and cranes in ancient Rome in his treatise De architectura.
The pile driver was invented around The first tunnelling shield was Heavy machinery by Marc Isambard Brunel in From horses, through steam, to diesel[ edit ] Heavy equipment circa horse-drawn scraper digging water-supply ditch Until the 19th century and into the early 20th century heavy machines were drawn under human or animal power.
With the advent of portable steam-powered engines the drawn machine precursors were reconfigured with the new engines, such as the combine harvester.

Among Japanese and Korean firms with "heavy industry" in their names, many are also manufacturers of aerospace products and defense contractors to their respective countries' governments such as Japan's Fuji Heavy Industries and Korea's Hyundai Rotema joint project of Hyundai Heavy Industries and Daewoo Heavy Industries.|
The design of a core tractor evolved around the new steam power source into a new machine core traction enginethat can be configured as the steam tractor and the steamroller. During the 20th century, internal-combustion engines became the major power source of heavy equipment. Kerosene and ethanol engines were used, but today diesel engines are dominant.
Mechanical transmission was in many cases replaced by hydraulic machinery. The early 20th century also saw new electric-powered machines such as the forklift. The first mass-produced heavy machine was the Fordson tractor in The first commercial continuous track vehicle was the Lombard Steam Log Hauler.
The use of tracks became popular for tanks during World War Iand later for civilian machinery like the bulldozer. The largest engineering vehicles and mobile land machines are bucket-wheel excavatorsbuilt since the s. This tool was the principal method by which material was either sidecast or elevated to load a conveyance, usually a wheelbarrowor a cart or wagon drawn by a draft animal.
In antiquity, an equivalent of the hand shovel or hoe and head basket—and masses of men—were used to move earth to build civil works.
Builders have long used the inclined planelevers, and pulleys to place solid building materials, but these labor-saving devices did not lend themselves to earthmoving, which required digging, raising, moving, and placing loose materials.
The two elements required for mechanized earthmoving, then as now, were an independent power source and off-road mobility, neither of which could be provided by the technology of that time. Nowadays such is the importance of this machinery, some transport companies have developed specific equipment to transport heavy construction equipment to and from sites.
