Heavy equipment or heavy machinery refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations or other large construction tasks. Heavy equipment usually comprises five equipment systems: implementation, traction, structure, power train, control and information.[1]

Heavy equipment has been used since at least the 1st century BCE when the ancient Roman engineer Vitruvius described a crane in De architectura when it was powered via human or animal labor.

Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion.

The first commercial continuous track vehicle was the 1901 Lombard Steam Log Hauler. The use of tracks became popular for tanks during World War I, and later for civilian machinery like the bulldozer. The largest engineering vehicles and mobile land machines are bucket-wheel excavators, built since the 1920s.

"Until almost the twentieth century, one simple tool constituted the primary earthmoving machine: the hand shovel – moved with animal and human powered, sleds, barges, and wagons. This tool was the principal method by which material was either sidecast or elevated to load a conveyance, usually a wheelbarrow, or 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 plane, levers, 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."[2]

Container cranes were used from the 1950s and onwards, and made containerization possible.

Nowadays such is the importance of this machinery, some transport companies have developed specific equipment to transport heavy construction equipment to and from sites.

Most of the major equipment manufacturers such as Caterpillar,[3] Volvo,[4] Liebherr,[5] and Bobcat have released or have been developing fully or partially electric-powered heavy equipment. Commercially-available models and R&D models were announced in 2019 and 2020.[6]

Robotics and autonomy has been a growing concern for heavy equipment manufacturers with manufacturers beginning research and technology acquisition.[7] A number of companies are currently developing (Caterpillar and Bobcat) or have launched (Built Robotics) commercial solutions to the market.
