Industrial forklifts are very useful on construction sites, as they can be used to transport heavy building materials over fairly long distances, across rough terrain. They combine the functions of a vehicle and a lifting tool. Forklifts can unload pallets of bricks, steel girders and other construction products from the delivery truck and carry them to parts of the construction site that are not accessible to other vehicles.
Forklift hydraulics control hydraulic valves directly by levers or power actuated actuators, using small “finger” levers for control. The latter allows forklift designers more freedom in ergonomic design.
Forklift trucks are available in many variations and load capabilities. In a typical warehouse system, most forklifts have a load capacity of one to five tons. Large engines with a lifting capacity of up to 50 tons are used to lift heavy loads, including loaded container containers.
