A hydraulic forklift uses hydraulic pistons to lift heavy objects with a fork mechanism. The design varies depending on the lift’s size and function, and they can be powered by electricity, petrol, or diesel. Forklifts can have air-filled or solid rubber tires and are used in various settings, including warehouses and retail stores.
A hydraulic forklift is a machine that uses hydraulic lifting devices to lift or lower heavy objects. Hydraulic pistons are cylinders filled with a liquid, usually a type of oil, that can be pressurized to expand or depressurized to contract. A hydraulic forklift will use more than one cylinder mounted on the machine to lift a fork mechanism, which generally has two blades or tines, that slide into a pallet. A forklift can lift objects without a pallet, although the pallet makes the lifting more stable and safer.
Most hydraulic forklift models are equipped with a drive system and the driver will sit in or on the unit. Some designs require the driver to walk behind the unit, controlling the hydraulic lift truck using a yoke or hand lever. Elevator tires can be air-filled tires or solid rubber tires. The type of tires used on the elevator will depend on where the elevator is most likely to be driven – an elevator with solid rubber tires will usually only be used on flat surfaces such as warehouse floors, while pneumatic tires will be used outdoors or on uneven surfaces.
The design of the forklift hydraulic unit will vary depending on the size and function of the lift. Many hydraulic forklift models are equipped with a vertical lift system that lifts the forks straight up. Other models may feature a telescopic arm that extends up and out from the body of the machine. The latter model is often known as a telehandler and is used to lift objects much higher or farther than a standard vertical lift model can accommodate.
Forklifts can be powered in a number of ways – smaller models are often powered by electricity and will be equipped with one or more batteries for operation control. Larger forklifts can be equipped with petrol engines for more power and torque. Larger versions of the hydraulic forklift will be diesel-powered for maximum power and torque. Diesel lifts are usually only used outdoors or in very well ventilated areas, as diesel engines can produce a significant amount of exhaust fumes; they also tend to be quite noisy and can make working conditions quite difficult when used indoors. Narrow forklifts are often used in warehouses or even retail stores with narrow aisles; these are usually electric, although some are also gas powered.
