There are various types of forklift and they differ in terms of capacity and the power source used, among other things. Amongst these are battery-, diesel- and gas-powered forklifts. Gas forklifts run on Compressed Natural Gas, Liquid Petroleum Gas or, alternatively, on petrol. Diesel forklifts are the most common kind used in South African industry.
Forklifts lift and move goods like containers and pallets in warehouses and many other different applications. In order to do this, a forklift has a very particular construction. The major parts include the body, onto which a solid, heavy counterweight is fitted to the back to balance the forklift when it is lifting a load. There is also a cab, usually fitted with a strong roof that doubles as a safety guard to protect the driver. It is fitted with a mast and tilt cylinders that work together to engage the load. In most cases, safety devices cut engine power and lock the mast and tilt cylinders when the operator leaves his seat. Lastly, in the case of diesel forklifts, is the internal combustion diesel engine.
Confined spaces are more suited to battery-driven forklifts, because they are generally more compact and a diesel forklift would emit diesel fumes that would be undesirable in small or poorly ventilated areas. Diesel forklifts are ideal in large, ventilated areas. They can maintain a longer and more intense work rate, needing to stop for diesel only.
Typical places one would find diesel forklifts at work are outside warehouses, production plants, nurseries, storage facilities; in fact, any place where heavy goods need to be stored, retrieved, lifted or moved. They feature rear-wheel steering to aide manoeuvrability and they should only be used by trained personnel who are aware of the vehicle’s inherent instability. A forklift’s centre of gravity changes while engaging and lifting loads and serious accidents can occur as a result of this.
