The lift truck is a mobile machine which utilizes 2 forks or prongs to carry and place cargo into positions that would be normally difficult to reach. Normally, lift trucks fall into 2 major categories: industrial and rough-terrain.
Industrial lift trucks are most often utilized around truck and train loading docks in addition to many warehouse applications. These machines have smaller tires that are designed to run on smooth surfaces. Normally, industrial lift trucks are powered by an internal gasoline engine running on propane or diesel fuel.
Smaller lift trucks may run off an internal battery charging an electric motor. And as the name implies, the rough terrain forklift is engineered to be operated on unpaved and rough surfaces. Commonly, they are the ideal choice for military and construction applications. Rough terrain forklifts normally have big pneumatic tires that are generally powered by internal industrial engines that run on propane, diesel or propane fuel. These forklift units could have a telescoping boom, capable of carrying cargo up and out from the machine's base or they could use a vertical tower, which is responsible for carrying loads straight up.
During the year 1946, the rough terrain forklift emerged as a 2 pronged lift attachment was placed on a tractor chassis or a power buggy. This first machinery was used around construction sites and could raise to a height of 76 cm or 30 inches and had a lifting capacity can carry 1000 pounds or 454 kg. Vertical tower forklifts were quickly developed for industrial use and rough terrain lift trucks became popular too. By the time the 1950s came around, there were models available that can lift up to heights of 30 feet or 9 meters and had lift capacities of 1135 kg or 2500 pounds.
In 1958, the first 4-wheel drive rough terrain lift truck was introduced with a capacity of 2724 kg or 6000 lbs. and had a lift height of 7 meters or 22.5 feet or 1362 kg or 3000 lbs. and 35 feet or 11 meters. The first telescoping boom rough terrain lift truck emerged on the market in the year 1962. This particular unit enabled loads to be positioned out from the base of the equipment both below and above grade.
