The lift truck is a mobile equipment that uses 2 prongs or forks to lift and place loads into positions that would be usually difficult to reach. Typically, lift trucks fall into 2 major categories: industrial and rough-terrain.
Most often, industrial lift trucks are used around truck loading docks and train loading docks in addition to in warehouse operations. These equipment have smaller tires which are engineered to run on paved surfaces. Typically, industrial lift trucks are powered by an internal gasoline engine running on propane or diesel fuel.
Smaller forklifts 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. Normally, they are the great alternative for military and construction operation. Rough terrain lift trucks generally have large pneumatic tires that are generally powered by internal industrial engines that run on propane, diesel or propane fuel. These lift truck units can have a telescoping boom, capable of lifting cargo up and out from the base of the machine or they could use a vertical tower, which is responsible for lifting cargo straight up.
The rough terrain forklift emerged during the year 1946, after a 2 pronged lift attachment was attached to a tractor chassis or a power buggy. This initial machine was utilized around construction sites and can raise to a height of 30 inches or 76 centimeters and had a lifting capacity could lift 1000 pounds or 454 kg. Vertical tower forklifts were rapidly developed for industrial application and rough terrain lift trucks became popular as well. 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 2500 lbs or 1135 kg.
The original 4-wheel drive rough terrain forklift was introduced in 1958. It offered a capacity of 2724 kg or 6000 lbs. and had a lift height of 7 meters or 22.5 feet or 3000 lbs. or 1362 kg and 35 feet or 11 meters. The very first telescoping boom rough terrain forklift emerged on the market in 1962. This unit allowed cargo to be positioned out from the base of the equipment both above and below grade.
