Forklifts are mobile equipment that use 2 forks or prongs to be able to place loads into positions which would usually be difficult to reach. Typically, lift trucks fall into 2 major categories: industrial and rough-terrain.
Industrial forklifts are most commonly utilized around truck and train loading docks in addition to many warehouse operation. These machines have smaller tires which are engineered to run on paved surfaces. Normally, industrial forklifts are powered by an internal gasoline engine running on diesel fuel or propane.
There are some smaller industrial forklift units which use an electric motor running off an internal battery. As the name implies, rough terrain forklifts are engineered to run on rough and unpaved surfaces. Usually, they are the great alternative for construction and military operation. Rough terrain lift trucks generally have large pneumatic tires that are normally powered by internal industrial engines that run on propane, diesel or propane fuel. These lift truck units could have a telescoping boom, that can carry loads up and out from the base of the machine or they may utilize a vertical tower, that is responsible for carrying cargo straight up.
During the year 1946, the rough terrain lift truck emerged as a 2 pronged lift attachment was placed on a tractor chassis or a power buggy. This initial machine was utilized around construction sites and could lift to a height of 76 cm or 30 inches and had a lifting capacity could lift 1000 pounds or 454 kg. Vertical tower forklifts were quickly developed for industrial application and rough terrain lift trucks became famous too. By the time the 1950s came around, there were available units that could lift up to heights of 30 feet or 9 meters and had lift capacities of 1135 kg or 2500 pounds.
In 1958, the original 4-wheel drive rough terrain forklift was introduced with a capacity of 2724 kg or 6000 lbs. and had a lift height of 22.5 feet or 7 meters or 3000 lbs. or 1362 kg and 11 meters or 35 feet. The first telescoping boom rough terrain lift truck emerged on the market in the year 1962. This specific model allowed cargo to be placed out from the equipment's base both above and below grade.
