Forklifts are mobile machinery that use 2 forks or prongs in order to place loads into positions which will usually be hard to reach. Typically, forklifts fall into 2 major categories: industrial and rough-terrain.
Most often, industrial lift trucks are utilized around train loading docks and truck loading docks along with in warehouse operations. These machinery have smaller tires which are designed to run on smooth surfaces. Usually, industrial forklifts are powered by an internal gasoline engine running on propane or diesel fuel.
There are several smaller industrial forklift units which utilize an electric motor running off an internal battery. As the name implies, rough terrain forklifts are designed to run on unpaved and rough surfaces. Normally, they are the great option for military and construction applications. Rough terrain lift trucks normally have big pneumatic tires which are normally powered by internal industrial engines that run on diesel or propane fuel. These lift truck units can have a telescoping boom, capable of lifting loads up and out from the base of the machinery or they can use a vertical tower, that is responsible for carrying 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 first machine was used around construction locations and can lift to a height of 76 centimeters or 30 inches and had a lifting capacity could carry 454 kg or 1000 pounds. Vertical tower forklifts were quickly developed for industrial application and rough terrain forklifts became popular too. By the time the 1950s came around, there were units available which could lift up to heights of 9 meters or 30 feet and had lift capacities of 1135 kg or 2500 pounds.
During 1958, the original 4-wheel drive rough terrain lift truck was introduced with a capacity of 2724 kg or 6000 lbs. and had a lift height of 22.5 feet or 7 meters or 1362 kg or 3000 lbs. and 11 meters or 35 feet. The first telescoping boom rough terrain lift truck emerged on the market in 1962. This specific unit allowed cargo to be placed out from the base of the machine both below and above grade.
