Forklifts are mobile equipment that use 2 forks or prongs to be able to place loads into positions which will normally be hard to reach. Typically, lift trucks fall into 2 major categories: rough-terrain and industrial.
Most often, industrial forklifts are used around truck loading docks and train loading docks in addition to in warehouse operations. These machines have smaller tires that are designed to run on smooth surfaces. Normally, industrial forklifts 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 rough and unpaved surfaces. Normally, they are the great option for construction and military operation. Rough terrain forklifts generally have big pneumatic tires that are generally powered by internal industrial engines that run on diesel or propane fuel. These forklift models can have a telescoping boom, which can lift loads up and out from the base of the machinery or they could utilize a vertical tower, that is responsible for carrying loads straight up.
The rough terrain lift truck emerged during 1946, after a 2 pronged lift attachment was attached to a tractor chassis or a power buggy. This first machine was used around construction sites and can lift to a height of 30 inches or 76 centimeters and had a lifting capacity can lift 454 kg or 1000 pounds. Vertical tower forklifts were rapidly developed for industrial application and rough terrain lift trucks became popular too. By the time the 1950s came around, there were available units that could raise up to heights of 30 feet or 9 meters and had lift capacities of 2500 pounds or 1135 kg.
The first 4-wheel drive rough terrain forklift was introduced during the year 1958. It offered 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 35 feet or 11 meters. The very first telescoping boom rough terrain forklift emerged on the market in 1962. This unit allowed loads to be placed out from the equipment's base both above and below grade.
