Forklifts are mobile machines that use 2 forks or prongs in order to place loads into positions that would typically be difficult to reach. Typically, forklifts fall into 2 major categories: industrial and rough-terrain.
Industrial lift trucks are most often utilized around train and truck loading docks in addition to many warehouse operation. These equipment have smaller tires which are designed to run on paved surfaces. Normally, industrial lift trucks are powered by an internal gasoline engine running on diesel fuel or propane.
Smaller forklifts may run off an internal battery charging an electric motor. And as the name implies, the rough terrain lift truck is designed to be operated on rough and unpaved surfaces. Normally, they are the great alternative for construction and military operation. Rough terrain lift trucks generally have large pneumatic tires that are usually powered by internal industrial engines that run on diesel or propane fuel. These lift truck units can have a telescoping boom, that could lift loads up and out from the machine's base or they can utilize a vertical tower, that is responsible for lifting loads straight up.
In 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 equipment was used around construction locations and could lift to a height of 30 inches or 76 centimeters and had a lifting capacity could lift 454 kg or 1000 pounds. Vertical tower forklifts were rapidly developed for industrial use and rough terrain forklifts became popular as well. By the time the 1950s came around, there were available units that could lift up to heights of 9 meters or 30 feet and had lift capacities of 2500 lbs or 1135 kg.
During 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 1362 kg or 3000 lbs. and 35 feet or 11 meters. The first telescoping boom rough terrain forklift emerged on the market during 1962. This model enabled loads to be positioned out from the equipment's base both below and above grade.
