Forklifts are mobile equipment which utilize 2 prongs or forks in order to place loads into positions which would normally be difficult to reach. Typically, forklifts fall into 2 major categories: industrial and rough-terrain.
Industrial forklifts are most often utilized around truck and train loading docks in addition to many warehouse applications. These machines have smaller tires which are engineered to run on smooth surfaces. Normally, industrial lift trucks are powered by an internal gasoline engine running on diesel fuel or propane.
Smaller lift trucks 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 unpaved and rough surfaces. Commonly, they are the great choice for military and construction operation. Rough terrain lift trucks normally have large pneumatic tires which are usually powered by internal industrial engines which run on propane, diesel or propane fuel. These lift truck models can have a telescoping boom, which could carry cargo up and out from the equipment's base or they can utilize a vertical tower, that is responsible for carrying loads straight up.
During 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 machinery was used around construction locations and can lift to a height of 76 cm or 30 inches and had a lifting capacity can carry 454 kg or 1000 pounds. Vertical tower forklifts were quickly developed for industrial use and rough terrain forklifts became popular too. By the time the 1950s came around, there were models available which could raise 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 during 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 first telescoping boom rough terrain lift truck emerged on the market during the year 1962. This model enabled loads to be positioned out from the equipment's base both below and above grade.
