Forklifts are mobile machines which utilize 2 prongs or forks in order to place cargo into positions that would normally be difficult to reach. Normally, lift trucks fall into 2 major categories: rough-terrain and industrial.
Industrial forklifts are most commonly utilized around truck and train loading docks in addition to many warehouse applications. These equipment have smaller tires which are engineered to run on paved surfaces. Typically, 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. Usually, they are the ideal choice for construction and military applications. Rough terrain forklifts usually have large pneumatic tires which are usually powered by internal industrial engines which run on diesel or propane fuel. These lift truck units can have a telescoping boom, which can carry loads up and out from the base of the machine or they may use a vertical tower, that is responsible for lifting cargo straight up.
During the year 1946, the rough terrain forklift emerged as a 2 pronged lift attachment was placed on a tractor chassis or a power buggy. This initial machinery was used around construction sites and was able to lift to a height of 30 inches or 76 centimeters and had a lifting capacity can carry 454 kg or 1000 pounds. Vertical tower forklifts were quickly developed for industrial use and rough terrain lift trucks became famous too. By the time the 1950s came around, there were available units which can raise 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 lift truck was introduced with a capacity of 6000 lbs. or 2724 kg and had a lift height of 22.5 feet or 7 meters or 3000 lbs. or 1362 kg and 35 feet or 11 meters. The very first telescoping boom rough terrain forklift emerged on the market in 1962. This particular unit allowed loads to be positioned out from the equipment's base both below and above grade.
