A telehandler or a telescopic handler is a machine which is popular within the agriculture and construction businesses. These equipment are similar in appearance and function to a lift truck or a forklift but are really more like a crane instead of a forklift. The telehandler offers increased versatility of a single telescopic boom which could extend forwards and upwards from the vehicle. The operator could attach various kinds of attachments on the boom's end. Several of the most common attachments consist of: a bucket, a muck grab, a lift table or pallet forks.
In order to move cargo through places which are usually unreachable for a conventional forklift. The telehandler uses pallet forks as their most common attachment. For example, telehandlers are able to move cargo to and from locations which are not typically reachable by conventional forklift units. These devices could also remove palletized loads from in a trailer and place these loads in high locations, such as on rooftops for example. Previously, this aforementioned situation would require a crane. Cranes could be really expensive to utilize and not always a practical or time-efficient option.
Telehandler's are unique in that their advantage is also their largest drawback: since the boom raises or extends when the machinery is bearing a load, it also acts as a lever and causes the vehicle to become quite unstable, even with the rear counterweights. This translates to the lifting capacity decreasing quickly as the working radius increases. The working radius is the distance between the front of the wheels and the center of the load.
For example, a vehicle that has a 5000 lb. capacity with the boom retracted may be able to safely lift only as much as 400 pounds when it is fully extended with a low boom angle. The same unit with a 5000 pound lift capacity that has the boom retracted might be able to easily support as heavy as 10,000 lb. with the boom raised up to 70.
England originally pioneered the telehandler in Horley, Surrey. The Matbro Company developed these machinery from their articulated cross country forestry forklifts. At first, they had a centrally mounted boom design on the front section. This placed the driver's cab on the machinery's rear part, like in the Teleram 40 model. The rigid chassis design with a rear mounted boom and the cab located on the side has ever since become more popular.
