The telehandler or telescopic handler is a heavy duty machine which is well-known in both the agriculture and construction businesses. These machines are quite similar in both appearance and function to the lift truck, except it more closely resembles a crane. The telehandler offers increased versatility of a single telescopic boom which could extend upwards and forwards from the vehicle. The operator could connect numerous attachments on the end of the boom. Some of the most popular attachments comprise: a muck grab, a bucket, pallet forks or a lift table.
To be able to transport cargo through locations that are normally unreachable for a conventional forklift. The telehandler utilizes pallet forks as their most common attachment. For instance, telehandlers could move cargo to and from areas which are not typically reachable by standard forklift units. These devices also have the ability to remove palletized cargo from inside a trailer and place these loads in high places, like on rooftops for example. Previously, this aforementioned situation would need a crane. Cranes can be expensive to utilize and not always a practical or time-efficient alternative.
Another advantage is also the telehandlers largest limitation: as the boom extends or raises when the machine is bearing a load, it also acts as a lever and causes the vehicle to become somewhat unstable, despite the rear counterweights. This translates to the lifting capacity decreasing quickly as the working radius increases. The working radius is the distance between the center of the load and the front of the wheels.
For example, a vehicle which has a 5000 pound capacity with the boom retracted might be able to safely raise just as heavy as 400 pounds once it is fully extended with a low boom angle. The same model with a 5000 pound lift capacity that has the boom retracted may be able to easily support as much as 10,000 pounds with the boom raised up to 70.
England originally pioneered the telehandler within Horley, Surrey. The Matbro Company developed these equipment from their articulated cross country forestry forklifts. At first, they had a centrally mounted boom design on the front portion. This positioned the driver's cab on the machine's back part, like in the Teleram 40 model. The rigid chassis design with the cab situated on the side and a rear mounted boom has since become more and more famous.
