The telehandler or telescopic handler is a heavy duty machinery which is well-known in both the construction and agriculture industries. These equipment are quite similar in both appearance and function to the lift truck, except it more closely resembles a crane. The telehandler provides improved versatility of a single telescopic boom that could extend forwards as well as upwards from the vehicle. The operator could connect many attachments on the boom's end. Several of the most popular attachments comprise: a muck grab, a bucket, pallet forks or a lift table.
A telehandler typically uses pallet forks as their most popular attachment in order to move loads through places that are normally unreachable for a standard forklift. For example, telehandlers could transport cargo to and from areas which are not normally accessible by conventional forklift models. These devices also have the ability to remove palletized loads from within a trailer and position these loads in high areas, like on rooftops for example. Before, this situation mentioned above would require a crane. Cranes could be expensive to utilize and not always a time-efficient or practical choice.
Telehandler's are unique in that their advantage is also their largest drawback: since the boom raises or extends 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 front of the wheels and the center of the load.
When it is fully extended with a low boom angle for instance, the telehandler will just have a 400 pound weight capacity, whereas a retracted boom can support weights as much as 5000 pounds. 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 lb. with the boom raised up to 70.
The Matbro Company within Horley, Surrey, England first pioneered telehandlers. These equipment were developed from their articulated cross country forestry forklifts. Initially, they had a centrally mounted boom design on the front section. This placed the driver's cab on the equipment's rear portion, like in the Teleram 40 model. The rigid chassis design with the cab situated on the side and a rear mounted boom has ever since become more popular.
