A telehandler or a telescopic handler is a machine which is popular within the construction and agriculture industries. These machinery are similar in function and appearance to a forklift or a lift truck but are actually more like a crane instead of a forklift. The telehandler provides improved versatility of a single telescopic boom that can extend upwards as well as forwards from the vehicle. The operator has the ability to attach numerous attachments on the boom's end. Several of the most popular attachments comprise: a bucket, a muck grab, pallet forks or a lift table.
A telehandler typically uses pallet forks as their most popular attachment to be able to move cargo through places that are usually unreachable for a typical forklift. Like for instance, telehandlers could move loads to and from places that are not normally accessible by standard forklift models. These devices can also remove palletized loads from inside a trailer and position these loads in high areas, like on rooftops for example. Previously, this situation mentioned above would require a crane. Cranes could be pricey to utilize and not always a time-efficient or practical option.
One more advantage is also the telehandlers biggest limitation: because the boom raises or extends when the machinery is bearing a load, it also acts as a lever and causes the vehicle to become somewhat unbalanced, 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 instance, a vehicle which has a 5000 pound capacity with the boom retracted might be able to safely lift only as much as 400 pounds once it is completely extended with a low boom angle. The same model with a 5000 pound lift capacity which has the boom retracted might be able to easily support as much as 10,000 pounds with the boom raised up to 70.
England first pioneered the telehandler in 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 section. This positioned the cab of the driver on the machine's back portion, as in the Teleram 40 unit. The rigid chassis design with a rear mounted boom and the cab located on the side has since become more and more popular.
