A telescopic handler, telehandler or teleporter is a machine widely used in agriculture and industry. It is similar in appearance and function to a forklift but is more a crane than forklift, with the increased versatility of a single telescopic boom that can extend forwards and upwards from the vehicle. On the end of the boom the operator can fit one of several attachments, such as a bucket, pallet forks, muck grab, or winch.
In industry the most common attachment for a tele-handler is pallet forks and the most common application is to move loads to and from places unreachable for a conventional forklift. For example, telehandlers have the ability to remove palletised cargo from within a trailer and to place loads on rooftops and other high places. The latter application would otherwise require a crane, which is not always practical or time-efficient.
In agriculture the most common attachment for a tele-handler is a bucket or bucket grab, again the most common application is to move loads to and from places unreachable for a 'conventional machine' which in this case is a wheeled loader or backhoe loadal. For example, telehandlers have the ability to reach directly into a high-sided trailer or hopper. The latter application would otherwise require a loading ramp, conveyor, or similar.
The telehandler can also work with a crane jib along with lifting loads, that attachments that include on the market are dirt buckets, grain buckets, rotators, power booms. The agricultural range can also be fitted with three point linkage and power take-off. This make the telehandler a truly universal piece of equipment.
The advantage of the telehandler is also its biggest limitation: as the boom extends or raises while bearing a load, it acts as a lever and causes the vehicle to become increasingly unstable, despite counterweights in the rear. This means that the lifting capacity quickly decreases as the working radius (distance between the front of the wheels and the centre of the load) increases. When used as a loader the single boom (rather than twin arms) is very highly loaded and even with careful design is a weakness. A vehicle with a 5,000lb (2.2ton) capacity with the boom retracted may be able to safely lift as little as 400lb (225kg) with it fully extended at a low boom angle. The same machine with a 5,000lb lift capacity with the boom retracted may be able to support as much as 10,000lb (5ton) with the boom raised to 70°. The operator is equipped with a load chart which helps him determine whether a given task is possible, taking into account weight, boom angle and height. Failing this, most telehandlers now utilize a computer which uses sensors to monitor the vehicle, and will warn the operator and/or cut off further control input if the limits of the vehicle are exceeded, the latter being a legal requirement in Europe controlled by EN15000. Machines can also be equipped with front stabilizers which extend the lifting capability of the equipment while stationary, as well machines with are fully stabilised with rotary joint between upper and lower frames, which can be called mobile cranes although they can typically still use a bucket, and are also often referred to as 'Roto' machines. They are a hybrid between a Telehandler and small crane.
Telehandlers were pioneered by the Matbro company at Horley in Surrey, England, UK who developed them from their articulated cross country forestry forklifts. At first they had a centrally mounted boom on the front section, with the driver's cab on the rear section, as in the Teleram 40, but the rigid chassis design with a rear mounted boom and cab to the side has become more popular.
