In the last ten years, telehandlers, also known as rough terrain variable reach forklifts, have exceeded the reputation of powered mobile equipment. These machinery have become the gem of the construction industry and with excellent reason. These machines are practical, versatile and extremely powerful. Since the number of models and manufacturers has exploded over the last 5 years or so, there are currently a few of these machines readily offered on the market.
In technical terms, a telehandler is considered to be an ITA* Class 7 Powered Industrial Truck. This description means it is a rough terrain forklift, but just in name only. Any of the similarities between a telehandler and a vertical mast type forklift literally ends on sight and on operation. There are some other major differences between the two machines discussed below.
A telehandler has a completely different appearance since it is equipped with a horizontal boom rather than a vertical mast. From a distance, a telehandler with a jib attachment could look more like a mobile crane rather than a lift truck. The boom can telescope or retract and extend as long as 30 feet and beyond depending on the specific unit. The boom can also elevate to an angle from horizontal to around 70 degrees. Telehandlers have been called "zoom booms" due to their ability to telescope. This name has become rather famous with the operators.
One more optional boom related function is called a "Transaction". The telehandler equipped with this option mounted on the chassis. When the operator activates it, the boom will move forward and back for distances up to 8 feet or more. One of the key benefits of this function is that it allows the forks to be cleanly withdrawn from a load and the forks can be cleanly inserted under, regardless of the boom angle.
Zoom booms have changed the construction industry. They are able to accomplish many tasks that used to take a lot more time and man-power to complete.
