JLG/Gradall TF6-42 telehandler
The new JLG/Gradall TF6-42 can function as a boom-type aerial-work platform or as a rough-terrain telehandler; and when used as a personnel lift, can be controlled by one person from the platform.

JLG Industries promotes its new JLG/Gradall TF6-42 Transformer as a unique machine. This model is designed to function as either a boom-mounted aerial-work platform or a rough-terrain telehandler, and the "transformation" from one machine to the other requires only 10 minutes. True, says JLG, certain other machines, including some Gradall models, can be equipped with approved accessories for changing the forks on a telehandler into a personnel work platform. But these conversion machines, according to JLG, when used as an aerial-work platform, require two workers—one on the platform and the other in the cab to control the machine.

The TF6-42 Transformer, however, says JLG, can be operated by one person in either configuration. When used as a personnel lift, a single operator, located on the platform, can control the drive and steering functions of the base machine, as well as platform functions. According to the company, the TF6-42 is the only machine that meets both the ANSI A92.5-1992 standards for aerial-work platforms and the ASME B56.6-1998 standards for telehandlers.

The aerial-work platform, measuring 4×8 feet, has a 2,000-pound restricted capacity up to 33 feet, a 1,000-pound capacity up to 38 feet, and 500 pounds of unrestricted capacity at 43 feet, the maximum platform height. Maximum reach with the platform is 30 feet. The platform features 90-degree rotation, right or left, for improved access to hard-to-reach locations.

Used as a rough-terrain, telescopic material handler, the TF6-42, equipped with Gradall controls in its ROPS/FOPS-certified cab, has a rated lift capacity of 6,600 pounds (24-inch load center) and a maximum lift height of 42 feet. Maximum horizontal reach is 28 feet. The base machine features oscillating axles and a 10-degree frame-leveling capability, and it provides travel speeds up to 16 mph (limited to 5 mph from the work platform).

The 22,000-pound Transformer uses a John Deere diesel, rated at 80 gross horsepower, coupled to a Dana VDT-12000 powershift transmission with an integral torque converter. Both axles are powered, and the front axle is equipped with inboard, wet-disc brakes. Four-wheel steering allows coordinated and crab modes, as well as front-wheel only, and all steering options are available also at the platform. The machine's single-section gear pump provides a 40-gpm hydraulic flow.

The low-profile design of the TF6-42 gives the machine an overall height of 94 inches. Overall width is 96 inches, and the machine has a wheelbase of 128 inches. More than 20 attachments are available for the new model, including a truss boom with winch, a selection of buckets, a vertical mast and a drywall carriage. Optional accessories include a cab enclosure, a lockable split door, heater/defroster and cold-weather starting package.
