Pettibone has designed the boom for its new Extendo 944X telehandler to add strength but reduce weight.
The design, which includes formed boom plates, also minimizes boom deflection for better control and accuracy when placing loads, the company says.
The boom has a maximum lift capacity of 9,000 pounds, max forward reach of 30 feet and max lift height of 44 feet, 6 inches.
Pettibone has nearly doubled boom overlap from previous models, which makes for smoother operation and less force on wear pads. A bottom-mounted external extend cylinder also reduces the load on the wear pad in half. All of this serves to extend the machine’s service life, and the location of the cylinder makes service access easier to internal boom components, the company says. Service is further simplified by fasten-less wear pads and a single extension chain instead of having to balance dual chains.
Cylinder cushioning has been added to smooth out extension and retraction to prevent hard, jarring stops that cause wear and tear and loads to spill. The telehandler’s single lift cylinder also improves sight lines. It features twin non-tensioned hydraulic lines for tilt and auxiliary plumbing.
The telehandler runs on a 74-horsepower Cummins QSF 3.8 Tier 4 final diesel engine, which is mounted on a side pod to improve service access and curbside visibility and to provide ground clearance of 18 inches. A 117-horsepower model is optional.
The company says the 944X is built for rough terrain, featuring four-wheel drive and limited-slip front axle differential. The Dana Powershift transmission offers three speeds, forward and reverse. Turning radius is 14 feet, 1 inch.
The cab features enhanced climate control, flat bolt-in glass and a split-door design. The rear window opens, and lockable storage is provided beneath the ergonomic seat. A USB accessory plug has been added. The components are water resistant, so they can be washed easily. The cab also features an ergonomic pedal, joystick and steering wheel. A new analog/LCD gauge cluster is standard, and a 7-inch digital display with backup camera is optional.
The telehandler’s fuel and hydraulic tanks are built of damage-resistant steel. The 30-gallon fuel tank has a lockable fuel-fill. Other features include non-tensioned boom hoses, split-system electrical circuit panels, a 12-volt accessory plug in the engine bay, and heavy-duty bright LED lighting. A sling hook for additional load security and a variety of attachments are available as options.
