- Steering and drive axles are fitted with axle oscillation oscillation assemblies to create a stable working platform for work in any direction without the need for outriggers
- Travel speeds up to 12 mph
- Variable displacement high torque piston motor powers two-speed power shift transmission
- Electronically operated travel alarm signals carrier movement
- Variable displacement high torque piston motor powers two-speed power shift-on-the-fly transmission
- Automatic spring-set/hydraulic release wet-disc parking brake
- Dynamic braking is provided by the hydraulic system
- Deliver appropriate scaling power without wasting fuel using the two-section telescoping boom that’s armed with high-pressure, load sensing hydraulics
- Full boom telescopes and tilts 220° to address hard-to-reach prying locations and avoid overhead obstructions
- All hydraulic hoses are located safely inside the boom
- Double rollers handle rigors of scaling
- Consistent boom force through the entire dig cycle
- Rugged boom telescopes out to 48’ 9”
- Low profile operation for work beneath low ceilings
- Full-length boom visibility during the entire dig cycle
- Choose the Gradall, Deere or SAE joystick pattern using an in-cab switch
- All-weather cab has tinted safety glass, acoustical lining, filtered fresh air heater, defroster and A/C
- Front window has heat-resistant glass
- Tilting, telescoping steering column provides smooth, comfortable steering
- Hydraulic foot pedal controls braking functions
