Gradall Mine Scaling Machines Rotate Powerful Boom to Achieve High Productivity at Hard-To-Reach Angles

Even in hard-to-reach headwall locations, Gradall mine scaling machines set a new productivity standard.

Maneuvering into position on rubber tires, the steering axle is fitted with an axle oscillation assembly to create a stable working platform without the need for outriggers. Or, choose a crawler undercarriage for exceptional stability, even on uneven terrain.

The entire telescoping, triangular boom fully tilts 270 or 220 degrees, depending on the model. This unique boom tilt capability allows the operator to accurately place the bucket or prying tool for productive mine scaling.

Delivering appropriate scaling power without wasting fuel, the two-section boom is armed with high-pressure, load-sensing hydraulics. Several features enable the machine to withstand the rigors of mine scaling, including hydraulic hoses located safely inside the boom and double boom rollers.

The boom telescopes out up to 52 feet, 3 inches, delivering consistent boom force throughout the prying and dig cycle. Unlike conventional booms, the Gradall telescoping movement also enables the machine to work beneath low ceilings and provides the operator with a constant clear view of boom movements.

Series V models are powered by a single Volvo Penta engine that meets the highest global standards including State IV (EU) and Tier 4f emissions standards.

Wheeled models can travel at speeds up to 12 mph; a variable displacement high torque piston motor powers a two-speed power shift transmission. Maximum crawler mobility speed is 3.4 mph.

The operator cab provides excellent protection as well as comfort, including filtered fresh air, heater, defroster and air conditioner along with heat-resistant glass. A comfortable seating module integrates joystick controls, operating with a Gradall, Deere or SAE pattern selected with an in-cab switch.

All Gradall mine scaling machines are designed and manufactured only in the U.S.A. at the Gradall Industries complex in New Philadelphia, Ohio. Worldwide parts and service support is provided by a network of distributors and factory-based Gradall representatives.
