A major Australian coal mine operator needed to replace the brakes on the dragline at their mine in the Bowen Basin. In constant operation since 2011, the dragline’s original braking systems had reached their useful service life.
With a working weight of 6,950 tons and a bucket capacity of 152 yd3, the massive dragline can move 240 tons of overburden in a single pass.
Twiflex was selected to provide spring-applied, air-released replacement caliper brakes for all the dragline’s motors:
The GMR-SD caliper brake’s modular design allows for quick change outs and the ability to use multiple units of varying sizes to meet specific installation requirements. Torque is adjusted in the field to meet operating conditions. The low-maintenance brakes feature easy-to-replace brake pads and low cost spares.
