Power transmission specialist Altra Industrial Motion has developed the next generation of its Twiflex dragline brakes package.
Due to how dragline bucket excavators are designed, there are few brakes that will work. Spring-applied, air-release caliper brakes are among the select few that can handle the challenging task.
Altra Industrial Motion, in conjunction with a large OEM designed a range of these brakes for use on the mining industry’s dragline excavators around 20 years ago. More than 8000 of the resulting Twiflex brakes have since been installed in mines across the world.
The company has updated the Twiflex range to make them more environmentally friendly and even easier to maintain.
The next evolution of brake pads use organic material that are completely asbestos free and have no health impacts on humans and no contaminants or oils.
“The compositions of the diaphragms in the thrusters have been upgraded to make the Thrusters even more reliable, and the overall simple design makes it easy and effective to install and maintain.”
The complete package includes brake callipers, thrusters, mounting frames, mounting bolts, brake discs, hubs, air-pressure regulators, local piping, and guards.
The brakes are also designed to be modular, allowing for quick changeout. The only part that needs to be changed out in its normal life cycle is the brake pad itself, which feature a wear indicator to let staff know when replacements are needed.
