Twiflex Ltd., part of Altra Industrial Motion, has introduced a new disc brake for mining and conveyor applications. The VBS modular brake features large pads and IP65 protection, making it ideal for high speed conveyor drives in mining and quarrying applications. The brake also benefits from Twiflex’s ‘Parked Off’ safety feature; the only system of its kind to allow completely safe maintenance and pad removal.
Over the past 20-30 years, the main technological development in brakes for mine hoists has been the replacement of less efficient drum brakes with hydraulic disc brakes.
A major elevator OEM specifies Twiflex VKSD disc brakes for use on high-performance elevator drives installed in skyscrapers. The dual function brakes stop the elevator cars precisely at the correct floor level and also decelerate the cars in an emergency (such as a malfunction).
