Electro-hydraulic Drum Brake

YWK Series electro-hydraulic drum brakes can be extensively used for the deceleration braking of gantry travelling mechanism of various common-use bridge and gantry cranes, as well as the deceleration braking of driving device of non-hoisting winches.

MAIN FEATURE

Interlocking shoe clearance balancing device and shoe auto-aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brake wheel.

At main hinge points where are equipped with self-lubricating bearings,which make higher efficiency of transmission and longer performance life.

Brake lining is of card-mounted and entirely-shaped structure, which is easy and quick to replace. Brake lining of various materials such as semi-metal (non-asbestos) hard and half-hard, soft (non-asbestos) substance are available for customer to choose.
