■Interlocking shoes balancing devices (patented technology) constantly equalizes the clearance of brake shoes.shoes on both sides and make adjustment unnecessary, thus avoiding one side of the brake lining sticking to the brake wheel.
The brake is equipped with a shoes auto-aligning device.
■Main hinge points are equipped with self-lubricating bearing ,making high efficience of transmission ,long ser vice life. Lubricating is unnecessary during operation.
■Adjustable bracket ensure the brake works well.
■The brake spring is arranged inside a square tube and a surveyor’s rod is placed on one side. It is easy to read braking toque value and avoid measuring and computing.
■Brake lining is of card whole-piece shaping structure ,easy to replace. Brake linings of various materials such as half-metal (non-asbestos)hard and half-hard, soft (non-asbestos),substance are available for customers to choose.
■All adopt the company’s new types of thruster as corollary equipment which work accurately and have long life.
