Main Design Features

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

At main hinge points are equipped with self-lubricating bearings, which make higher efficiency of transmission and longer performance life, and lubricating is unnecessary during the course of operation.

Brake spring is arranged inside square tube and surveyor’s rod is placed on one side. It is easy for customers to read braking torque value and avoid the troubles of measuring and computing.

Brake lining is of card whole piece shaping structure, which is easy and quick to replace. Brake lining of various materials such as half metal ( non-asbestos) hard and haft-hard, soft (include asbestos) substance are available for customer to choose.
