Main design features
■Interlocking shoe clearance balancing device (patented technology) 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 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 then 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 half-hard, soft (include asbestos) substance are available for customer to choose.
■New type armature iron auto-aligning device which can keep armature iron and magnetic yoke jointing well all the time.
