MAIN FEATURE

01

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. 

02

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 (include asbestos) substance are available for customer to choose.

03

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

04

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.

05

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

ADDITIONAL DEVICES

Hand release lever.

Lining-wear limit-switch, equipped which signals will be shown when wear of lining reaches the limit (note: self-compensation device should be equipped in application).

Open(Release) or close limit-switch, which indicates whether the brake is properly released or closed.

When use such thrusters that with descending delay valve,the delay close of brake can be realized,which can meet the requirements of some special occasions.
