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.

04

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

05

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.

06

The equipped series of thrusters are characterized by flexible action and long operating life.

STANDARDS COMPLIANT

YWH Series

The dimensions and braking torque parameters of YWH series brakes comply with JB/T6406-
2006 and DIN15435 standard, they are equipped with Ed series thrusters which comply with DIN15430 standard. 
This series brakes are mainly used for minor installation room and where YW,YWZ2,YWZ4 series can't be installed. 

ADDITIONAL DEVICES

Hand release lever.

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

With pad wear compensating device can realize the stepless self-compensation of shoe clearance and brake torque when pad worn.

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).
