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,  easy to replace. Brake linings of various materials such as semi-metal (non-asbestos) hard and half-hard, soft (including asbestos) substance are available for customers 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

Adjustable bracket ensure the brake works well. 

05

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 torque value and avoid measuring and computing.

06

All adopt the company's new types of thruster as corollary equipment which work accurately and  have long life.

STANDARDS COMPLIANT

YWW Series

The YWW series Electro-hydraulic brake is normally closed brake, it is mainly used for braking of slewing mechanism required parking location.The technology requirements comply with JB/T6406-2006 standard,and equipped Ed thrusters comply with DIN15430 standard.

YKW Series

The YKW series brake is normally opened brake,it is mainly used for braking of slewing mechanism which is unnecessary to or can not locate while parking. Its technology requirements comply with JB/T6406-2006 standard, and equipped Ed thrusters comply with DIN15430 standard.

ADDITIONAL DEVICES

Only YWW Series

Hand released lever.

Wear-self-compensation device, which realizes endless self-compensation of shoe clearance and torque when lining wears.

Release (open) limit switch, which indicates whether brake is properly released.

Lining-wear limit switch, which indicates signals when wear of lining reaches the limit (Note: self-compensator should be equipped in application)
