YWH Series Electro-Hydraulic Drum Brakes

YWH series brakes are normal-closed brakes, suitable for vertical installation. Thruster is horizontally installed with compact construction. The brakes are mainly used for mechanism deceleration and stop/braking of various cranes, belt conveyors, port handling and metallurgical machinery, especially applied to confined installation space on two sides of wheel.

Main design features

  • Interlocking shoes balancing devices (patent technology) constantly equalizes the clearance of brake shoes on both sides and make adjustment unnecessary, thus avoiding one side of the brake lining sticking to the brake wheel.The brake is equipped with a shoes auto-aligning device.
  • Main hinge points are equipped with self-lubricating bearing,making high efficiency of transmission,long service life. Lubricating is unnecessary during operation.
  • 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
  • Brake lining is of card whole-piece shaping structure, easy to replace. Brakes lining of various materials such as half-metal (non-asbestos) hard and half-hard, soft (including asbestos) substance are available for customers to choose.
  • Adopt the company's new types of thruster as corollary equipment which work accurately and have long life.


  • Hand released lever.
  • Release (open) or close limit switch, indicates whether  brake is properly released or closed and realize interlocking protection.
  • Lining-wear limit switch, indicates when wear of lining reaches the limit (Note: self-compensator should be attached simultaneously).
  • Wear-self-compensator effects self-compensation of shoe clearance and torque when lining wears.
  • Adopt thruster with fall delay valve as drive system,this can realize closing delay of brake.
