Electro-hydraulic Drum Brakes can be extensively used for various mechanism deceleration and stop/braking of various belt transport,port handling,hoisting, metallurgical, mining and building machinery.
The dimensions and braking torque parameters of YWZ5/YWZ9 series brakes comply with GB6333-86 standard,technology requirements comply with JB/T6406-2006 standard.（Table.1）
Main Feature：
● Brake lining is of clamped integral forming structure, which is easy and quick to replace.
● 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.
● Main hinge points are equipped with self-lubricating bearing ,making high efficiency of transmission ,long ser vice life. Lubricating is unnecessary during operation.
●Enclosed spring tube protects spring from damage and contamination.
● The Ed series thrusters are characterized by flexible action and long operating life.
● Brake closes in case of power failure (Fail-Safe Principle).Braking by spring power.Lifting by thruster.
