YWZ4（Ed）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 YWZ4 series brakes comply with JB/ZQ4388-86 standard,technology requirements comply with JB/T6406-2006 standard.
They are equipped with Ed series thrusters which comply with DIN15430 standard.
Main Feature：
Brake lining is of clamped integral forming structure, which is easy and quick to replace.
Main hinge points are equipped with self-lubricating bearing ,making high efficiency of transmission ,long ser vice life. Lubricating is unnecessary during operation.
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.
