Electromagnetic Drum Brakes

DC electromagnetic drum brakes can be mainly used for deceleration and stopping of electromagnetic lifter,belt transport, port handling, metallurgical and building machinery using DC drive or DC net. And not suitable for machines using AC drive.

MAIN FEATURE

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.

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

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 then avoid the troubles of measuring and computing.

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 (non-asbestos) substance are available for customer to choose.

New type armature iron auto-aligning device,which can keep armature iron and magnetic yoke jointing well all the time.
