ZWZA, ZWZB Series DC electromagnetic drum brakes can be extensively used for deceleration and stopping of electromagnetic lifter and various lift, belt transport, port handling, metallurgical and building machinery using DC drive or DC net. They are not suitable for machines using AC drive.
This series brakes is mainly used for taking replace of old products of ZWZ series.
Main Features：
▲ 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.
▲ Brake lining is of clamped integral forming structure, which is easy and quick to replace，There are semi-metallic (non asbestos) hard and semi-hard, soft (non asbestos) and other brake pads of different materials for customers to choose
▲ New type armature iron auto-aligning device which can keep armature iron and magnetic yoke jointing well all the time.
▲ Brake closes in case of power failure (Fail-Safe Principle).Braking by spring power.Electromagnetic release.
