MW710-8000 series electromagnetic drum brakes are normally‑closed, heavy‑duty AC electromagnetic drum brakes, designed for high‑torque braking, safety holding and emergency stopping in large‑scale hoisting, port, metallurgical and heavy industrial machinery.
Basic Identification
Model: MW710-8000 Series
Type: Heavy-duty electromagnetic drum brake
Brake drum diameter: 710 mm
Rated braking torque: 8000 Nm
Operation: Normally closed, spring applied, electromagnetic released
Feature: High torque, fail‑safe design
Working Principle
Power off / power failure:Heavy‑duty built-in springs press brake shoes firmly against the drum, providing high braking torque.
Power on:Electromagnetic actuator lifts the brake mechanism to release the brake.
Fail‑safe: Automatically locks when power is lost, ensuring equipment safety.
