YWZ5-710/B301 Series (Explosion-proof) are normally closed, explosion-protected electro-hydraulic drum brakes specially designed for hazardous areas with flammable gas, vapor or dust. They are widely used in explosion-proof hoisting, conveying, port and mining machinery.
Basic Identification
Model: YWZ5-710/B301 Series (Explosion-proof)
Type: Explosion-proof electro-hydraulic drum brake
Brake drum diameter: 710 mm
Actuator: Equipped with BEd301 series explosion-proof electro-hydraulic thruster
Function: Braking, stopping, load holding and emergency safety braking
Working Principle
Brake (power off):Heavy-duty built-in springs press the brake shoes against the drum, providing stable braking torque.
Release (power on):The explosion-proof electro-hydraulic thruster is energized to lift the brake arms and release the brake.
Fail-safe: Automatically brakes in case of power failure or emergency, ensuring safety in explosive environments.
