YWZ5-710/B201 Series(Explosion-proof) Electro-hydraulic Drum Brakes

YWZ5-710/B201 series (explosion-proof) are normally‑closed, spring‑applied, electro‑hydraulically released industrial drum brakes with explosion‑protected construction, intended for safe braking, stopping and load holding in explosive gas or dust hazardous environments.

Basic Identification

Model: YWZ5-710/B201 Series (Explosion-proof)

Type: Explosion‑proof electro‑hydraulic drum brake

Operation: Normally closed • Spring applied • Electro‑hydraulically released

Brake drum diameter: 710 mm

Actuator: Matching explosion‑proof electro‑hydraulic thruster

Working Principle

De-energized: Built‑in springs press brake shoes against the drum to provide braking.

Energized: Explosion‑proof electro‑hydraulic thruster actuates to release the brake.

Fail‑safe: Automatically applies braking upon power failure or emergency stop.
