YW-L500/E80 Series is a normally‑closed, electro‑hydraulically released industrial drum brake with optimized lever structure, designed for hoisting, conveying, crane and metallurgical machinery.
Basic Identification
Model: YW-L500/E80 Series
Type: Electro‑hydraulic drum brake
Brake drum diameter: 500 mm
Matching thruster: E80 series electro‑hydraulic thruster
Operation: Normally closed, spring applied, electro‑hydraulically released
Working Principle
Power off / power failure:Built‑in strong springs press brake shoes against the drum to achieve braking and holding.
Power on:Electro‑hydraulic thruster lifts the lever mechanism to release the brake.
Fail‑safe safety design.
