YW-E400/E50 Two-step Series are two-step adjustable, normally‑closed electro‑hydraulic drum brakes with dual braking torque levels, designed for smooth, controlled deceleration in hoisting, lifting and conveying machinery.
Basic Identification
Model: YW-E400/E50 Two-step Series
Type: Two-step electro‑hydraulic drum brake
Brake drum diameter: 400 mm
Actuator: Matched with E50 series electro‑hydraulic thruster
Operation: Normally closed, spring applied, electro‑hydraulically released
Feature: Two-step braking torque / two-stage braking action
Working Principle
The brake provides two levels of braking force (gentle braking + full braking) through dual-control or dual-thrust action.
Power off: Springs apply full braking for safety holding.
Power on: Electro-hydraulic thruster releases the brake according to control signal.
Two-step function realizes soft, shock-free deceleration to protect transmission system and load.
Key Features
Two-step / two-stage braking for smooth deceleration

Asbestos-free high-performance friction linings
Adjustable braking clearance and torque
Suitable for frequent heavy-duty operation
Easy installation and maintenance
Typical Applications
Cranes, hoists, winches
Elevators and lifting mechanisms
Conveyors requiring smooth braking
Metallurgical, port and mining machinery
Short version
YW-E400/E50 two-step series electro‑hydraulic drum brakes are dual‑action industrial brakes with 400 mm drum diameter, providing two-stage smooth braking for cranes and hoisting equipment.
