YW-E Two-step Series Electro-hydraulic Drum Brakes: Installation Methods & Matching Accessories

YW-E Two-step Series Electro-hydraulic drum brakes

YW-E two-step electro-hydraulic drum brakes are vertically installed as standard with horizontal mounting optional, matched with ED series thrusters and exclusive damping cylinder assemblies for adjustable 1–15s two-stage delay braking. Standard accessories contain manual release lever and status limit switches; clamped quick-replace friction linings and sealing kits are regular wearing spares. Flameproof assemblies, custom brackets and dust shields are available optional parts for various harsh working conditions.

1. Installation Methods

Standard Vertical Installation

1. Fix the cast brake base firmly to a flat rigid foundation with high-strength bolts; keep the two brake shoes symmetrically wrapped around the outer surface of the brake drum.
2. Install the matched ED series electro-hydraulic thruster vertically upward to guarantee sufficient internal hydraulic oil lubrication and stable two-stage delay braking performance.
3. The built-in interlinked equal-gap balancing device automatically maintains uniform clearance between friction linings and the drum on both sides after installation, eliminating one-side dragging without frequent manual calibration.
4. Reserve ample surrounding space for friction pad replacement, two-stage torque adjustment, damping cylinder maintenance and manual release operation.

Optional Horizontal Side Mounting

Core Installation Requirements

• All hinge joints are equipped with maintenance-free self-lubricating bearings, no regular grease filling needed after installation.
• Clean all oil, dust and rust on the brake drum surface before commissioning to avoid reduced friction efficiency.
• Adjust the one-way throttle valve on the damping cylinder circuit after installation to set the two-stage delay time (adjustable range: 1–15 seconds) according to working conditions.

2. Standard Matching Accessories

Core Functional Components

1. ED Series Electro-hydraulic Thruster

    

   Special matched drive unit conforming to DIN15430, including ED23/5, ED30/5, ED50/6, ED80/6 for different YW-E models; controls brake opening and spring-applied fail-safe braking after power loss. Flameproof BEd series thrusters are supplied for explosive hazardous areas.

2. Damping Cylinder Assembly with One-way Speed Control Valve

    

   Exclusive two-stage braking accessory, used to adjust the time interval between first-stage soft deceleration torque and second-stage full holding/wind-proof torque (1–15s adjustable).

3. Manual Release Lever

    

   For emergency brake release during power failure, overhaul or static equipment maintenance.

4. Brake Status Limit Switches

    

   Feed back brake open/closed signals to the control system for electrical interlock protection; wear limit switches are optional to monitor friction pad abrasion threshold.

Consumable Spare Parts

1. Clamped Quick-replace Friction Linings

    

   Integrated molded non-asbestos wear-resistant pads; plug-in design allows fast replacement without disassembling the whole brake frame.

2. Two-stage Adjustment Hardware Kit

    

   Including primary deceleration spring, secondary holding spring, torque adjusting nuts, clearance adjusting screws and all fastening bolts for torque calibration.

3. Damping Cylinder Sealing Kits

    

   Replacement oil seals and gaskets to prevent hydraulic oil leakage of the delay braking module.

3. Optional Custom Accessories

1. Flameproof supporting parts (BEd thrusters, explosion-proof limit switches) for coal mines, chemical plants and other Ex hazardous zones.
2. Custom transition mounting brackets for horizontal installation or special narrow-space layout.
3. Heavy-duty dust protective covers for cement plants, mines and outdoor dusty cranes.
4. Anti-corrosion coated brake frames and linings for coastal damp, rainy or corrosive working environments.
5. Buffering assemblies to reduce impact and vibration during two-stage switching braking.
