YW-L400/E50 Electro-Hydraulic Drum Brake

 

 

💡 Key Features & Characteristics

Compact & Space-Saving Design:

Space Optimization: The YW-L series is specifically designed to fit into tighter installation spaces compared to traditional drum brake models, making it highly versatile for complex machinery layouts.

Standard Compliance: Its connection dimensions and installation sizes comply with international and national standards, including DIN15435 and JB/T7021-2006.

High-Performance Specifications:

Braking Torque: The YW-L400/E50 model delivers a powerful nominal braking torque of 750 N·m.

Drive Unit: Powered by an Ed50/6 electro-hydraulic thruster, providing a reliable thrust force of 500 N.

Reliable & Maintenance-Friendly Design:

Self-Lubricating Bearings: The main swing hinge points are equipped with self-lubricating bearings. This ensures high transmission efficiency, a long service life, and completely eliminates the need for regular lubrication during operation.

Equal Clearance Mechanism: Features an interlocking equal clearance device that automatically keeps the clearance (退距) between the brake shoes and the wheel perfectly even on both sides. This prevents one side from dragging or floating against the brake wheel, ensuring smooth and balanced braking.

Easy Maintenance: The brake pads (linings) use a secure, quick-release clip-on (card-mounted) structure. They are available in various materials, including non-asbestos semi-metallic (hard/semi-hard) and soft linings, making replacement fast, convenient, and environmentally friendly.

Intuitive Adjustment: The main brake spring is housed inside a spring tube, and a braking torque scale is provided on one side, allowing for easy reading and precise adjustment of the braking force.

Optional Safety & Control Devices:

Can be equipped with optional add-ons such as manual release devices, limit switches (for open/closed status), automatic wear compensation devices, and delay valves for delayed closing.

🏭 Typical Applications

The YW-L400/E50 is widely used for the deceleration and parking (holding) braking of various mechanical mechanisms in demanding environments:

Lifting & Transport: Heavy-duty overhead cranes, gantry cranes, and material handling equipment.

Port & Harbor: Port loading/unloading machinery and bulk material handling systems.

Metallurgy & Mining: Steel mill equipment, mining machinery, and other heavy industrial drives.

Construction Machinery: Various large-scale engineering and construction equipment.
