YW630-1250 Electro-hydraulic Drum Brakes

 

💡 Key Features & Characteristics

Heavy-Duty Performance:

Massive Braking Capacity: With a 630 mm brake wheel and an exceptionally powerful 12500 N thruster, this brake delivers extremely high braking torque. It is specifically engineered for heavy-load, high-inertia machinery.

High Action Frequency: Capable of frequent braking operations, ensuring reliable performance in demanding, continuous-cycle applications.

Advanced Structural 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 eliminates the need for regular greasing during use.

Equal Clearance Mechanism: Features an interlocking equal clearance device that automatically keeps the clearance between the brake shoes and the wheel perfectly even on both sides. This prevents one side from dragging or rubbing against the brake wheel.

Easy Maintenance: The brake pads (linings) use a secure, quick-release inserted or clipped structure. They are typically made of non-asbestos materials, 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 usually provided on one side, allowing for convenient and precise adjustment of the braking force.

Robust Environmental Adaptability:

Designed to operate reliably in ambient temperatures ranging from -20°C to +50°C and in environments with up to 90% relative humidity.

Optional Safety Devices:

Can be equipped with optional limit switches for "brake open" status and "pad wear limit", providing interlock protection and fault signals to enhance operational safety.

🏭 Typical Applications

The YW630-1250 is essential for heavy machinery in demanding industrial environments:

Port & Harbor: Large ship-to-shore cranes, RMGs, and bulk material handling equipment.

Metallurgy & Steel Mills: Heavy overhead cranes, rolling mills, and other equipment requiring frequent and powerful braking.

Mining: Heavy-duty hoists, winches, and large inclined belt conveyors.

General Industry: Large-scale construction machinery, heavy valves, and rotating mechanical drives.
