YWZ4-710/180A Electro-hydraulic Drum Brakes

YWZ4-710/180A Electro-hydraulic drum brakes

The YWZ4-710/180A is a heavy-duty electro-hydraulic drum (block) brake, widely used as a working or parking brake for large-scale industrial machinery. It is driven by an electro-hydraulic thruster to achieve smooth, reliable, and high-frequency braking.

The model number breakdown is as follows:

YWZ4: The series designation for standard electro-hydraulic block brakes.

710: The Brake Wheel Diameter of 710 mm.

180: The Nominal Thrust Force of 1800 N (approx. 180 kgf) of the matched electro-hydraulic thruster.

A: Typically indicates a structural variant, such as a specific mounting dimension or an improved version of the standard model.

💡 Key Features & Characteristics

Heavy-Duty Performance:

Massive Braking Capacity: With a 710 mm brake wheel and an 1800 N thruster, this brake delivers exceptionally high braking torque, making it ideal for heavy-load machinery like large cranes and hoists.

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 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 YWZ4-710/180A 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.

📋 General Technical Specifications

表格

Note: The YWZ4-710/180A is a critical safety component. Always ensure that the equipment's foundation and shaft can withstand the reaction forces generated during emergency braking. Due to its massive size and braking power, regular inspection of the brake pads and hydraulic thruster is essential to maintain peak safety and performance.
