💡 Key Features & Characteristics
Manual Hydraulic Operation:
Foot-Pedal Control: The brake is actuated by a foot-operated hydraulic pump. This allows the operator to manually modulate the braking force, providing a highly smooth and precise method for slowing down or stopping machinery.
Normally Open Design: It is a "normally open" brake, meaning it remains in the released (unbraked) state by default. Braking force is only applied when the operator actively presses the foot pedal.
No Power Supply Required: Because it relies entirely on manual hydraulic pressure, this brake operates completely independently of any electrical or pneumatic power sources.
High-Performance Specifications (TYWZ2-315):
Braking Torque: Delivers a controllable braking torque in the range of 0 to 400 N·m, depending on the pressure applied by the operator.
Brake Wheel Diameter: Designed for a standard 315 mm brake wheel.
Physical Dimensions: Key installation dimensions include a height (H) of 610 mm and a base width (A) of 390 mm.
Unit Weight: Approximately 60 kg.
Robust & Maintenance-Friendly Design:
Self-Lubricating Bearings: The main pivot points are equipped with self-lubricating bearings, which ensure high transmission efficiency, a long service life, and eliminate the need for regular greasing.
Equal Clearance Mechanism: Features an interlocking device that automatically keeps the clearance between the brake shoes and the wheel perfectly even on both sides, preventing uneven wear or dragging.
Easy Maintenance: The brake pads (linings) use a secure, quick-release clip-on structure, making replacement fast, convenient, and safe.
Environmental Adaptability:
Designed to operate reliably in ambient temperatures ranging from -20°C to +50°C and in environments with relative humidity up to 90%. (Note: Corrosion-resistant versions should be used if the environment contains flammable, explosive, or corrosive gases).
🏭 Typical Applications
The TYWZ2-315 is ideal for applications where an operator needs direct, manual control over the stopping process:
Cranes & Hoists: Widely used for the travel (long travel) mechanisms of medium and small-sized overhead cranes, gantry cranes, and portal cranes to ensure smooth, jerk-free stopping.
Winches &绞车: Perfect for non-lifting winch drive mechanisms where controlled deceleration is required.
General Industrial Drives: Any machinery requiring a reliable, manually controlled fail-safe or operational brake without the need for external power.

Note: The TYWZ2-315 excels in providing smooth, operator-controlled braking. Because it is a "normally open" brake, it is primarily used for operational deceleration rather than automatic fail-safe parking. Regular inspection of the hydraulic lines for leaks and the thickness of the brake linings is essential to maintain optimal performance and safety.
