SWZ Series Manual Brake1

1. Main Structure and Working Principle

- Structural Components: Typically, it consists of a brake wheel, brake arm, friction pads, manual operating lever (or handwheel), spring mechanism, etc.
- Working Principle: By pulling the manual lever or rotating the handwheel to apply force, the mechanical linkage mechanism (such as levers and cams) presses the friction pads against the brake wheel, generating frictional force to achieve braking. When released, the spring returns to its original position to release the brake.

2. Typical Features

- Manual Control: No need for electricity or air supply, relying on manual operation, suitable for emergency situations during power outages or maintenance at fixed locations.
- Self-locking Function: Some models are equipped with self-locking mechanisms, maintaining the braking state without the need for continuous force application.
- Wear-resistant Materials: Friction plates often use asbestos, ceramic, or metal sintered materials, which are resistant to high temperatures and wear.
- Adjustability: The braking force and stroke can be adjusted by regulating bolts or spring preload.

3. Common Application Scenarios
- Safety braking for cranes and hoists.
- Shutdown positioning for belt conveyors.
- Emergency stop for rotating parts of machine tools.
- Safety locking during maintenance of wind power equipment.

4. Key Points for Installation and Maintenance

- Installation: Ensure that the brake wheel and friction plate are centered with uniform clearance (typically 0.5-1mm); reserve sufficient movement space for the manual operating lever.
- Commissioning: Adjust the spring force to match the braking force with the load requirements, avoiding being too tight (difficult to operate) or too loose (slippage).
- Maintenance:
- Regularly check the thickness of the friction plate (replace when worn to 1/3 of the original thickness).
- Clean oil and dust from the brake wheel to prevent a decrease in friction.
- Lubricate moving parts (such as hinges and bearings), but avoid contaminating the friction surface.

5. Precautions
- Safe Operation: The brake is only to be used as an auxiliary or emergency device and should not replace the main braking system.
- Regular Testing: When not in use for a long time, manually test the braking effect to prevent the mechanism from getting stuck.
- Environmental Adaptability: Avoid using in damp or corrosive environments, or choose models with a higher protection rating (such as IP54).

6. Troubleshooting
- Brake Failure: Check for worn friction pads, broken springs, or loose adjusting screws.
- Operation Jamming: Clean and lubricate the linkage mechanism and check for any deformation.
- Abnormal Heating: May be caused by wobbling of the brake wheel or uneven contact of the friction pads. Re-calibration is required.
