The 2 pieces of winch brake disc spring work together during the crane braking process to ensure the stability and reliability of the braking system.
1. Composition of the braking system
Winch brake disc: usually composed of two brake discs, one for the main brake disc and one for the auxiliary brake disc.
Brake: including brake calipers, brake pads, pistons, return springs and other components.
Control system: usually includes hydraulic systems, pneumatic systems or electronic control systems to control the start and stop of the brake.
2. Working principle
Brake start: When the crane needs to brake, the control system will send a signal to drive the brake piston (or other drive device) to press the brake pads against the two winch brake discs.
Friction force generation: The brake pad contacts the brake disc, generating friction, which blocks the rotation of the winch through friction, thereby slowing down or stopping the movement of the crane.
3. Collaborative work of the two brake discs
Main brake disc: As the main brake disc, it bears the main braking force. The main brake disc is generally installed on the fixed part of the winch, opposite to the rotating part of the winch.
Auxiliary brake disc: As an auxiliary brake disc, it works with the main brake disc to provide additional braking force. The installation position and structure of the auxiliary brake disc are similar to those of the main brake disc, but the size and thickness may be different.
4. Specific coordination mechanism
Friction force distribution: The main brake disc and the auxiliary brake disc share the braking force through the compression of the brake pads. This distribution can ensure uniform braking force and reduce the wear and heat load of a single brake disc.
Heat load dispersion: Since the two brake discs work at the same time, the heat generated can be dispersed to the two discs to avoid failure of a single disc due to overheating.
Redundant design: If one of the brake discs or brake pads is damaged, the other brake disc can still provide a certain braking force, increasing the reliability of the system.
Dynamic balance: The coordinated work of the two brake discs can maintain the dynamic balance of the winch and reduce vibration and shaking caused by uneven braking force.
5. Braking process
Brake start:
The control system sends a braking signal, and the hydraulic or pneumatic system drives the piston.
The piston pushes the brake pads, pressing them against the main brake disc and the auxiliary brake disc at the same time.
Braking force generation:
The main brake disc and the auxiliary brake disc contact the brake pads, generating friction.
The friction hinders the rotation of the winch, slowing down or stopping the movement of the winch.
Brake release:
The control system sends a brake release signal, and the hydraulic or pneumatic system cancels the thrust of the piston.
The brake pads separate from the brake disc, and the winch resumes free rotation.
6. Maintenance and inspection
Regular inspection: Regularly check the wear of the brake disc and brake pads to ensure that their surfaces are flat and undamaged.
Cleaning and maintenance: Keep the brake disc and brake pads clean to avoid oil and impurities that affect friction.
Replacement of parts: When the brake disc or brake pad is severely worn, replace it in time to ensure the performance and safety of the braking system.
The 2 pieces of winch brake disc spring work together during the crane braking process to ensure the stability and reliability of the crane's braking system by evenly distributing the braking force, dispersing the heat load, providing redundant design and maintaining dynamic balance. This collaborative mechanism not only improves the braking efficiency, but also extends the service life of the braking system. Regular maintenance and inspection are important measures to ensure the proper functioning of the brake system.
