Before using the brake, it is necessary to check whether each part is normal, and it is often inconvenient to operate. We analyzed the following fatal problems that directly cause inconvenience:
1. Insufficient lubricating oil in the brake causes the friction of the brake to increase and the brake is not sensitive.
2. The oil return valve is not well-sealed, and the tension spring of the oil outlet valve is broken, causing the elasticity of the slewing ring to decrease and inflexibility.
3. The brake cylinder cup is aging, swollen, and the piston is stuck, resulting in inflexible braking effect.
4. Brake shoe, brake gap is too large, resulting in insensitive operation.
5. The braking effect caused by the brake drum is not sensitive.
6. The brake hydraulic system enters the air, causing the hydraulic system to be insufficient.
7. The braking effect caused by brake wear is not sensitive.
