1. Hydraulic system problems: The bumper of the cone crusher is usually controlled by the hydraulic system. If there is a failure in the hydraulic system, such as a damaged hydraulic pump, a leaking hydraulic cylinder, or a clogged hydraulic valve, it may cause the bumper to fail to lift.
 

2. Electrical system problems: The control system of the cone crusher may depend on the electrical system. If electrical components such as switches, sensors or controllers malfunction, it may affect the normal operation of the bumper.

3. Mechanical structure problems: There may be problems with the bumper's mechanical structure, such as loose, broken or worn connectors, which may hinder the lifting action.

4. Improper operation: The operator may not follow the correct steps or methods during the operation, causing the bumper to fail to lift.
