Sudden interruption during the operation of a hydraulic hoist may be caused by various factors such as power supply, hydraulic system, solenoid valve, mechanical component failure, or improper operation. The following is a specific analysis:

Power supply issue: Unstable power supply or sudden power outage can cause the hydraulic hoist to be unable to rise and fall, and in severe cases, it can even cause equipment circuit burnout or motor failure.

Hydraulic system issues:

Insufficient hydraulic oil or oil quality issues: Insufficient hydraulic oil can lead to insufficient system pressure, preventing the hydraulic hoist from working properly. Meanwhile, if hydraulic oil is contaminated or deteriorated, it can also affect the normal operation of the system.

Hydraulic system leakage: The aging or damage of seals in the hydraulic system can cause hydraulic oil leakage, thereby reducing system pressure and preventing the hydraulic hoist from working properly.

Hydraulic system blockage: Blockage in the oil circuit or filter of the hydraulic system can affect the flow of hydraulic oil, resulting in slow or immovable lifting speed of the hydraulic hoist.

Mixing air into the hydraulic system: Mixing air into the hydraulic system can cause unstable oil pressure, affecting the normal operation of the hydraulic hoist.

Electromagnetic valve failure: The solenoid valve is an important component in the hydraulic system. If the solenoid valve coil is burned out, the solenoid valve is stuck, or the solenoid valve is installed in the wrong direction, it will cause the hydraulic hoist to malfunction. For example, reverse installation of the solenoid valve coil may cause the solenoid valve to discharge oil into the tank, resulting in abnormal system pressure.

Mechanical component failure: If the mechanical components of a hydraulic hoist, such as hydraulic cylinders, pistons, directional valve cores, etc., wear or get stuck, it can also cause the hydraulic hoist to malfunction. For example, if the hydraulic cylinder piston gets stuck, it will cause the hydraulic hoist to not move up and down.

Improper operation: Improper operation during the operation of the hydraulic hoist, such as failure to start, stop or adjust according to the operating procedures, may also cause the hydraulic hoist to suddenly stop running.
