Sudden interruption of hydraulic winch during operation may be caused by various factors such as hydraulic system, mechanical components, electrical control, load and pressure, environment and operation. The following are specific reasons and analysis:

1、 Hydraulic system issues

Insufficient hydraulic oil supply: Hydraulic pumps, filters, or pipelines are blocked, causing hydraulic oil to be unable to be smoothly supplied to the hydraulic motor, thereby causing the winch to stop running. In addition, low hydraulic oil levels or system leaks can also cause similar problems.

Hydraulic oil contamination: Contaminants such as dirt, debris, or moisture entering the hydraulic system may damage the hydraulic motor or block critical components, leading to the interruption of winch operation.

Hydraulic fluctuation: Improper pressure setting or pressure relief valve failure in the hydraulic system may cause hydraulic fluctuations, affecting the normal performance of the hydraulic motor and causing the winch to stop.

2、 Mechanical component failure

Internal malfunction of hydraulic motor: Damage or wear of internal mechanical components such as bearings and gears may cause the hydraulic motor to suddenly stop rotating, thereby interrupting the operation of the winch.

Damage to dynamic and static friction plates: In the clutch, the dynamic and static friction plates often separate and mesh, and are subjected to shear forces. The metal coating on the surface of the outer friction plate is prone to wear and fall off, resulting in unstable or no output torque, surface slippage, and ultimately causing the winch to stop running.

Damage to outer retaining ring: If the outer retaining ring of CLRUR A85 * 3 breaks or deforms, it may lose its axial positioning effect on the friction plate, causing the dynamic and static friction plates to not engage, the torque to not be output, and the winch to stop running.

3、 Electrical control system malfunction

Electrical connection issues: Loose electrical connections, damaged wires, or control equipment failures may cause the electrical control system of the hydraulic winch to fail, resulting in the winch stopping operation.

Control circuit failure: Short circuit, open circuit fault or diode breakdown in the control circuit may also cause interruption of winch operation.

4、 Load and pressure issues

Load exceeding rated capacity: If the load carried by the hydraulic winch exceeds its rated capacity, it may cause the winch to stop running to protect the equipment from damage.

Abnormal system pressure: The oil pressure drop or overpressure in the hydraulic system may trigger the safety protection mechanism of the winch, causing it to stop running.

5、 Environmental and operational factors

High ambient temperature: High temperature environments may cause hydraulic oil to overheat, leading to the interruption of winch operation.

Improper operation: If the operating handle is not placed in the zero position, the position of the starter toggle switch does not match the actual operation mode, etc., it may also cause the winch to fail to start normally or interrupt operation.
