Sudden interruption of operation of electric winches may be caused by various reasons such as power failure, motor problems, abnormal control circuits, overload protection triggering, operational control errors, mechanical failure jamming, brake device intervention, or environmental interference. The following is a detailed summary of these reasons:

1、 Power and motor issues

Power failure:

Power outage, phase failure (three-phase motor phase loss causing inability to start or interruption of operation), low or high voltage may all affect the normal operation of the winch.

The grounding of the power line or the action of the grounding protection device can cause a power outage and also cause the winch to stop running.

Motor malfunction:

Motor burning or damage, such as winding short circuit, open circuit or insulation aging, can cause the motor to lose its working ability.

Motor overload operation may cause overheating, which may trigger the protective device to stop the winch from running.

2、 Control circuit and component issues

Control circuit fault:

The control circuit is open or short circuited, causing the signal to be unable to be transmitted to the motor or starter.

Damaged components such as diodes and relays in the control circuit affect the transmission of control signals.

Malfunction of operating components:

The stop button is not reset or damaged, resulting in continuous circuit disconnection.

Internal faults in the starter, such as damaged contactor coils, fuses, or wiring terminals, can cause control circuit failure.

Operation cable breakage or loose joints result in the inability to transmit the start signal.

3、 Overload and protection device

Overload operation:

When the winch operates beyond its rated load, it may cause the motor to overheat or the protective device to actuate, causing the winch to stop running.

Protective device action:

The failure of the thermal relay to reset or the melting of the fuse may be caused by overload or short circuit, resulting in the winch stopping operation.

The action of other protective devices (such as overcurrent protection, undervoltage protection, etc.) may also cause the winch to stop running.

4、 Operation and control issues

Operational error:

The operator accidentally operated the button or controller, causing the winch to stop running or run in the wrong direction.

Improper setting of the remote control or controller, such as setting it to one-way operation mode, results in the winch only being able to operate in one direction.

Control signal issue:

The transmission of control signals is obstructed or interfered with, such as weak or interfered wireless remote control signals, causing the winch to be unable to receive the correct control signals.

5、 Mechanical failure and jamming

Mechanical component damage:

The wear or damage of mechanical components such as gears and bearings inside the winch can cause interruption or inability to start the winch.

The steel wire rope is severely worn and may break or detach, causing the winch to lose traction.

Jamming phenomenon:

The winch encounters obstacles or blockages during operation, causing it to be unable to continue running.

The steel wire rope inside the drum is tangled or the tail wheel and guide wheel are stuck or tangled, which affects the normal operation of the winch.

6、 Other factors

Environmental factors:

The operating environment of the winch is harsh, such as high temperature, humidity, corrosion, etc., which may affect the normal operation and service life of the winch.

The winch is subjected to external impact or vibration, resulting in loose or damaged components.

Improper maintenance and upkeep:

The long-term lack of maintenance and upkeep of the winch has led to increased component wear or frequent malfunctions.

Poor lubrication or deterioration of grease can cause increased resistance or component damage during winch operation.
