The following are some common faults and summaries of European wire rope electric hoists:

1、 Electrical system malfunction

Power failure:

Performance: The electric hoist cannot start or operates unstably.

Reason: The power supply is not connected, the voltage is too low, or the power cord connection is poor.

Solution: Check if the power is connected, use a voltmeter to check if the power voltage meets the requirements, and ensure that the power cord is well connected.

Control switch malfunction:

Performance: The operation switch has no response or the action direction is incorrect.

Reason: The control switch is damaged or has poor contact.

Solution: Check the control switch and replace or repair it promptly if necessary.

Motor malfunction:

Performance: The motor cannot start, operates with difficulty, or has abnormal speed.

Reasons: Motor burnout, severe chamber sweeping, aging and failure of single-phase motor capacitors, short circuit caused by winding insulation damage, etc.

Solution: By detecting the current and voltage of the motor, the motor status can be determined. If any abnormalities are found, the motor needs to be repaired or replaced. For single-phase motors, a multimeter can be used to measure the capacitance and replace it; Disassemble the motor and check the insulation status of the winding.

Poor contact of the circuit:

Performance: Poor electrical circuit contact can cause the control panel indicator light to not light up or the operation to malfunction.

Solution: Check if the circuit connection is secure and rewire if necessary.

Fuse blown:

Performance: The electrical system is not functioning properly.

Solution: Check if the fuse is intact. If it burns out, it needs to be replaced.

Controller malfunction:

Performance: Affects the normal operation of the electric hoist.

Solution: Check if the controller is working properly and repair or replace it if necessary.

2、 Mechanical system malfunction

Overloaded excessively:

Performance: Difficulty or inability to start the electric hoist.

Reason: The load exceeds the rated range.

Solution: Check if the load is within the rated range to ensure safe use.

Uneven load:

Performance: Unstable operation.

Reason: The load center point is not aligned with the center of the hoist.

Solution: Check if the load is evenly distributed and ensure that the center point of the load is aligned with the center of the hoist.

Rope entanglement or knotting:

Performance: Affects the smooth operation of electric hoists.

Solution: Check if the lifting rope is tangled or knotted, and tidy it up if necessary.

Mechanical component wear:

Performance: Unstable operation or abnormal noise.

Reason: Mechanical components such as reducers and bearings are severely worn.

Solution: Regularly check the wear and tear of the mechanical parts, and replace or repair them in a timely manner.

Uneven guide rail:

Performance: The electric hoist experiences jamming during the lifting process.

Solution: Check if the guide rail is flat and adjust it if necessary.

Lack of lubrication:

Performance: Increased friction of mechanical components leads to jamming or unstable operation.

Solution: Regularly lubricate and maintain mechanical components.

Foreign object blockage:

Performance: There are foreign objects blocking the device, causing it to get stuck.

Solution: Regularly check for foreign objects around the equipment and maintain a clean working environment.

3、 Wire rope related faults

Wear and tear of steel wire rope:

Performance: Decreased diameter of steel wire rope and severe surface wear.

Reason: Long term use, heavy load, or inclined suspension, etc.

Solution: Regularly check the wear of the steel wire rope and replace it if necessary. Avoid improper operations such as inclined lifting.

Deformation of steel wire rope:

Performance: The steel wire rope exhibits phenomena such as twisting, bending, or breaking.

Reason: Improper installation, impact or overload, etc.

Solution: Ensure that the steel wire rope is installed correctly to avoid impact and overload. If any deformation is found, it should be replaced in a timely manner.

Wire rope breakage:

Performance: The steel wire rope suddenly broke, causing the load to fall.

Reason: Severe wear of the steel wire rope, overload or impact, etc.

Solution: Regularly inspect the wear and breakage of the steel wire rope, and promptly replace the steel wire rope that meets the scrap standard. Avoid improper operations such as overload and impact.
