Here are some solutions to the problem of poor contact of the sliding contact wire in electric hoists:

1、 Check and adjust the sliding contact line interface

Interface flatness:

Check if the interface of the sliding contact line is flat and ensure that there is no misalignment or deformation.

If the interface is found to be uneven, it should be reprocessed according to the joint process requirements to ensure that the interface is smooth and flat.

Interface reinforcement:

Reinforce the interface position of the sliding contact line to prevent loosening or deformation of the interface due to vibration or external forces during use.

2、 Check and replace the current collector

Collector model and status:

Check if the model of the current collector is suitable for the sliding contact wire being used, ensuring good coordination between the collector and the sliding contact wire.

Check if the rollers, springs, and other components of the current collector are severely worn. If they are severely worn, they should be replaced in a timely manner.

Adjustment of current collector:

Adjust the position of the current collector to ensure that it can make correct and stable contact with the sliding contact wire.

If the positioning of the collector is poor, the conductor roller should be replaced or other necessary adjustments should be made.

3、 Check and adjust the electrical system

Electrical connection:

Check if the electrical connection between the sliding contact wire and the collector is good, ensuring that there is no looseness or poor contact.

If poor electrical connections are found, they should be reconnected and the connecting bolts tightened.

Electrical parameters:

Check if the parameter settings of the electrical system are correct, such as current, voltage, etc.

If the electrical parameters are set improperly, they should be adjusted according to the actual situation.

4、 Improving environmental factors

Environmental temperature:

If the ambient temperature is too high, cooling measures should be taken, such as using insulation boards, sun visors, etc., to reduce the operating temperature of the sliding contact wire and current collector.

ambient humidity:

In humid environments, it is important to ensure that the electrical system is dry and has good insulation performance to prevent poor contact caused by moisture.

5、 Other precautions

Regular maintenance:

Regularly maintain the sliding contact wire and collector, including cleaning, lubrication, etc., to extend their service life.

Safe operation:

When using an electric hoist, safety operating procedures should be followed to avoid equipment damage or safety accidents caused by improper operation.
