Why is there sparks on the sliding contact line of the bridge crane?

The seamless sliding contact line is generally used indoors for powering LDA single-beam cranes and double-beam bridge cranes because of its convenient use . Some customers have discovered that sparks may appear during use. The editor of our factory will introduce to you the cause of sparks in the sliding contact line of bridge cranes.

The sliding contact line is composed of two parts: the sliding line guide rail and the current collector. The problem of sparking on the sliding contact line is that there is a problem with the contact between the guide rail and the current collector. The analysis is as follows:

1.  Poor contact between the brush surface and the guide rail.
2.  Severe collector wear may also produce sparks.
3.  The quality of the sliding contact wire and the current collector is not good, which can also cause sparks. Inferior trolley wires and current collectors are prone to safety hazards, including trolley wire shells, conductor materials of trolley wires, and the percentage of carbon brush copper in the current collectors. If these are not qualified, they will cause serious safety hazards.

If you understand the cause of the spark, you must take corresponding measures. The solutions and prevention methods are as follows:

1.  When installing the sliding contact line and the current collector, check the rail joints, and properly run in the brushes, and ensure that the contact area between the current collector and the sliding contact line is 60%;
2.  Comply with the maintenance procedures for bridge cranes and regularly check the wear and tear of collectors;
3.  The use of good quality trolley wires can ensure the safety of the power supply of the crane. The editor of our factory recommends that you find a regular manufacturer to buy it.

During the use of the bridge crane, in order to ensure the normal use of the safe trolley line, the operator should pay attention to the operation specifications, the maintenance personnel should do regular maintenance and inspection , and the parts should be replaced in time if the parts are severely worn.
