How to properly maintain and repair crane slip rings
Thread Content
According to professionals, the sliding contact wire inside a crane relies on the current flowing through the aluminum profiles; this current is transmitted outward through friction between the stainless steel and the conductive elements； It effectively ensures the proper operation of the entire lifting machinery. To this end, it is necessary to maintain the sliding contact wire in daily use. I. In accordance with relevant regulations, the brushes in the sliding contact line generally need to be inspected once every 1–3 months. During the inspection, special attention should be paid to assessing the degree of damage to the electrical brushes. If the wear amount is greater than 5 millimeters, experts recommend that we replace it. In addition, it is also necessary to check whether the relevant firmware is loose; if so, it should be tightened promptly. II. The connection wires within the sliding contact line should be inspected at least once a year to check for any signs of corrosion, displacement, or other issues in the bolts and welds. Make accurate records of information registration. III. Attention must also be paid to the construction environment of the crane; if there is a high level of corrosive gases in the vicinity, special attention should be given to components such as brackets, suspension clamps, and pullers. Furthermore, during inspections, workers must not step on power transmission pipes and supports, etc ； Prevent slips caused by imbalance.
