When carrying out infrastructure construction, do not impact the safety skid line, and do not directly press heavy objects on the skid line. After the completion of construction, the garbage dust on the safety slide line should be removed immediately. During normal maintenance, the staff is not allowed to trample their feet on the sliding contact line or its support to prevent deformation and bending of the sliding contact line and accidents.
In particular, when the deviation of track overlap, gauge and inclination is large, the frequency of use is high, the workshop dust is too large, there is water, acid, alkali, fog, high temperature, high pressure and outdoor environment, daily maintenance and maintenance should be strengthened, and the maintenance time should be shortened as needed.
