What are common problems of safety trolley line and how to solve them?
First, the safety trolley line is out of power. The reason is that electric brush climbs in the conductor, the brush wears seriously, conductor joint is not smooth, single connector is used, rail joint becomes loose. The correct way is to check whether the brush wears seriously, change electric brush, adjust the connecting joint, and adopt double-brush connector.
Second, the guiding rail is deformation, the collector doesn’t work. The main reason is the temperature is too high, the distance between lifting racks is too long or loose. It is useful to adopt anti-heat plate partially, add sun shield outdoors, increase the number of trolley line lifting racks, correct the conductor and screw down the screws.
Third, the trolley line shakes seriously, and for this problem, the reason is that fork can’t absorb the transmission error, guiding-rail has poor straightness, and lifting rack is loose. The right way is to modify tractor, adjust the straightness of guiding-rail, and tighten the screw mounts.
