Sliding Contact Line Collector Carbon Brush (Brush Piece)

Recently, some customers have reported that the carbon brush on the collector of the safety sliding contact line wears out relatively quickly, roughly requiring replacement once a month on average. Yangzhou Dary Co., Ltd. believes that this is actually impossible. In many cases, it is because there are problems with the installation of the safety sliding contact line for cranes. Next, let's check a few aspects. Regarding the reasons for the rapid wear of the carbon brush on the safety sliding contact line collector, first of all, we should pay attention to the fact that when installing the collector bracket, the distance between the centerline of the collector bracket and the lower plane of the crane sliding contact line is not appropriate. At this time, to a large extent, this directly leads to excessive wear of the carbon brush. Moreover, for single-pole sliding contact lines, attention should also be paid to a certain distance between the centerline of the light collector bracket and the lower plane of the sliding contact line.

In detail, the height should be maintained at 157MM. Next, Yangzhou Tianxiang Electric Co., Ltd. reminds users that for the height between the centerline of the heavy collector bracket and the lower plane of the crane sliding contact line, it should be maintained at approximately 182MM.

Furthermore, the rapid wear of the carbon brush on the safety sliding contact line collector is also due to the pressure issue of the collector spring. If the pressure is relatively high, it will, to a large extent, lead to excessive wear of the carbon brush. Generally speaking, the contact pressure between the light collector and the sliding contact line is 25—28 Newtons.
