Safety trolley line (electrical sliding contact line OR slide wire) is a new overhead crane mobile power supply device, insulation, safety, temperature resistance, vibration resistance, save energy, etc. The safe trolley line electric current carrier is smooth flat T2 copper bars or aluminum bars with wear-resistant conductor which are embedded in engineering plastic tubes or slot plate. There is opening at lower conduit for electric collector convenient operation, and the collector high wear-resistant copper-based graphite brushes will directly guide the electric power to the working electric appliance.
Overhead Crane will be frequent power off, and sometimes sparks in the electric transmission duct, seriously maybe explosion sound on safety trolley line, that maybe cause the collector often to replace, affect the production. so, we need the following improvements:
1. Increase the collector brush chamfer, and polished smooth
2. Increase the collector two corresponding brushes spring strength, flexibility, to ensure spring working
3. Strengthen the spring seat of the collector, to ensure the electric brush spring not to shift
4. There should be chamfer on the two pieces of safety trolley wire connection block, to ensure collector smooth transition. At the same time, in order to ensure the safety slide wire normal working, it is also necessary to standard operate, regular maintain, regular inspect.
