Sliding contact line current collector is the main device on the current collection side of the sliding contact line system that picks up electrical energy. It directly conducts electrical energy to the electrical appliance through the sliding contact between the collector brush and the guide rail, thereby achieving mobile power supply for the system. The sliding contact line current collector consists of two parts: a mechanical tension device and a collector brush that directly slides in contact with the guide rail. Sliding contact line current collectors, current receivers, power supply devices, and current conductors. Multi-pole sliding contact line current collectors, single-pole sliding contact line current collectors, single-pole row-type sliding contact line current collectors, and combined sliding line current collectors.
As a key component of crane power supply, how to select a safe sliding contact line current collector is particularly important. Here is a brief introduction to the selection of safe sliding contact line current collectors. Safe sliding contact line current collectors mainly consist of shoe pieces, shoe boxes, springs, current collector brackets, and current collector support parts. Current collectors are divided into heavy-duty and light-duty types. The choice between light-duty and heavy-duty current collectors is determined by the current of the sliding contact line. Generally, if the sliding contact line current is less than or equal to 500A, a light-duty current collector can be selected; if it is greater than 500A, a heavy-duty current collector should be selected.
When selecting a safe sliding contact line current collector, consider a manufacturer that matches the sliding contact line. Do not use current collectors indiscriminately, otherwise it will affect the normal operation of the crane, and in severe cases, it may burn out the sliding contact line. The shoe pieces on the current collector are made of copper-containing carbon-based material pressed together. After purchase, check the fit with the sliding line. Since the current collector itself is a consumable item, long-term use will wear out the shoe pieces, so it is necessary to regularly check the wear level of the shoe pieces on the current collector and replace them periodically.
