Product Description

35 Mm² Circular Arc Rail Bus Bar For Tower Crane Slewing Power Supply

The Circular Arc Rail Busbar is a new type of power supply device, which is connected with the collector by the cable and provides the tower crane with uninterrupted power supply through the closed-loop slewing busbar, so as to avoid the phenomenon that the cable is often twisted and broken when the tower crane is operating. It has the function of taking power from the original tower crane slip ring.
