Slewing Power Supply Slide Contact Line For Tower Crane, 35 Mm² Busbar
The busbar for tower crane slewing power supply 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.
