The C-rail routed parallel to the track carrier is an elegant way of directing current to the lifting gear and trolley. This involves suspending a rail with a cross section in the shape of a C to clamping arms, open at the bottom. Carriages with 4 rollers run in the C-rail, carrying a power supply cable. As standard, we have provided a line carriage every two metres which means that, when the cable is retracted, the cable hangs down approx. 1 metre from the C-rail. The maximum track length must not exceed 30 metres. C-rail length of 4 m, suspension every 2 m.
