Support for flexible cable supplying trolley on rails - has cable doubling back on itself, being supported on two groups of carriages running on parallel tracks

摘要

The cable supplies a trolley running on a loading bascule bridge. When the trolley moves, the cable moves on a following carriage to which it is attached. The cable carriages run on two tracks parallel to the trolley direction of movement. The cable starts from a fixed point between the hinges of the loading bascule bridge, and runs in a first direction away from the hinge on first group of cable carriages on the first track. The cable doubles back in the other direction on a second group of carriages on the second track, to the trolley.
