Towing arms and Transition boxes
Towing Arms:
A towing arm is attached to the moving machinery and connected to the collector trolley via chains. The arrangement is such that when pulling in either direction one of the collector towing chains is taut, the other remaining slack. In this way lateral movements of the crane, hoist, etc. are not transmitted to the trolley. This tolerance provides ultimate security of service!
Transition boxes:
A transition box can be mounted on the towing arm or close by the apparatus/machine. This unit facilitates the connection of the flexible cable from the collector trolley with the fixed wiring from the apparatus/machine being fed.
- Note: The towing connector on the arm should be installed 10 - 30 mm lower than the towing connection on the trolley and should be aligned directly below the housing opening in the vertical plane.
