The trolley towing arm pulls the trolley power supply (energy chain or festoon cable system) parallel to the trolley to the left and right. It is installed on the same side as the trolley power supply.
This section only applies if a trolley of construction D, DA, Z or ZA is connected to an overhead travelling crane with an energy chain.
The component parts of the trolley towing arm are enclosed loose and must be assembled.

Marking |
|
Attach the installed trolley
towing arm to the end carriages.
In most cases, the end carriage has a marking at which the trolley towing arm is to be attached. The switching point of the trolley travel limit switch is already adjusted for this position and the cable lengths correspondingly adapted.
Screw the trolley towing arm
tightly with the threaded bracket and rib nuts (2x).
