Mounting the trolley towing arm

The trolley towing arm is installed above the hoist panel. It pulls the electrical cables for the trolley power supply (festoon cable system or energy chain) and the cross-type limit switch of the trolley travel limit switch back and forth parallel to the trolley.

The trolley towing arm must be installed differently, depending on the main girder (I-beam or box girder) and the type of power supply (festoon cable system or energy chain).
