Towing trolley is the leading trolley in the festoon system and drags all the trailing trolleys with it. It has 8 bearings which gives it better stability and strength. The towing arm is inserted inside the towing trolley and moves with the hoist. The towing trolley is made of CRCA and is plated to prevent corrosion. Hooks are given in order to allow free rotation of the trolley thus preventing tangling of cables.
