Holy fuck dude. How was the trolley still there... Fixed by only one bolt that wasnt even threaded through... My blood ran cold.

The bolt serves another purpose and the result is the cable not in the pulley, but on it's axle 😅

Ok i see, those cables are still pretty heavy though esp with the hook. I dont want to imagine being on site and seing that cable snap while moving formwork or a concrete bucket

Yes they are, I think you have to lower the crane - if not disassemble the pulley on the ground to put it back together, but first inspect how many wires broke (cable fraying). Then determine if the cable needs to be replaced or not (depending on how heavy you lift and % of the broken wires) replacing also doesn't come cheap, since it's a really long cable.

This is what the trolley looks like from below

Because it's being held in by the riveted or welded axel that goes through the bushing/bearing inside the center of the pulley wheel, you can see the axel bolt head a couple times in the video. That bolt at the top just keeps the top of the frame in shape.

  • At roughly 39-41 seconds, you can see the axel/bushing between the pulley and fixed rivet head on the outside of the frame, slightly popping out.
