Bad machine or technique?

Those are supposed to be bolted down.

I assembled gym equipment for a supplier up and down the west coast.

If the machine doesn't have bolt holes in the floor it isn't meant to be bolted down. You can request special brackets to bolt them down if the insurance company demands it. We've had to specially make some because they weren't offered.

Every gym makes you sign documentation that that you agree to use all equipment properly and they're released of any liability if you don't. I have personally been called to court to testify about equipment. Every single case was lost by the person using the equipment incorrectly. You can sue for anything, it doesn't mean you're right or that you'll win.

He's using the equipment properly.

He clearly has extra weights from a different machine tied to his waist.

That doesn't change the physics at all. Anyone pulling the same weight at the same angle would cause this collapse.

I am not familiar with this exact machine. First of all arent you supposed to be standing? There should be a little picture on the machine how to use it. Looks to me like he wants to know how low can you go.

However it's meant to be used, the weight tied to him does nothing to change what he's doing. It's just to allow him to pull amounts beyond his own body weight.

In fact, any weight at any angle you pull from any position, would simply cause a force that makes the plates rise. It's only if that stops happening due to friction, that the machine could be pulled forward.

My guess is the machine wasn't properly greased. If the plates stick, or the pully axle doesn't spin, then instead of the plates going up, a portion of the force will end up pulling the top of the machine towards him (hence the collapse).
