(Not parent commenter) lil hedge makes it harder to argue! And more clear to me about experience/intuition vs. some specific dataset on hand.

Hope this comment doesn’t feel pushy - emphasis on my additions:

The lift is likely on a gimbal. If the wheels on one side of the lift are 1cm higher than the other, that would move the platform at the top by 8cm or something. If both guys are on one side of the platform that could be enough to make the whole thing tilt by another 1cm at the wheels, and so on.

From what I can tell, that lift is not designed to be operated on a plastic barge. So, ostensibly:

That dock is not designed to carry equipment, certainly not an elevated platform, and is not designed to be operated as a barge.
