Clearly posted on my freight lifts was a warning that under no circumstances should riders be allowed except for a trained operator if required like if the forklift driver had to move from floor to floor on the larger capacity lifts. Many of my lifts were pit-less with automatic fold down ramps. when the platform/ cr was all the way down there mighty be less than 3" clearance. One evening a maintenance worker thought it a good idea to inspect some of the safeties and cable connections underneath, so instead of raising the platform to a point where he could rotate the service locks in place for under body work and tag with his lock out clip he crawled under on his hands and knees this was a very large lift with a beam structure in the platform that was 12". while under there someone saw the platform not all the way down and pushed the down button and walked on by.
The guy knew he was trapped once the platform started down so he laid flat as he could between where he thought the beams would miss him. Unharmed but with no way to get out from under he managed to use his cell phone and call for help it was nearly an hour before he got hold of someone to get him out from under it
