It wouldn't happen accidentally. I used to work at an old shop where we had air over hydraulic hoists with separate, floor mounted controls for each column, and with NO mechanical lock outs. Depending on the weight distribution, you to adjust the flow to each column to keep things going up or down in sync. Added to the difficulty of operating the hoist were the occasions where someone accidently nudged the floor control of one of the columns when they walked by. If that wasn't bad enough, one of the hoists had a slow hydraulic leak. You knew when it was low when it suddenly, without warning, dropped 8 to 10 inches. My stomach still churns now when I operate any hoist. I also still wake up in a cold sweat at night after yet another wayward hoist dream. Thank goodness not much terrible actually happened, though it got too darn close far too often for me to ever rest easy on this earth again.
