Well, that's terrifying. No idea if it's hydraulic, traction, winding drum or what, but whichever it looks like a great way to reduce a human body to something akin to drywall compound.
I don't know what the safeguards are but litigation is different in Germany. Typically you have to take responsibility for your actions there, and if you take a risk knowing the danger the property owner is not liable.
My German relatives can't believe that a burglar can sue here for injury, or some of the frivolous law suits we have here. It just doesn't fly with practical Germans.
