Air bladder jacks

Air bladder jacks

— jacks in the form of soft inflatable cylinders, usually connected to a car compressor or even an exhaust system. When deflated, the cylinder can be pushed into a very narrow gap, and due to the large footprint, such jacks are effective even in mud, soft sand, etc. On the other hand, the stability of such structures is low, and sharp objects (including individual parts of the bottom) pose a serious danger to them.
