This balloon air cushion jack has a load capacity of 3 tons. Simply insert it into the exhaust, and the exhaust gases will inflate the air cushion jack through the running engine at idle. A check valve prevents it from sinking, ensuring no injuries occur from slipping jacks. The jack can be placed under any load-bearing parts, such as in the center, on the side, or at the axle. It is ideal for changing tires and mounting snow chains, as it can lift the vehicle in a way that allows access to two wheels at once. It lifts cars, trailers, caravans, etc. The hose length is 4.5 meters.
