This balloon air cushion jack has a load capacity of 3 tons. Simply plug 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 from slipping jacks. The jack can be placed under all 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 the vehicle can be lifted to make two wheels accessible at once. It lifts cars, trailers, caravans, etc. The hose length is 4.5 m.
