Abstract
The pneumatic trolley jack (1) has folding suspension actuated on lifting the load. This includes flexible roller elements (5) of rubber or synthetic material. On each side frame (4) there are supports for the suspension. The roller elements are mounted in the cheek end of an arm (6) pivoted at its other end. An opening allows entry of a vertical stay (8) pressing on a bracket (9) on the frame. On this stay is a suspension spring (10). A movable stop gives tension adjustment of the spring.
