The present invention relates to a trolley jack (1; 101; 201) comprising a main body (2; 102; 202) and a lifting element (3; 103; 303) capable of moving up or down for lifting a heavy object, and a lever assembly (4; 104; 204) projecting upwards along a longitudinal axis (5; 105; 205) for allowing a user to manually push and move the jack (1; 101; 201), where a lower end (4c; 104c; 204c) of the lever assembly (4; 104; 204) is connected in an articulated manner to the main body (2; 102; 202) according to a transverse axis of rotation (8; 108 208), the lever assembly (4; 104; 204) being capable of being lowered with respect to said transverse axis of rotation (8; 108; 208) and arranged against the main body (2; 102; 202). Providing a hinged lever assembly increases jack storage and transport possibilities. |
