The invention discloses an automatic lifting device for a general chassis, and relates to the technical field of auxiliary devices for army general chassis overhauling. The automatic lifting device comprises at least one hydraulic lifter, a control loop used for controlling the hydraulic lifter to lift and manual fine adjustment loops, wherein each manual fine adjustment loop is matched with the corresponding hydraulic lifter. The control loop comprises a motor, a hydraulic pump and a first manual reversing valve. The motor is used for driving the hydraulic pump to rotate. An oil inlet of the first manual reversing valve is connected with an oil outlet of the hydraulic pump through a pipeline. An overflow valve is installed between the first manual reversing valve and the hydraulic pump. An oil port of each hydraulic lifter is provided with a synchronizing pump in a matched manner. An oil port of each synchronizing pump is in butt joint with an oil port of the corresponding first manual reversing valve. Oil is supplied to the multiple hydraulic lifters through the synchronizing pumps, and synchronous jacking and synchronous descending are achieved. One person can quickly complete jacking of the general chassis, the operation time is shortened, and therefore the emergency maintenance during wartime is facilitated.
