The invention discloses a manual lifting platform which comprises a four wheel trolley frame. A pair of sliding rails are arranged on the two sides of the trolley frame in parallel, a support connected through a pair of X-shaped center shafts is mounted upwards in the sliding rails, pin shafts are connected between the two front feet of the support and the front ends of the sliding rails of the trolley frame respectively, sliding wheels are connected between the two rear feet of the support and the rear ends of the sliding rails of the trolley frame respectively in a rolling mode, a fixing shaft is connected between the two sliding wheels, a screw hole block is mounted in the middle of the fixing shaft, a screw rod is screwed in the screw hole of the screw hole block, the front end of the screw rod is mounted in a bearing seat of a rear trolley frame, the rear end of the screw rod rotatably stretches out of a front trolley frame and is provided with a rocking handle, a platform is mounted on the upper face of the support, and a push-pull frame is mounted on the rear face of the trolley frame. Due to the fact that the manual lifting platform is simple in structure, small in size and capable of being lifted, workpieces being mounted or demounted on site can be carried through manual operation, and the manual lifting platform has the advantages of being convenient to use, saving manpower, reducing cost, improving efficiency, and guaranteeing safety.
