A crane lifting mechanism comprises a walking mechanism, a lifting mechanism body and a brake mechanism. The lifting mechanism body comprises a lifting motor, a speed reducer and a cable winding drum, wherein the speed reducer is connected with a brake wheel, and a brake jaw is arranged on the lower side of the brake wheel and connected with an electric telescopic rod. The brake mechanism comprises a brake shoe and a brake board slot, and a screw penetrates through the brake board slot. A baffle is arranged on the upper side face of the brake shoe, a buffer spring is arranged on one side of the baffle, and a cam shaft is arranged on the other side of the baffle. The cam shaft is connected with a transverse rod, the transverse rod is connected with a driving rod which is connected with a push rod, and the push rod is connected with a pusher. A protective hood is arranged on the outer side of the brake shoe and provided with an adjusting rod B. An eccentric shaft is arranged on the brake shoe, a ratchet wheel is arranged at the right end of the eccentric shaft and connected with an adjusting rod A, a pawl base is arranged on the outer side of the eccentric shaft, and a pawl is hinged to the pawl base.
