The invention discloses a crank type lift. The crank type lift comprises a crank type lift main body, fixed leg supports and an emergency landing structure, wherein one fixed leg support is arranged at each corner of a machine body of a crank type lift main body; the fixed leg supports are fixedly connected with the crank type lift main body in a welding manner; and the emergency landing structureis arranged on the surface of one side of an operation platform of the crank type lift main body and is fixedly connected with the operation platform by welding. The practical structure is reasonableand effective; and when the lifted operation platform cannot normally descend caused by machine faults, workers positioned on the operation platform can quickly return to the ground by using the emergency landing structure at the moment, so that possible peril incidents are avoided.
