The invention relates to a serialized multi-type small-size manned lifter arranged in a V-shaped cat ladder of a wind generator tower drum. The wind tower lifter can be directly arranged at the inner side of the V-shaped cat ladder of the wind generator tower drum, and a main engine is arranged between two sets of guide rails. A chain or a wire rope hanging on the top of the V-shaped cat ladder is tensioned downward through a traction wheel set in a case, so that the main engine is enabled to hang at the inner side of the V-shaped cat ladder. An electromotor in the case is started, the operation of the traction wheel sets are slowed down by a worm reduction gear; the main engine can run up and down along the guide rails by traction of the chain or the wire rope, or two sets of gear racks, gear bands or chains, which are with the same teeth spaces, are arranged; two wheel gears or two chain wheels, which are with the same number of teeth, arranged at the two ends of an output shaft of the worm reduction gear, are identical with the two sets of gear racks, gear bands or chains; the main engine is arranged at the inner side of the V-shaped cat ladder, The electromotor in the case is started, and the main engine is driven to run up and down along the guide rails by the operation of the two wheel gears or chain wheels at the two ends of the output shaft of the worm reduction gear.
