The invention provides a tower crane variable-amplitude trolley motor replacing device and method. The device comprises a supporting part, a rotating part, a suspension part and a chain block, whereinthe supporting part comprises a top plate which is fixed at the upper end of an upper chord of a cargo boom, the rotating part comprises a vertical shaft fixed to the upper end of the top plate and arotating sleeve arranged on the periphery of the vertical shaft in a sleeving mode so that the suspension part can rotate around the vertical shaft, the suspension part comprises a suspension arm, one end of the suspension arm is fixedly connected with the upper end of the rotating sleeve, a baffle is arranged at the other end of the suspension arm, two connecting plates are symmetrically arranged on the two sides of the suspension arm in the width direction, two pin holes are formed in each of the two connecting plates in the vertical direction at an interval, a pulley is installed at the upper end of the suspension arm through pin shafts penetrating through the pin holes in the upper portions of the connecting plates, pin shafts penetrating through the pin holes in the lower portions ofthe connecting plates serves as a hoisting point of a chain block, and an upper hook of the chain block is hung on the hanging point. According to the device and the method, the maintenance work of amotor can be completed by a single person, and the motor can be dismounted and mounted by 360 degrees without dead angles by utilizing the rotation of the suspension arm, the sliding of the pulley and the lifting and lowering of the chain block.
