The invention discloses rotary speed reduction equipment of an engineering tower crane. The rotary speed reduction equipment comprises the tower crane, a winding drum, a first bearing seat, a second bearing seat, a winding drum shaft, a first motor, a speed reducer and a transfer assembly; the tower crane comprises a balance arm frame; the first bearing seat and the second bearing seat are both fixed to the upper surface of the balance arm frame; a connecting line between the first bearing seat and the second bearing seat is perpendicular to the length direction of the balance arm frame; a winding drum is coaxially and fixedly arranged on the winding drum shaft in a sleeving manner; the winding drum is used for winding a traction rope; and one end of the winding drum shaft is rotationallyconnected to the first bearing seat through a bearing, and the other end of the winding drum shaft is rotationally connected to the second bearing seat through a bearing. The probability that a speedreducer shell, an output end bearing and an oil seal are damaged due to composite stress can be greatly reduced, and therefore normal and safe operation of the tower crane is guaranteed.
