The invention belongs to the technical field of crane manufacturing and relates to a quick-assembly tower crane. The quick-assembly tower crane comprises an upper tower body and a lower tower body, wherein the upper tower body can be compressed into the lower tower body, so that a telescopic structure is formed; the tower bodies are compressed or stretched through a tail inhaul cable system. Tower arms include a front tower arm and a rear tower arm which are connected through a pin shaft, and the tower arms are folded leftwards and rightwards through an arm unfolding rope. The first section at the bottom of each tower body is arranged to be of an isosceles right triangle structure, and the bottom of the lower tower body is of a foldable structure in a pin shaft connection mode. Meanwhile, two erection rods are arranged to maintain the overall stability of the tower crane. The tower crane is assembled quickly through the tail inhaul cable system, a raising and winching system, a rotation system and the arm unfolding rope system. The quick-assembly tower crane has the advantages of being quick in assembling, safe in operation, low in cost, convenient to use and the like.
