The invention provides a tower type crane with double hoisting arm sections. The tower type crane comprises a tower body, a first arm section and a second arm section, wherein the first arm section is connected with the tower body, the second arm section is connected with the first arm section, and a folding mechanism is arranged between the first arm section and the second arm section; after being folded, the first arm section and the second arm section are in a level adjacent state under the effect of the folding mechanism. Compared with an old fixed hoisting arm tower machine, hoisting arms are mutually hinged and folded together through the folding mechanism, so that the transporting height is reduced, and the tower type crane is convenient to transport; the hoisting arm can be orderly unfolded from a folded state to the level state under the effect of a power system, the mounting time of the tower machine is greatly shortened, and the cost of a low-rise building and a plant building is reduced.
