The invention discloses a tower crane. The tower crane comprises a lengthened sliding device with a sliding lengthened rod structure therein. The lengthened sliding device comprises an installing frame. An open containing cavity is formed in the installing frame and is of a triangular open structure. A plurality of fixed crossed rods are fixedly arranged between the end walls of the containing cavity. The fixed crossed rods are fixed obliquely in a triangular shape. The rightmost side of the lengthened sliding device is provided with a sliding hanging device which can be matched and connectedwith the lengthened sliding device and used for hanging objects. It is avoided that personnel safety is affected by the breakage and damage of the device due to the lengthened type arrangement in rainy and snowy days. Meanwhile, by means of the telescopic mode, the tower crane can achieve the basic cargo moving and carrying function. Cushion blocks, guide rods and the fixed crossed rods are designed with the purpose of increasing the firmness and stability of the device structure. Due to the triangular arrangement, the stability of the structure in the device is better increased.
