The invention discloses a tower crane capable of adjusting a lifting contact area, and relates to the technical field of hoisting. The tower crane comprises a supporting frame, wherein a hanging basket is mounted at the bottom of a translation mechanism, a driving mechanism for adjusting the transverse movement of the translation mechanism is arranged on the side wall of a lifting frame, extensionplates which are symmetrically arranged are slidably mounted on the two sides of the supporting frame, an extension mechanism for adjusting the extension plates to stretch is arranged in the supporting frame, and a guide mechanism is connected between the extension mechanism and the supporting frame. According to the tower crane, a steel wire rope is wound and placed through the arrangement of the driving mechanism, a sliding frame is driven to adjust the transverse position of the hanging basket under the elastic reset effect of a reset mechanism, and the carrying effect on goods in the hanging basket is achieved; and the arranged extension mechanism can drive the extension plates to slide and adjust towards the two sides of the supporting frame under the driving of a servo motor, a supporting area range can be flexibly adjusted according to the requirement of the actual support stability, and the stable supporting effect of the supporting frame and the extension plates on the deviceis ensured.
