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.

    本发明公开了一种具有调节起重接触面积的塔式起重机,涉及起重技术领域,包括支撑架,平移机构底部安装有吊篮,所述升降架侧壁设有用于调节平移机构横向移动的驱动机构,所述支撑架两侧滑动安装有对称设置的延伸板,支撑架内设有用于调节延伸板伸缩的伸展机构,所述伸展机构与支撑架之间连接有导向机构;本发明通过设置的驱动机构能对钢丝绳绕卷和放设,在复位机构的弹性复位作用下实现滑动架带动吊篮横向位置调节,实现对吊篮内货物的搬运作用,设置的伸展机构能在伺服电机的驱动下带动延伸板朝支撑架两侧滑动调节,实现根据实际的支撑稳定度的要求对支撑面积范围进行灵活调节,保证支撑架连同延伸板对本装置的稳定支撑作用。
