At present, most of tower cranes used in the building industry of China are of fixed structures of upper rotary type and upper lifting and joint rising, the rotation of a crane boom and a balance arm is realized through a rotary table arranged at the upper end of a tower body, and the gradual rising is realized through the lifting of the tower body and the addition of a foundation section, so that the traditional tower crane is suitable for large buildings or high-rise buildings, and for some crowded occasions with low-rise buildings with construction floor height of 20-40 m or more surrounding buildings, if the traditional tower crane is adopted, the size and the cost are small, the application is clumsy, and the defects of inconvenience in erection and dismantling, delay of the construction period of building engineering and the like exist; if the vehicle-mounted crane is adopted, not only is the energy consumption large and the cost high, but also the lifting height is often insufficient.

In view of this, in the prior art, an underframe and a movable support leg are fixed at the bottom of the whole machine, a rotary table is fixed on the underframe through a rotary support, a tower body and a boom are arranged on the rotary table in a foldable manner, a remotely-controlled operating seat is used for hoisting, amplitude-changing and rotating, the tower crane can be erected quickly, the tower crane is pulled by a tractor to perform short-distance transition, and the conventional traction mechanism capable of erecting the tower crane quickly is composed of common forklift tires and a welded bearing bridge. When the traction mechanism of the existing tower crane is used, the tower crane cannot carry out high-speed traction running on a highway due to the structural characteristics, so that the traction mechanism does not have the capability of long-distance transition. When the tower crane is transferred to a new site for a long distance, a special trailer is needed to drag the tower crane to the new site, and a large amount of transportation cost is increased.
