Description

Technical Field

[0001] The invention relates to a wall attaching device for a tower crane and the tower crane. Background Art

[0002] In the construction of high-rise buildings, tower cranes are the main construction machinery and play an important role. Since there is a certain distance between the tower crane and the building, in order to ensure the stability of the tower crane, the tower crane needs to be connected to the building through a wall attachment device.

[0003] The current wall-mounted device is mainly composed of embedded parts, a wall-mounted frame and a support beam. One end of the support beam is connected to the wall-mounted frame, and the other end of the support beam is connected and fixed to the embedded parts on the wall to achieve the purpose of support. When the tower crane needs to move, the connection and fixing relationship between the other end of the support beam and the embedded parts on the wall must be released. After the tower crane moves, the other end of the support beam must be reconnected and fixed to the embedded parts on the wall. Through the above analysis, it can be seen that the current wall-mounted device needs to undergo disassembly and assembly operations during the movement of the tower crane. The disassembly and assembly operations of the wall-mounted device will increase the on-site construction time and affect the construction period.

[0004] In view of the above situation, the applicant proposed a tower crane with a walking mechanism on August 2, 2015. The
