Description

Technical Field

[0001] The present invention relates to the field of quay crane assembly, and in particular to a quay crane assembly method and a quay crane assembly transport device. Background Art

[0002] The trolley travel of the shore container crane (abbreviated as quay crane in this article) is the most important component for the movement of the quay crane. During normal operation of the container terminal, since the position of the freighter is relatively fixed, the containers at different positions along the length of the freighter are moved between the quay crane and the freighter by the trolley travel, thereby loading and unloading containers at different positions on the freighter.

[0003] Currently, during the final assembly of quay cranes, the trolleys for the gantry crane travel mechanism, the balance beams at each stage, and the connected lower crossbeams are transported separately to the final assembly station, where they are assembled into components one by one. This method allows only one gantry crane travel mechanism and lower crossbeam to be assembled at a single station, requiring the same number of equipment and personnel for multiple gantry cranes. The assembly of the lower crossbeams and gantry crane travel mechanism also requires the use of large outdoor lifting equipment (floating cranes, truck cranes). This not only occupies a long assembly time, but also involves working near water, posing safety risks.

[0004] How to provide a new assembly method to achieve fast and effective assembly of quay cranes is an urgent problem that needs to be solved. Summary of the Invention
