The crane 100 includes: a chassis 2; a crawler running device 5 disposed on both sides of the chassis 2 for walking of the crane; and a boom 1 hinged to the chassis 2 The middle turntable (rotating mechanism) 7 is on. Preferably, the chassis 2 comprises a pontoon structure, and the crawler walking device 5 is two sets, and each set includes two pontoons 51 arranged side by side and fixed to each other. In particular, the crane 100 according to an embodiment of the present invention further comprises: a cantilever beam 3 extending from the chassis 2, in particular in this embodiment, detachably hinged to the turntable 7 of the chassis 2 and preferably as shown in FIG. The hollow barrel-shaped foundation 4, which is open at the lower end and closed at the upper end, has a closed upper end detachably suspended at the free end of the cantilever beam 3, and a lower end thereof can be extended below the ground during lifting work, thereby greatly Enhance the stability of the support and ensure the smooth lifting operation, which is very advantageous in the shoal area or shallow water area where the ground support is poor. Thus, the cantilever beam 3 and the bucket base 4 constitute the support means of the crane 100 to support the weight of the crane during crane operation, and the support device can be disassembled for transport alone during the crane walking or transition. A telescopic support member 6 is preferably disposed between the chassis 2 and the crawler track device 5, the upper end of which is coupled to the chassis 2, and the lower end thereof is coupled to the crawler travel device 5, the telescopic support member may include a hydraulic cylinder to adjust the height of the chassis 2 . The cantilever beam 3 and the barrel foundation 4 are installed before lifting work. The cantilever beam 3 is rotatable about the turntable 7 and is expandable and contractable along its length to adjust the support points on the barrel base 4. After the support point has been positioned, the barrel base 4 can preferably be connected to the free end of the cantilever beam 3 by means of a connector 11 that can be telescoped in the longitudinal direction in order to ensure that the crane 100 is stably supported by the barrel base 4. The cantilever beam 3 can be raised, for example, by hydraulic driving, so that the poncho-type crawler running device 5 does not contact the ground but provides work stability as a counterweight (see Fig. 2).

In the transition state, as shown in Fig. 3, the boom 1, the cantilever beam 3, and the barrel base 4 are detachable for separate transportation. In this embodiment, the chassis 2 may include a pontoon structure to provide greater buoyancy during deep water operation, to ensure equipment safety, and to facilitate installation, the pontoon structure may be floated by multiple splits The box structure is combined. In addition, the pontoon type crawler running device 5 is preferably two sets and symmetrically arranged on the left and right sides of the crane chassis 2 to increase the grounding area of the crane and improve the passability. Preferably, as shown in FIG. 1, each set of crawler walking devices 5 includes two floating boxes 51 (only one is shown in FIG. 1) arranged side by side and fixedly connected to each other and corresponding to each floating box. Set the track 52. Since the pontoon type crawler walking device is provided, if it is driven in shallow water, it can provide buoyancy for the entire equipment, reduce the grounding specific pressure, and provide transparency; and when it is deep, it can float to ensure equipment safety. Since each set of crawler walking devices includes two parallel pontoons, the size of the single pontoon is reduced and the installation is convenient. According to the crane 100 of the embodiment of the present invention, when walking in the shallow sea, if the water surface is raised, in order to reduce the impact of the tidal water on the equipment and prevent the crane from being affected, the hydraulic oil of the telescopic support member 6 can be activated to elongate, thereby making the chassis 2 is then raised to enable the crane 100 to walk and work in shallow water areas. Although the present invention has been described in connection with what is presently considered as a practical exemplary embodiment, those skilled in the art will understand that the invention is not limited to the disclosed exemplary embodiments. Any modifications, equivalent substitutions, improvements, etc. within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
