Multi-pylon multi-span lifting cable crane

The invention discloses a multi-pylon multi-span lifting cable crane. The crane comprises M pylons, N lifting spans connected to the M pylons sequentially, bearing cables, an overhead crane and lifting appliance assembly, traction systems, lifting systems and anchorage systems, wherein each pylon comprises a cable tower and a main tower arranged at the top of the cable tower, and a cable saddle structure for supporting the corresponding bearing cable is arranged at the top of the main tower; two ends of single bearing cable are used for being connected with the anchorage systems located on both banks; one lifting span is formed between every two adjacent pylons, and at least two lifting spans are connected to form a multi-pylon multi-span structure; the traction systems are used for pulling the single overhead crane and lifting appliance assembly to move between the adjacent lifting spans, and the lifting systems are used for lifting materials through the overhead crane and lifting appliance assembly; N and M are both natural numbers, M is larger than or equal to 3, and N is equal to the difference between M and 1. Therefore, multiple lifting spans are formed by arranging multiple pylons, and compared with the conventional double-pylon single-span lifting cable crane, the height of each pylon is reduced substantially and controlled effectively.
