Technical Field

The present application relates to the technical field of ship loading and unloading machines, and in particular to a multifunctional mobile double-slewing bridge grab bucket ship loading and unloading machine.

Background Art

Ship loaders and ship unloaders are mechanical equipment used in ports and docks to load or unload materials, and have important applications in the field of material transportation. In the prior art, ship loaders and ship unloaders are usually separated and can generally only load or unload separately. When facing loading, unloading, barge loading and unloading and other working situations in ports, it is necessary to repeatedly switch between ship loaders or ship unloaders, resulting in a decrease in the working efficiency of the port. In addition, when ship loaders and ship unloaders are placed at the same time in the port, the space of the port will be compressed, which is not convenient for the transportation of materials. Therefore, in order to expand the space, the dock needs to be increased in length, and the construction cost and investment cost also increase accordingly. Therefore, a multifunctional mobile double-slewing bridge grab ship loader and unloader is urgently needed to improve the above problems.
