Abstract

The tire gantry crane comprises the diesel generating system and city electric supply system, with the power system generating through diesel generator, power system referring to city power supply that provides low voltage power supply, with diesel power supply and city power supply system being able to supply power to crane independently, and being able to supply power to the crane simultaneously. It is simple and convenient for the crane, with safe, reliable, convenient maintenance, reduced oil consumption, running and maintenance cost, with less pollution to the environment.

Description

technical field [0001] The present invention relates to lifting equipment used for wharfs, ports, and operation transportation, and more specifically, relates to a rubber-tyred gantry crane, which can be powered by mains power, perform normal stacking operations, and reduce operation and maintenance costs. Background technique [0002] At present, the traditional rubber-tyred gantry crane (RTG) uses a diesel generator set as the power device, and uses diesel for power supply, so that the crane can be moved in the container yard, and can also be transferred, which is convenient for operation and free from dragging cables and external forces. The impact of the power supply has the advantages of good flexibility and mobility. However, due to the high fuel consumption of the crane and the sharp rise in global oil prices, the operating cost of the crane, which relies solely on diesel as energy, continues to rise. In addition, the maintenance cost of the diesel generator set is al...
