Shipyard Portal Cranes

Shipyard portal cranes are mainly used in ship platforms, floating docks and outfitting sites for hull splicing, equipment outfitting and other lifting work, using the hook as a spreader. The maximum lifting capacity is up to 300 tons, and the lifting capacity is reduced accordingly when the amplitude is large. There are several lifting speeds, and the lifting speed can be increased when the lifting weight is light. Some of the working mechanism is also equipped with micromotion device to meet the installation requirements. Door seat height is large, can adapt to the requirements of large lifting height and large-scale operation, but the working speed is low, the operation productivity is not high.
