Dotrum Portal crane:
① Dockside portal slewing crane for loading and unloading: It is mainly used in ports and open storage yards. It is loaded and unloaded by grabs or hooks. Lifting capacity generally does not exceed 25 tons, does not change with the amplitude. High working speed, so productivity is often an important indicator.
②Portal crane for shipbuilding: It is mainly used in shipyards, floating docks and outfitting sites for hull splicing and equipment outfitting, and hooks are used as lifting gear. The maximum lifting capacity is 300 tons, and the lifting capacity decreases correspondingly when the range is large. There are multiple gear lifting speeds, which can be increased when the weight is light. Some working mechanisms are also equipped with micro-movement devices to meet installation requirements. If the height of the door seat is large, it can meet the requirements of large lifting height and large-scale operation, but the work speed is low and the productivity is not high.
③Portal gantry crane for construction: It is mainly used for dam irrigation, equipment and prefabrication of hydropower stations, and generally used hooks.
