Bridge grab type ship unloader accessories

1. Main electrical accessories

The various main electric control equipment configured on the bridge grab type ship unloader, such as the upper machine high-voltage drum cable, high-voltage switch cabinet, high-voltage transformer, whole machine low-voltage cable, air conditioning system, etc., can be completely made of domestic brands or domestic joint venture brands. The high-power main motors such as lifting and closing have high working levels and high use intensity. In actual operations, they are constantly performing forward and reverse rotation and acceleration and deceleration movements. There are very high requirements for the quality of the motor. Domestic motors have begun to be put into use. With the improvement of quality, there will be better development space.

In the configuration of the variable frequency drive system, domestic inverters have been mature and successfully used on multiple ship unloaders with good results, which is worthy of large-scale promotion. However, in terms of PLC controllers, due to the shortcomings of semiconductor hardware, domestic supporting products still need greater technological progress.

2. Main mechanical accessories

With the continuous improvement of my country's manufacturing level, various mechanical accessories on differential ship unloaders, such as reducers, wire ropes, brakes, hydraulic components and systems, long-strut grabs, pear-shaped quick connectors, etc., have formed a large-scale industrial chain, and have made breakthrough developments in quality, which can fully meet the working requirements of unloading machinery.
