Bridge-type grab ship unloader is a sort of specialized bulk handling equipment.

The kinematics mechanism of bridge-type grab ship unloader mainly includes hoist supporting mechanism, hoist switching mechanism, trolley mechanism, pitching mechanism and travel mechanism.

The core techniques of bridge-type grab ship unloader

1. electronic anti-sway techniques
2. semi-automated optimized path control
3. static unloading, dynamic unloading
4. grab automatically switching and  deep-excavation control
5. hoisting slip proof control
6. synchronous lifting control
7. moment balance control
8. steel rope over-relaxation control
9. automated pitching control
10. complete safety protection for electronic control system
11. ship unload CMS
