Larger cranes and higher speed require high operating skills. The GSU automation system from ABB enables safe, reliable and efficient bulk cargo handling and supports the operator throughout the cycle. The automation system allows higher speed and steady pace of the grab, which increases productivity. It runs the crane smoothly, which in turn reduces wear and tear as well as mechanical shock. This reduces the maintenance cost. The automation system also reduces operator fatigue and allows the operators to perform better through his shift.

ABB Grab Ship Unloader Automation System consists of the following functions:

  • Grab sway control in hatch and flying unloading over hopper
