    Abstract
  • The productivity calculation methods of different grab ship unloaders were analyzed, the advantages, disadvantages and applicability were compared, a new performance evaluation method was presented based on mechanical performance calculation approaches.The validity rules of testing record were established, some modified coefficients were defined to eliminate the influence of uncertain factors such as material attributes and operation conditions.Calculation result shows that the rating productivity of automatic operation mode is increased by 3.12% than that of manumal mode, and actual productivity is increased by 7.97%, so the evaluation result is acturate, and the new method can easily compare the automation degrees of different manipulation modes.
