Notes: The grey filling part specified in the above table is determined by strength.
Notice: 1. the actual hoisting capacity shall be the value of rated hoisting capacity deducting the weight of hook blocks, wire ropes
and all the spreaders.
2. The rated load shown in the table is the weight of cargo which is slowly and steadily lifted by crane on flat and hard ground under
the non-travel load condition.
3.The load rating is calculated not exceed 75percent of the load depending on stability or structure.
