LJ Operating condition
Notes: Figures in framed cells indicate that the
rated load depends on the 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 75
percent of the load depending on stability or
structure.
