Note

• The total rated loads given in the rated load charts  are the maximum lifting capacity when the crane is  set up on firm and level ground, which includes the  weight of the hook block and slings. The weight of  above-mentioned devices should be deducted to  correctly calculate the load weight. 

• The working radius shown in the rated load charts  is the radius when the load is lifted off the ground,  and it is the actual value including loaded boom  deflection. 

• A lifting operation is permissible only when the  wind force is below grade 5 (instantaneous wind  speed is 14.1 m/s, wind pressure is 125 N/m2 ). 

• Before beginning lifting operation, the operator  should know the weight of the load to be lifted and  its working range, and then select proper working  conditions. Never operate the crane beyond the  limit shown in the chart. Use the lower value from  the chart when the boom length or working radius  is between the range of values. 

• Observe the boom angle limit. Never operate the  crane with the boom angle beyond the  recommended limit even if a load is not being  carried. Otherwise, the crane will tip. 

• The boom length given in the rated load charts  should accord with the telescoping code of boom  sections .
