Use the lower value from the chart when the boom length or working radius is between the range of values. Never operate the crane beyond the limit shown in the chart. 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. 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).
Take boom deflection into consideration before beginning a lifting operation. 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. The weight of above-mentioned devices should be deducted from the rated lifting load.Ģ. 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.
