The Total Rated Load Charts are based on the actual working radius including boom deflection. The weight of the hook (standard 4 fall - 30kg) must be included as part of the load shown in the Total Rated Load Charts.
When using two fall or single fall hooks, use the appropriate four fall Total Rated Load Chart above but with a maximum load of: Two Fall - 1480kg, Single Fall - 750kg.
