6.2 RATED TOTAL LOAD CHART FOR SEARCHER HOOK
1. This Rated Total Load Chart shows the maximum allowable capacities. These rated total loads are based on
the machine standing level on a firm ground supporting surface, under ideal job conditions and a freely
suspended load.
2. Sufficient design tolerance must be used to ensure adequate ground support surface design. The rated total
loads are for static conditions only, and do not include dynamic effects of slewing, extending, retracting,
lowering, raising, wind or adverse conditions. Crane users must reduce rated total loads ratings to take all
conditions into account.
3. The Working radius shown in the Rated Total Load Chart is based on practical working radius including boom
deflection due to loading. The crane user must calculate and compensate for boom deflection as the load is
lifted.
4. Deductions from Searcher Hook Rated Total Load must be made for the weight of the 850kg searcher hook
(20kg), block/ball and all rigging.
5. If boom (3) is extended to any extent, work should be performed within the capacity for “8.145m Boom”.
6. If boom (4) is extended to any extent, work should be performed within the capacity for “10.315m Boom”.
7. When more than one half of the third
mark is exposed from the boom (3), work should be carried out
within the performance for the “12.485m Boom”.
8. All capacities above the bold line are based on structural strength and other limitations. All other rated total
loads are based on stability not exceeding 75% of tipping loads.
9. Crane users must consult the Operators Manual for complete details about assembly, operation, maintenance,
configuration, and its limitations. Modifications to the crane, other than what is specified or supplied by the
original equipment manufacture, can result in a reduction of rated total load ratings.
10. This operating range chart does not include boom deflections.
11. At certain working conditions, moment limiter may display bigger load value the actual load.
12. RESTRICTED AREA : At high boom angles, E-Boom (arm) and the hook will interfere with each other.
To avoid this interference : In SH1 position, do not operate above 30 degree boom angle.
