Rated Total Load Chart for 850 kg
Searcher Hook
DANGER!
• When using the searcher hook, be sure to
set searcher hook mode for moment limiter.
• Fall mode/option mode and searcher hook
position must be set as "searcher hook
mode" when 850 kg searcher hook is used.
Searcher hook position must be displayed
on moment limiter boom length window.
• Never use the searcher hook and the crane
hook simultaneously.
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 850 kg
searcher hook (30 kg), block/ball and all
rigging.
5. The capacity when using the searcher hook
refers to the capacity with the crane hook
detached.
6. If boom (3) is extended to any extent, work
should be performed within the capacity for
"10.655m Boom".
7. If boom (4) is extended to any extent, work
should be performed within the capacity for
"13.565m Boom".
8. 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 "16.475m Boom".
9. 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.
10. 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.
11. This operating range chart does not include
boom deflections.
12. At certain working conditions, moment limiter
may display bigger load value the actual
load.
13. 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 40 degree boom
angle.
