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 lifted 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
searcher hook (22 kg), as well as block/ball
and all rigging.
5. 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.
6. 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 manufacturer, can result
in a reduction of rated total load ratings.
7. This operating range chart does not include
boom deflections.
8. At certain working conditions, moment limiter
may display bigger load value the actual load.
9. 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 50
degree boom angle.
In SH2 position, do not operate above 75
degree boom angle.
