11. When spin resistant wire is used, the allow-
able rope loading shall be the breaking
strength divided by five (5) unless otherwise
specified by wire rope manufacturer.
OPERATION
12. Crane load ratings must not be exceeded.
DO NOT ATTEMPT TO TIP THE MA-
CHINE TO DETERMINE ALLOWABLE
LOADS.
13. Crane load ratings are for lift crane service.
Applications for other than lift crane (clam-
shell and magnet) are permitted. Due to
significant variations in materials and appli-
cations, consult factory for optimum capabil-
ity.
14. Weight of hooks, hook blocks, slings and all
other load handling devices must be consid-
ered part of the load to be handled and must
be subtracted from the load ratings to obtain
the allowable load to be lifted.
15. Crane load ratings are based on freely sus-
pended loads. SIDE LOAD ON BOOM OR
JIB IS EXTREMELY DANGEROUS.
16. Practical working loads depend on the sup-
porting surface, wind velocity, pendulum
action, jerking or sudden stopping of loads,
hazardous surroundings, experience of per-
sonnel, proper operation, tire inflation, tire
condition, traveling with loads, multiple
machine lifts, proximity of electrical wires,
etc. Appropriate reduction of load ratings
must be made for these and any other condi-
tions which may affect practical working
loads.
17. Crane load ratings with an asterisk (*) beside
them are based on the machine’s structural
strength. All other ratings are based on
stability and do not exceed the specified
percentage of tipping load as determined by
SAE Crane Stability Test Code J765a.
18. For all boom lengths between the retracted
and extended boom length, the rated loads
are determined by boom angle only shown in
the extended boom column. For boom angles
not shown, use capacity of the next lower
boom angle.
19. When either radius or boom length, or both,
are between listed values, the smaller of the
two load ratings shall be used.
20. Load ratings are dependent upon the crane
being maintained according to manufacturer’s
specifications.
21. The maximum load which may be telescoped
is limited by boom angle, hydraulic pressure,
boom lubrication, etc. It is safe to attempt to
extend and retract within the limits of the ca-
pacity chart.
22. It is recommended that load handling de-
vices, including hooks and hook blocks, be
kept away from boom head at all times.
23. The boom angles shown on the capacity chart
give an approximation of the operating radius
for a specified boom length. The boom
angle, before loading, should be greater to
account for boom deflection.
24. DO NOT LIFT LOAD OVER OPERATOR.
