1. Rated loads included in the charts are the maximumallowable freely suspended loads at a given boomlength, boom angle and load radius, and have beendetermined for the machine standing level on firmsupporting surface under ideal operating conditions.The user must limit or de-rate rated loads to allow foradverse conditions (such as soft or uneven ground,out-of-level conditions, wind, side loads, pendulumaction, jerking or sudden stopping of loads, inexperi-ence of personnel, multiple machine lifts, and travelingwith a load).
2. Rated loads do not exceed 75% of minimum tippingloads. Rated loads based on factors other thanmachine stability such as structural competence areshown by asterisk * in the charts.
3. The machine must be reeved and set-up as stated inthe operation manual and all the instruction manuals ifthese manuals are missing, obtain replacements.1) The crane must be leveled to within 1% on a firm
supporting surface.2) Boom backstops are required for all boom
lengths.3) Gantry must be fully raised position for all opera-
tions.4) Crawlers must be fully extended and be locked in
4. Do not attempt to lift where no radius on load is listedas crane may tip or collapse.
5. Attempting to lift more than rated loads may causemachine to tip or collapse. Do not tip machine todetermine rated loads.
6. Weight of hooks, hook blocks, slings and other liftingdevices are a part of the total load. Their total weightmust be subtracted from the rated load to obtain theweight that can be lifted.
7. When lifting over boom point with jib or auxiliarysheave, rated loads for the boom must be deductedas shown below.
8. The total load that can be lifted by the jib is limited byrated jib loads.
9. Boom lengths for jib mounting are 80 ft (24.4 m) to 180ft (54.9 m).
10. The total load that can be lifted by the auxiliary sheaveis: the rated load for the boom (without auxiliarysheave installed) minus 320 lbs; however, the auxiliarysheave rated load should not exceed 17,000 lbs.
11. Permissible boom lengths for installing auxiliarysheave are from 40 ft (12.2 m) to 190 ft (57.9 m).
12. The boom should be erected over the front of thecrawlers, not laterally.
13. Least stable position is over the side.
14. Maximum hoist load for number of reeving parts of linefor hoist rope.
15. Rated loads listed apply only to the machine asoriginally manufactured and designed by KOBELCOCRANES CO.,LTD. Modifications to this machine oruse of equipment other than that specified can reduceoperating capacity.
16. Designed and rated to comply ANSI code B30.5.

4. The combined weight of the bucket and load must not exceed these capacities.5. Boom length for clamshell operation should not exceed 70 ft (21.3 m).
3. Capacities are maximum recommended by PCSA Standard #4. Allowances must be made by the user for such unfavorable conditions as a sort of uneven supporting surface, rapid cycle operations, or bucket suction.
