Supplemental Data - Barge
1. Rated loads included in the charts are the maximum
allowable freely suspended loads at a given boom
length, boom angle and load radius, and have been
determined for the machine standing level on firm
supporting surface under ideal operating conditions.
The user must limit or de-rate rated loads to allow for
adverse conditions (such as soft or uneven ground,
out-of-level conditions, wind, side loads, pendulum
action, jerking or sudden stopping of loads,
inexperience of personnel, multiple machine lifts, and
traveling with a load).
2. Rated loads do not exceed 75% of minimum tipping
loads. Rated loads based on factors other than
machine stability such as structural competence are
shown by asterisk * in the charts.
3. The machine must be reeved and set-up as stated in
the operation manual and all the instruction manuals if
these manuals are missing, obtain replacements.
•
Machine shall be positively secured to prevent
shifting.
•
Boom backstops are required for all boom length.
•
Gantry must be fully raised position for all
operations.
•
Crawlers must be fully extended and be locked in
position.
•
Must have 76,300 lbs (5) Counterweights fully
installed.
•
Must have 14,300 lbs (2) Carbody weights fully
installed.
4. Do not attempt to lift where no radius on load is listed
as crane may tip or collapse.
5. Attempting to lift more than rated loads may cause
machine to tip or collapse. Do not tip machine to
determine rated loads.
6. Weight of hooks, hook blocks, slings and other lifting
devices are a part of the total load. Their total weight
must be subtracted from the rated load to obtain the
weight that can be lifted.
7. When lifting over boom point with jib or auxiliary
sheave, rated loads for the boom must be deducted
as shown below.
When auxiliary sheave is used for 10 or 9 reeving
parts of line, it is not required to deduct 700 lbs from
rated loads.
8. To install the jib is prohibited when the machine is on
a barge.
9. The total load that can be lifted over an auxiliary
sheave is the value for 700 lbs deducted from rated
load for the boom without auxiliary sheave, but it
should not exceed auxiliary maximum hoist loads.
10. Boom lengths that can attach auxiliary sheave are from 50 ft
(15.2 m) to 220 ft (67.1 m).
11. The boom should be erected over the front of the crawlers,
not laterally.
12. Least stable position is over the side.
13. Maximum hoist load for number of reeving parts of line for
hoist rope.
14. Assembling the Counterweight
15. Weight of recommended hook block.
Warning: If the weight of the hook block to be used is lighter
than the recommended weight, the jib may turn over
backward or will be difficult to lower the empty hook block.
16. Rated loads listed apply only to the machine as originally
manufactured and designed by KOBELCO CONSTRUCTION
MACHINERY CO., LTD. Modifications to this machine or use
of equipment other than that specified can reduce operating
capacity.
17. Designed and rated to comply with ANSI Code B30.5.
