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.
•
Must have 199,300 lbs (14) Counterweights fully
installed.
•
Must have 60,500 lbs (4) 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.
Jib Length Aux Sheave 40 ft
60 ft
80 ft
100 ft
Deduct (lbs)
700
Not Applicable
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 59,500 lbs.
10. Boom lengths that can attach auxiliary sheave are
from 50 ft (15.2 m) to 290 ft (88.4 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.
