CRANE - SUPPLEMENTAL DATA
Heavy Fixed Jib
10. Boom lengths for jib mounting are 98 ft (30 m) to 236 ft
(72 m).
Jib lengths are 59 ft (18 m), 79 ft (24 m) and 98 ft (30 m).
11. The boom should be erected over the front of the
crawlers, not laterally.
When erecting and lowering the boom length of 217 ft
(66 m) or over, the blocks for erection must be placed at
the end of the crawlers.
12. Least stable position is over the side.
13. The minimum rated load is 5,900 lbs (2.7 t).
14. Maximum hoist load for number of reeving parts of line
for hoist rope.

If the weight of hook block to be used is lighter than the
recommended weight, the boom may turnover backward
or it is difficult to lower the empty hook block.
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 derate 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.
• Boom backstops are required for all boom lengths.
• The crane must be leveled to within 1% on a firm
supporting surface.
• Counterweights and carbody weights are fully installed.
4. Do not attempt to lift where no ratings are shown 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 capacity.
6. Weight of hooks, hook blocks, slings and other lifting
devices are a part of the total load. Their total weight
must be sub-tracted from the rated load to obtain the
weight that can be lifted.
7. When main hook installed to the boom point, deduct
main hook weight from heavy fixed jib chart.
8. When lifting over boom point with jib , rated loads for
the boom must be deducted as shown below.

rated jib loads.
