Supplemental Data

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.

The crane must be leveled to within 1% on a firm

supporting surface.

Boom backstops are required for all boom length.

Gantry must be fully raised position for all

operations.

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 30 ft

40 ft

50 ft

60 ft

Deduct (lbs)

320

2,400 3,200 4,200 5,200

8. The total load that can be lifted by jib is limited by

rated jib loads.

9. Boom lengths for jib mounting are 80 ft (24.4 m) to

180 ft (54.9 m)

10. The total load that can be lifted by the auxiliary

sheave is the value for 320 lbs deducted from rated

load for the boom (without auxiliary sheave installed);

however, the auxiliary sheave rated load should not

exceed 17,000 lbs.

11. Boom lengths that can attach auxiliary sheave are from

40 ft (12.2 m) to 190 ft (57.9 m).

12. The boom should be erected over the front of the

crawlers, not laterally. When lifting from or lowering to the

ground the boom at length of 180 ft (54.9 m) with jib, the

blocks for erections must be placed at the end of the

crawlers.

13. Least stable position is over the side.

14. Maximum hoist load for number of reeving parts of line for

hoist rope.
