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. The boom should be erected over the front of the
crawlers, not laterally. When erecting and lowering the
crane boom at a length of 290 ft (88.4 m) or over, and
the crane boom with fixed jib at a length of 250 ft
(76.2), the blocks for erections must be placed at the
end of the crawlers.
7.
(Crane Boom Lifting)
The total load that can be lifted is the value for weight
of the main hook block, slings, and all other load
handling accessories deducted from the crane boom
ratings shown..
8.
(Crane Boom Lifting with Auxiliary Sheave Frame)
The total load that can be lifted is the value for the
weight of the main hook block, auxiliary sheave hook
block, auxiliary sheave (700 lbs), slings, and all other
load handling accessories deducted from the crane
boom ratings shown.
9.
(Auxiliary Sheave Lifting for Crane Boom)
The total load that can be lifted is the value for the
weight of the main hook block, auxiliary sheave hook
block, auxiliary sheave (700 lbs), slings, and all other
load handling accessories deducted from the crane
boom ratings shown, but should not exceed 59,500
lbs.
Boom lengths that can attach auxiliary sheave are
from 50 ft (15.2m) to 290 ft (88.4m).
10.
(Crane Boom Lifting with Fixed Jib)
The total load that can be lifted is the value for the weight
of the main hook block, slings, and all other load handling
accessories deducted from the crane boom with fixed jib
ratings shown.
Boom lengths for jib mounting are 90 ft (27.4m) to 250 ft
(76.2m).
11.
(Fixed Jib Lifting)
The total load that can be lifted is the value for the weight
of the jib hook block, slings, and all other load handling
accessories deducted from the fixed jib ratings shown.
Boom lengths for jib mounting are 90 ft (27.4m) to 250 ft
(76.2m).
One part line on hook block is not allowed for use on 40 ft
(12.2m) jib length with offset angle of 10 degrees.
12. Least stable position is over the side.
13. Maximum hoist load for number of reeving parts of line for
hoist rope.
