10. Lifting off the main boom point while the swing-
around jib is erected is not intended or approved.
11. All load ratings above the heavy line are based on
machine structural competence and do not exceed 85%
of tipping. Load ratings below are stability limited and
do not exceed 85% of tipping.
12. Do not operate a Manitowoc truck-mounted crane
or accessories within 10' (3,05 m) of live power lines.
13. This capacity chart is for reference only and must
not be used for specific serial number cranes.
Information
1. Deductions must be made from rated loads for stowed
jib, optional attachments, hooks, and loadblocks (see
deduction chart). Weights of slings and all other load-
handling devices shall be considered a part of the load.
2. Load ratings above the heavy line are structurally limited
capacities. Load ratings below the heavy line are stability
limited capacities and do not exceed 85% of tipping.
Definitions
1. Operating radius (r ) is the horizontal distance from
the axis of rotation to the center of the vertical hoist line
or tackle with load applied (see below).
2. Loaded boom angle (
Є), as shown in the column
headed by
Є, is the included angle between the
horizontal and longitudinal axis of the boom base after
lifting rated load at rated radius (see below).
installation. Designed to withstand high pressure
washing and varying climates.
Design/Welding –
Design conforms to ANSI B30.5.
Welding conforms to AWS D1.1. Tested to SAE 1063
and SAE 765.
Manuals –
Operator, service and parts manuals depict
correct crane operation, maintenance procedures and
parts listing.
Warranty – 12-month warranty covers parts and labor
resulting from defects in material and workmanship.
Warning
1. The operator must read and understand the owner’s
manual before operating this crane.
2. Positioning or operation of crane beyond areas shown
on this chart is not intended or approved except where
specified in owner’s manual.
3. Loaded boom angles at specified boom lengths give
only an approximation of the operating radius. The
boom angle before loading should be greater to
account for deflections. Do not exceed the operating
radius for rated loads.
4. The operating radius shown in the jib rating chart is
for fully extended boom only. When boom is not fully
extended, use only loaded boom angle to determine load
rating of jib.
5. For boom angles shown on jib load rating chart, use
rating of next lower boom angle.
6. For boom lengths not shown, use rating of next
shorter or longer boom length, whichever is less. For
radii not shown, use rating of next longer radius.
7. Crane load ratings on outriggers are based on freely
suspended loads with the machine leveled and standing on a
firm, uniform supporting surface. No attempt shall be made
to move a load horizontally on the ground in any direction.
8. Practical working loads depend on supporting surface,
wind, and other factors affecting stability such as
hazardous surroundings, experience of personnel, and
proper handling, all of which must be taken into
account by the operator.
9. The maximum load which may be telescoped is
limited by hydraulic pressure, boom angle, and boom
lubrication. It is safe to attempt to telescope any load
within the limits of the load rating chart.
