Blocked Crawler Requirement
To prevent the crawler crane from tipping, some boom and
jib lengths must be raised and lowered over the end of the
blocked crawlers. See the capacity charts for blocked
crawler requirements and see Crawler Blocking Diagram in
the Capacity Chart Manual for instructions.
Extended Outriggers
To prevent the truck crane from tipping, the outriggers must
be fully extended and the carrier leveled to raise and lower
all boom and jib combinations from the ground and to the
ground—over the rear of the carrier. See Liftcrane Boom and
Liftcrane Jib Capacity Charts for the boom and jib raising and
lowering limitations.
See Outrigger Operating Controls and Operation in the
Carrier Operator Manual for the outrigger instructions.
Handling Components
Handle boom sections with care to avoid damaging the
lacings and chords. All boom inserts have lifting lugs (in top
chords) designed to provide a balanced load and to prevent
damage during lifting.
When lifting lugs are not used:
• Lift against chords only, never against the lacings.
• Use nylon lifting slings. If the wire rope or chain slings
are used, install a protective covering (such as sections
of rubber tire) between the slings and chords.
Handling Boom
See the table in the Boom Rigging Assembly drawing for
boom handling instructions.
Rigging Assembly Drawings
Boom and jib components (top, inserts, straps, pendants)
must be assembled in the proper sequence according to
Figure 4-47
, Figure 4-48, or Figure 4-49 and the Boom and
Jib Rigging drawings.
DANGER
Tipping Hazard!
Avoid death, serious injury and tipping the crane. For
crawler cranes, do not attempt to raise or lower the boom
and jib from the ground or to the ground until the ends of
the crawlers are blocked, if required.
DANGER
Tipping Hazard!
Avoid death, serious injury, and tipping the crane. For the
truck crane, do not attempt to raise or lower the boom and
jib from the ground or to the ground over the rear of the
carrier until the outriggers are fully extended and the
carrier is level.
WARNING
Falling Load Hazard!
Avoid death or serious injury. Do not attempt to lift two or
more inserts with the lifting lugs on one insert. Lifting lugs
may break, allowing the inserts to fall.
Lifting lugs on each insert are designed only for lifting that
insert.
