Install Hook-and-Weight Ball
See Figure 4-11.
1. Position the trailer (1, View B) carrying the hook-and-
weight ball (2) under the boom butt.
2. If necessary, route the load line (3, View B) from Drum 1
(front drum only) over the guide sheaves (4) in the
boom butt.
OR — if the load line (3A, View B) is already stored in
the boom butt — unpin the button socket (5A, View B)
from the hole in the front of the rotating bed.
3. Connect the button socket (5, View A) to the button on
the end of the load line. See Anchoring Wire Rope to
Button Socket on page 4-93.
The button socket is stored in the parts box supplied with
the crane.
4. Connect the button socket (5, View A) to the lug on the
hook-and-weight ball (2).
5. Verify that the wire rope is spooled properly on the boom
hoist drum.
6. Raise the boom butt and remove the trailer.
Unload Trailers
The crane can now be used to unload the trailers as shown
in Figure 4-12
, View A.
Refer to the Liftcrane Boom Butt Capacities at the end of this
section for lifting capacities.
Boom Sections
All boom sections have lifting lugs as shown in Figure 4-12.
• Handle the boom sections with care to avoid damaging
the lacings and chords.
• Use synthetic lifting slings (7) (crane owner furnished) to
lift the boom sections. If wire rope or chain slings are
used to handle the boom sections, install protective
covering (such as sections of rubber tire) between the
slings and the section being lifted.
Jib Sections
The jib sections do not have lifting lugs.
• Handle the jib sections with care to avoid damaging the
lacings and chords.
• Use synthetic lifting slings (crane owner furnished) to
handle the jib sections. Lift at the chords only. Never lift
at the lacings. If wire rope or chain slings are used to
handle the jib sections, install protective covering (such
as sections of rubber tire) between the slings and the
section being lifted.
• See Figure 4-13
for the center of gravity of the jib
sections.
Counterweight
• Each crane counterweight box has two lifting points.
• The crane counterweight tray and each carbody
counterweight has three lifting lugs.
Use the Manitowoc supplied chain lifting sling (Figure 4-2 on
page 4-3) to handle the crane and carbody counterweight
boxes and tray.
CAUTION
Wire Rope Damage!
Observe the load line spooling on Drum 1 often during
crane assembly.
To avoid wire rope damage, adjust the load line spooling
as necessary.
WARNING
Falling Load Hazard!
The lifting lugs on each boom section are designed only
for lifting that section. Do not attempt to lift two or more
boom sections with the lifting lugs on one section. The
lifting lugs may break allowing the boom sections to fall.
