Installing Counterweight Tray
See Figure 4-62 for the following procedure:
NOTE: The counterweight tray must be installed with an
assist crane. Damage may occur if the tray is lifted
too high.
At the time of the counterweight tray installation:
• The crane’s rotating bed must be assembled to the
carbody.
• The crane must be completely off the rotating bed lifting
jacks and must be supported by the crawlers.
• Rotating bed jacking cylinders in the stored position
• The live mast and the backhitch may be in the
installation position or in a raised position. If in a raised
position, then the live mast must be rotated to a 110°
angle (minimum) from its shipping position.
For ease of counterweight tray handling and lifting,
Manitowoc provides four pendants (2) and two plates (1).
The pendants and plates are stored in the counterweight
tray.
1. Position the trailer carrying the counterweight tray along
the desired side of the crane.
2. Attach the pendants (2) to the plates (1) and onto the
hook block.
3. Attach taglines to the supplied lugs for taglines (4) on
opposite sides of the counterweight tray (3).
Assistants will use the tag lines to help control the
movement of the counterweight tray and to help guide
the tray onto the rotating bed.
4. Lift the counterweight tray (3) from the trailer and
remove trailer.
WARNING
Falling Object Hazard!
The counterweight tray weighs approximately 20 000 kg
(44,000 lbs). Use the appropriate equipment and
techniques for lifting and transporting the counterweight
tray, otherwise it could fall, causing possible injury.
CAUTION
Parts Damage!
The alternate lifting rings (5) must be laying flat before
installing the counterweight tray onto the rotating bed or
damage will occur.
