noted in item 6 below. Load the 3,000 lb tray plate onto
the counterweight platform first and then the remaining
plates on top of it.
2. The two 10,000 lb counterweight plates must be rigged
with the 3000 lb counterweight tray plate. They must be
rigged on top of the 3000 lb tray plate and under the
3000 lb and two 5000 lb counterweight plates.
3. The 2,250 lb and 4,000 lb winged counterweights can
only be attached to the 3,000 lb or the two 5,000 lb
plates. The wing counterweights can only be attached to
the plate that is on top of the assembly. The wing
counterweights can not be attached to the lower plates
in the assembly. The winged counterweights require a
notch cut-out for rigging, only the 3,000 lb and 5,000 lb
plates have this cut out.
4. The two 10,000 lb counterweight plates must be rigged
with the 3000 lb tray plate.
5. The 3,000 lb and two 5,000 lb counterweight plates can
be secured to the turntable. To do this, assemble the
3,000 lb counterweight plate, the two 5,000 lb
counterweight plates, the two 10,000 lb counterweight
plates, and the 3,000 lb counterweight tray onto the
counterweight platform according to Figure 6-19. Move
the turntable into position and raise the counterweight
assembly with the counterweight hoisting unit. Secure
the top counterweight plate (3,000 lb or 5,000 lb) to the
turntable with the two bolt pins (1, Figure 6-26). Place
the bolt pins through the two mounting brackets (2,
Figure 6-26) and rotate the role pins (3, Figure 6-26) into
the slots on the mounting bracket. Ensure all the locking
pins (4) are in the locked position as shown in
Figure 6-25.
DO NOT install the two bolt pins while any of the 4,000 lb or
2,250 lb wing counterweights are rigged to the crane.
Counterweight hoist unit
The counterweight hoist unit consists of two lifting cylinders
which are attached to the turntable.
The lifting cylinders raise the 3,000 lb tray plate and the
assembled counterweights into position on the turntable.
When the counterweight plates are ready to be removed
from the turntable the lifting cylinders lower the
counterweights back onto the crane counterweight platform.
The lifting cylinders (1, Figure 6-27) can be extended and
retracted.
To lift and lower the counterweight, the lifting cylinders are
rotated into the posts on the 3000 lb counterweight tray.

ensure the two bolt pins (Figure 6-19) are stowed in a

while any of the left and right wing counterweights are
rigged to the crane.
WARNING
Crush Hazard!
Before lifting the 3,000 lb tray plate, remove all objects
from the top counterweight section which could be
crushed.
Be sure that no person is on the counterweight platform
