REMOVABLE COUNTERWEIGHT
•
The 5443 kg (12,000 lb) removable counterweight
consists of three slabs, each weighing 1814 kg (4000
lb).
•
The 8165 kg (18,000 lb) removable counterweight
consists of three slabs each weighing 1814 kg (4000 lb)
and one slab weighing 2721 (6000 lb).
•
An optional 10,885 kg (24,000 lb) removable
counterweight consists of two 1,360 kg (3000 lb) “wing
weights” that hang on the existing 8,165 kg (18,000 lb)
counterweight stack.
NOTE:
This extra counterweight is not roadable due to the
overall width of the machine when installed, but you
c a n m o v e a r ou n d t h e j o b s i t e w i th t h e f u l l
counterweight installed.
The following procedures are applicable for
removal and installation of any or all pieces
Figure 4-9.
The counterweight contains lugs for attachment to the
removal cylinders and lugs to pin it under the hoist mounting.
The additional slabs pin the structure to each other. The
counterweights can be pinned to the carrier deck and are
transferred between the turntable and the carrier deck by two
hydraulic removal cylinders. The cylinders are controlled
from a valve assembly located under the hoist mounting. The
valve contains an inlet section, an outlet section with relief
valve, and a working section for each cylinder. The valve is
electrically controlled by the switch panel on the right side of
the turntable.
Mounting the Counterweight
1.
Position the crane on a firm level surface. Fully extend
and set the outriggers.
2.
Rotate and align the rear of the superstructure above the
removable counterweight stowed on the carrier deck.
Engaging the pin type turntable lock will aid alignment.
NOTE:
The crane function switch must be OFF before
using the counterweight switch panel.
3.
Using the counterweight switch panel (Figure 4-8), lower
the counterweight cylinders by pushing on a power/
enable button while pushing the appropriate cylinder
lower button. Pin the cylinders to the counterweight
using the attach pins in the cylinders. Insert the retaining
pins in the attach pins.
4.
Push in, turn, and remove the long attach pins from the
counterweight and carrier frame lugs.
5.
Using the switch panel, raise the counterweight up
under the superstructure frame.
NOTE:
It may be necessary to jog the counterweight
switch(es) (Figure 4-9) to install the upper attach
pins.
6.
Remove the upper attach pins from the stowage
bushings and install them into the upper counterweight
and superstructure frame lugs.
7.
Push in on the pins and turn to lock pin in the notch.
8.
Insert the long pins into the bottom of the counterweight.
Push in on the pins and turn to lock pin in the notch.
9.
The crane is now ready for operation with the
counterweight installed.
.
Stowing the Counterweight
1.
Position the crane on a firm level surface. Fully extend
and set the outriggers.
2.
Rotate the superstructure to align the counterweight with
the stowage area. Engaging the pin type turntable lock
will aid alignment.
NOTE:
It may be necessary to jog the counterweight using
the switch(es) to remove the weight of the
counterweight from the upper attach pins.
3.
Using the counterweight switch panel, raise the
counterweight cylinders to relieve weight on the upper
attach pins. Push in, turn, and remove the upper attach
pins from the superstructure frame lugs and the
counterweight
DANGER
Ensure that all mounting pins are properly installed and
locked, during, and after operating the counterweight
removal system.
