MLC165-1 OPERATOR MANUAL SETUP AND INSTALLATION
Install Carbody Counterweight (Series 2)
If your crane has the Series 2 counterweight package, install
the carbody counterweights as follows, before installing the
crane counterweights.
See Figure 4-28
for the following procedure.
1. Position the trailer carrying the carbody counterweight
(1) on the desired side of the crane.
2. Attach a 4-leg chain sling — or shackles and synthetic
slings — from the assist crane to the four lifting lugs on
the carbody counterweight. Each carbody counterweight
weighs approximately 22,488 lb (10 200 kg).
3. Lift the carbody counterweight clear of the trailer and
remove the trailer.
4. Rotate the carbody counterweight as required so the
slotted lugs on the counterweight face the carbody.
5. Position the carbody counterweight between the
crawlers at the cab end of the crane.
6. Lower the carbody counterweight so the slotted lugs on
the counterweight engage the hooked lugs on the
carbody.
7. Continue to lower the counterweight until the lifting
slings go slack.
8. Remove the two pins (3) from the storage lugs (4) on the
carbody counterweight.
9. Install the two pins (3) in the hooked lugs to secure the
carbody counterweight to the carbody.
10. Disconnect the lifting slings.
11. If necessary, hook the crawler step (2) onto the
counterweight bar, and install the wire-lock pins (6).
12. Swing 180° and repeat the process for the other carbody
counterweight.
DANGER
Tipping Hazard!
To prevent tipping or structural failure of components:
• Install the carbody counterweight before installing the
crane counterweight.
