Installing the Folding Boom Extension
1. Before installing the boom extension make sure the
crane is set up on outriggers using normal setup
procedures. Refer to Setting the Outriggers, page 4-34.
NOTE: An auxiliary crane with sling is required to install
the boom extension.
2. Rotate the superstructure so the boom is over the rear.
3. Retract and lower the boom to horizontal.
4. Attach a tag line to the junction of the 35 ft and 23 ft
extensions.
5. Using a sling attached to an auxiliary crane, lift the
extension in front of the main boom (Figure 6-74).
6. Align the extension anchor fittings (1, Figure 6-75) to the
boom nose attachment fittings (2).
7. On both sides of the boom nose install the pins (3,
Figure 6-75) through the fittings using an impact driver
turning the jack screw counterclockwise.
8. Remove the sling from the boom extension.
To stow the entire 58 ft (17.7 m) folding extension on the
main boom, refer to the Stowing Procedure: 58 ft (17.7 m)
Extension, page 6-65.
To erect just the 35 ft (10.5 m) extension, refer to Stowing
Procedure: 23 ft (7 m) Boom Fly Extension, page 6-64.
To erect the 58 ft extension, continue with step 18., page 6-
