SWINGAWAY BOOM EXTENSION

m (26 to 45 ft) telescoping, 0 or 30 degrees offsetable

The boom extension mounts directly to the boom nose

and the telescoping swingaway weighs approximately 810
kg (1790 lb).
Maintenance
Removal
NOTE: If an adequate lifting device is available, the
swingaway boom extension can be dismounted
directly from the side
1. Fully extend and set the outriggers and level the crane.
2. Position the boom over the front.
3. If extended, fully retract all the boom sections and lower
the boom to minimum elevation to permit ease of
installation of pins and access to the boom nose.
NOTE: The auxiliary boom nose (rooster sheave) does not
have to be removed. However, if reeved, the hoist
cable must be removed from the sheave.
4. On the rear stowage bracket, remove the retainer pin
securing the sliding support in the “IN” position
(Figure 4-36). Pull out on the handle to pull the
swingaway away from the rear of the boom and engage
the swingaway anchor fittings with the boom nose
attachment lugs. Install the retainer pin securing the
sliding support in the “OUT” position.
5. Remove the clip pins from the two right side attachment
pins stowed in the base of the swingaway and remove
the two attachment pins from the swingaway. Insert the
two right side attachment pins through the right side
boom attachment and swingaway anchor fittings. Install
the clip pins in the attachment pins.
6. Remove the clip pins from the hitch pin that secures the
boom extension to the rear stowage bracket. Remove
the hitch pin, unlocking the boom extension from the
boom and stow in the stowage lug.
7. Attach a length of rope to the boom extension tip to aid in
swinging the boom extension into place ahead of the
boom nose.
8. Raise the boom to horizontal and extend the boom
approximately 51 to 64 cm (20 to 25 in). Make certain
that the boom extension stowage lugs clear the guide
pins and ramp on the front and rear stowage brackets.
9. Slightly raise and/or lower the boom to help control the
boom extension. Using the rope attached to the top of
the boom extension, manually swing the extension into
place ahead of the boom nose, engaging the attachment
fittings with the anchor fittings on the left side of the
boom nose.
