PIVOTING BOOM HEAD
Boom Head Positions
The pivoting boom head can be positioned at the angles
given in View A, Figure 5-5 and operated within the specified
limitations.
Changing the Boom Head Position (without
Boom Extension)
Refer to Figure 5-5, View B for the following procedure.
1. Completely retract the boom sections and lower the
boom to its horizontal position.
2. Lower the hook block or the downhaul weight to the
ground to take the weight off of the hoist wire rope and
the boom head.
3. Remove the pivot lock pin (4).
4. Rotate the boom head so the desired hole in the boom
head, 0°, +40°, or +80°, is aligned with the pivot lock pin
holes.
5. Install and secure the pivot lock pin (4).
6. For the +80° position, remove and store the rope
retention pin (3) so the hoist wire rope is not kinked
against the pin.
7. Using the hoist control, raise the hook block or downhaul
weight off of the ground. Check that the hoist wire rope is
properly engaged with all the sheaves.
Changing the Boom Extension Offset
With the boom extension attached, it is necessary to raise or
lower both the boom extension and the boom head
simultaneously.
1. Completely retract the boom sections and lower the
boom to its horizontal position.
2. Lower the downhaul weight to the ground to take the
weight off of the hoist wire rope and the boom extension.
3. Attach adequate support to the end of the boom
extension. Use another crane or hoist to support the
boom extension.
4. With the boom extension supported, remove the pivot
lock pin (4). It will be necessary to remove the weight on
the pin in order to remove it.
5. Raise or lower the main boom until the desired offset
hole in the boom head (0°, -15°, or -30°) is aligned with
the pivot lock pin hole.
6. Install and secure the pivot lock pin (4).
7. Using the hoist control, raise the downhaul weight off of
the ground. Check that the hoist wire rope is properly
engaged with all the sheaves.
WARNING
Crushing Hazard!
The boom head is very heavy. Use another crane or hoist
to support the boom head so it cannot rotate freely when
the pivot lock pin is removed to change the offset angle.
Otherwise, serious injury or death may occur.
