MLC650 OPERATOR MANUAL SET-UP AND INSTALLATION
Lowering Rotating Bed Jacking Cylinders
See Figure 4-154 for the following procedure:
NOTE: A minimum trailer height of 1168 mm (46 in) is
necessary to be able to completely retract the
rotating bed jacking cylinders.
1. Using the remote control, lower the rotating bed until it is
resting on the trailer.
NOTE: The rotating bed beam (11) should be very close to
the drop deck.
2. Remove the U-shaped locking pin (2, View A).
3. Retract the rotating bed jacking cylinders (1) completely.
4. Place the U-shaped locking pin back on the outrigger
pad.
5. Place the outrigger pad in the stored position, aligning
the lug on the rotating bed with the hole on the outrigger
pad. Install the outrigger pad locking pin (10, View B).
NOTE: The outrigger pad weighs 30 kg (65 lb).
For shipping, all four outrigger pads should be
stored on the rotating bed so the pads are available
when the crane arrives at the new job site.
6. Remove the locking pin (9, View A) from the outrigger
beam assembly.
7. Remove the jacking cylinder pin (8, View A).
8. Using the remote control, raise the outrigger jacking
assembly and secure with the jacking cylinder pin (8,
View B).
9. Remove the pins and safety pins from the outrigger
struts (6, View A) and place the outrigger struts (6, View
B) in the stored position.
10. Swing the outrigger beam assembly (7, View B) toward
the rotating bed to the stored position.
11. Secure the outrigger beam assembly to the rotating bed
lug (5, View B) with the outrigger pins and safety pins.
12. Repeat steps 2–11 for each rotating bed jacking
assembly.
13. Secure the rotating bed to the trailer for shipping.
