Legend for Figure 4-61
Moving the Equalizer to the Equalizer Rails
See Figure 4-61 for the following procedure.
1. If stored, remove the rear stop pins (1, View E) from the
rear storage tubes (2) and install the pins in the rear
holes of the rails (3).
If equipped with rollers (1A, View E-E) install the rollers
over the rear stop pins as the pins are installed. The
rollers are stored in the parts box.
2. Leave the front stop pins (1, View D) stored in the front
storage lugs (2).
3. Pay out the mast hoist wire rope to lower the masts (4
and 5, View B).
4. At the same time, haul in the boom hoist wire rope to
raise the equalizer (6).
5. Stop lowering the masts when the fixed mast (5, View B)
is at 39.7°.
6. Connect two SL 6 slings (8, View A) from the hook of the
assist crane (9) and to the front two lifting lugs (10) on
the equalizer (6).
7. Slowly lift the equalizer with the assist crane until the
equalizer is horizontal as shown in View A.
8. Slowly pay out the boom hoist wire rope from the
MLC650 and lower the equalizer (6) with the assist
crane until the equalizer is resting on the rails (3, View
C).
9. Make sure the equalizer is on the forward side of the
rear stop pins (1, View D).
10. Slacken the boom hoist wire rope and the SL 6 slings so
the equalizer cannot slide rearward.
11. Remove the front stop pins (1, View E) from the front
storage tubes (2) and install the pins in the front holes of
the rails (3, View D) and the equalizer (6).
12. Disconnect the SL 6 slings (8, View A) from the
