2250 OPERATOR MANUAL SETUP AND INSTALLATION
Connect Equalizer to Boom Butt
NOTE: The circled numbers in Figure 4-14 correspond to
the numbers of the following steps.
1. Reeve the load line from the top of the rear or right rear
drum under the small sheave on the boom butt. Place
the retaining pins into the sheave (see View A).
2. Anchor the load line to the equalizer using a dead-end
socket and wedge (see View B).
3. Slowly pay out the boom hoist line and haul in the load
line to pull the equalizer out of the tie-down clips on the
gantry (see View C).
4. Continue until the equalizer is about 0,3 m (1 ft) out of
the clips and is clear of the guide rollers.
5. Raise the gantry to the limit of the gantry cylinders.
NOTE: Make sure the equalizer does not go back into the
clips as the gantry rises. Pay out the boom hoist
line as needed.
6. Raise the boom butt to the limit of the boom butt cylinder.
7. Haul in the load line to lift the equalizer off the gantry.
Pay out the boom hoist line at the same time.
8. Maintain equal haul-in and payout speeds so that the
equalizer rises smoothly.
a. Too much tension in either line will cause the butt to
rise off the cylinder and the equalizer to stop.
b. Too little tension will cause the equalizer to tip.
