After the sections have been aligned and bolted together, on each
shipping split section remove the bolt holding the splice plate to the
hoist runner. Retain the splice plate and remove the remaining
bolts, fig. 4-32 (2), and reinstall bolts with splice plates in place.
Figure 4.34 shows a typical hoist rail splice installed.

On the runner, there is also a splice plate held in place with two
screws, fig. 4-33 shows a typical example. After the hoist rail splices
have been installed, remove and retain the two screws holding the
runner splice. Remove the two screws that are on the other side of
the shipping split. Place the runner splice over both sections of the
shipping split and align the four mounting holes. Install the four
screws that were previously removed.

After the splice plates have been installed, run the hoist carriage
over the assembled shipping split to check the alignment of the
hoist rail and runner. If necessary, adjust the rail and/or runner for
smooth operation of the rollers on the hoist carriage.

On seismic rated equipment, it is necessary to remove the bracket
locking the hoist dolly on the carriage before the hoist can be used,
Fig. 4-31. Replace the bracket after breaker installation or removal
is complete.

Outdoor Equipment

When the hoist is provided with outdoor equipment, it is shipped
mounted and secured in place. The shipping supports at either end
of the hoist movable track must be removed. To free the hoist dolly,
remove the retaining clip used to keep it in place during shipment,
as shown in Fig. 4-35.

Final Inspection

Make a final inspection to see that no tools, construction materials,
or other foreign matter have been left in the switchgear equipment.
