1. Retaining clips
After the sections have been aligned and bolted
together, on each shipping split section remove the
bolt holding the splice plate to the breaker lifting
device runner. Retain the splice plate and remove
the remaining bolts, Fig. 4.32, and reinstall bolts
with splice plates in place. Fig. 4.34 shows a typical
breaker lifting device 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 breaker lifting device 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 breaker lifting device over the assembled
shipping split to check the alignment of the rail and
runner. If necessary, adjust the rail and/or runner
for smooth operation of the rollers on the breaker
lifting device. On seismic rated equipment, it is
necessary to remove the bracket locking the dolly
on the breaker lifting device before the device can
be used, Fig. 4.31. Replace the bracket after breaker
installation or removal is complete.
Outdoor equipment
When the breaker lifting device is provided with
outdoor equipment, it is shipped mounted and
secured in place. The shipping supports at either
end of the breaker lifting device movable track
must be removed. To free the 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.
