Figure 108
and
Figure 110
.
To install a top voltage transformer,
•
Choose a lift truck configuration that applies to the ceiling height.
•
Temporarily install lift truck rails at the top of the target vertical
section. The rail assembly has end stops to prevent the lift truck
from rolling back off of the rails.
•
Mount the lift truck (low lift or high lift) on to the rails.
•
Low lift truck: use the lift truck winch to raise a VT in its bracket to
the VT compartment floor height.
•
High lift truck: use the lift truck winch to raise a VT in its bracket
above the vertical section top.
•
Move the lift truck and VT over the rails until they are above the
destination VT compartment.
•
Lower the VT into the VT compartment.
