The rails are erected on the spot, with end stops at both ends
of travel. Rail overall assembled length will depend upon travel
orientation - either front to back or side to side. The truck’s grooved
wheels sit on the rails and help to keep the truck on the rails during
movement.
5.14.1.2 VT Low Lift Truck
The alternate configuration, the “Low Lift” truck, is used on
installations where the room ceiling is too low for the High Lift
Truck. In that case, the High Lift Truck is modified into the Low Lift
configuration. See Figure 110 .
VT Truck rails are installed at the rear of the gear lineup, for side to
side travel. Rail sections can be added to extend the truck travel to
any needed length for target vertical section access. See
Figure
111 .
The rails are aligned with the front and rear walls of the VT
compartment. The Low Lift Truck is mounted on the rails, and a VT
is winched from floor level to just above the VT compartment floor
height. The truck is then trolleyed along the rails to the target vertical
section VT compartment, and the VT is lowered into place using the
truck winch.
Installing the fused main bus VTs requires a special tool (see 5.13.4
for details.)

m WARNING
PROPER OPERATION OF THE LIFTING TRUCK REQUIRES ATTENTION TO
PROPER ALIGNMENT OF THE TRUCK WHEELS ON THE MOUNTED RAILS.
CARE MUST BE TAKEN TO MOVE THE TRUCK SLOWLY ON ITS RAILS, TO
AVOID LOAD SWINGS DURING LIFTING, TRANSPORT OR LOWERING, AND
TO PROPERLY STOP THE TRUCK AT THE RAIL END STOPS.
