racks.6 Petitioner currently uses 10 transtackers in the Reserve
Facility.
Each transtacker has a mast approximately 50 feet high,
which guides the portion of the transtacker that carries the
operator and load as it moves up and down from the bottom to the
top of the racks. At the top of the mast, two wheels follow a
guide tube, which is mounted on a tie that spans the aisle and
that is attached to the racks on each side of the aisle. At the
bottom, the transtacker is guided by a steel channel or track
that is anchored to the floor by bolts in the center of the
aisle. The transtacker has lateral wheels that engage a flared
steel guide to lead the transtacker onto the track when the
operator directs it into an aisle from the south clear area. The
transtackers automatically slow down near the ends of the aisles
and must be at ground level before a transtacker leaves an aisle.
The transtackers can operate in the south clear area only when
the cab is at floor level, since the mast is unstable without the
guide rails.
The transtackers are powered by a dedicated electrical
system installed at the top of each aisle. The top of the
transtacker mast carries four trolleylike "bus bar" contacts that
draw electrical power from conductors mounted adjacent to the
guide tube. Outside of the aisles, in the clear area at the
6Respondent has allowed petitioner an ITC for the
transtackers, and those credits are not in issue in this case.
