TRACKS
Track Alignment
It is important that the Tracks are aligned with each other to ensure
that the Track Lugs on both Tracks contact a stair nose at the same
time.
Incorrectly aligned Tracks can cause Evacu-Trac to descend a
stairway at an angle, reducing stability.
To check alignment, line up a specific point on one Track (e.g. the tip
of a lug) with a specific point on the Evacu-Trac frame. Ensure that
the same point on the opposite Track is aligned with the same
reference point on the opposite side of the frame.
To adjust alignment, reposition one of the Tracks on the cog until the
tracks are correctly aligned. To do this you will need to loosen the
Tracks. See Track Tension Adjustment on Page 11. Note that you
may have to try re-positioning the Track a few times to find a location
that provides correct alignment.
After adjusting Track alignment, be sure to adjust Track tension to
achieve the correct descent speed. See Track Tension Adjustment
on Page 11.
Track Tension Factory Setting
Evacu-Trac is shipped from the factory with the Track tension
adjusted to accommodate passengers weighing 90 to 120 kg (200 to
265 lbs). This was done using a special machine to electronically
measure the total speed control force of the Governor and Tracks.
