3.3.5. After the Support Leg is fully engaged in the foot, tighten the 3/8”-16 headless socket
setscrews to 15 ft.-lbs.(FIG 3.6)
Do not attempt to walk on the ramps until all Support Leg set screws have been
tightened as specified.
3.3.6. Tighten the foot thumb screw and insert 1-1/2” square plug into the top of the
Support Leg (FIG. 3.6).
3.3.7. Repeat the above procedure at all locations where ramps connect and at the ends of
a ramp or ramp run if a PRST – Ramp Support Top is used.
In situations where the lower end of a ramp or ramp run is too close to the
ground to install normal feet and feet are needed due to ground or other
conditions, special welded low profile feet (part no. PRLPRLP). are available
(FIG 3.7).
3.3.8. Remove the 5/16”-18 nylon insert locknuts and 5/16” flat washers attaching the
ramp handrail post (if already installed), position the low profile foot so the foot is
oriented under the ramp and the channel leg wraps around the ramp post. Reinstall
the locknuts and flat washers, adjust height as described below then tighten
fasteners securely. Repeat on the opposite side (FIG. 3.7).
FIG. 3.7
3.3.9. Adjust the ramp legs one at a time.
ADA guidelines call for a maximum slope of 1:12 (approximately 5°) and this is
the ideal slope for the PATHWAY 3G system. However, the ramps can be
installed from 1:14 to 1:8 (approximately 4° to 7°). Do not attempt to install the
ramps outside this range.
NOTE if the ramp is installed at the maximum angle (approximately 7°) longer
legs may be required.
3.3.9.1. Raise the ramp sections (at the center saddle bracket) to take any
sag out of the ramp run, then tighten the two locknuts in each
leg.
Adjusting sections can be accomplished by having someone sight down the
ramp while another person adjusts the ramp height.
It’s important to ensure that the ramp sections are parallel to each other. If
they are not, it may be difficult to install the handrails (FIG. 3.8).
3.3.9.2. Insert a plug into the top of each leg (FIG. 3.6).
