7. OPTIONAL EQUIPMENT
7.1. RAMP SUPPORT TOP
The PRST (RAMP SUPPORT TOP) provides supplemental support at the upper (or lower) end of the ramp.
When used, the PRST (RAMP SUPPORT TOP) replaces the PRHBPR (RAMP HANDRAIL END BRACKET PAIR).
7.1.1. Attach top support brackets with two 5/16”-18 x 1-1/2” hex bolts and two 5/16” flat
washers (FIG. 7.1).
There is a “left” and “right” top support bracket, but they can be installed on either
side of the ramp depending on whether they are used at the upper or lower end of
the ramp or ramp run. The two longer studs must be oriented toward the end of the
ramp regardless of the side where they are being installed.
7.1.2. If used with a transition plate (upper or lower), the following steps are completed after
the ramp is resting on a supporting surface and transition plate is installed.
7.1.3. Install and level Support Leg Brackets on the two shorter studs of the top support bracket
in the same manner described in SECTION 3.3 (FIG. 7.2).
7.1.4. Locate the appropriate PSLxxPR (SUPPORT LEG PAIR where xx denotes the leg length) for
the location and install it in the same manner described in SECTION 3.3 (FIG. 7.2).
If installing on soft soil, it may be necessary to set the foot on a concrete pad.
7.1.5. Insert plugs into tops of the ramp legs.
7.1.6. Refer to previous sections for anchoring upper and lower transitions.
