3.7.
ANGLE RAMPS WITH RESPECT TO PLATFORMS, PORCHS, OR DECKS:
3.7.1.
There are situations where it is necessary to angle ramps with respect to a
platform, porch or deck. This can be done relatively easily, but the
components required are not normally included with a typical system unless it
is a ramp or ramp run without a platform. If a ramp must be angled when
attaching to a platform, an upper transition or lower transition with an MRST
(RAMP SUPPORT TOP) must be used instead of an MRHP (RAMP
HANGER PAIR). The same components can be used at the top and bottom of
ramp or ramp runs depending on the angle required.
3.7.2.
Angles up to approximately 4° can be accommodated using the upper
transition as long as the upper transition overlaps the surface of the platform,
porch or deck by at least 1” (FIG. 3.19).
3.7.3.
Angles up to approximately 8° can be accommodated using the lower
transition with a MRST (RAMP SUPPORT TOP). Refer to the appropriate
sections in OPTIONAL EQUIPMENT for installing the lower transtition and top
support. Like the upper transition, the lower transition should overlap the
surface of the platform, porch or deck by at least 1”, regardless of the angle
required (FIG. 3.20).
