Liberty Series™ Ramp Installation Guide-Revision 8/1/2020

14. Grade Variations

Changes to upgrade and downgrade can affect the amount of ramping needed for a safe layout,
while a significant cross slope can impact the leg lengths needed for the ramp to be level across its
width.

Calculating grade variations are an important part of the evaluation.

UPGRADE



upward slope of the ground

DOWNGRADE



downward slope of the ground

CROSS SLOPE



change in slope that runs

across the width of the ramp
