ABSTRACT:
A first anti-slip ramp pad has a resilient base with a plurality of elongated, raised leg grips disposed thereon in parallel, spaced-apart relation for engaging and holding the inclined ramp legs of an automobile service ramp. The base of this first anti-slip ramp pad also includes an elongated tire gripper section having a plurality of raised gripper nodules that extends outward from the ramp, so that an advancing tire will roll over the elongated tire gripper section, holding the pad and the ramp as the tire begins to travel up the automobile service ramp. A second anti-slip ramp pad similar to the first ramp pad also having a plurality of elongated, raised leg grips may be placed under the rear legs of the automobile ramp to increase the frictional engagement with the floor and further reduce the chances of ramp slippage.
