Abstract
A portable curb ramp (1) for wheeled vehicles and equipment (4) having a curb conforming contact surface (7) and a planar road contact surface (6) on an underside and a sloping top surface (5) to allow tires (3) to transverse from a road surface up and over a curb (2). The sloping top surface (5) may have a plurality of transverse ridges (8) for improved traction. The underside curb conforming contact surface (7) may have a lip which extends over the top of the curb and one or more ridges (9) on the planar contact surface to reduce slippage of the ramp on a road surface. Magnets (13) attached to the planar contact surface allows the ramp to be secured to metal surfaces (14) on the wheeled vehicle and equipment so the ramp is readily accessible. The curb conforming contact surface (7) may have two low bearing side walls (16) with a hollow cutout (12) in between in order to reduce the weight of the ramp.
