Ramp for elevating a tire for installing chains
View Patent ↗An improved ramp for facilitating the application of snow chains to the outer tire of a dual tire configuration of a semi truck, or other dual wheeled vehicle. The ramp has a front apron that is close to and parallel to the ground. The front apron allows for the tire to drive on to the apron without pushing the ramp out from under the tire. The tire then travels up an incline section to a top, supporting surface. The bottom of the ramp has a series of adjustable friction enhancing projections that increase friction between the bottom of the ramp and the ground. The friction enhancing projections are adjustable in length, allowing for a user to make the projections longer beneath the supporting surface, further facilitating driving the tire onto the ramp.
1. An improved commercial ramp for use in elevating a tire and wheel combination, said ramp comprising:
an elongate top platform configured for support thereon of a tire of a vehicle, said elongate top platform positioned on top of a body of said ramp, said elongate top platform having a horizontal surface relative to the ground and positioned on top of said body so as to support a tire above the ground;
a planar front apron extending from said body and parallel to said elongate top platform, an inclined edge forming a front edge of said body of said ramp, said inclined edge extending from said apron to said elongate top platform;
a plurality of adjustable friction enhancing projections extending from a bottom side of said ramp, said adjustable friction enhancing projections extending away from said lower surface and configured for adjustability in length each of said adjustable friction enhancing projections extends away from said bottom side of said ramp; and
wherein said ramp is configured for the tire to drive onto the apron, with the weight of the vehicle applied to the apron providing weight and increased friction between the ramp and a road surface below the ramp to prevent the ramp from being pushed by the tire away from the tire as the tire drives up the sloped ramp to the elongate top platform.
2. The improved commercial ramp of claim 1 wherein said friction enhancing projections comprise threaded bolts.
3. The improved commercial ramp of claim 1 wherein said friction enhancing projections comprise threaded hex bolts.
4. The improved commercial ramp of claim 1 wherein at least one of said apron, said incline edge, and said elongate top platform comprise a friction enhancing textured surface.
5. The improved commercial ramp of claim 4 wherein said friction enhancing textured surface comprises a metal grating.
6. The improved commercial ramp of claim 1 wherein a front edge of said apron is beveled to facilitate a tire rolling onto said apron.
7. The improved commercial ramp of claim 1 wherein said inclined edge is at a fifty to seventy degree incline from a top surface of said apron.
8. A method of using an improved commercial ramp to apply a snow chain assembly to an outer tire of a dual tire configuration, said method comprising: a step of providing the improved commercial ramp for use in elevating a tire and wheel combination, said improved commercial ramp comprising: an elongate top platform configured for support thereon of a tire of a vehicle, said elongate top platform positioned on top of a body of said ramp, said elongate top platform having a horizontal surface relative to the ground and positioned on top of said body so as to support a tire above the ground; a planar front apron extending from said body and parallel to said elongate top platform, an inclined edge forming a front edge of said body of said ramp, said inclined edge extending from said apron to said elongate top platform; a plurality of adjustable friction enhancing projections extending from a bottom side of said ramp, said adjustable friction enhancing projections extending away from said lower surface and configured for adjustability in length each of said adjustable friction enhancing projections extends away from said bottom side of said ramp; and wherein said ramp is configured for the tire to drive onto the apron, with the weight of the vehicle applied to the apron providing weight and increased friction between the ramp and a road surface below the ramp to prevent the ramp from being pushed by the tire away from the tire as the tire drives up a sloped portion of the ramp to the elongate top platform; a step of driving an inner tire of the dual tire configuration onto the apron, and up the inclined edge to the elongate top platform to freely suspend the outer tire of the dual tire configuration; a step of applying the snow chain assembly to the outer tire of the dual tire configuration; and a step of driving the inner tire back down off of the improved commercial ramp.
9. The method of claim 8 wherein said friction enhancing projections comprise threaded bolts.
10. The method of claim 8 wherein said friction enhancing projections comprise threaded hex bolts.
11. The method of claim 8 wherein at least one of said apron, said incline edge, and said elongate top platform comprise a friction enhancing textured surface.
12. The method of claim 8 wherein said friction enhancing textured surface comprises a metal grating.
13. The method of claim 8 wherein a front edge of said apron is beveled to facilitate a tire rolling onto said apron.
14. The method of claim 8 wherein said inclined edge is at a fifty to seventy degree incline from a top surface of said apron.
