Abstract
Abstract A main ramp member, having a first end and a top surface, is provided with two base members telescopingly mounted for transverse movement at either side thereof and means for mounting the first end to a trailer for rotation of the main ramp member between a loading position and a transporting position. Each of two receiving ramp members has a first end pivotally mounted proximate to the first end of the main ramp member to a corresponding base member below the plane of the top surface thereof. When the main ramp member is in its loading position, each receiving ramp member is elevated above the base member by a foot member which contacts the ground. When the main ramp member is in its transporting position, each base member supports the receiving ramp member mounted thereto below the plane of the top surface of the main ramp member. Bars are provided which cooperate with the receiving ramp members to form two wheel receptacles in which the rear wheels of wheel mounted machinery are disposed and thereby restrained against rotation when the main ramp member is in its transporting position.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
193 words
A ramp for use with a trailer of the type used to transport wheel mounted machinery, the ramp comprising: a main ramp member having a first end and a top surface and including load bearing means and means for mounting said first end to the trailer for rotation of said main ramp member between a loading position and a transporting position; receiving ramp means for receiving thereon a wheel of the machinery to be transported, said receiving ramp means having a first end pivotally mounted to said main ramp member below the plane of said top surface and proximate to said first end of said main ramp member and a foot member for contacting the ground to support said receiving ramp means when said main ramp member is in said loading position, wherein said receiving ramp means is supported below the plane of said top surface by said load bearing means when said main ramp member is in said transporting position; and restraining means cooperating with said receiving ramp means to form a wheel receptacle for restraining the wheel received thereon against rotation when said main ramp member is in said transporting position.
Claim 2
Dependent Claim
193 words
A ramp for use with a trailer of the type used to transport wheel mounted machinery, the ramp comprising: a main ramp member having a first end and a top surface and including load bearing means and means for mounting said first end to the trailer for rotation of said main ramp member between a loading position and a transporting position; receiving ramp means for receiving thereon a wheel of the machinery to be transported, said receiving ramp means having a first end pivotally mounted to said main ramp member below the plane of said top surface and proximate to said first end of said main ramp member and a foot member for contacting the ground to support said receiving ramp means when said main ramp member is in said loading position, wherein said receiving ramp means is supported below the plane of said top surface by said load bearing means when said main ramp member is in said transporting position; and restraining means cooperating with said receiving ramp means to form a wheel receptacle for restraining the wheel received thereon against rotation when said main ramp member is in said transporting position.
Claim 3
Dependent Claim
41 words
The ramp recited in claim 1 wherein said main ramp member further includes a base member having a top surface comprising said load bearing means, wherein said first end of said receiving ramp means is pivotally mounted to said base member.
Claim 4
Dependent Claim
29 words
The ramp recited in claim 2 wherein said base member includes a base portion for contacting the ground to support said main ramp member when in said loading position.
Claim 5
Dependent Claim
30 words
The ramp recited in claim 1 wherein said foot member includes a plurality of downwardly depending links mounted to said receiving ramp means and a skid mounted to said links.
Claim 6
Dependent Claim
172 words
The ramp recited in claim 1 wherein: said load bearing means comprises two load bearing surfaces disposed at opposite sides of said main ramp member; said receiving ramp means comprises two receiving ramp members each for receiving thereon one wheel of the machinery to be transported, each said receiving ramp member having a first end pivotally mounted at opposite sides of said main ramp member below the plane of the top surface and proximate to said first end of said main ramp member and a foot member for contacting the ground to support said receiving ramp member when said main ramp member is in said loading position, wherein each said receiving ramp member is supported below the plane of said top surface by a corresponding load bearing surface when said main ramp member is in said transporting position; and said restraining mEans cooperate with each said receiving ramp member to form two wheels receptacles for restraining the wheels received thereon against rotation when said main ramp member is in said transporting position.
Claim 7
Dependent Claim
27 words
The ramp recited in claim 5 further including two folding members pivotally each mounted to opposite sides of said main ramp members proximate said second end thereof.
Claim 8
Dependent Claim
60 words
The ramp recited in claim 5 wherein said main ramp member further includes two base members each having a top surface comprising a corresponding load bearing surface, wherein said base members are mounted for transverse movement relative to said main ramp member and said first end of each said receiving ramp member is pivotally mounted to a corresponding base member.
Claim 9
Dependent Claim
120 words
The ramp recited in claim 5 wherein: said main ramp member further includes front and rear square channel beams extending transversely thereof, wherein said front square channel beam has two front bars telescopingly mounted to opposite ends thereof and said rear square channel beam has two rear bars telescopingly mounted in opposite ends thereof, and two panels each pivotally mounted between corresponding pairs of said front and rear bars, wherein said panels are movable between a first position in which said panels form a portion of said top surface and a second position in which said bars are telescoped outwardly and said panels are pivoted upwardly and outwardly; and said pairs of front and rear bars comprise said restraining means.
Claim 10
Dependent Claim
58 words
The ramp recited in claim 8 wherein said main ramp member further includes two base members each having a top surface comprising a corresponding load bearing surface, wherein said base members are removably mounted to said main ramp member and said first end of each of said receiving ramp member is pivotally mounted to a corresponding base member.
Claim 11
Dependent Claim
129 words
The ramp recited in claim 9 further including: two auxiliary panels each pivotally mounted between corresponding pairs of said front and rear bars, wherein said auxiliary panels are movable between a raised position and a lowered position in which said auxiliary said second pivoted downwardly and outwardly; and two folding members each pivotally mounted to opposite sides of said main ramp member proximate to sai dsecond end thereof, wherein said folding members are movable between an inward position in which said folding members rest on said top surface of said main ramp member and an outward position in which, when said first-mentioned panels are in said first position, said folding members cooperate with said auxiliary panels, when said auxiliary members are in said lowered position, to widen the ramp.
Claim 12
Dependent Claim
