3 . The ramp assembly of claim 2 wherein the first platform side assembly includes at least one support structure to provide a beam strength to the ramp assembly.
4 . The ramp assembly of claim 3 wherein the at least one support structure defines a tube.
5 . The ramp assembly of claim 2 wherein the first platform side assembly includes a first bottom support structure and a second bottom support structure spaced from the first bottom support structure, wherein the first roller track is located between the first bottom support structure and the second bottom support structure.
6 . The ramp assembly of claim 5 wherein one or more of the first bottom support structure and the second bottom support structure defines a channel.
7 . The ramp assembly of claim 5 wherein the first bottom support structure includes a first sidewall having a bottom portion and a top portion, wherein the first sidewall extends from the bottom portion beneath the first track section and extends to the top portion above the first track section.
8 . The ramp assembly of claim 7 wherein the top portion of the first sidewall defines a first slot with a first top sidewall, wherein the first slot is configured to receive a first siderail.
9 . The ramp assembly of claim 8 wherein the first siderail includes a first bar rotatably supported by a plurality of first legs, wherein each of the plurality of first the legs is rotatably coupled to the first sidewall and the first siderail includes a lowered position in the first slot and a raised position extended from the first slot.
10 . The ramp assembly of claim 9 wherein the first bar comprises a channel and wherein at least one of the first legs nests within the channel when the first siderail is in the lowered position.
11 . The ramp assembly of claim 10 wherein the first slot is defined by a pair of sidewalls and wherein the plurality of leg links are received between and pivotably secured to the pair of sidewalls.
12 . The ramp assembly of claim 11 , wherein a top of the first siderail is disposed approximately at or below a top edge of the pair of sidewalls.
13 . The ramp assembly of claim 1 wherein the first platform side assembly and the second platform side assembly include respectively an extruded first side part and an extruded second side part.
14 . The ramp assembly of claim 13 wherein the extruded first side part and extruded second side part are interchangeable.
15 . The ramp assembly of claim 1 wherein the first platform side assembly and the second side assembly include respectively a first siderail assembly and a second siderail assembly.
16 . The ramp assembly of claim 15 wherein the first siderail assembly and second siderail assembly are interchangeable.
17 . The ramp assembly of any claim 1 further comprising a chassis pivotally coupled to a trailing edge of the ramp platform and movable along a length of a guide rail assembly.
18 . The ramp assembly of claim 17 wherein the guide rail assembly is disposed between a left side and a right side of the ramp platform.
19 . The ramp assembly of claim 17 wherein the guide rail assembly is disposed below the ramp platform.
20 . A first ramp assembly and a second ramp assembly of claim 1 , wherein: the platform base of the first ramp assembly has a different width than the platform base of the second ramp assembly; and a first set of the first and second platform side assemblies are interchangeable with a second set of the first and second platform side assemblies.
