摘要： A mating pair of portable metal ramps for use with pickup trucks, trailers and vans to load and unload small sized wheeled vehicles such as all terrain vehicles, riding lawn mowers, small tractors and motorcycles. The side beams of each ramp have a longitudinal groove into which the ends of three or more cross beams are recessed. The grooves sufficiently support and maintain the cross beams about the ramp that it is only necessary to weld the cross beam/side beam joints in those areas accessible from the underside of the ramp.

摘要： A foldable ramp apparatus. The ramp apparatus comprises a first and second ramp member. The first ramp includes a channel insert, and the second ramp includes an arcuate insert. The arcuate insert is configured to pivotally engage the channel insert. The arcuate insert has a curved apex that is adapted to be received within an elongated channel of the channel insert. A slotted segment is formed on a pair of legs that extends from the arcuate insert. A corresponding slotted segment formed on a pair of legs that extends from the channel insert. A cross-member is placed within the slotted segment interconnecting the pair of legs. In the preferred embodiment, the ramp apparatus further comprises a first lip formed on the arcuate portion and configured to engage an underside of the first leg and the second leg of the first ramp as well as the slotted segment. A second lip may be formed on the grooved portion and configured to engage an underside of the first leg and the second leg of the second ramp. Additionally, a first ledge is formed on the arcuate insert and a second ledge is formed on the channel insert, with the first and second ledge being operatively inserted into the slotted segment to attach the legs to the arcuate and channel insert.

摘要翻译： 折叠斜坡装置。 坡道装置包括第一和第二斜坡构件。 第一斜坡包括通道插入件，并且第二斜坡包括弧形插入件。 弧形插入件构造成枢转地接合通道插入件。 弧形插入件具有弯曲的顶点，其适于被容纳在通道插入件的细长通道内。 开槽段形成在从弓形插入件延伸的一对腿上。 形成在从通道插入件延伸的一对支腿上的对应的开槽段。 交叉构件放置在相互连接的一对腿的开槽段内。 在优选实施例中，斜坡装置还包括形成在弧形部分上并被配置为接合第一腿部的下侧和第一斜坡的第二腿部以及开槽部分的第一唇缘。 第二唇缘可以形成在凹槽部分上并且构造成接合第一腿部的下侧和第二斜坡的第二腿部。 此外，第一凸缘形成在弓形插入件上，并且第二凸缘形成在通道插入件上，其中第一和第二凸缘可操作地插入开槽段以将支腿附接到弓形和通道插入件。
