Multi-purpose over-the-highway trailer arrangements

Claim 1

A low bed transporter vehicle arrangement adapted to be connected to a fifth wheel structure of an over-the-highway tractor comprising: a gooseneck structure having a horizontal beam structure and a vertical beam structure, king pin means on said horizontal beam structure and adapted to be connected to said fifth wheel structure, a first wheeled longitudinally extending and horizontally supporting frame structure spaced rearwardly of said gooseneck structure and having a forward portion, coupling means releasably connecting said first wheeled frame structure to said gooseneck structure, said coupling means including a first connecting portion on said gooseneck vertical beam and a second connecting portion on said forward portion of said first wheeled frame structure, said first and second connecting portions presenting abutting overlapping surface portions, lock means releasably coupling said overlapping surface portions to permit direct longitudinal separation in the same horizontal plane of said first wheeled frame structure and said gooseneck structure facilitating quick disconnect for changing and adding to the arrangement, a second wheeled longitudinally extending and horizontally supporting frame structure space rearwardly of said first wheel frame structure, interconnecting means releasably connecting said second wheeled frame structure to said first wheeled frame structure further facilitating quick disconnect for changing and adding to the arrangement, said interconnecting means including a second fifth wheel mounted on said first wheeled frame structure, and a load transport means connected with and extending between second fifth wheel of said first wheeled frame structure and said second wheeled frame structure, said second fifth wheel having a pivotal connection about a vertical axis with said load transport means, said interconnecting means further comprising a second gooseneck structure having a second horizontal beam structure and a second vertical beam structure, a second king pin means on said second horizontal beam structure engageable with said second fifth wheel, said second wheeled frame structure including a forward portion, said load transport means including a trailer platform having forward and rear portions, second coupling means releasably connecting said second vertical beam structure of said gooseneck structure to said forward portion of said trailer platform and third coupling means releasably connecting said rear portion of said trailer platform to said forward portion of said second wheeled frame structure, and, said second coupling and said third coupling means each including means for vertically adjusting the height of said platform relative to, said wheeled frames.
