ABSTRACT:
A trailer including a longitudinally extending frame comprised of longitudinally extending frame members having rearward and forward ends. Each of the frame members has a first section modulus which is positioned forwardly of the rearward end thereof, at least a second section modulus which is positioned forwardly of the first section modulus, and a transition section modulus positioned therebetween. A running gear is longitudinally slidably mounted on the frame members and has running gear retainers mounted thereon which slidably embrace the lower end of the frame members. When the running gear is in its transport position, a spacer is provided between the running gear retainers and the frame members to prevent excessive play therebetween. The retainers are designed so that once the retainers move out of engagement with the spacers, there is sufficient play or gap between the retainers and the frame members to enable the running gear to move from the first section modulus to the second section modulus. The varying of the section modulus on the frame members enables the trailer to accommodate heavy loads without increasing the deck height or affecting the tilt angle thereof.
