ABSTRACT:
A log carrying trailer chassis especially constructed to withstand the compressive and shear loads exerted on a trailer chassis while also being lighter in weight, thereby increasing the payload to be carried. The chassis assembly comprises a chassis frame having a central body portion, two laterally spaced-apart legs depending from the central body portion, and two shoulder portions located at the top of the body portion directly above the leg portion. The chassis is constructed without the use of a bridge beam common to the prior art chassis, and the reach tube is contructed with opposing sides offset 45.degree. from the horizontal and vertical axes. The primary load bearing member is a rotary thrust bearing centrally mounted on top of the central body portion, so that the weight of the log load is transmitted downwardly through the center of the chassis through plate support means mounted in the central body portion beneath the rotary thrust bearing, and then to the wheels.
