A log bunk assembly for use on logging truck-trailer units. The bunk comprises a generally horizontal bunk beam having a recess, hub-and-saucer assembly for allowing the bunk beam and trailer/log load to pivot in the horizontal plane, an upper trunnion saddle contained within the bunk beam recess, a lower trunnion saddle, and a trunnion tube attached to a pedestal mounted on the hub-and-saucer assembly. The trunnion tube is clamped between and frictionally engages the upper and lower trunnion saddles. The bunk beam pivots about the horizontal axis of the trunnion tube in the vertical plane. The trunnion tube always remains perpendicular to the longitudinal axis of the trailer/log load.
