The invention is based on a turntable-like construction, having the base frame, the tractor linkage drawbar with central reinforcement, the threaded spindle inserted by means of the thread, the pivoting bogey part with the timber-support double-T-rail or U-rail with the two limiting irons, placed by means of two ball races and the adjusting collar onto the threaded spindle. The invention is furthermore based on the clamping device with the double-T-rail with lateral cutouts for the limiting irons, the crescent part with a widened hole in order securely to clamp timber mounted at different heights, and the two clamping chains for clamping the limiting irons. In the case of a high load the provided U-iron part with the two clamping chains is used. The end is formed by a rectangular supporting washer and the hand-spindle clamping wheel. In the case of longer trips, an existing spring is pushed through the hand-spindle wheel and fitted to the crescent part. In the case of the timber-support and clamping rail for the sake of stability points are incorporated on the side facing the timber. In a journey without load a three-point lever is fixed by a shim in a rotationally moveable fashion above the threaded spindle and in a rotationally moveable fashion on the rear-axle frame in a bolt. Tubular part for supporting the drawbar to the single-axle chassis is bolted to the threaded spindle by a fixing bolt, welded-on flat iron, widened hole and the screwed-on cap nut and bolt. By means of a spring catch the drawbar support can be firmly tied to the side.
