FIELD: transport.SUBSTANCE: invention relates to forest industry and can be used in spring floating over rivers with shallow depths. Flat raft section contains aligned row of round timber braced by two flexible ties and vertical binders between logs. The tie is made in the form of flexible thread in the middle of which and at its free ends cargo loops with catches are placed. On the lower branch of thread, vertical binders made of rectangular steel body are placed. By means of lower hole the vertical binder is movably installed on the lower branch of flexible thread, and upper hole of binder body is connected by vertical groove and two side horizontal grooves made at opposite sides of two plates and binder body for bringing upper branch of flexible thread into them ant its fixing. Both branches of flexible thread wrap round timber piece by piece which at the ends of thread are stopped by catch.EFFECT: invention provides simplification of flat raft section formation process, as well as improvement of its transport characteristics during spring floating over rivers with shallow depths.6 dwg |
