FIELD: testing engineering. ^ SUBSTANCE: roll bench comprises railway gauge provided with a gap and frame (2) bearing on the base of well (1) through pivots (3) from one side and on air-operated cylinder (4) for pressing it to rolls (8) from the other side. The rolls are arranged in the gap of the railway gauge. The gap in the railway gauge receives two counter-rails secured to the ends of the rails and made of a bar positioned at a level of wheel comb and provided with fining rib and jacks (9) for detaching the wheel pair from the rail heads. ^ EFFECT: expanded functional capabilities. ^ 3 dwg |
