DEVICE TO LAY RAIL LENGTHS

摘要

FIELD: construction.SUBSTANCE: device to lay rail lengths comprises a cross beam with grips arranged at its ends for rails and jacks. Jacks are in pairs installed at the sides of the cross beam in close proximity from the grips for rails and are made as capable of deepening into a ballast prism. In each pair the jacks are connected to each other by stems. Stems are arranged in guides of the cross beam with the possibility of displacement along them. One of the jacks of each pair is connected with a drive of transverse displacement arranged on the cross beam.EFFECT: invention makes it possible to bend a rail length in a horizontal plane with minimum friction against a ballast prism with curve that is close to curve of circumference and to reduce scope of levelling works.9 dwg
