SMOOTHING BAR OF ROAD PAVEMENT FINISHING MACHINE

摘要

FIELD: road-building machinery. SUBSTANCE: smoothing bar is adapted for changing working width of road pavement finishing machine and it is made up of main bar and two movable bars located on its opposite ends for possible displacement. For more accurate displacement and more stable setting of movable bars, main bar is provided with intermediate slides located between main bar and movable bar. These intermediate slides however do not allow for movable bars to be fully extended from main bar. Intermediate slides are provided with guide rods which protrude relative to outer end plates of intermediate slides. Due to that, movable bars can be extended through their full length from zone of main bar. Movable bars which are normally of length equal to half of main bar length allow for smoothing bar to double its length with fully extended movable bars. EFFECT: high efficiency. 11 cl, 5 dwg
