AUTOMATIC CONTROL SYSTEM FOR EXPANSION AND CONTRACTION OF SCREED OF ASPHALT FINISHER AND ASPHALT FINISHER
To provide an asphalt finisher capable of reducing the workload of preliminary preparation and performing high-precision paving work by labor-saving and manpower-saving.SOLUTION: In an automatic control system for expansion and contraction of screed of asphalt finisher and asphalt finisher, a laying boundary part BS being a boundary between a form material 3 and a surface to be paved 2 continuous in the laying direction by an asphalt finisher 1 is detected by a sensor unit 5, and when a widener outer end part 132 of a left widener 13L of a screed 12 deviates from a proper state existing on the laying boundary part BS and deviates to the right and left, a screed control device 6 controls expansion and contraction of a hydraulic cylinder 131 to automatically return it to a proper state.SELECTED DRAWING: Figure 2
【課題】事前準備の作業負担を減らすと共に、高精度な舗装作業を省力化・省人化して行えるアスファルトフィニッシャを提供する。【解決手段】アスファルトフィニッシャ１による敷設方向に連続する型枠材３と被舗装面２の境界である敷設境界部ＢＳをセンサ部５にて検知し、スクリード１２の左ワイドナ１３Ｌのワイドナ外端部１３２が敷設境界部ＢＳ上にある適正状態からずれて左右に片寄ったら、スクリード制御装置６が油圧シリンダ１３１の伸縮を制御して、自動的に適正状態に戻す。【選択図】図２
