To provide a revolving control system for a work vehicle capable of properly restricting revolving operation of a work vehicle while preventing generation of a defect such as disorder of grounding balance.SOLUTION: A revolving control system 7 for a work vehicle comprises: a revolving range setting section 175 which sets a revolving prohibition range 80 that is a revolving range where revolving operation of a backhoe 1 is prohibited and which sets oil pressure cushioning ranges 81 to 82 that are revolving ranges where flow change of pressure oil supplied to a hydraulic motor 51 for revolving is cushioned around the revolving prohibition range 80; and a revolving regulation and control section 176 which restricts the flow rate of the pressure oil supplied to the hydraulic motor 51 for revolving in a range where the revolving operation is not stopped when a revolving position (revolving angle θt) of the backhoe 1 is within the oil pressure cushioning ranges 81 to 82.SELECTED DRAWING: Figure 5

    【課題】接地バランスの崩れ等の不具合の発生を防止しつつ作業車両の旋回動作を適切に規制可能な作業車両用旋回制御システムを提供する。【解決手段】作業車両用旋回制御システム7は、バックホウ1の旋回動作を禁止する旋回範囲である旋回禁止範囲80を設定し、この旋回禁止範囲80の周囲に、旋回用油圧モータ51に供給する圧油の流量変化を緩和する旋回範囲である油圧緩衝範囲81〜82を設定する旋回範囲設定部175と、バックホウ1の旋回位置(旋回角度θt)が油圧緩衝範囲81〜82内であるときに、旋回用油圧モータ51に供給する圧油の流量を、旋回動作を停止しない範囲で制限する旋回規制制御部176とを備える。【選択図】 図5
