PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of lifting a vehicle height of the traveling vehicle while constantly maintaining the a right and left inclined angle of the traveling vehicle as much as possible, regardless of the amount of a load applied to a right and left rolling actuators when lifting the vehicle height of the traveling vehicle by hand operation.SOLUTION: The rolling actuator 38 on a side that previously advanced to the moving direction is stopped and the drive of the other rolling actuator 38 is continued when an absolute value Δx-ΔHo of a finite difference between a value difference ΔHx of current right and left vehicle height sensors 375 and 375 and a value difference ΔHo of the light and left vehicle sensors 375 and 376 at starting of lifting exceeds a first lifting reference value C1 set in advance.COPYRIGHT: (C)2013,JPO&INPIT【課題】手動操作によって走行機体の車高を昇降させる場合において、左右のローリングアクチュエータにかかる負荷の大小に拘らず、走行機体の左右傾斜角度をできるだけ一定に維持した状態で、走行機体の車高を昇降できるようにする。【解決手段】現時点の左右の車高センサ375,376値の差ΔHxと昇降開始時の左右の車高センサ375,376値の差ΔHoとの間の差分の絶対値|ΔHx-ΔHo|が予め設定された第1昇降基準値C1を上回ると、先に移動方向に進んだ側のローリングアクチュエータ38を停止させ、他方のローリングアクチュエータ38の駆動を継続させる。【選択図】図18
