To provide a reach type forklift that inhibits vibrations of a machine base at the time of acceleration or deceleration and thereby can reduce operations by an operator.SOLUTION: A reach type forklift comprises a machine base, a pair of right and left front wheels provided on the front side of the machine base, and rear wheels provided on the back side of the machine base to be dislocated from each other in a right to left direction with respect to a linear line passing the center of gravity of the machine base in a travelling direction, and configured to be driven by a driving motor 41. The forklift includes a controller 54 configured to correct the left front wheel to a steering angle based on the acceleration speed or the deceleration speed such that moment applied based on acceleration information or deceleration information of the machine base to the center of gravity of the machine base during the acceleration or the deceleration is cancelled.SELECTED DRAWING: Figure 4
【課題】加速又は減速時に機台のふらつきを抑えてオペレータの操舵を軽減することができるリーチ式フォークリフトを提供する。【解決手段】機台と、機台の前側に設けられた左右一対の前輪と、機台の後ろ側に、進行方向における機台重心を通る直線に対し左右方向にずれた位置に設けられ、走行モータ41により駆動される後輪を備える。機台の加速情報又は減速情報から加速時又は減速時に機台重心を中心にして加わるモーメントを打ち消すように左前輪を加速度又は減速度に応じた操舵角に補正するコントローラ54を備える。【選択図】図4
