To provide a vibration suppression system for a cargo handling vehicle and a cargo handling vehicle, which are able to effectively reduce, suppress, and offset vibration acting on a cargo with high response compared to conventional ones.SOLUTION: A vibration prevention system for a cargo handling vehicle includes: a sensor 21 that detects a parameter indicating an acceleration along a vertical direction of a cargo handling device 6 of the cargo handling vehicle or a vehicle body; a damping force generation device 23 that applies a damping force for suppressing vibration of the cargo handling vehicle; and a controller 22 that, based on a detected value of the sensor 21, generates a feedback command to be given to the damping force generation device 23.SELECTED DRAWING: Figure 2 【課題】従来よりも高応答で効果的に、荷に作用する振動を低減、抑制、相殺することを可能にする荷役車両の振動抑制システム及び荷役車両を提供する。【解決手段】荷役車両の荷役作業装置６又は車両本体の鉛直方向に沿った加速度を示すパラメータを検出するためのセンサ２１と、荷役車両の振動を抑制するための制振力を作用させるための制振力生成装置２３と、センサ２１の検出値に基づいて、制振力生成装置２３に与えるフィードバック指令を生成するためのコントローラ２２と、を備える。【選択図】図２
