れ油圧シリンダを介装するとともにこれら油圧シリンダ
のピストンロツド側油室を切換バルブを介して選択的に
油圧源に接続し懸架ばねをロックし得るようにした懸架
ばねロツク装置において、前記クレーンブームの旋回中
心が偏番した側の車輪の油圧シリンダの受圧面積を他方

徴とする懸架ばねロツク装置。Hydraulic cylinders are interposed between the vehicle frame and the pair of left and right front wheels and rear wheels, with the center of rotation of the crane boom biased toward one of the front and rear axles, and a switching valve is installed in the oil chamber on the piston rod side of these hydraulic cylinders. In a suspension spring locking device that can selectively connect to a hydraulic power source through a hydraulic pressure source to lock a suspension spring, the pressure receiving area of the hydraulic cylinder of the wheel on the side on which the rotation center of the crane boom is offset is connected to the hydraulic pressure on the other side. A suspension spring lock device characterized by having a pressure receiving area larger than that of a cylinder.
