PROBLEM TO BE SOLVED: To simultaneously realize both of the travelling stability of a vehicle body and the riding quality which are contrary elements to each other, in a fork lift truck. SOLUTION: This axle controller comprises a damper for fixing an axle oscillatable to a vehicle body 1, a pressure sensor 14 for detecting the load data acting on a loading device 2, a reel type potentiometer 16 for detecting the lifting height position data of a fork claw 7, a potentiometer 16 for detecting the inclination angle data of a mast 4, and a mounted controller 20 calculating the height of the center of gravity of the whole vehicle body on the basis of the detected load data and the lifting height position data of the fork claw 7, calculating the horizontal position of the center of gravity of the total vehicle body on the basis of the detected load data and the inclination angle data of the mast 4, and further calculating the allowable height of the center of gravity on the basis of the horizontal position of the center of gravity to fix the axle to the vehicle body 1 through a damper fixed on the vehicle body 1 when the height of the center of gravity of the total vehicle body is higher than the allowable height of the center of gravity.
