PROBLEM TO BE SOLVED: To detect the back-and-forth moments working on a vehicle through a tilt cylinder precisely and continuously without receiving an adverse effect due to operation of a change-over valve to control supply of working oil to the tilt cylinder. SOLUTION: This load moment measuring device is constituted by furnishing furnishing a pressure sensor 21 to detect pressure on the rod side of a tilt cylinder 7, a pressure sensor 22 to detect pressure on the bottom side of the tilt cylinder 7 and a comuting means to compute thrust F of the tilt cylinder 7 from pressure P1 on the rod side and pressure P2 on the bottom side, and it measures a load moment M in accordance with the thrust F. Additionally, when the tilt cylinder 7 comes to be stroke end, a load moment equivalent value is measured from an inclination, lifting height and a load at the time stroke end instead of the aforementioned pressure.
