Abstract
A working vehicle configured to raise and lower one of a jib and a boom by using a wire rope wound around a winch, the working vehicle includes: a detection part provided on one of the jib and the boom and configured to detect an angle of one of the jib and the boom controlled to be raised and lowered to determine whether or not an overload detection condition occurs or to perform overload prevention control; an acquisition part configured to acquire the angle of one of the jib and the boom controlled to be raised and lowered, based on a feed length of the wire rope; and a determination part configured to determine that a failure occurs when a difference between the angle detected by the detection part and the angle acquired by the acquisition part exceeds a predetermined tolerance.
