摘要： PROBLEM TO BE SOLVED: To provide a travel controller for working vehicles, which can effectively use the power of a battery, while making an effort to simplify its control, and to reduce its cost, in a working vehicle the wheels of which is driven by an induction motor that is driven by receiving the power supply from the battery by controlling an inverter. SOLUTION: In a vehicle 1 for high lift work which is equipped with this controller for working vehicles, two travel motors (induction motors) 12a and 12b have such characteristics that the starting torque in a low frequency band is small; when a tilt angle detected by a tilt angle detector 62 (tilt angle detecting means) is under a specified angle, an inverter control unit 51 (inverter control means) sets its command frequency to a frequency which is increased according to the increase of a travel command, with its inial value being substantially zero; and when the tilt angle detected by the tilt angle detector 62 is not less than the specified angle, it sets its command frequency to a frequency which is increased, according to the increase of the travel command, with its minimum frequency for generating torque required for prevention of running away of a travel body 10 that is preset, according to the tilt angle as an initial value.

摘要： PROBLEM TO BE SOLVED: To provide an abnormal condition detector capable of properly determining whether an axial force detector detecting a loading working on a freely derricking boom is operated in a normal range or not. SOLUTION: A detection signal from the axial force detector 24 installed to a derricking cylinder 52 derricking the boom is inputted into a control unit 30. When a start-up inspection switch 11 is operated, the control unit 30 operates a derricking control valve 41 and a relief pressure selector valve 42 while housing the boom on a vehicle body for applying a first oil pressure to the derricking cylinder 52. In this time, it is determined whether an axial force detection value detected by the axial force detector 25 is within a proper range or not. Subsequently, in the similar way, a second oil pressure is applied, and it is determined whether the axial force detection value is within the proper range or not. If these values are not within the proper range, a warning is give by an alarm 80.
