<P>PROBLEM TO BE SOLVED: To efficiently use battery power, simplifying structure and reducing costs, in a vehicle for high lift work wherein wheels are driven by induction motors to be driven by power supplied from a battery based on the control of an inverter. <P>SOLUTION: This vehicle for high lift work comprises a travelling body 10 comprising a front pair of driving wheels in right and left as driving wheels among wheels provided in right and left in a front and a rear parts thereof, a steering cylinder 17 for driving a steering mechanism so as to change the steering angle, two travelling motors 12 for separately driving the driving wheels, an inverter IV for converting the direct current from a battery B to the alternating current and supplying it to the travelling motors 12a and 12b so as to commonly drive revolution of the two travelling motors 12a and 12b, and an inverter control section 51 for controlling drive of the travelling motors 12a and 2b by the inverter IV so that the output torque characteristic relative to the number of revolution of the travelling motors 12a and 12b becomes gradual in the case wherein the steering operation is determined based on a result of detection by a steering angle detecting unit 62 fitted to the driving wheel so as to detect the steering angle. <P>COPYRIGHT: (C)2009,JPO&INPIT |
