<p>PROBLEM TO BE SOLVED: To allow a work vehicle to travel in response to the operation of a travel control lever and the like, and to allow travel control to detect a level difference around a travel body and avoid the level difference.SOLUTION: A high lift work vehicle 1 comprises a crawler travel body 10 that can travel, high lift work devices 30 and 40 provided thereon, a travel control lever 47 and a swiveling angle control dial 48 operable by an operator, and a control unit 50 to control the travel of the crawler travel body 10. Further, it comprises a level difference detector 21 to detect a level difference on a travel road around the crawler travel body. Either a normal travel control mode in which the crawler travel body 10 travels in response to the operation of the travel control lever 47 and the swiveling angle control dial 48, or a level difference detection travel control mode in which, when the existence of a level difference around the crawler travel body 10 is detected by the level difference detector 21, the travel in the direction of the level difference is regulated, is selectable.</p> |
