<p><P>PROBLEM TO BE SOLVED: To provide a vehicle for high-lift work capable of lowering a work platform as required while restricting movement of the work platform into a movement restricted area. <P>SOLUTION: The vehicle for high-lift work includes a vehicle body, a boom 5 constituted to be capable of rotating movement, telescopic movement, and derricking movement, a vertical post 6 to be swung to be always positioned vertically, and a work platform 8 provided on the vertical post 6 to be vertically and slidably moved, and further includes an upper operation device for performing operations for rotating, telescoping, and derricking the boom 5, a limit switch 9 for detecting a vertical slide position of the work platform 8, and a controller for restricting actuation allowing the boom 5 and the work platform 8 to be moved to the inside of a movement restricted region A that is preset for preventing interference between the boom 5 and the work platform 8 and an operation cab 2a. The controller sets a boom limit falling angle at which falling of the boom 5 is permitted while restricting the movement of the boom 5 and the work platform 8 to the inside of movement restricted area A correspondingly to the vertical slide position of the work platform 8 detected by the limit switch 9. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
