PROBLEM TO BE SOLVED: To provide a working vehicle in which outside lifting/lowering switches for lifting and lowering a working machine which are operated by a worker while the worker is out of a drivers seat are disposed at the left and right sides of a connection part of the working machine, respectively, so that the outside lifting/lowering switches can be safely operated with ease.SOLUTION: In a working vehicle with a lift arm 9 for lifting and lowering a working machine 11, a working machine lifting/lowering lever 21 for lifting and lowering the lift arm 9 is provided on one of the left and right sides of a drivers seat 6 of the working vehicle. In the left and right vicinity of the lift arm 9 of the traveling machine body, left and right outside lifting/lowering switches SW1-SW4 constituted of push button switches for lifting and lowering the lift arm 9 and of an automatic return type, the switches operated while an operator is out of the drivers seat 6, are disposed, respectively. A controller 25 is provided with lift arm lifting/lowering position control means, and lift arm outside lifting/lowering means for invalidating an operation output of the working machine lifting/lowering lever 21 in the lifting/lowering operation condition of the left and right outside lifting/lowering switches SW1-SW4.COPYRIGHT: (C)2015,JPO&INPIT【課題】作業者が運転席から降りた状態で操作する作業機昇降用の外部昇降スイッチを作業機連結部の左右両側にそれぞれ配設し、この外部昇降スイッチ操作の容易安全化を具現する。【解決手段】作業機11昇降用のリフトアーム9を備えた作業車両において、作業車両の運転席6の左右一側に前記リフトアーム9昇降用の作業機昇降レバー21を設け、走行機体の前記リフトアーム9の左右近傍にはオペレータが運転席6から降りた状態で操作するリフトアーム9昇降用で且つ自動復帰型の押しボタンスイッチで構成されている左右外部昇降スイッチSW1~SW4をそれぞれ配設する。コントローラ25にはリフトアーム昇降ポジション制御手段,左右外部昇降スイッチSW1~SW4の昇降作動状態では作業機昇降レバー21の操作出力を無効にするリフトアーム外部昇降手段を設ける。【選択図】図5
