TRAVELING OPERATION DEVICE OF ENDLESS TRACK TYPE AERIAL WORK PLATFORM VEHICLE

To provide a traveling operation device capable of performing all traveling operation including operation of an enable switch in addition to traveling operation of an endless track type aerial work platform vehicle such as forward operation, backward operation, revolving operation, and stopping operation with one hand.SOLUTION: An operation lever main body 21 constituting an operation lever 20 operated by an operator during traveling is provided with an enable switch 22 and a changeover switch 24 at positions where the operator can operate them with a finger of the hand holding the operation lever main body 21 such that all of them can be operated with one hand. When a changeover command signal is received by a controller 70 in response to the operation of the changeover switch 24 at a normal traveling control state where an aerial work platform vehicle 1 is moved forward, moved backward, stopped, and revolved in accordance with the tilting in the longitudinal direction and tilting in the lateral direction of the operation lever 20, the controller 70 stops the normal traveling control and shifts to spin turn control such that a left side motor 60a and a right side motor 60b are rotated mutually in the opposite direction and the aerial work platform vehicle 1 is revolved on the spot.SELECTED DRAWING: Figure 4 【課題】無限軌道型高所作業車の前進，後進，旋回，停止等の走行操作の他，イネーブルスイッチの操作を含む全ての走行操作を片手で行える走行操作装置を提供する。【解決手段】走行時にオペレータが操作する操作桿２０を構成する操作桿本体２１に，該操作桿本体２１を把持した同じ手指で操作可能な位置にイネーブルスイッチ２２と切替スイッチ２４を設け，これらを全て片手で操作できるようにする。そして，操作桿２０の前後方向の傾動，及び左右方向の傾動に応じて，高所作業車１を前進，後退，停止，旋回させる通常走行制御の状態から，切替スイッチ２４の操作に伴う切替指令信号をコントローラ７０が受信すると，コントローラ７０は通常走行制御を停止して，左側モータ６０ａと右側モータ６０ｂを相互に逆方向に回転させて高所作業車１をその場で旋回させるスピンターン制御に移行するように構成した。【選択図】図４
