To provide a travel operation device for an endless track type high elevation work vehicle equipped with an operation panel that can be operated with one hand and whose operation state is stable even if it is shaken sideways.SOLUTION: There is provided a travel operation device 10 comprising an operation panel 11 provided on a deck 4 of a self-propelled endless track type high elevation work vehicle 1, and a controller 70 that controls the rotation of a left motor 60a that drives the left end track and a right motor 60b that drives the right end track according to the operation of an operation rod 20 provided on the operation panel 11. The operation rod 20 of the operation panel 11 is composed of an operating rod main body 21 that can be tilted only in one axial direction from the neutral position, a left swivel switch 24, a right swivel switch 25, and an enable switch 22 that enables these operations. These switches are provided on the position on the operating rod main body 21 that allows a user to operate the left swivel switch 24 and/or the right swivel switch 25 while pressing the enable switch 22 with a finger holding the operating rod main body 21.SELECTED DRAWING: Figure 4
【課題】片手で操作可能であり,横揺れによっても操作状態が安定した操作盤を備えた無限軌道型高所作業車の走行操作装置を提供する。【解決手段】自走式の無限軌道型高所作業車1のデッキ4上に設けられる操作盤11と,該操作盤11に設けた操作桿20の操作に応じて左側無限軌道を駆動する左側モータ60aと右側無限軌道を駆動する右側モータ60bの回転を制御するコントローラ70を備える走行操作装置10を設ける。この操作盤11の操作桿20を,中立位置から前後一軸方向にのみ傾動可能な操作桿本体21と,左旋回スイッチ24,右旋回スイッチ25,及び,これらの操作を有効と成すイネーブルスイッチ22により構成し,操作桿本体21を把持した手指でイネーブルスイッチ22を押しながら前記左旋回スイッチ24及び/又は右旋回スイッチ25を操作可能な前記操作桿本体21上の位置にこれらのスイッチを設けた。【選択図】図4
