WORK MACHINE OPERATION DEVICE
PROBLEM TO BE SOLVED: To provide a front operation lever device of a work machine, which can improve an interlock operability of different operations while matching an operation direction of an operator and a driving direction of a work device.SOLUTION: A switch 33 is rotatably installed on a tip of a grip part 36, which covers at least a tip of a shaft 35 of a lever 32 that operates vertical motion of a work arm by fluctuating the lever along vertical direction. A rotary axis of the switch 33 is set along a direction oblique to the grip part 36. An interlock operability of different operations can be improved while matching an operation direction of the fluctuation in vertical direction of the lever 32 and the rotation of the switch 33 by an operator OP and a driving direction of the work device.SELECTED DRAWING: Figure 1
【課題】オペレータの操作方向と作業装置の駆動方向とを合致させつつ、異なる動作の連動操作性を向上できる作業機械のフロント操作レバー装置を提供する。【解決手段】上下方向に沿って揺動させることにより作業腕の上下動を操作するレバー32のシャフト35の少なくとも先端部を覆うグリップ部36の先端部にスイッチ33を回動可能に設ける。スイッチ33の回動軸を、グリップ部36に対して傾斜する方向に沿わせる。オペレータOPによるレバー32の上下方向への揺動およびスイッチ33の回動の操作方向と作業装置の駆動方向とを合致させつつ、異なる動作の連動操作性を向上できる。【選択図】図１
