| description | To provide a work machine which can suppress invalidation of operation of an operation device by erroneous detection while preventing erroneous operation of an operation lever (operation device).SOLUTION: A work machine including a seat (32), a right operation device (41) provided on the right side in a horizontal direction of the seat, and a left operation device (43) provided on the left side in the horizontal direction of the seat, comprises: a mass distribution detection device (60) which is provided on the seat and detects distribution of a mass of a worker; an operation invalidation device (78) which makes at least one operation of the right operation device and the left operation device invalid; and a controller (80). The controller includes: an attitude determination part (83) which determines an attitude of the worker based on displacement of the distribution of the mass of the worker; and an operation invalidation control part (85) which controls the operation invalidation device. The operation invalidation control part operates the operation invalidation device when the attitude determination part determines that the attitude of the worker is in an inappropriate attitude as the attitude inappropriate for the operation of a machine body.SELECTED DRAWING: Figure 5
【課題】操作レバー（操作装置）の誤操作を防止しつつ、操作装置の操作を誤検知によって無効とすることを抑制することができる作業機械を提供する。【解決手段】座席(32)と、座席の左右方向右側に設けられた右操作装置(41)と、座席の左右方向左側に設けられた左操作装置(43)とを備えた作業機械において、座席に設けられ、作業者の質量の分布を検出する質量分布検出装置(60)と、右操作装置及び左操作装置の少なくともいずれかひとつの操作を無効とする操作無効装置(78)と、コントローラ(80)とを有し、コントローラは、作業者の質量の分布の変位に基づいて作業者の姿勢を判定する姿勢判定部(83)と、操作無効装置を制御する操作無効制御部(85)と、を含み、操作無効制御部は、姿勢判定部により作業者の姿勢が機体の操作に適していない姿勢としての不適姿勢であると判定すると、操作無効装置を作動させる。【選択図】図５ |
