description	PROBLEM TO BE SOLVED: To provide a work machine capable of implementing highly safe machine operation by avoiding a stroke end of an EA cylinder.SOLUTION: A work machine includes: an end attachment provided on the tip of an attachment comprising a boom and an arm; a hydraulic pump connected to an engine, and a boom cylinder, arm cylinder, end attachment cylinder, and end attachment drive actuator that are driven by hydraulic oil discharged by the hydraulic pump; a sensor unit for detecting a cylinder position of the end attachment cylinder; and a control unit for controlling output of the end attachment on the basis of a signal from the sensor unit. The control unit, at the time of the end attachment operating, suppresses the output of the end attachment when the cylinder position reaches the vicinity of an end position of the attachment cylinder.SELECTED DRAWING: Figure 3 【課題】本発明は、ＥＡシリンダのストロークエンドを回避して安全性の高い機械操作を実現できる作業機械を提供する。【解決手段】ブーム及びアームを備えたアタッチメントの先端に設けられたエンドアタッチメントと、エンジンと接続された油圧ポンプと、当該油圧ポンプが吐出する作動油によって駆動されるブームシリンダ、アームシリンダ、エンドアタッチメントシリンダ、及びエンドアタッチメント駆動アクチュエータと、エンドアタッチメントシリンダのシリンダの位置を検出するセンサ部と、センサ部からの信号に基づいて前記エンドアタッチメントの出力を制御する制御部と、を有する作業機械であって、制御部は、エンドアタッチメントの動作時に、アタッチメントシリンダのエンド位置近傍に達すると、エンドアタッチメントの出力を抑制する。【選択図】図３
