More Information
Summary:To provide a work machine capable of accurately calculating the orientation of a work machine body and a front work device.SOLUTION: Disclosed is a hydraulic excavator 100 which includes: an upper revolving superstructure 2; and a receiver 60 for measuring the orientation of a front work device 1 based on navigation signals received by each of two GNSS antennas 40a, 40b. Two GNSS antennas are respectively located in the upward of at least one of a first region behind the front work device on the upper surface of the upper revolving superstructure and a second region on the upper surface of the front work device, and arranged at an interval in the front-rear direction of the front work device.SELECTED DRAWING: Figure 1 【課題】作業機械本体やフロント作業装置の向きを精度良く演算できる作業機械を提供すること。【解決手段】２つのＧＮＳＳアンテナ４０ａ，４０ｂがそれぞれ受信した航法信号に基づいて上部旋回体２及びフロント作業装置１の方位を計測する受信機６０とを備える油圧ショベル１００において，２つのＧＮＳＳアンテナは，それぞれ上部旋回体の上面におけるフロント作業装置の後方の第１領域とフロント作業装置の上面の第２領域の少なくとも一方の領域の上方に位置し，フロント作業装置の前後方向に間隔を介して配置されている。【選択図】 図１
