Abstract: A hydraulic excavator includes a cab and a work implement arranged on one lateral side of the cab. The cab includes an operator's seat, front pillars, a roof portion, first and second guide rails, a front window, a monitor device, a monitor, and a support member. The monitor is supported on a first pillar above the monitor device and has a second display screen larger than a first display screen. The support member supports the monitor so as to be movable between an interference position interfering with a movement region where the front window moves between a closed state and an opened state of an opening, and a non-interference position with no interference. Accordingly, a hydraulic excavator can be obtained in which a large-sized monitor can be arranged on a front side of the cab without interference with a movable front window.

Abstract translation: 液压挖掘机包括驾驶室和布置在驾驶室的一个侧面上的作业工具。 驾驶室包括驾驶员座椅，前支柱，车顶部分，第一和第二导轨，前窗，监视器装置，监视器和支撑构件。 显示器支撑在监视器装置上方的第一支柱上，并且具有比第一显示屏大的第二显示屏。 支撑构件支撑监视器，以便能够在干涉位置与前窗在关闭状态和打开状态之间移动的移动区域以及不干涉的非干涉位置之间移动。 因此，可以获得一种液压挖掘机，其中可以在驾驶室的前侧布置大型监视器，而不会妨碍可动前窗。
