Abstract

Disclosed is a display device that includes a display unit provided in a cabin of a construction machine, an operating unit with a switch for operating the display unit, and a monitor controller for controlling the display unit and the operating unit, wherein: upon some kind of abnormality being detected by abnormality detection means for detecting abnormalities in mechanisms equipped in/on the construction machine, a warning logo corresponding to the kind of abnormality is displayed on the display unit, and a warning item for displaying information inclusive of details of the abnormality is added to a menu in a list format that contains items, each for executing a previously assigned specific function. Thus, the device improves in a degree of freedom of its configuration and enhances efficiency of information display

Claims

1. A display device for a construction machine, comprising:

a display unit provided in a cabin of a construction machine;

an operating unit with switches for operating the display unit; and

a monitor controller for controlling the display unit and the operating unit;

wherein;

a menu in a list format that contains items, each for executing a previously assigned specific function, is displayed on the display unit;
