(54) Work machine management device


(57) An object of the present invention is to allow communication messages to be displayed together with information necessary for driving on the limited space of the display screen on a monitoring panel of a work machine (31-35), and also to allow the communication messages to be understood by an operator regardless of the native language of the operator. Each work machine is provided with a display unit for displaying information transmitted from a terminal device (11,12,21,22), and information including icons (901-904) is transmitted and received between the terminal device and the plural work machines, whereupon the information transmitted from the work machine side or the information received on the work machine side is displayed on a display unit.
