Abstract
A system capable of improving accuracy of information relating to the degree of instability of a work machine such as an excavator, the information being provided to an operator of the work machine. Instability degree information, which indicates instability degrees Is, Isof a base body (lower traveling bodyand upper turning body) for which instability values have been assessed as continuous variables, is output to a remote image output device(information output device) such that the form of the output varies continuously depending on continuous changes in the instability degrees Is, Is. An operator of a work machinecan highly accurately recognize the closeness of the current instability degree of the base body to a threshold value at which the base body becomes unstable, and consequently a tolerable range in which the work mechanism, etc. are operated while avoiding instability of the base body.
