Abstract
A remote management system for at least one working machine manages an upper limit of an engine rpm. A hydraulic excavator includes a controller and an instruction switch for selectively instructing three kinds of work modes. The controller includes a target rpm storage unit, a target rpm computer for selecting one of stored upper limits of the target rpm according to an instruction by an instruction switch and computing a target rpm in a range smaller than the selected upper limit, and a communication unit. A server selects a work mode, according to an instruction by an input device, and instructs the selected work mode to the controller. When the work mode is instructed from the server, the target rpm computer computes a target rpm based on the instructed work mode.
