Abstract
There are provided: a monitoring apparatus that detects an obstacle located around a hydraulic excavator, and outputs obstacle information; and a controller that calculates an operation limiting command for limiting operation of the hydraulic excavator in accordance with an intrusion prohibited area set on the basis of a result of comparison between a movable range of the hydraulic excavator and a monitoring range of the monitoring apparatus and in accordance with the obstacle information from the monitoring apparatus. Thereby, it is possible to appropriately set an intrusion prohibited area, and reduce detection failures and detection errors.
