A hydraulic excavator 1 has an area limiting excavation control function for controlling operation of a front working device so as to form a target work plane. A remote control terminal 102 for wirelessly maneuvering the hydraulic excavator 1 is provided in a management office so that entry of setting information of a target excavation plane and remote maneuvering can be performed from the side of the remote control terminal 102. A display unit 71b for displaying a positional relationship between the hydraulic excavator 1 and the target excavation plane is further provided in the remote control terminal. An operator can remotely set the target excavation plane while looking at a screen of the display unit 71b, and also form the target excavation plane by remotely maneuvering the front working device 7 using a joystick 72 with the aid of a control function of an area limiting excavation controller. As a result, the remote setting of the target excavation plane and the remote maneuvering of the hydraulic excavator 1 can be easily performed.
