Abstract
A hydraulic excavator 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 for wirelessly maneuvering the hydraulic excavator 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 . A display unit for displaying a positional relationship between the hydraulic excavator 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 , and also form the target excavation plane by remotely maneuvering the front working device using a joystick 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 can be easily performed.
