ABSTRACT:
An excavation area setting system for area limiting excavation control in construction machines, with the excavation control being performed to calculate a target speed vector for control of a front device on the basis of a body, modify the target speed vector to limit a moving speed of the front device in the direction toward a boundary of a preset excavation area when the front device comes close to the boundary of the excavation area, and move the front device along the boundary of the excavation area. To set the excavation area, an external reference is installed horizontally outside the hydraulic excavator and a depth from the external reference to the boundary of the excavation area is set by using a setting device. The excavation area is set in a manner matched with the excavation control in which calculation is executed based on the position of the body.
