Abstract
A work assist system for a self-propelled hydraulic excavator includes a controller () configured to determine a region in which an assumed excavation amount is obtained from an object to be excavated by one excavation operation of the hydraulic excavator () as a region to be excavated S on the basis of the assumed excavation amount in the one excavation operation of the hydraulic excavator (), and to calculate a work position Pw of the hydraulic excavator () at which the hydraulic excavator () performs a next excavation operation on the basis of the region to be excavated S. A distance Lw from the hydraulic excavator to the work position Pw is calculated by the controller () and this distance Lw is displayed on the monitor ().
