CONSTRUCTION MACHINE AND CONSTRUCTION MACHINE MANAGEMENT SYSTEM
The present invention acquires soil quality information of the ground while excavation work is performed at a work site. A hydraulic excavator (1) includes a work attachment (20), a drive unit (71), a load cell (61), a machine load calculator (503), a soil pressure load calculator (504), and a soil quality estimator (505). The machine load calculator (503) calculates, from orientation information of the work attachment (20) and information about a load that the drive unit (71) receives, a machine load, which is a load that a bucket (23) receives from earth and sand. The soil pressure load calculator (504) calculates, from a shape of a soil mass, the orientation information, the shape of the bucket (23), the density of the soil, a wall surface frictional angle, a soil pressure load.
