摘要： An area-limited digging control device for a hydraulic shovel characterized in that an area where a front device (1A) can move is set in advance, that the position and attitude of the front device (1A) are calculated based on signals from angle detectors (8a-8c), that a target speed vector of the front device is calculated based on a detection signal from an operation lever device and a load pressure detected by pressure detectors (270a-271b), that when the front device stays within the set area adjacent to its boundary, a vector component in a direction of approaching the boundary of the set area is reduced, while when the front device stays out of the set area, the target speed vector is corrected such that the front device returns to the set area, and that the operation signal in accordance with its target speed vector is corrected by a load pressure and outputted to proportional solenoid valves (210a-211b), whereby area-limited digging can efficiently be performed and stable and accurate control can be performed irrespective of variation in the load pressure of a hydraulic actuator.

摘要： An area limiting digging control device for a hydraulic shovel characterized in that an area where a front device (1A) can travel is set in advance, that the position and attitude of the front device are calculated by a control unit (9) based on signals from angle detectors (8a-8c), that a target speed vector (Vc) for the front device is calculated based on signals from operation lever devices (4a, 4b), that the target speed vector so calculated is maintained when the front device is not present in the vicinity of a boundary within the set area, while the target speed vector is corrected so as to reduce a vector component (Vcy) in a direction in which the front device approaches the boundary of the set area when the front device is present in the vicinity of the boundary within the set area, and that the target speed vector is corrected such that the front device can return to within the set area when it is out of the set area, whereby an area-limited digging operation can be carried out in an efficient fashion.
