    摘要： In the arm-crowding or track operation, a calculating portion (700d2 or 700d4) calculates a modification gain (KAC or KTR) depending on an operation pilot pressure and a calculating portion (700g) calculates a decrease modification (DND) based on the KAC or KTR, while a calculating portion (700m or 700p) calculates a modification gain (KACH or KTRH) depending on an operation pilot pressure and calculating portions (700q-700s) calculate an increase modification (DNH) based on the KACH or KTRH. A reference target engine revolution speed NR0 is modified using the DND and DNH. In other operations than the arm-crowding and track operations, NR0 is modified using only the decrease modification (DND) calculated from the modification gain just depending on the operation pilot pressure. In the operation where an engine revolution speed is desired to become higher as an actuator load increases, the engine revolution speed can be controlled in accordance with change of the actuator load as well. In other operations, the engine revolution speed can be controlled just depending on the direction and input amount in and by which corresponding operation instructing apparatus is operated.

    摘要： In a region limiting excavation control system for a construction machine, a region where a front attachment (1A) is movable is set beforehand. A control unit (9) calculates the position and posture of the front attachment based on signals from angle sensors (8a-8c), calculates a target speed vector (Vc) of the front attachment based on signals from control lever units (4a, 4b), and modifies the target speed vector such that the target speed vector is maintained as it is when the front attachment is within the set region but not near the boundary thereof. A vector component (Vcy) of the target speed vector in the direction toward the boundary of the set region is reduced when the front attachment is within the set region near the boundary thereof, and the front attachment is returned to the set region and when the front attachment is outside the set region. As a result, the excavation within a limited region can be implemented efficiently and smoothly.
