摘要： An area limiting excavation control system in an excavation machine having a front device, includes means for setting in advance, an area where the front device is movable. A control unit calculates the position and posture of the front device based on signals from angle sensors. When the front device is inside the set area near the boundary thereof, the control unit calculates a limit value (a) of a bucket tip speed so that a moving speed of the front device in the direction vertical to the boundary of the set area is restricted, and then modifies the limit value (a) depending on a load pressure of an arm cylinder detected by a pressure sensor. It further calculates, from the limit value (a), a limit value of the component of a boom-dependent bucket tip speed vertical to the boundary of the set area, and then modifies a boom operation signal so that the boom-dependent bucket tip speed will not exceed the above limit value. Ground can be excavated to the boundary of the set area without being affected by hardness of the ground to be excavated, while using a simple program.

摘要： A slope excavation control system for a hydraulic excavator and a slope excavation method using a hydraulic excavator include an external reference 80 which extends horizontally in the direction of advance of a target slope face. A vertical distance hry and a horizontal distance hrx from the external reference to a reference point on a target slope face, and an angle of the target slope face are set by using a setting device. When a front reference provided at a bucket end is aligned with the external reference and an external reference setting switch is depressed, a control unit calculates a vertical distance hfy and a horizontal distance hfx from a body center of the excavator to the external reference, then calculates a vertical distance hsy and a horizontal distance hsx from the body center to the reference point of the target slope face by using the distances hsy and hsx as modification values. The control unit then sets the target slope face on the basis of a body of the excavator from the distances hsy and hsx and the angle input by the setting device, thereby carrying out area limiting excavation control.

摘要： Target rotation speed setup section for setting a target engine rotation speed; load detection for detecting a hydraulic pump load; an assist output computation section for calculating an assist output to be generated by a motor generator in accordance with a rotation speed deviation ΔN, which is the difference between an actual and target rotation speed, or in accordance with the hydraulic pump load; an absorption torque upper limit computation section for calculating an absorption torque upper limit value of the hydraulic pump; and an operation signal generation section for generating the operation signal to be output to a pump displacement adjustment device. When the rotation speed deviation ΔN is equal to or more than a setting NC determined in accordance with the assist output value, the absorption torque upper limit computation section reduces the absorption torque upper limit value of the hydraulic pump from the calculated value.
