Abstract:
A hydraulic excavator includes: a hydraulic pump driven by power generated by an engine; a work device that operates by a plurality of hydraulic cylinders driven by power generated by the hydraulic pump; an actuator control section that controls the boom cylinder in such a manner that a tip end of a bucket is located on or above a target surface; a control point position calculation section that calculates a bucket claw tip position on the basis of angle sensors; and a power generator control section that imposes more limitations on output power ranges of the engine and the hydraulic pump when a distance between the claw tip position and the target surface is equal to or smaller than a threshold D than those when the distance between the claw tip position and the target surface is larger than the threshold D.

Claim (Index 1):
A construction machine, including:\n a prime mover; a hydraulic pump driven by power generated by the prime mover; a work device that operates by a plurality of hydraulic actuators driven by power generated by the hydraulic pump, the work device including a work tool on a tip end thereof; and an actuator control section that controls at least one of the plurality of hydraulic actuators in such a manner that a tip end of the work tool is located on or above a target surface that is arbitrarily set, the construction machine comprising: a control point position calculation section that calculates a position of a control point set with respect to the work device on the basis of quantities of state related to a position and a posture of the work device; and a power generator control section that, when a distance between the target surface and the control point calculated on the basis of the position of the control point and a position of the target surface is equal to or smaller than a threshold, executes output power limiting control that is a process for imposing more limitations on an output power range of at least one of the prime mover and the hydraulic pump than those when the distance between the target surface and the control point is larger than the threshold.
