摘要： To provide a hybrid type construction machine in which work can be kept on even if the amount of electricity stored in an electric storage device is out of an appropriate value.
Both a hydraulic motor 27 and an electric motor 25 are provided for driving an upper swing structure 20. When the amount of electricity stored in a capacitor 24 is appropriate, the upper swing structure 20 is driven by both the hydraulic motor 27 and the electric motor 25. When the amount of electricity stored in the capacitor 24 exceeds an appropriate value, the mode is changed over to a mode in which the upper swing structure 20 is driven only by the hydraulic motor 27, and an assist electric generation motor 23 is assist-driven or engine-driven to thereby rapidly return the amount of electricity stored in the capacitor 24 to an appropriate range.
The capacity of the capacitor 24 can be reduced, and the amount of electricity stored in the capacitor can be managed without losing the operability of swing motion.

摘要： In a work machine including a solenoid valve that generates a pilot pressure to drive a directional control valve with use of the delivery pressure of a pilot pump as a source pressure, a shut-off valve that shuts off a hydraulic operating fluid from the pilot pump to the solenoid valve, a first sensor that senses the amount of operation of an operation lever, and a second sensor that senses a state amount relating to operation of the solenoid valve, whether or not an abnormality of the second sensor exists is determined on the basis of a sensing signal of the second sensor. When it is determined that the second sensor is abnormal, on the basis of a sensing signal of the first sensor, an opening command is made to the shut-off valve if operation of the operation lever is sensed, and a closing command is made to the shut-off valve if the neutral state of the operation lever is sensed.

摘要： A management server (32) is provided in a position away from a hydraulic excavator (1). An operator ID and a vehicle body ID and output characteristic information are stored in a memory device (32A) in the management server (32) in such a manner as to be associated with operability desired by each of operators. The management server (32) extracts the output characteristic information in conformity with the operability desired by an operator from the operator ID and the vehicle body ID, and outputs the extracted output characteristic information to the hydraulic excavator (1). A control device (17) in the hydraulic excavator (1) changes the output characteristics of hydraulic actuators (4D), (4E), (4F), (2B), (3B) based upon the output characteristic information stored in a memory (19).

摘要： The invention provides a work machine that achieves high accuracy of forming a target construction surface and reduced fuel consumption.
A trajectory corrective Pi pressure calculation section calculates a trajectory corrective pressure, which is a control signal for a boom cylinder 32a, based on the distance from a front work device to a target construction surface such that the motion trajectory of the work device is maintained above the target construction surface. A power corrective Pi pressure calculation section calculates a power corrective pressure, which is a control signal for the boom cylinder 32a, based on the bottom pressure of an arm cylinder 32b when the difference between the target power and actual power of the arm cylinder 32b is larger than a predetermined output power value. The boom cylinder 32a is controlled based on the larger of the power corrective pressure and the trajectory corrective pressure while the arm cylinder 32b is being operated.

摘要： A main controller 28 performs automatic stop control to stop an engine in a case where a preset automatic stop condition is satisfied, and includes a power source control processing section 283 controlling power supplied from a capacitor to an electric or electronic facility 70. The power source control processing section 283 estimates a charge amount by which the capacitor 40 is charged by the alternator 41 while an engine 9 is in operation, estimates an electric discharge amount corresponding to power supplied from the capacitor 40 to the electric or electronic facility 70 while the engine 9 is stopped under the automatic stop control, and stops supply of power from the capacitor 40 to the electric or electronic facility 70 when the electric discharge amount is determined to be larger than the charge amount while the engine 9 is stopped under the automatic stop control. This allows reliable suppression of degradation of the capacitor while the engine is under the automatic stop control.
