Each hydraulic excavator 1 is provided with a storage unit (memory 402), a control unit (CPU 401) for executing the work operation and receiving as input a quantitative machine status relating to the work operation, and a communications device 42. The base station 16 is provided with a communications device 16a, a management server 17 for identifying the serial number of the hydraulic excavator 1 and transferring information, and a database 18 for storing various information. The control unit of the hydraulic excavator 1 and the management server 17 of the base station 16 transfer information. With this system configuration, the control unit measures the duration during which the quantitative machine status satisfies a predetermined condition and stores it in the storage unit and transmits the measurement data of the duration to the management server 17 of the base station 16 conditional on the power input key being in the off position, while the management server 17 receives the measurement data of the duration and calculates the cumulative operating time. Further, the quantitative machine status and various event data stored in the storage unit of the hydraulic excavator 1 are sent to the base station 1, while the management server of the base station 16 stores the quantitative machine status and various event data in the database 18 by a predetermined format.

摘要： A hydraulic excavator 1 working in fields includes a controller 2 for measuring a working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12, storing measured data in a memory of the controller 2, and then transferring it to a base station computer 3 via satellite communication, an FD, etc. The transferred data is stored as a database 100 in the base station computer 3. The base station computer 3 reads the data stored in the database 100 for each hydraulic excavator, calculates a working time of a part belonging to each section on the basis of the working time of that section, and compares the calculated working time with a preset target replacement time interval of the relevant part, thereby calculating a remaining time up to next replacement of the relevant part and managing the scheduled replacement timing thereof. Thus, the appropriate scheduled replacement timing of parts can be determined even in a construction machine having a plurality of sections that differ in working time from each other.

摘要： A pilot pressure sensor detects a pilot pressure from an arm operating unit and outputs a pilot pressure signal. A drive signal corresponding to the pilot pressure signal is then outputted from a controller to a solenoid-operated proportional valve. Through the solenoid-operated proportional valve, a pilot pressure is fed to an auxiliary selector valve so that an opening of said auxiliary selector valve becomes greater. Of pressure oil delivered from a first hydraulic pump, a flow rate of the pressure oil to be branched to a side of a by-pass circuit is hence increased. The pressure oil fed through the by-pass circuit passes through a merging directional control valve and is caused to merge with pressure oil fed from a second hydraulic pump. The thus-merged pressure oil is then fed to a hydraulic arm cylinder.

摘要： A hydraulic control system is intended to easily hydraulically back up a trouble caused in an electric system, while employing a control unit (13) to utilize the advantage of electric control, when the displacement of a hydraulic pump (1) is controlled in accordance with a status variable of a hydraulic driving system. To this end, a pump regulator (16) is constructed so as to increase the tilting amount .theta. of a swash plate (1a) with a reduction in pressure of a second hydraulic signal Pc. A characteristic of the pump regulator is set such that a negative control pressure Pco can be employed to operate the pump regulator in place of the second hydraulic signal, and characteristics of a fixed throttle (10) and a spring (18d) in the pump regulator are set such that the pump regulator can be operated in the working range of the negative control pressure. The control unit (13) sets a modified negative control pressure Pc1 as a target value of the second hydraulic signal and determines a second electric signal E corresponding to the target value in a block (102), so that the working range of the second hydraulic signal generated by the solenoid proportional valve (15) is substantially at the same level as the working range of the negative control pressure.

摘要： A controller 24 includes function generators 151, 152. The function generator 151 is set to have such a characteristic that as the detected value P.sub.N of a negative control pressure from a pressure sensor 21 is reduced, a first target tilting amount .theta..sub.N increases from a minimum value to a maximum value, and the function generator 152 is set to have such a characteristic that as the detected value P.sub.B of a control input (pilot pressure) for driving a boom cylinder 6 is increased, a second target tilting amount .theta..sub.B increases from a predetermined minimum value to the same maximum value as the above maximum value. Minimum one of the two target tilting amounts from both the function generators is selected, and a proportional solenoid valve 25 is driven based on the selected minimum tilting amount. This makes it possible to surely suppress an unwanted speed increase of a specific hydraulic actuator other than a boom cylinder, such as a swing motor 9, that would be caused when the tilting amount is controlled based on only the negative control pressure.
