摘要： A modification torque ΔT and a torque converter speed ratio e is computed from input and output revolution speeds of a torque converter 31. A first determination coefficient α corresponding to the speed ratio e, and a second determination coefficient β corresponding to a pump pressure are computed. A selector 87 selects the smaller one of these coefficients as a determination coefficient γ, and the modification torque ΔT is multiplied by γ to provide a modification torque ΔTA. An adder 89 adds the modification torque ΔTA (negative value) to a pump base torque TR to provide a modified pump base torque TRA, whereby a maximum pump absorption torque TRA is controlled so as to become TRA. The maximum pump torque reducing control can then be performed while accurately confirming a work situation during the combined operation of travel and a working actuator.

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 pump controller (40) calculates a pump maximum absorbing horsepower and a pump required horsepower based on an accelerator signal, a pump delivery pressure and an operation signal, determines an engine required horsepower (PN) by selecting minimum one of both horsepower values, and calculates a pump required revolution speed based on the accelerator signal, the operation signal and an engine revolution speed signal to determine an engine required revolution speed (NN). The engine controller (40) determines, from the engine required horsepower (PN), a required-horsepower-referenced target engine revolution speed (NK) at which a fuel consumption rate is minimized, and selects larger one of the engine required revolution speed (NN) and the target engine revolution speed (NK) as an engine target revolution speed (NZ) to control an injected fuel amount and fuel injection timing, thereby controlling an engine torque and an engine output revolution speed. Improved operability and less noise can be achieved, and the fuel consumption rate of an engine can be controlled in an optimum way to reduce the fuel consumption rate.

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.
