摘要： A security system for a construction machine including a construction machine equipped with a body controller for storing a first password, management apparatus arranged in a location apart from the construction machine and a portable communications unit for storing a second password provided communicably with the management apparatus and the body controller. The portable communications unit, receiving the first password from the management apparatus, replaces the second password with the first password. The body controller determines whether the second password output from the portable communications unit coincides with the first password. In case these passwords coincide with each other, an engine drive signal is output. Otherwise the engine is kept inoperable. This prevents possible theft of a construction machine.

摘要： A working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12 of a hydraulic excavator 1 working in fields is measured. Measured data is stored in a memory of a controller 2 and then transferred to a base station computer 3 via satellite communication, an FD, etc. to be stored in a database 100. At each repair/replacement of a part in each hydraulic excavator, the base station computer 3 calculates, based on the operation data, a replacement time interval of the part on the basis of the working time per section to which the part belongs, and then stores and accumulates it. The base station computer also reads the stored data for each hydraulic excavator, determines, for each part, a replacement rate of the part having the substantially equal replacement time interval, and calculates a target replacement time interval of the part in accordance with the replacement time interval corresponding to a maximum replacement rate. Thus, the appropriate target replacement time interval can be decided and the appropriate scheduled replacement timing can be determined even for parts belong to a plurality of sections that differ in working time from each other.

摘要： Pump ports 9p, 10p, 11p, 13p of boom, arm, bucket and first travel directional control valves 9 - 11, 13 are connected to first and second hydraulic pumps 1a, 1b through feeder lines 93a, 93b; 103a, 103b; 113a, 113b; 133a, 133b. Auxiliary valves 91a, 91b; 101a, 101b; 111a, 111b; 131a, 131b controlled respectively by proportional solenoid valves 31a, 31b; 32a, 32b; 33a, 33b; 34a, 34b are disposed in those feeder lines. The auxiliary valves each have a function as a reverse-flow preventing function and a variable resisting function including a flow cutoff function, whereby a joining circuit and a preference circuit can be realized in the closed center circuit with a simple structure and further, a preference degree and metering characteristics can be set independently of each other during the combined operation of plural actuators.

摘要： In a hydraulic controller, in order to easily provide a hydraulic back-up in the event of a failure of an electric system while maintaining a benefit of electrical control using a control unit (13) when controlling a displacement of a hydraulic pump (1) in accordance with a property of a hydraulic driving system, a pump regulator (16) is constructed such that the tilt θ of a swash plate (1a) increases as the pressure of a second oil pressure signal P.c decreases, the pump regulator is characterized in that a negative control pressure can be used instead of the second oil pressure signal, and the properties of a fixed throttle (10) and the pump regulator spring (18d) are set such that the pump regulator can be operated within an operation range of the negative control pressure. In a controlling unit (13), a negative control pressure Pc1 corrected in a block (102) is made to be a target value of the second oil pressure signal, a second electric signal E corresponding to the target value is obtained, and the operational range of a second oil pressure signal generated by a solenoid proportional valve (15) is made substantially equal to the negative control pressure.
