摘要： The operation hours of the engine (32), front (15), pivot cab (13), and traveling gear (12) of a hydraulic shovel (1) operated on the market are measured. The data is stored in a memory of the controller (2), transferred to a base station computer (3) through satellite communication or an FD, and stored in a database (100). The base station computer (3) calculates, stores, and accumulates the operation time interval of each component of each portion of each hydraulic shovel on an operation hour base of the portion by using operation data every time the component is replaced for repair, reads the data for each hydraulic shovel, calculates the replacement rates of components the replacement time intervals of which are almost equal to that of each component, and the target replacement time interval of the component from replacement time interval corresponding to the maximum replacement rate. Thus an appropriate target replacement time interval can be determined, and an appropriate replacement scheduled time can be determined even if the component is of a portion having different operation hours.

摘要： Construction machine management, permitting operation of a construction machine only under specified conditions and inhibiting its operation in case it is in a state incongruent with preset working conditions. Working conditions for each construction machine are set up by a working conditions setup means, including a geographically divided working area and a working time zone in which a construction machine is allowed to operate in a specified working area. Setup working conditions are stored in a memory means. At the time of starting a construction machine, the status of the construction machine is checked for by a status checkup means which is adapted to check for current position of the construction machine and current time against the working area and working time zone of the setup working conditions. In case a construction machine is found to be in a state incongruent with both of the working area and the working time zone of the preset working conditions, the management inhibits operation of that construction machine.

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 hydraulic driving apparatus for construction machines, wherein a first flow rate control means has first and second flow rate control valves (11a, 11b), and first interlocking means (54, 55) for interlocking the first and second flow rate control valves with a first direction control means (7). The second flow rate control valve has third and fourth flow rate control valves (12a, 12b), and second interlocking means (56, 57) for interlocking the third and fourth flow rate control valves with a second direction control means (9). A first pressure control means has at least a first pressure control valve (13a) adapted to be operated in a closing direction in accordance with a pressure signal, while a second pressure control means has only a second pressure control valve (15b) adapted to be operated in a closing direction in accordance with a pressure signal. A first hydraulic pump (25a) is connected to a first actuator (19) via the first flow rate control valve (11a), first pressure control valve (13a) and first direction control means (7), while a second hydraulic pump (25b) is connected to the first actuator (19) via the second flow rate control valve (11b) and first direction control means (7). The first hydraulic pump (25a) is connected in parallel with first actuator (19) to a second actuator (21) via the third flow rate control valve (12a) and second direction control means (9) but not via the pressure control valve. The second hydraulic pump (25b) is connected in parallel with the first actuator (19) to the second actuator (21) via the fourth flow rate Control valve (12b), second pressure control valve (15b) and second direction control means (9).

摘要： This invention relates to a hydraulic circuit for working machines, provided with a hydraulic fluid source (1), at least one hydraulic actuator (3 or 13) adapted to be driven by the hydraulic fluid supplied from the hydraulic fluid source, flow rate control valves (4; 4A or 14; 14A) adapted to control a flow of the hydraulic fluid supplied to the actuator, and pressure control means (5; 5A or 15; 15A) for maintaining the pressure differences across the flow rate control valves on predetermined levels. The apparatus according to this invention has a first means (20; 23; 35, 36) for selectively producing one of a pressure equal to a load pressure and an intermediate pressure higher than the load pressure but lower than a supply pressure, on the basis of a load pressure on the actuator (3 or 13) and a supply pressure in the hydraulic fluid source (1), and outputting the resultant pressure as a control pressure; a second means (21; 27; 29; 34, 36) for operating the first means to specify a pressure to be selected as a control pressure, i.e. one of the pressure equal to the load pressure and the intermediate pressure; and a communication means (22) for introducing the control pressure to the pressure control means (5; 5A or 15; 15A). The pressure control means is adapted to maintain the above-mentioned pressure difference on the above-mentioned predetermined level when the control pressure is equal to the load pressure, and set the pressure difference to one lower than the predetermined level when the control pressure is the intermediate pressure.
