摘要： Provided is a communication system for working machines, which makes it possible to transmit desired messages from sites, where the working machines are arranged, to their corresponding work administration centers at timings as needed. When a mail switch 10 arranged on a working machine 7 is operated to send information to a server 1, a terminal user-company identification unit 14 identifies, on the basis of a terminal information database 18, a user to which the information so received is to be sent. A user-company-dependent mail selection unit 15 selects customer information 19a on the user from a customer database 19. At a transmission mail creation unit 16, a corresponding new message 16a is created. The mail is then transmitted from a mail output unit 17. In this manner, a desired message can be sent from each working machine 7 at a remote location to the corresponding user at a timing as needed.

摘要： A method and system for managing a construction machine and processing apparatus therefor includes a controller 2 mounted on a hydraulic excavator 1 working in fields. An operating time for each of an engine 32, a front 15, a swing body 13 and a travel body 12 is measured and stored in a memory of the controller 2. The measured data is transferred to a base station computer 3 and stored in a database 100 inside the base station computer 3. The base station computer 3 reads, per hydraulic excavator, the data stored in the database 100 and then prepares and outputs a distribution graph of the number of operated machines with respect to the working time (engine running time) of the hydraulic excavator. While looking at the distribution graph, a machine maker estimates the number of hydraulic excavators to be renewed and estimates the sales quantity of hydraulic excavators, thereby setting up a production plan of hydraulic excavators.

摘要： The hydraulic circuit system for civil engineering and construction machines includes a first pressure adjusting device (130) arranged between first variable restrictors (107, 107a) of a left traveling directional control valve (47) and a first traveling motor (57) for controlling the pressure downstream of the first variable restrictors to a value corresponding to a first signal pressure and a second pressure adjusting device (133) arranged between second variable restrictors (108, 108a) of a right traveling directional control valve (49) and a second traveling motor (58) for controlling the pressure downstream of the second variable restrictors to a value corresponding to a second signal pressure. A shuttle valve (136) detects a higher one of load pressures of the first and second traveling motors as a maximum load pressure. When performing the combined operation in which the first and second traveling motors are driven with at least one of a plurality of working actuators (53-56) simultaneously, signal selection valves (131, 135, 170) are actuated so as to supply the maximum load pressure to the first and second pressure adjusting devices as the first and second signal pressures. Consequently, in a combined operation of traveling and performing other works, a communication circuit (110) is activated along with the operation of a working actuator whereby even if a hydraulic fluid supply circuit (104) of the second traveling directional control valve communicates with a hydraulic fluid supply circuit (103) of a first traveling directional control valve, the differential pressures across the first and second variable restrictors become almost the same, thereby achieving a stable straight traveling.

摘要： A hydraulic actuator is driven by hydraulic fluid discharged from a hydraulic pump, for controlling driving of the actuator. A valve has a meter-in circuit for introducing the hydraulic fluid discharged from the hydraulic pump into the actuator. The valve also has a meter-out circuit for returning fluid from the actuator, into a tank. The meter-out circuit is provided with a main valve for controlling the return fluid from the actuator, and a pilot circuit including a variable restrictor. When the main valve is closed, the pilot circuit is closed, and when the main valve is open, its degree of opening varies depending upon an amount of restriction of the variable restrictor. A controller varies the amount of restriction of the variable restrictor valve in accordance with the driving pressure of the actuator.

摘要： A hydraulic driving apparatus has at least one hydraulic pump, a plurality of hydraulic actuators driven by hydraulic fluid discharged from the hydraulic pump, a tank to which return fluid from the plurality of hydraulic actuators is discharged, and a flow control valve associated with each of the plurality of hydraulic actuators. The flow control valve has a first main variable restrictor for controlling flow rate of the hydraulic fluid supplied from the hydraulic pump to the hydraulic actuator, and a second main variable restrictor for controlling flow rate of the return fluid discharged from the hydraulic actuator to the tank. A pump control operative in response to the difference between the discharge pressure of the hydraulic pump and the maximum load pressure of the hydraulic actuators normally controls the discharge rate of the hydraulic pump so that the pump discharge pressure is raised more than the maximum load pressure by a predetermined value. A first pressure-compensating control operates with a valve determined by the difference between the pump discharge pressure and the maximum load pressure, the value acting as a compensating differential-pressure target value, and pressure-compensation-controls the first main variable restrictor of the flow control valve. A second pressure-compensating control is operative with a value determined by the pressure difference across the first main variable restrictor, the valve acting as a compensating differential-pressure target value, for controlling the second main variable restrictor of the flow control valve.
