摘要： A traveling hydraulic working machine has a target revolution speed of an engine commanded by an input and sensors for detecting an operating situation of a hydraulic actuator and an operating situation of a traveling system. A prime-mover revolution speed control modifies the target revolution speed of the prime mover when the operating situation of the hydraulic actuator and the operating situation of the traveling system come into respective particular states, and controls the revolution speed of the prime mover, With the traveling hydraulic working machine, in the combined operation of traveling and working a hydraulic actuator, work can be performed on the basis of the engine revolution speed intended by an operator. When a working load varies, the engine revolution speed is automatically controlled.

摘要： A modification torque computing unit 83 computes 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 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： Hydraulic excavators 1 working in fields each include a controller 2, and an operating time is measured for each of an engine 32, a front 15, a swing body 13 and a track body 12. The measured data is stored in a memory of the controller 2, transferred to a base station computer 3 through satellite communication, an FD, etc., and stored in a database 100 of the base station computer 3. In the base station computer 3, the data stored in the database 100 is read out for each of the hydraulic excavators to obtain a value of an index (e.g., a travel ratio) regarding the state of use of a particular one of the hydraulic excavators and a distribution of the number of operated hydraulic excavators of the same model as the particular hydraulic excavator with respect to the index. The index value and that distribution are compared with each other to determine whether the particular hydraulic excavator is an optimum model. It is therefore possible to make an evaluation after confirming how a customer employs a machine, and to give an advice about the optimum model depending on the state of use of the machines.

摘要： A reference pump-delivery-rate calculating portion calculates a reference delivery rate of a hydraulic pump by referring to a table stored in a memory based on a control pilot pressure for the hydraulic pump. A target pump-delivery-rate calculating portion divides the reference delivery rate by a ratio of a maximum revolution speed to a target engine revolution speed, thereby calculating a target delivery rate. A target pump tilting calculating portion divides the target delivery rate by an actual engine revolution speed and a constant, thereby calculating a target tilting. A solenoid output current calculating portion calculates a drive current to provide the target tilting and outputs the drive current to a solenoid control valve. The pump delivery rate is thereby controlled with good response following input change of an operation instructing device.
