  • Hydraulic control device for working machines
    Patent number: 6393838
    Abstract: The composite operation efficiency can be improved in a work machine with a plurality of hydraulic actuators. In the control section the flows to be shared to the respective hydraulic actuators are calculated on the basis of the permissible flow in compliance with an operating quantity of an operating tool, and control commands are outputted to an electromagnetic pressure valve so that the corresponding shared flows are supplied to the respective hydraulic actuators.

  • Construction machine
    Patent number: 6378231
    Abstract: In a construction machine provided with a control unit for outputting actuating commands to actuators based on operating signals from operating levers, interlocking relationships between the operating levers and the actuators can be set as desired respectively, while avoiding enlargement of the memory. Interlocking relationships desired by an operator are adapted to be input into a control unit from a service tool, and the control unit is provided with a memory for rewritably storing the interlocking relationships thus input.

  • Construction machinery
    Patent number: 6293033
    Abstract: In a construction machine including a control unit for receiving operating signals from operating members and outputting operation commands to actuators, by using a monitor and control levers, correlations between the control levers or switches and the actuators, i.e., an input/output relationship between any of the control levers and corresponding one of electro-hydraulic conversion valves, can be freely set. The set input/output relationships are registered in a memory in a rewritable manner.
