  • Road machine
    Patent number: 10962110
    Abstract: A road machine includes a travel switch to cause the road machine to start traveling, a hydrostatic transmission including a traveling hydraulic pump and a traveling hydraulic motor, a pump regulator to control the discharge quantity of the traveling hydraulic pump; and a controller to control the pump regulator using a pump command current. The pump regulator increases the discharge quantity of the traveling hydraulic pump as the pump command current increases, and the controller increases the pump command current to a predetermined value smaller than a maximum current value in response to the travel switch being turned ON. Alternatively, the pump regulator increases the discharge quantity of the traveling hydraulic pump as the pump command current decreases, and the controller decreases the pump command current to a predetermined value greater than a minimum current value in response to the travel switch being turned ON.

  • Engine control device for construction machinery
    Patent number: 7353105
    Abstract: There is provided construction machinery for switchably controlling rotational speed between a normal and an energy saving mode. Change in workload is detected by means except for change in pressure of a main circuit. It is more convenient to use the machinery in the energy saving mode, increasing opportunities for use in the energy saving mode to suppress fuel consumption and noise.
