  • Publication number: 20060225940
    Abstract: The present invention provides a construction machine adopting a structure that assures a predetermined sound pressure level along a forward direction relative to the construction machine and allows a warning horn to be miniaturized. Warning horns 12 and 13 are mounted in the vicinity of at least either a left headlamp 9 or a right headlamp 10 provided on the left side and the right side of a vehicle body 3 of the construction machine. The warning horns 12 and 13 are housed inside a bracket 11 used to mount the headlamp 9 or 10. The plurality of warning horns 12 and 13 are disposed on a single side toward the left headlamp 9 or the right headlamp 10. Since a front attachment 7 does not block the sound generated from the warning horns 12 and 13 and thus the warning sound can travel without hindrance along the forward direction, a predetermined sound pressure level is achieved with ease along the forward direction relative to the vehicle body 3.

  • Patent number: 5307631
    Abstract: The displacement of a variable displacement hydraulic pump (1) which is driven by a diesel engine (27) is so controlled as to be set to a first target displacement to keep a pump pressure higher than a load pressure by a predetermined target value, or a second target displacement to limit an input torque on the basis of the pump pressure. Provided is a stand-by flow rate control portion (65) which outputs a third target displacement larger than the minimum value of said first target displacement. The displacement of the pump (1) is controlled so as to be set to the third target displacement when the third target displacement is output from the stand-by flow rate control portion (65).

  • Patent number: 5285642
    Abstract: A load sensing control system for a hydraulic machine sets a variable target differential pressure between a delivery pump pressure and a load pressure of an actuator. A control factor is determined that becomes larger as the deviation between the target differential pressure and the actual differential pressure is increased, and that becomes smaller as the differential pressure deviation is decreased. The control factor also becomes larger as the target differential pressure becomes smaller. The target displacement volume for the hydraulic pump is based on the differential pressure deviation, which is calculated from the target differential pressure and the control factor.

  • Patent number: 5177964
    Abstract: A hydraulic drive traveling system has a pressure compensated low control valve connected between a hydraulic pump and a variable displacement type hydraulic motor for controlling a flow rate of the hydraulic fluid supplied to the motor. The flow rate is controlled in accordance with the delivery pressure of the pump and demanded traveling speed of the motor. When the delivery pressure of the pump is at a high level, the motor is shifted to a first capacity. When the delivery pressure of the pump is low, the motor is shifted to either the second capacity or the first capacity depending upon the demanded traveling speed.
