Patent number: 7174968Abstract: The present invention provides a hydraulic excavator provided with a dozer device comprising an arm having a rear end connected to a fulcrum portion provided on a lower frame of a lower traveling body, a dozer blade provided at an extreme end of the arm, and a dozer cylinder for swinging the arm in vertical direction, characterized in that the dozer cylinder and the arm are arranged in a state of forming two sides of a triangle as viewed from the side, the arm swings vertically so that the dozer cylinder does not interfere with a bottom of an upper rotating body rotatably mounted on the lower traveling body, and an approach angle when the dozer blade vertically moved by the arm is placed in the highest position is set to 35 degrees or more, thereby capable of securing travelability equal to an excavator without a dozer device.Type: GrantFiled: May 25, 2004Date of Patent: February 13, 2007Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Takayuki Okunishi, Shinya Nakata, Hiroshi Shimokakiuchi, Hiroshi Morita, Shintaro Sakitani, Yoshiyasu Umezu

Patent number: 6598394Abstract: A control circuit for a construction machine using a control lever for revolving a boom swing in common with a traveling motor and switching pilot pressure via a switching valve has a switch for supplying a switching signal to the switching valve. A pressure switch detects whether the pilot pressure is output from a remote control valve or not. A switching control circuit switches a position of the switching valve to a position for the boom swing cylinder when the switching signal is output from the switch and holds the position of the switch at the position for the boom swing cylinder when the pilot pressure is detected by the pressure switch, to thereby prevent wrong operation in switching.Type: GrantFiled: January 28, 2002Date of Patent: July 29, 2003Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Hiroshi Shimokakiuchi, Hisashi Kadowaki

Patent number: 5101627Abstract: An oil hydraulic circuit for a hydraulic shovel with which a composite operation can be performed readily and smoothly without special skill in operation of the hydraulic shovel. The oil hydraulic circuit comprises a first actuator which can operate with pressure oil from a predetermined one or both of a pair of hydraulic directional control valve sets, a second actuator which operates only with pressure oil from the other hydraulic directional control valve set, a proportional changing over device interposed intermediately in a pipe line communicating the other hydraulic directional control valve set with a first actuator for adjusting the maximum meter-in opening value to the first actuator in response to a magnitude of a signal received at a signal receiving portion of the proportional changing over device, and a controller for arbitrarily adjusting the signal to be supplied to the signal receiving portion of the proportional changing over device.Type: GrantFiled: December 22, 1989Date of Patent: April 7, 1992Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Kazuhiko Fujii, Wataru Kubomoto, Hiroshi Shimokakiuchi, Sumio Kouchi
