摘要: A control system for a construction machine stops an upper swing structure at a desired swing stop angle. A main controller sets a swing stop target angle at which an upper swing structure is to be stopped. A swing stoppability determination section reads an angle signal of the upper swing structure with respect to an undercarriage and an angle of a work implement, and determines whether the swing of the upper swing structure can be stopped at the swing stop target angle. A work implement is controlled in such a manner that an extension action of the work implement in a swing radial direction is prohibited or a contraction action of the work implement in the swing radial direction is executed in response to a signal that indicates whether the swing can be stopped and that is determined by the swing stoppability determination section.

摘要: A rotation control system may be provided for a material handling machine. The rotation control system may include a boom and a work tool attached to the boom. A swing motor may be capable of swinging the boom and the work tool. A work tool motor may be capable of rotating the work tool relative to the boom. An input device may generate a first signal indicative of a desired swinging of the boom and a second signal indicative of a desired rotation of the work tool. A controller may be in communication with the input device, the swing motor, and the work tool motor. The controller may be capable of actuating the work tool motor based only on the second signal during a first mode of operation and may be capable of actuating the work tool motor based on swinging of the boom during a second mode of operation.

摘要: A hydraulic machine includes an undercarriage; a rotating structure rotatably mounted on the undercarriage and configured to rotate with and with respect to the undercarriage; a first controller configured to receive user input and configured; a user interface configured to accept commands from a user and output a command signal to the controller; and a first gyroscope fixed to the rotating structure and electrically connected to the controller and configured to provide a data signal of rotation information of the rotating structure to the controller. An axis of rotation of the gyroscope is parallel to the axis of rotation of the rotating structure. The controller is configured to generate a control signal to control the rotating structure and cause the rotating structure to rotate with respect to the undercarriage based on the command signal from the user interface and the data signal from the first gyroscope.

摘要: A hydraulic circuit for use on a construction machine includes a first valve, a second valve, and at least a third valve. The second and third valve each includes at least one inlet port connected to a first outlet port of the first valve. The first outlet port of each of the second and third valves are configured to reduce a first pressure to a second pressure and/or a third pressure downstream of the second valve and the third valve, respectively. The second valve and the third valve also include at least a second outlet port connected to a reservoir tank. A hydraulic motor is connected to the first outlet port of the second valve, which operates the hydraulic motor in a first direction. The hydraulic motor also is connected to the first outlet port of the third valve, which operates the hydraulic motor in a second direction.

摘要: In drive control of an operating machine configured to drive a structure by a hydraulic motor configured to be driven by operating oil supplied from a hydraulic pump an electric motor configured to cooperate with the hydraulic motor, a speed command generated based on a manipulation amount of a remote control valve configured to determine an operation amount of the structure is subjected to speed feedback control performed based on the actual rotation speed of the hydraulic motor and pressure difference feedback control performed based on an operating oil pressure difference between a suction port and discharge port of the hydraulic motor. With this, a tilting angle command is generated such that the operating oil, the amount of which is necessary at the actual rotation speed of the hydraulic motor, is ejected, and the tilting angle of the hydraulic pump is controlled.
