摘要： Provided is a braking control apparatus for a slewing type working machine with a flow control valve actuator (44) increasing an opening of a flow control valve (34) between a slewing hydraulic motor (32) and a hydraulic pump (30) according to an operation amount of a slewing operation member (42); pressure control valves (50A,50B) limiting respective maximums of an inlet and outlet pressures of the hydraulic motor to a set value corresponding to a pressure command signal to be input; a motor-side pressure controller (60) which retains a set pressure of the motor inlet sided pressure control valve to a pressure for motor driving and lets a set pressure of the motor outlet side pressure control valve be a set pressure for a braking torque corresponding to an operation amount of a braking operation member (58) other than the slewing operation member; and a valve opening limiter (48A,48B) reducing the opening of the flow control valve in correspondence with the operation of the braking operation member.

摘要： The present invention relates to a device for damping undesirable oscillations of a crane member (1) which is pivotally movable by means of at least one hydraulic motor (5, 5'). The hydraulic circuit (8) has a restriction (13) co-operating with a circuit-closing device (14; 18) the purpose of the restriction being to convert energy inherent in the system to heat in the hydraulic oil. The device includes means (14, 15, 16, 16') for controlling the closing device (14; 18) according to instantaneous conditions and/or changes or conditions, such as pressure and/or flow, in the hydraulic circuit (8). The energy-converting action of the restriction (13) is instantaneously activated as soon as a certain condition and/or a certain change of condition occurs. The conduit (12) in which the restriction (13) lies is completely shut off, rendering flow of oil through the restriction impossible, as long as the energy-converting action of the restriction is not called for.

摘要： The invention relates to a method for regulating especially the pivoting device of a mobile machine, especially a construction machine such as a hydraulic excavator or similar. A hydraulic pump (3) functioning in a closed circuit (5), especially a pivot circuit (5), is driven by at least one driving motor (1), especially a diesel motor (1). Said hydraulic pump (3) feeds at least one hydraulic motor (4) whose energy is transmitted to a mass (7) to be sped up or slowed down, especially a live ring of a revolving superstructure interacting with the working devices, by means of a downstream, especially mechanical gear (6). A set value-actual value comparison of the nominal and limit number of revolutions of the driving motor (1) is carried out especially when the mass (7) is being slowed down and in the event that a predetermined number of revolutions is exceeded, especially the limit number of revolutions of the driving motor (1), the braking pressure in the closed circuit (5), especially the pivot circuit (5), is reduced.

摘要： Unit cranes consist of three hinged arms (13-15), the middle arm (14) being in the form of a polygon comprising a number of units jointed together, the flexibility of the units being arranged by influencing the units internally. The object of the invention is to achieve improved traction curves and speed curves, and this is effected by influencing the movement of the units from the outside by means of a hydraulic mechanism (38).

摘要： In drive control of an operating machine configured to drive a structure by a hydraulic motor (2) configured to be driven by operating oil supplied from a hydraulic pump (10) and an electric motor (3) configured to cooperate with the hydraulic motor (2), a speed command generated based on a manipulation amount of a remote control valve (5) 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 (2) and pressure difference feedback control performed based on an operating oil pressure difference between a suction port and discharge port of the hydraulic motor (2). 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 2, is ejected, and the tilting angle of the hydraulic pump (10) is controlled. Thus, the amount of oil supplied from the hydraulic pump to the hydraulic motor is controlled in accordance with the manipulation amount of the remote control valve, the rotation speed of the hydraulic motor, and the operating oil pressure difference between the suction port and discharge port of the hydraulic motor. As a result, energy loss is suppressed.

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.
