摘要： The control method (100) controls a movable member of an excavator including a movable member holding a load, an actuator with electric motor and static brake, a control unit and a motion sensor unit. Static brake and electric motor generate respectively an upper threshold brake force and an upper threshold motor force. The control method (100) includes: an immobilization step (102): static brake generates said upper threshold brake force and said electric motor is stopped, a slippage detection step (104): said control unit detects whether electric actuator is moving despite said static brake, in case said electric actuator is moving, a motor energizing step (106): electric motor generates a motor force equal or superior to upper threshold brake force in a direction opposite to the slippage direction, and after said motor energizing step (106), a brake release step (108): said control unit releases said static brake.

摘要： Provided is a swivel joint for which replacement costs can be kept low when worn. A swivel joint (A) for supplying and discharging various types of fluid between the top and bottom of a rotating platform comprises an outer cylinder (1), an intermediate cylinder (2), and an inner cylinder (3) that are fit concentrically around a central axis. The intermediate cylinder (2) can freely rotate with respect to the outer cylinder (1) and the inner cylinder (3), and a hydraulic fluid flow channel (4) is provided between the outer cylinder (1) and the intermediate cylinder (2). A hot water flow channel (5) between the lower portion of the inner cylinder (3) and the intermediate cylinder (2) comprises inner annular grooves (G) formed on the inner circumferential face of the intermediate cylinder (2). An air flow channel (6) between the upper portion of the inner cylinder (3) and the intermediate cylinder (2) comprises outer annular grooves formed on the outer surface of the inner cylinder (3). It is possible to suppress replacement costs because replacing the inner cylinder, which is the smallest part, suffices if the sliding surface opposite of the inner annular grooves (G) of the hot water flow channel (5) becomes worn.

摘要： An excavator includes an electric load, an electrical energy storage unit including an electrical energy storage part (19) that supplies electric power to the electric load, and a control unit (30) that controls an amount of charge to the electrical energy storage part (19) so that a charge rate of the electrical energy storage part (19) is between a system control upper limit value and a system control lower limit value. The control unit (30) controls the amount of charge to the electrical energy storage part (19) based on a changing trend of a detection value of the charge rate.
