摘要： The Construction machinery includes at least two actuators, a main pump that generates hydraulic energy for driving the actuators, control valves disposed between the main pump and the actuators, a hydraulic pump motor driven by the generator motor that generates energy to be added to the hydraulic energy, and a controller that reduces hydraulic energy generated by the main pump when the hydraulic pump motor driven by the generator-motor generates energy. The construction machinery further comprises changeover valves that selectively change a location at which the energy from the hydraulic pump motor driven by the generator-motor is to be added according to the actuators. The controller changes a reduction rate of the hydraulic energy generated by the main pump depending on a specific actuator to which the energy is to be added.

摘要： A power regeneration device for an operating machine has a hydraulic cylinder and a return line through which fluid returning to a tank flows when the hydraulic cylinder contracts. The return line branches into a plurality of hydraulic lines through a branching part and includes a regeneration line that which leads returning fluid to the tank via a hydraulic motor to which a generator is connected. A control valve line is connected to the branching part and leads the returning fluid to the tank via a control valve. An electricity storage device stores electric power generated by the generator, and an electric amount detector detects the electric amount of the electricity storage device. A flow rate calculator calculates the flow rate of the returning fluid flowing through the regeneration line and the flow rate of the returning fluid flowing through the control valve line depending on an electric amount signal.

摘要： The present invention relates to an anchor bolt and more specifically pertains to a post-installed anchor that is securely anchored to, for example, an existing concrete floor. The post-installed anchor has a sleeve fit on a bolt body and a fixation member arranged on an edge of the bolt body and screwed to a threaded end of the bolt body. The fixation member has an internal threaded end and an expansion end. The expansion end is divided into four expansion pieces by slits. The expansion pieces are arranged to face a head of the bolt body and are slightly widened toward the head of the bolt body. One end of the sleeve forms a tapered face. After insertion of the post-installed anchor into a pilot hole (installation hole) bored in the concrete floor, as the bolt body rotates, the fixation member screwed to the bolt body moves toward the sleeve. This movement causes the expansion end of the fixation member to ride on the tapered face of the sleeve and to be pressed open and extended outward. The expansion pieces of the expansion end are then buckled and bite into an inner circumferential face of the installation hole, so that the post-installed anchor is securely fixed to the installation hole.
