    摘要: An apparatus which is capable of substantially prolonging the service live of each component part and preventing the degradation of apparatus specifications before and after parts interchange work by the user. A controller of the image forming apparatus detects a component part requiring interchange from among the component parts based on wear ratios of the respective component parts. The controller determines whether or not to interchange the component part requiring interchange with another component part, based on the wear ratios of the respective component parts and usage rate of the respective component positions. When it is determined that the component part requiring interchange should be interchanged with another component part, the image forming apparatus issues a parts interchange notification.

    摘要: A speed of a hydraulic actuator is matched with that of an electric actuator when the hydraulic actuator and the electric actuator are concurrently actuated. When determination units (71, 72) determine that a boom hydraulic cylinder (31) and a rotation generator motor (11) are concurrently actuated based on a controlled variable of a boom control lever (41) and a controlled variable of a rotation control lever (42), a torque of the rotation generator motor (11) is restricted based on a pump discharge pressure (Pp). Therefore, for example, a torque limit command is generated and output such that a torque limit value (TL2) of the rotation generator motor (11) is decreased with a decrease in discharge pressure (Pp) of a hydraulic pump (3).

    摘要: In stopping a rotary body of an electric rotary excavator (a construction machine), a control-system changing unit of a rotation control device changes a control law from a speed control law to a position control law when a target speed is judged to be smaller than a speed threshold value. By changing to the position control, a larger braking torque can be output to an electric motor as compared with that in the speed control, thereby reliably maintaining the rotary body in a stationary state.

    摘要: In an electric rotary excavator (construction machine) 1, when earth pressure acts on a rotary body 4 in an opposite direction to an instructed direction of a lever, a control-system changing means 150 of a rotation control device 100 increases a torque output of an electric motor 5 that drives the rotary body 4. Accordingly, the torque output can properly react against the acting earth pressure, thereby preventing the rotary body from continuing to be rotated in the opposite direction. Therefore, even when the earth pressure becomes large, the work will not be affected. In addition, when the rotary body is rotated on a slope, the rotary body can be prevented from being rotated back greatly due to the weights of the boom and the arm.
