Patent number: 9212467Abstract: The disclosed rotating parking brake control device obviates the need for an operator to operate an emergency-stop switch. A hybrid controller, to which a brake is connected, outputs a drive control signal to a rotating electric motor to control drive of an upper rotating body and also controls the brake by generating a brake release command signal and outputting the brake release command signal to the brake. A pump controller also generates a brake release command signal, and the brake release command signal generated by the pump controller is transmitted to the hybrid controller through an inter-controller signal line. The brake release command signal is outputted to the brake only when the brake release command signal is generated by the hybrid controller and the brake release command signal is transmitted from the pump controller through the inter-controller signal line.Type: GrantFiled: May 13, 2011Date of Patent: December 15, 2015Assignee: KOMATSU LTD.Inventors: Hiroaki Take, Jun Morinaga, Shuki Akushichi
