Title:
ROTATING PARKING BRAKE CONTROL DEVICE FOR CONSTRUCTION MACHINERY
Document Type and Number:
WIPO Patent Application WO/2011/142447
Kind Code:
A1
Abstract:
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, drives/controls an upper rotating body by outputting a drive/control signal to a rotating electric motor. The hybrid controller also controls the brake by generating a brake release command signal and outputting a brake release command signal to the brake. A brake release command signal is also generated in a pump controller, and said brake release command signal is transmitted to the hybrid controller via an inter-controller signal line. A brake release command signal is outputted to the brake only when both a brake release command signal is generated in the hybrid controller and a brake release command signal is transmitted from the pump controller via the inter-controller signal line.
