DEVICE FOR CONTROLLING WORKING UNIT OF CONSTRUCTION EQUIPMENT
Provided is a device for controlling a working unit of construction equipment which comprises a hydraulic control device configured to hydraulically control a working unit and operated by an operating lever, a plurality of sub-electronic control units (ECU) electrically connected with the hydraulic control device, a main ECU configured to receive information on states of the hydraulic control device and the plurality of sub-ECUs, a relay configured to apply or cut off electric power to the plurality of sub-ECUs by a signal generated from the main ECU, and an emergency mode switch configured to turn an emergency mode on/off, wherein, when the emergency mode switch is turned on, the relay to which electric power is cut off according to a main ECU's failure diagnosis signal applies or cuts off electric power to the plurality of sub-ECUs by movement of the operating lever.
