The invention discloses a large cold-recycling double-handle logic cooperation control device. The device comprises a left handle, a right handle, a PLC (programmable logic controller) and hydraulic actuators, wherein CAN (controller area network) signals are output to the PLC through control switches on the left handle and the right handle; according to the received CAN signals, the PLC adopts an executive program to output voltage or current signals to the hydraulic actuators under logical relationship control and changes valve core positions of valve coils so as to control the solenoid valves of the hydraulic actuators and control the hydraulic actuators to act ; a voltage value input into the PLC is changed by operating angles of the left handle and the right handle deviating from a neutral position, and accordingly, a walking speed and a steering angle of front and rear wheels are controlled by changing current values output to a walking pump and current values output to steering proportional valves.
