The invention discloses a large winch emergency braking redundancy hydraulic control loop. A D single damper brake set hydraulic control loop, an F single damper brake set hydraulic control loop, a Gsingle damper brake set hydraulic control loop, an H single damper brake set hydraulic control loop and a damper brake set redundancy hydraulic control loop are included. According to the large winchemergency braking redundancy hydraulic control loop, damper brake pressure adjusting valves are reasonably allocated to reduce the control containing cavity volume, the single damper brake pressure adjusting valves are used for controlling the single set damper brake pressure, the dynamic response characteristic of the pressure is improved, and the control accuracy and the stability are improved;and solenoid directional valves are adopted for communicating all sets of damper brakes, and the system safety redundancy is improved. The large winch emergency braking redundancy hydraulic control loop has the beneficial effects of being high in pressure control accuracy, good in response characteristic and system stability, capable of achieving safe redundancy and the like.
