The invention discloses a winch control valve bank and a winch control hydraulic system.The winch control valve bank comprises a control valve bank body, a port A1, a port B1, a port A, a port B, a port T and a port X. The port A1, the port B1, the port A, the port B, the port T and the port X. The control valve bank body comprises a balance valve, a one-way overflow valve, an electromagnetic ball valve, a first one-way valve and a shuttle valve, and the port A of the balance valve is communicated with the port A1 of the control valve bank; a port B of the balance valve communicates with a port P2 of the shuttle valve and a port A of the control valve set. A Y port of the balance valve is respectively communicated with a P1 port of the shuttle valve, a T port of the one-way overflow valve, a B port of the electromagnetic ball valve and a B port of the control valve group; a port P3 of the shuttle valve is communicated with a port X of the control valve group; a port P of the one-way overflow valve is respectively communicated with a port B1 of the control valve group, a port A of the electromagnetic ball valve and a port B of the first one-way valve; a port A of the first one-way valve communicates with a port T of the control valve set. The system has redundancy design of safety braking, and is safer and more reliable.
