The invention relates to a steering hydraulic system which comprises a hydraulic oil tank, a hydraulic pump, a driving reversing valve, a steering control device, a steering execution device and a remote reversing valve. The driving reversing valve can enable the oil outlet A or the oil outlet B to output hydraulic oil; the steering control device can enable the working oil port R or the working oil port L to output hydraulic oil; the steering execution device comprises a motor, a steering wheel and a rotating transmission mechanism, a working oil port A of the motor is communicated with a working oil port L of the steering control device, a working oil port B of the motor is communicated with a working oil port R of the steering control device, and the motor drives the steering wheel to steer through the rotating transmission mechanism when rotating. The remote reversing valve enables the oil inlet P to be communicated with or disconnected from the oil outlet B of the remote reversing valve, or enables the oil inlet P to be communicated with or disconnected from the oil outlet A of the remote reversing valve.
