The invention provides a steering system of an engineering vehicle and a loader-digger. The steering system comprises a direction control device which comprises a steering wheel, a steering oil cylinder and a steering wheel, and the steering oil cylinder is in transmission connection with the steering wheel and the steering wheel; a displacement sensor which is configured to detect piston displacement of the steering oil cylinder; an aligning motor which is in transmission connection with the steering wheel to drive the steering wheel to be aligned; and a controller which is in signal connection with the displacement sensor and the aligning motor and is configured to send out a control signal according to the piston displacement detected by the displacement sensor so as to control the aligning motor to drive the steering wheel to be aligned. The loader-digger comprises the steering system. The control portability of the steering system can be improved.
