The invention discloses a double-control steering device, which comprises a first transmission mechanism, a hydraulic power-assisted steering gear, a motor, a controller, a signal generating device and a steering wheel installed in a chassis cab. The tail end of the steering wheel is connected with the hydraulic power-assisted steering gear, and the hydraulic power-assisted steering gear drives the wheel to steer; the output end of the motor is connected with one end of the first transmission mechanism, the other end of the first transmission mechanism is connected between the hydraulic power-assisted steering gear and the steering wheel, and the controller is in signal connection with the signal generation device and the motor. The steering wheel is operated to drive the wheel to steer through the hydraulic power-assisted steering gear; the signal generating device sends an instruction to the controller, and the controller drives the hydraulic power-assisted steering gear through themotor to drive the wheel to steer. Double control over vehicle steering can be achieved, the steering portability and the steering aligning capacity of the vehicle are improved, and the operation efficiency in occasions with small sites and multiple operation requirements is improved.
