The utility model utility provides an engineering vehicle cab protection device which is provided with a cab and is characterized in that the engineering vehicle cab protection device comprises a mounting frame arranged at the top of the cab, the mounting frame is provided with a mounting end face inclining towards the side face of the cab, and a rigid protection net is mounted on the mounting end face; the end, relatively away from the side face of the cab, of the mounting frame is fixed to the outer side of the top end of the cab through an elastic supporting device, a spring is arranged between the end, relatively close to the side face of the cab, of the mounting frame and the cab, and the spring can support the mounting frame to be away from the cab. And the rigidity of the elastic supporting device is greater than that of the spring. The device can provide multi-stage buffering bearing for high-altitude falling objects and can guide and collect the falling objects in the fixed direction, and losses and
