2, the present invention changes little to vehicle cab entirety, can do little variation and directly install, significantly reduce improving cost above existing operator's compartment;
3, the suppressing action the present invention due to tipping bucket overhanging end in vehicle travel process can be close to operator's compartment, avoid protective device ceiling with waving in vehicle travel process, and the overall height do not increased when vehicle travels on highway, especially the traveling comfort of operator's compartment under vehicle running state is not affected;
4, the present invention is being out of shape at first by the hit rear ceiling of junk and resilient guiding device, next is only the plastic material distortion in the middle of two-layer bracing frame, impaired not serious time, protective device can only change a part of parts, namely safety pin, protective device ceiling, plastic material accommodation box and plastic material, thus reduce maintenance cost;
5, because resilient guiding device is fixed by screws on the bracing frame of upper strata, and upper strata bracing frame has many group installation tapped bore battle arrays, therefore the present invention is installed the quantity of resilient guiding device, position and length additional and can be changed with different operating mode, and this modular design makes protective device field of application become wide;
6, the invention is not restricted to only install on the vehicle having tipping bucket overhanging end, it also can install with at different operating mode down conversion buffer distance on any transport trolley operator's compartment.
