It is mainly composed of a wheel drive motor 2, a pad 3, a gear 4, a screw 5, a crawler 6, and a connecting device. In view of the complex situation of the pipeline structure in the bridge, a crawler is selected instead of a round wheel to directly contact the ground. The advantage of the crawler 6 is not only its better passing capacity and stability, but also its ability to reduce the pressure on the surface of the pipeline, thereby reducing the risk of damage.
