Large size, high density, wide range and high concentration are the main characters of dust in the ports and harbor. It easily turns into sludge with water, affecting environment as well as people safety especially in the raining day. Facing with large size and high density dust, road cleaning is becoming a challenge. Jiaoda Shenzhou employs advance fluid mechanics theory, innovative invents vacuum pressure and pure suction road cleaning, reaches cleaning technique revolution, leading new tendency of road sweepers. Vacuum driven road sweeper is fast and efficient, at the same time, it is no water, no dust flying and clean emission. As the pioneer of vacuum driven road sweeper, Jiaoda Shenzhou insists in innovation, and has more than 30 patents, and exports this product to the abroad initially. Further, in the ports and harbor, solving the problem of heavy dust gather together by rolling device, and largely enhance efficient and result of road cleaning.
