Shantui Construction Machinery Co., Ltd., in order to meet the needs of the modern urban environment, and constantly increase the intensity of research and development of new products, the company recently launched a SD22R sanitation bulldozer.
According to reports, the machine uses advanced Cummins NT855C engine, strong power, reliable quality, small amount of pollution, environmental protection increased. The engine terminal is equipped with a damping device, which improves the service life of the transmission components. The machine combines the advantages of the TY220 bulldozer (National Gold Award product), adopts advanced hydraulic transmission and hydraulic control technology, and is maneuverable and flexible, with advanced and reasonable structure. With a large-capacity and high-efficiency working device, the fence-type blade structure can effectively prevent the drift of the suspended material, and the increase of the side plates on both sides is more conducive to the collection of garbage. In addition, the cab is equipped with air conditioning and sealed devices, which can effectively reduce noise and give the driver a comfortable working environment. (Source: China Construction News)
