QU70, QU80, QU100, QU120Crane Rail is the main component of railway track. Its role is to guide the wheel of the rolling stock forward, withstand the huge pressure of the wheel, and transferred to the sleeper. QU70, QU80, QU100, QU120Crane Rail is mainly used as transportation railway rail for heavy vehicle, and it can be also used in underground mining and crane industry. QU70, QU80, QU100, QU120Crane Rail is widely used in the railway track system. Together with the cooperation with the railroad switch, QU70, QU80, QU100, QU120Crane Rail can make trains running without turning to the other directions. In general,QU70, QU80, QU100, QU120Crane Rail is consist of two parallel steel tracks and lays steadily on the railway sleepers. With the development of railway industry, the steel is widely used in the industry. Compared with other materials, the steel have a larger tolerance to bear more weight. QU70, QU80, QU100, QU120Crane Rail can disperse the weight of the steel tracks and keep the stability of the railway transportation. The stones under the steel tracks can supply a elasticity to the railroad tracks. During the common life, the steel tracks can lay on the base made of concrete and even can be embedded into concrete. Steel rail also can called railway track, steel railway track, etc. Steel rail is a metal groove or ridge that holds, guides, and reduces friction for a moving device or apparatus. It's paved with strip steel route for driving the train, trolley, etc.The standard steel rail usually composed by two joint bars, rails fixed to the sleepers, rail pad under the sleepers for the road, including roadbed, rail connection parts, etc. QU70, QU80, QU100, QU120Crane Rail can provide a continuous, smooth, and least resistance rolling surface for wheels. In electrified railway or automatic block sections, QU70, QU80, QU100, QU120Crane Rail can also be used as track circuits.QU70, QU80, QU100, QU120Crane Rail can be used as cheap rails for a disposable line, for example, if you need to move equipment in a factory, but the equipment is too heavy to be properly transported by car, you can use QU70, QU80, QU100, QU120Crane Rail to build a temporary line. Shanghai Bosheng Industries Co., Ltd pays great attention to quality control and management. Our QU70, QU80, QU100, QU120Crane Rail is completely controlled by iso9001-2008 quality system, and we have obtained the production license of railway products from The Ministry of Railways of China. We have a full set of testing equipment to ensure that all of our rail products meet customer requirements.
