Changzhou Longshengda Machine Co., Ltd.
Longsheng Lifting Machinery Co., Ltd. is located in the beautiful scenery of Taihu Lake - Shanghai-Nanjing high-speed line tin to Yangshan exit, Highway 342 Pan and Lu District Industrial Park, Nanjing tightly linked, along the highway, the traffic is very convenient geographical location and convenient transportation. My company mainly produces fixed load luffing crane, stationary rack luffing slewing cranes, floating cranes, marine cranes, gantry cranes, grab and crane supporting all kinds of parts. Widely used in ports, power, metallurgy, mining industry cargo handling, dredging and construction of the ship heap objects, digging reef, barge, etc. Innovative product design, advanced technology, with multi-purpose, high efficiency characteristics.
Our company produces hot-rolled pulley, made Of high quality steel, is made using a special process. Any production from 260mm-1800mm specifications. Welding are used Ar C02 gas shielded welding, the main technical performance parameters to meet the design requirements. Referring to the Ministry of Communications and strictly original " rolling wheel JT-5028-90" standards, can meet user requirements. With a reasonable structure, high strength, light weight, beautiful appearance, smooth rope groove wear, etc...Sheave grooves general election Q235, Q345, and 35 steel, hot rolled direct water quenching technique to make rope groove surface to obtain a low-carbon martensitic, to raise the rope groove hardness close to the hardness of steel wire rope, wire rope and pulley so forming the friction hardness less, during operation does not lead to localized plastic deformation increased cracking off the rope wear. Greatly improving the wear resistance of the pulley and prolong life, but also improve the service life of the rope. Widely used in a variety of lifting, ports, construction, metallurgy, shipbuilding and other industries. Praised by users.
