Changzhou longsheng of hoisting machinery co., LTD is located in the scenic taihu lake - changzhou snow wenyan town;The whole machine production base in the yangshan town of wuxi city mountain industrial clusters, the geographical position is superior, the amphibious transportation is convenient.I plant specializing in the production of port, wharf crane, port portal crane, hot-rolling pulley, grab crane accessories, accessories series.

I plant the production of hot-rolled pulley, choose high quality steel plate, which is produced by a special process.From the 260 mm - 1800 mm Ф Ф specifications of any production.Welding adopt Ar our fleet gas shielded automatic welding, the main technical performance parameters meet the design requirements.The original and strict adherence to the ministry of communications "rolling pulley JT - 5028-90" standards, fully meet the demand of users.With reasonable structure, high strength, light weight, beautiful appearance, smooth rope groove wear etc.Rope pulley groove generally choose Q235, Q345, and 35 steel material, adopts the technology of the hot rolled directly spray quenching, make rope groove surface to obtain low carbon martensite, increase the sheave hardness to close to the hardness of steel wire rope, wire rope and pulley so formed the friction pair of hardness difference is not big, won't produce plastic deformation in the process of operation leads to increased local cracking off wire rope wear.Greatly improve wear resistance of the pulley, prolong service life, and also improve the service life of wire rope.Widely used in all kinds of lifting, ports, construction, metallurgy, shipbuilding and other industries.Well received by users.

Mechanical grab, grab my factory also production and rope type grab, electric grab, underwater salvage grab, rubbish bucket, it is mainly used for docks, ports, garbage disposal, ship loading and unloading, and clear channel and material storage and transportation industry.I plant indepen
