- are the main constructural element of lifting, transport, earthmoving machinery and mechanisms. This product made of wire contains a large number of types, constructions. Steel ropes have the differences in the shape of cross section, wire mechanical characteristics, core types. Steel ropes - are one of the most widespread kinds of metal products; they are used in transport, mining, engineering and agricultural industries.
Metal or organic cores are used for steel ropes production. Metal core is a strand or construction rope 7õ7 and is made of wire èçãîòàâëèâàåòñÿ. organic core is made of polypropylene yarns. Steel rope marking - is the main characteristic which determines the further rope exploitation. Steel ropes marking groups: 1370, 1670, 1770, 1960 N/mm2.
Steel ropes are made with preliminary deformation (non unwiding). This fact provides the following advantages:
ends of dangling wires in the steel rope do not "ringe", there is not steel rope rotating around its axis during pruning and free ends of steel rope do not untwist. Steel ropes are made of wire without coating or galvanized.
Zinc coating protects the rope aggressive environment, increases the corrosion resistance of the rope during exploitation. Useful life of galvanized rope is 3 times higher than of the rope without zinc coating.
Slings made of steel ropes - are the handling removable devices, which are used for lifting and transporting cargo by means of hoisting mechanisms (cranes, lift trucks). Slingssuitable to the mass and character of cargo lifted, depending on the quantity of pathes and angle of their inclination are used for cargo strapping; slings for general purpose are selected in such a way so that the angle between its pathes does not exceed 90°C. Slings are manufactured according to GOST 25573-82 in conformity with the rules of hoisting mechanism design and safe exploitation. Rope slings have the greatest strength in comparison with other slings (for example synthetic), moreover they are one of the most reliable. Rope slings defects are easily detected, that is why they are used for lifting of heavy, massive cargo in the places with high concentration of people and equipment. Rope slings are used for lifting and moving of cargo with the weight up to 16 tons. Slings marking: ÓÑÊ, 1ÑÊ, 2ÑÊ, 3ÑÊ, 4ÑÒ.
