galvanized steel rope - this torsion of the steel wire product.Used in its manufacture thin rods (filament) of varying thickness and quality.All of them wove in a spiral in one strand.Any rope consists of several strands twisted and similar metallic or organic core.The core is in the center of the rope, it fills the void, and prevents falling through the adjacent wire stranding.Impregnated antirust lubricant, it protects the inner layer from corrosion during bending of the cable.Applicable wire may be galvanized or uncoated, have a round or shaped cross-section.Its tensile strength is in the range from 900 to 3500 N / mm2.The number of strands in the rope which are disposed around the core, determined its structure.
Steel ropes differ from each other cross-sectional shape, physical and mechanical properties of wires and have a large number of designs.From grade material, such as a core direction of lay, the number of wires in the strands depend flexibility and rigidity of the rope.The more wires used, the rope is more flexible.
Depending on the operating conditions of steel ropes divided into traction, reinforcing, lifting, cargo, towing, shaft bearing, etc.. The widespread use of these products have gained in many industries and utilities.Steel ropes are load-carrying element of transport, road-building, lifting facilities and machines.The quality of these devices ensures safe use of lifting equipment.
By design features a steel rope (GOST 3241-80 and DIN 3051) distinguish the following types:
- single stranding.This cable consists of a single strand.It has a wire diameter suite into a single layer (or multiple layers) around a single wire.
- Dual stranding.This rope consists of several strands that comprise one or two layers, and are arranged around the core.
- Triple lay.It consists of three strands that Formation interconnected and have no core.
lay strands could be cross, single or combined, left or right direction, swirled or neraskruchivayuschegosya way torsion.Inside the wire strands have a point, line, or point-linear touch.
Steel ropes are characterized by the following formula: N * M + L, where N - number of strands, M - the number of wires in a strand, L - the number of cores in the rope.For example, record 36 * 6 + 1 means that the rope consists of six strands, each of which is 36 wires and one core.
Steel cables should be kept wound tightly in rows on the reels (rolls) or folded into a small bay.From corrosion bay with a rope must be protected canvas cover is placed on a wooden pallet (in sunny weather casing removed).For harmful excessive cable bends.Therefore, containers for his chosen carefully.When stored properly, the product life of the rope is not limited.
