Marine Building Elevator 6X19s+FC Steel Wire Rope

Specification

Classification by material

1. Carbon steel wire rope is made of high-quality carbon structural steel wire as raw material.
2. Stainless steel wire rope, made of stainless steel wire

Classification by surface condition

1. Phosphating coated steel wire rope (Chinese patent), [1] phosphating steel wire rope is not only an ideal substitute for smooth steel wire rope, but also fully capable of replacing imported steel wire rope [2-3].
2. Galvanized steel wire rope, including hot-dip galvanizing and electro galvanizing. The protection of galvanized layer to steel wire belongs to anode protection. The thicker the galvanized layer, the stronger the corrosion resistance
3. Plastic coated steel wire rope, coating a certain thickness of plastic on the outer surface of steel wire rope or strand, including polyethylene, polypropylene, polyurethane, etc
4. Smooth steel wire rope, the rope making steel wire obtained after heat treatment and cold drawing of raw materials prepared on the surface

Classification according to twisting method

Single strand rope
Also known as single twist rope, made of steel wire
It is made by twisting around the central wire or hemp core, and can lay one or more layers of steel wire.
Double Twist Rope
It is made of double strand rope around the rope core (steel core or fiber core). It can lay one or more layers of steel wire. It is the most widely used variety of steel wire rope.
Three Twist Rope
It is made of double twisted rope as strand rope around the core of rope, mainly used for thick steel wire rope with diameter more than 60mm, such as marine steel wire rope, etc

The marking method of wire rope laying method is as follows:

A right cross lay SZ: right lay of rope, left lay of strand, the lay direction of strand is opposite to that of wire in strand, which is called cross lay
B left cross lay ZS: left lay of rope, right lay of strand
C right lay in the same direction ZZ: rope right lay, strand right lay
D left lay in the same direction: left lay of rope, left lay of strand
E right mixed twist: right twist of rope, left twist of some strands, right twist of some strands
F left mixed twist: left twist of rope, right twist of some strands, left twist of some strands
