What does 6×7 wire rope mean?
6×7 (6/1) – Fibre Core Wire Rope When supplied with a WSC the rope is more commonly referred to as 7×7. The rope is very popular in smaller diameters from 0.5mm to 2mm where the cable remains very flexible. 6×7 ropes become quite rigid in the larger diameters and are often considered stiff in diameters 6mm and above.
What does 6X19 wire rope mean?
6 x 19S (Seale) -This is a good rope to withstand abrasion or crushing on the drum but its fatigue resistance is decreased. 6 x 25FW (Filler Wire) – To most wire rope users, 6 x 19 means 6 x 25 filler wire.
What are the different sizes of wire rope?
wire rope
| 6 × 7 | haulage rope, transmission, standing rope, aircraft cable. |
|---|---|
| 7 × 19 | aircraft cable, often used in automotive winches. Diameters of ³⁄₃₂, ⅛, ⁵⁄₃₂, ³⁄₁₆, ½ inch. |
| 8 × 19 | extra flexible. |
| 6 × 6 × 7 | tiller or hand rope, whose wires are themselves made of wires. Not strong, but very flexible. |
What is the grade of wire rope?
The strength of wire rope is broken down into different grades, including: Improved Plow Steel (IPS) Extra Improved Plow Steel (EIPS) is 15% stronger than IPS. Extra Extra Improved Plow Steel (EEIPS) is 10% stronger than EIPS.
What is the difference between wire rope and cable?
The term cable is often used interchangeably with wire rope. However, in general, wire rope refers to diameters larger than 3/8 inch. Sizes smaller than this are designated as cable or cords. Two or more wires concentrically laid around a center wire is called a strand.
What is 7×7 wire?
7×7 construction is a medium flexible wire rope ideal for rigging applications where some flexiblity is needed. It is a strong, medium flexible cable commonly used for lifelines, fencing, and safety railings. There are 7 strands and each strand contains 7 individual wires for medium flexibility.
What is the difference between 6×19 and 6×36 wire rope?
6×19 classification ropes provide an outstanding balance between fatigue and wear resistance. They give excellent service with sheaves and drums of moderate size. 6×36 classification ropes are more flexible but less abrasion resistant than the 6×19 classification. Each strand contains multiple small diameter wires.
What is the difference between 6×36 and 6×37 wire rope?
6×37 is a cross laid construction used for general engineering applications. 6×37 is also available with IWRC (independent wire rope core). In the UK 6×36 is a far more popular construction, whilst on the European mainland, vast quantities of 6×37 are used for a variety of applications.
How strong is a 1/2 wire rope?
6 x 19 IWRC Wire Rope
| 6×19 IWRC (Ropes having 15 through 26 wires per strand) | Dia. (in.) | Breaking Strength (tons) Galvanized IPS |
|---|---|---|
| 7/16″ | 8.0 | |
| 1/2″ | 10.35 | |
| 9/16″ | 13.05 | |
| 5/8″ | 16.1 |
How do I choose a wire rope?
Following are the most common characteristics to be considered when selecting a rope for an application.
- STRENGTH. Wire rope strength is usually measured in tons of 2,000 lbs.
- FATIGUE RESISTANCE.
- CRUSHING RESISTANCE.
- RESISTANCE TO METAL LOSS AND DEFORMATION.
- RESISTANCE TO ROTATION.
WHAT IS 1960 grade wire rope?
EIPS (1960) = Extra improved plow steel and 1960 stands for the tensile strength 1960N/mm2. The figure is telling you the grade of wire rope, lower or higher tensile strength will result in different breaking strength.
What is CCS wire used for?
Copper clad steel wire (CCS) combines the high tensile strength of steel as its core and the conductivity properties of copper as its outer layer. The core material is usually low carbon steel and is typically used as either grounding wire or the inner conductor of coaxial cables.
How many wires are broken across the Crown of a rope?
if four or five wires, side by side, are broken across the crown of any strand, when the number of broken wires per rope lay in the worst section of rope exceeds values shown in column C of Table 8.11.2.1.3(cc)(1); or.
What is the replacement criteria for steel wire rope?
Replacement criteria for steel wire rope are based on the worst conditions of diameter and wire breaks. Crown wires are subject to both wear that reduces the diameter of the rope and the breaks that occur in the wear area. Breaks that are visible and occur outside of the crown wear area with the crown wire intact are called valley breaks.
What grade of steel is used to make co-copper clad wire?
Copper clad steel is made to ASTM B-452 standards with 40% conductivity in two tempers: soft and hard drawn. The steel core alloy can theoretically be any grade suitable for the wire’s end purpose.
