(1) Cable laid and 6 x 19 and 6 x 37 slings shall have a minimum clear length of wire rope 10 times the component rope diameter between splices, sleeves or end fittings.

(c) Safe Operating Temperatures. Fiber core wire rope slings of all grades shall be permanently removed from service if they are exposed to temperatures in excess of 200o F. When nonfiber core wire rope slings of any grade are used at temperatures above 400o F, or below minus 60o F, the sling manufacturer"s recommendations shall be followed.

(3) Where rope clip attachments are used, they shall be made with U-bolts on the dead or short end of the rope and the saddle on the live end. The minimum number of clips for end attachments shall be not less than indicated in manufacturer"s tables, but in no case shall be less than three for any permanent installation. Clips shall be drop-forged steel. The clips shall be spaced at a distance equal to at least six times the diameter of the rope. All clip or clamp bolts shall be kept tight after tightening while rope is under tension.

(a) Factor of Safety. All rope to be used for regular hoisting shall be wire rope providing a factor of safety not less than five to one for material hoist and ten to one for personnel hoist when new, which shall be calculated by dividing the breaking strength of the wire rope as given in the manufacturer"s published tables, by the total load to be hoisted including the total weight of the wire rope in the shaft when fully let out, plus a proper allowance for impact and acceleration.

(b) Wire Rope Fastenings. Every wire rope used for hoisting shall be securely fastened at both ends and when in use shall not be fully unwound; at least three full turns shall remain on the drum so as to protect the end fastening at drum from overload. The wire rope end at the cage, skip or bucket shall be securely fastened by a properly made tapered socket joint, by an eye in the wire rope made with an oval thimble and wire rope clips, or by another method acceptable to the Division for this or similar service. If the wire rope clip method is used, the spacing and number used shall be as shown in Table - 1 for U-Bolts and in Table - 2 for Fist-Grip clips based upon using RRL or RLL wire rope, 6 x 19 or 6 x 37 Class, FC or IWRC; IPS or XIP. If Seale construction or similar large outer wire type construction in the 6 x 19 Class is to be used for sizes 1 inch and larger, add one additional clip. If a pulley (sheave) is used for turning back the wire rope, add one additional clip.

The number of clips shown also applies to rotation-resistant RRL wire rope, 8 x 19 Class, IPS, XIP, sizes 1-1/2 inch and smaller; and to rotation-resistant RRL wire rope, 19 x 7 Class, IPS, XIP (sizes 1-3/4 inch and smaller for U-Bolts and size 1-1/2 inch and smaller for Fist Grips).

(d) Splicing. Spliced wire rope shall not be used, except that the end may be attached to the load by the thimble and/or clip method, as provided in subsection (b) of this section.

(1) A safety hook, shackle or other means providing closed design protection shall form the attachment between rope and a bucket, cage, skip or load. The attachment shall be made so that the force of the hoist pull, vibration, misalignment, release of lift force, or impact will not disengage the connection. Moused or open-throat hooks with light safety latches do not meet this requirement.

(2) All wire rope fittings and connections shall be in accordance with the manufacturers" specifications and compatible with the type of wire rope used.

(g) Drum Flanges. The drum of any hoist used for hoisting shall have flanges which extend at least 2 inches radially beyond the last layer of rope when all the rope is coiled on the drum.

Maintain a record for each rope that includes the date of inspection, type of inspection, the name of the person who performed the inspection, and inspection results.

Use the "rag-and-visual" method to check for external damage. Grab the rope lightly and with a rag or cotton cloth, move the rag slowly along the wire. Broken wires will often "porcupine" (stick out) and these broken wires will snag on the rag. If the cloth catches, stop and visually assess the rope. It is also important to visually inspect the wire (without a rag). Some wire breaks will not porcupine.

Measure the rope diameter. Compare the rope diameter measurements with the original diameter. If the measurements are different, this change indicates external and/or internal rope damage.

Visually check for abrasions, corrosion, pitting, and lubrication inside the rope. Insert a marlin spike beneath two strands and rotate to lift strands and open rope.

Assess the condition of the rope at the section showing the most wear. Discard a wire rope if you find any of the following conditions:In running ropes (wound on drums or passed over sheaves), 6 or more broken wires in one rope lay length; 3 or more broken wires in one strand in one rope lay. (One rope lay is the distance necessary to complete one turn of the strand around the diameter of the rope.)

Corrosion from lack of lubrication and exposure to heat or moisture (e.g., wire rope shows signs of pitting). A fibre core rope will dry out and break at temperatures above 120°C (250°F).

Kinks from the improper installation of new rope, the sudden release of a load or knots made to shorten a rope. A kink cannot be removed without creating a weak section. Discarding kinked rope is best.

ASTM A931 is the most efficient testing method; it calculates the measured braking force, yield strength, elongation, and modulus of elasticity. Tension testing should be done on new wire ropes in most cases. Individual wire strengths can be reduced by abrasion and nicking when the wire rope is used in any application, reducing the wire rope’s strength. Damage to the outside wires reduces the maximum tensile strength achievable during tension testing.

ASTM A931 method is based on measuring the actual rope diameter and sample length then zeroing is completed. For this purpose, the maximum rate of loading should be 0.032 in. per minute. Reduction from a full reading occurs when the load is applied. When no more force can be used, the measured breaking force is attained.

Understanding the basics of wire rope will help guide you on how to choose the right wire rope for your job. Application, required strength, and environmental conditions all play a factor in determining the type of wire rope that is best for you.

But when it comes to buying wire rope, the various numbers and abbreviations that describe the different types of wire rope can be confusing. EIPS wire rope, 6X19 IWRC wire rope, and lang lay wire rope are just some of the many variations available. But what does it all mean?

Displayed as inch or fractional inch measurements, the size indicates the diameter of the rope. Industry standards measure the rope at its widest point. A wide range of sizes are available from 1/8” wire rope to 2-1/2” wire rope. Thicker sized wire rope has a higher break strength. For example, our Wire Rope has a 15,100 lb. break strength while our Wire Rope has a 228,000 lb. break strength.

The numbers indicate its construction. For example: in wire rope, as shown above the first number is the number of strands (6); the second number is how many wires make up one strand (19).

When it comes to wire rope basics, regular lay also refers to right lay or ordinary lay. This indicates that the strands pass from left to right across the rope and the wires in the rope lay in opposite direction to the lay of the strands. This type of construction is the most common and offers the widest range of applications for the rope.

This term indicates that the wires twist in the same direction as the strands. These ropes are generally more flexible and have increased wearing surface per wire than right lay ropes. Because the outside wires lie at an angle to the rope’s axis, internal stress is reduced making it more resistant to fatigue from bending. This type of rope is often used in construction, excavating, and mining applications.

Independent wire rope cores offer more support to the outer strands and have a higher resistance to crushing and heat. Independent wire rope core also has less stretch and more strength.

Many of our customers use our rope and our wire rope clips to create rope assemblies. Check out of video blog on Wire Rope Clips to Wire Rope Assemblies to learn more.

Top rails and midrails shall be at least one-quarter inch (0.6 cm) nominal diameter or thickness to prevent cuts and lacerations. If wire rope is used for top rails, it shall be flagged at not more than 6-foot intervals with high-visibility material.

Manila, plastic or synthetic rope being used for top rails or midrails shall be inspected as frequently as necessary to ensure that it continues to meet the strength requirements of paragraph (b)(3) of this section.

The maximum size of each safety net mesh opening shall not exceed 36 square inches (230 cm) nor be longer than 6 inches (15 cm) on any side, and the opening, measured center-to-center of mesh ropes or webbing, shall not be longer than 6 inches (15 cm). All mesh crossings shall be secured to prevent enlargement of the mesh opening.

Note: If the personal fall arrest system meets the criteria and protocols contained in Appendix C to subpart M, and if the system is being used by an employee having a combined person and tool weight of less than 310 pounds (140 kg), the system will be considered to be in compliance with the provisions of paragraph (d)(16) of this section. If the system is used by an employee having a combined tool and body weight of 310 pounds (140 kg) or more, then the employer must appropriately modify the criteria and protocols of the Appendix to provide proper protection for such heavier weights, or the system will not be deemed to be in compliance with the requirements of paragraph (d)(16) of this section.

When the path to a point of access is not in use, a rope, wire, chain, or other barricade, equivalent in strength and height to the warning line, shall be placed across the path at the point where the path intersects the warning line erected around the work area, or the path shall be offset such that a person cannot walk directly into the work area.

The rope, wire, or chain shall be rigged and supported in such a way that its lowest point (including sag) is no less than 34 inches (.9 m) from the walking/working surface and its highest point is no more than 39 inches (1.0 m) from the walking/working surface;

After being erected, with the rope, wire, or chain attached, stanchions shall be capable of resisting, without tipping over, a force of at least 16 pounds (71 N) applied horizontally against the stanchion, 30 inches (.8 m) above the walking/working surface, perpendicular to the warning line, and in the direction of the floor, roof, or platform edge;

The rope, wire, or chain shall have a minimum tensile strength of 500 pounds (2.22 kN), and after being attached to the stanchions, shall be capable of supporting, without breaking, the loads applied to the stanchions as prescribed in paragraph (f)(2)(iii) of this section; and

Over the past 15-20 years, compact strands and other high performance wire ropes have become increasingly popular, not to mention the plastic impregnated cores or plastic filled valley or fully plasticized wire rope options as they help protect and improve the life cycle cost of the product as long as they are right for your application.

The grade of the wire rope varies also; for example, the following types of rope are still on the market: IPS (Improve Plow Steel), EIPS (Extra Improved Plow Steel), EEIPS (Extra Extra Improved Plow Steel) and even EEEIPS (Extra Extra Extra Improved Plow Steel).

The following industries commonly use wire rope in their day-to-day operations: general construction and contracting, water main and sewer work and repair, open pit mining, underground mining, aggregate mining, steel mills, shaft sinking, oil and gas industries, engineering, crane rental, tower cranes, rail industry, steel erection, machinery movers, tow trucks and roll off truck as well as machine shops and automotive car stamping plants, communication towers, suspension bridge construction, concrete and drilling. Over the past few years, we have also seen an increase in requests for supply in the building of zip lines which is interesting, but it is important to make sure they are designed and built by a competent and responsible person.
