WIRE ROPE

Wire rope typically is composed of three components; (1) the core around which the rope is constructed; (2) the individual wires that form strands; and, (3) the strands themselves. All of the components are designed and built to move and interact with one another to give the finished product the attributes of strength, flexibility, resistance to abrasion, and resistance to rotation appropriate for a particular job.

Wire rope is generally grouped into different classes based on the number of individual strands, as well as the number of wires in each strand, e.g. 6×7, 6×19, 8×19, 19×7, etc. These classifications are somewhat misleading, however, as they do not always represent the actual number of wires in a given strand. For example, wire rope with actual construction using 6 strands of 21 wires each, 6 strands of 25 wires each, and 6 strands of 26 wires each are all included in the 6×19 classification. Illustrations of some of the more typical wire rope classifications are below.

Within the various classifications, wire rope can be further broken down into factors such as left or right lay, bright or galvanized finish, regular or Lang lay, each of which factors give the finished product different strengths and compromises. THE GOOD NEWS FOR INTEGRICERT CUSTOMERS IS THAT WE HAVE THE EXPERTISE AND EXPERIENCE TO PROVIDE YOU WITH THE RIGHT PRODUCT TO YOU’RE YOUR NEEDS. IntegriCert offers our customers a wide range of top quality wire rope. All of our wire rope has mill test documentation including working load limit, construction and actual break tests (strength tests). Our wire rope can be used in numerous applications including hoisting and boom lines for cranes, wire rope sling fabrication, tow lines, rotary drill lines, tubing lines, sand lines, winch lines, mooring lines, and specialized plastic infused ropes for the mining industry.

    Alternate Lay, sometimes referred to as reverse lay, is a stranded rope where the type of lay of the outer strands is alternately regular lay followed by Lang lay such that three of the outer strands are regular lay and three are Lang lay. Alternate lay wire rope has the extra flexibility of Lang lay in combination with the structural stability of regular lay. It unites the best features of both types of wire rope. Alternate lay is made with relatively large outer wires to provide increased resistance to abrasion when scrubbing against sheaves and drums. Finer inside wires and flexibility enable alternate lay ropes to absorb severe bending stresses. It is well suited to winding applications where abrasion and crushing can occur. Alternate lay wire rope applications include boom hoists and numerous types of excavating equipment like clamshells, shovels, cranes, winches and scrapers.

WIRE ROPE SLINGS

IntegriCert offers a wide variety of wire rope slings, from 1/8” to 4” in diameter. All of our wire rope slings are proof tested to twice the safe working load limit upon fabrication or repair. In addition, all wire rope slings fabricated by IntegriCert are channeled through an extensive quality control system that meets ISO standards. Our wire rope slings are used on a daily basis for lifting objects such as cargo transit containers and offshore service equipment or for any subsea lifting application – as well as the installation of oilfield drilling platforms.

  • DNV GL (Det Norske Veritas), through its Business Assurance division, is widely recognized as a world-wide authority in the development and certification of quality standards and processes. In order to promote safe, reliable and enhanced performance in projects and operations involving the oil and gas industry, DNV has developed various standards such as 2.7.1 for Offshore Containers and 2.7.3 related to Portable Offshore Units. Equipment built to these exacting standards is readily accepted for use in markets around the globe. IntegriCert is one of a very few domestic companies certified and approved to fabricate, repair and re-certify wire rope slings or lifting sets that are in compliance with these standards.

    In recognition of the increased safety value provided by DNV’s standards, some of the most active companies in the Gulf of Mexico are now requiring that products used within their facilities and offshore platforms must meet these standards. In order to meet 2.7.1, a sling or lifting set must conform to each of the following:

    1. Each component, including the wire rope and all end-terminations, must be certified to meet the standard;
    2. The lifting set must be designed to perform with the required working load, increased by the appropriate enhancement factor;
      1. The minimum allowable working load limit is 7.7 tons;
      2. Enhancement factors increase as weight decreases due to the higher potential for a load to swing;
    3. The lifting set must be fabricated by a rigging shop with a quality process designed and certified to assure fabrication and re-certification in accordance with the procedure;
    4. A Certificate of Compliance (“COC”) must be issued and maintained on each component used in the lifting set; and,
    5. A special DNV approved tag, designating the sling as having been fabricated in accordance with DNV’s procedure, must be affixed to and remain a permanent part of the lifting set.

    IntegriCert has received DNV Type Approval at all three of our locations, and can therefore meet all your requirements for DNV slings from whichever location most efficiently meets your needs.

  • This type of sling consists of one single part of wire rope with a mechanically spliced terminated end fitting. Various types of end fittings can be attached, including a thimble eye, standard soft eye, closed or open spelter socket, closed or open swage socket, swaged ferrule, eye hoist hook or swivel hook. These slings are commonly used to connect to one lifting point.
