wire rope lifting sling factory

Wire rope slings are widely used in the lifting applications and engineering industries for extremely heavy loading. They can be used on wire rope hoist, pulley and block, crane and winch pulling equipment at dockyards and large construction sites.

They are available in single leg or multi legs like the chain slings, however, the wire rope slings are more safety than chain slings for wire rope sling can still hold the load if 1 or 2 wires are broken, while the chain sling will fail for 1 link broken result to the whole chain sling failed.

Usually, we use a less flexible or a stiffer wire rope to assembly for they are more crush and abrasion resistance than a very flexible one since wire rope slings are used in a straight line for lifting connect with a master link on one end and a hook or hooks on the other end, need more load strength than flexibility.

In the case of the "U" shaped sling, lifting is accomplished by firmly attaching the eyes to a hook or hoist, though both ends are then simultaneously lifted in order to wrap around or cradle the supplies or finished goods to be lifted.

Unlike synthetic or fiber slings, wire rope offers increased resistance to wear and abrasion and can be used for both hot and cold materials as well as in corrosive applications such as those in marine, construction, aerospace, manufacturing, assembly, transport, shipping, and other industries where wire rope slings are commonly used. Wire ropes fitted with slings in these applications also serve to improve connectivity and prevent fraying of the rope.

Like stranded wire ropes, the slings that they attach too are strictly regulated and must be inspected regularly as mechanical failure puts both machinery and employees at serious risk. To prevent such disruptions, it is important to select the proper sling for a given application.

Slings are most commonly constructed simply by looping or folding the end of a wire rope back onto itself and holding it in place with a firm fitting such as a clamp. Alternatively, the folded segment of wire may be braided or twisted along the main body of rope and otherwise held in place through welding or similar processes.

The rope itself is comprised of cold drawn filaments that are twisted or braided into strands which in turn are helically wrapped around a core. The multilayered formation of wire rope acts as a safety measure as individual strands are more likely to fail than the rope as a whole, allowing the other strands to act as a backup.

Popular materials for wire rope and sling construction include aluminum, nickel alloy, bronze, copper, and titanium, although steel and stainless steel are the most common due to their increased strength and availability.

Additional considerations include the wire rope sling"s dimensions, fatigue strength, its ability to bend without distortion, to withstand abrasion, and environmental conditions as well as the intended use for the sling.

Wire rope slings have been used extensively for years and were once the industrial lifting sling of choice. Wire rope slings, sometimes referred to as wire cable slings are more robust and durable than nylon slings and also have higher temperature limits.

Wire rope slings with an independent wire rope core (IWRC) can withstand contact and exposure temperatures up to 400 degrees (F). Wire cable slings with fiber cores should never be exposed to temperatures in excess of 180 degrees (F). Wire rope slings of all types should never be used at temperatures below -40 degrees (F). Wire rope rigging slings with fiber cores (FC) are rated at reduced capacities when compared with an equivalent size, wire choker with an independent wire rope core (IWRC). They are generally fabricated from 6 x 19 or 6 x 37 construction wire cable. The constructional numbers refer to the number of strands (6) that are helically wound around a core. The core supports the strands of the wire rope lifting sling and can either be an independent wire rope core (IWRC) or a fiber core (FC) made from hemp or sisal. Smaller diameter wire rope slings feature 6 strands with 19 wires in each strand. Larger diameter industrial lifting slings will generally feature 6 strands with 37 individual wires in each strand. The 6 x 37 construction is more flexible than the 6 x 19 construction, but not as abrasion resistant.

Wire cable lifting slings used by the crane, rigging and material handling industries are available in many different styles and constructions to meet your needs. Custom made slings and special order slings are shipped daily from our factory. The most popular wire lifting slings are Single Body slings featuring a 6 x 19 or 6 x 37 Construction, Extra Improved Plow Steel (EIPS) Wire Rope with an Independent Wire Rope Core (IWRC). These slings are sometimes referred to as wire chokers, Permaloc wire rope slings, wire cable slings, Flemish eye slings, single leg slings, eye and eye slings or eye & eye slings due to the loop or eye that is formed on each end of the wire sling.

There are different grades and strengths of steel used to manufacture the individual wires that make up the sling. The most popular for sling fabrication is (EIPS). Metallurgists continue to improve the tensile properties of steel with new, corresponding designations such as EEIPS (Extra-Extra Improved Plow Steel). Single leg, Flemish Eye/Mechanical Splice, Wire Slings provide additional security, superior to return loop wire slings should the swage sleeve become damaged during use. Single Body Wire Cable slings are available in 15 different types which feature different combinations of plain loops, three types of thimbles (crescent, standard and slip through) and rigging hooks. Thimbles greatly improve sling longevity by protecting the rope at connection points. We offer two types of single leg wire slings that feature a sliding choker hook that is placed between the sling eyes. Industrial lifting slings with sliding choker hooks make removal of the cable sling from the load, quick and easy. Type 14 lifting slings feature a lifting loop on one end and a thimble on the opposite end to engage the sliding choker hook. Type 15 lifting slings features plain loops each end. View the 15 single leg wire sling types available .

We will not sell you a sliding choker hook without a hook latch, but there are many that will! Stainless Steel Wire Rope Slings provide the sling user with improved corrosion resistance and are also readily available. Cable Laid Wire Rope Slings with a galvanized finish are also available. Cable Laid Wire Slings are much more flexible than equivalent sized, single body wire slings. The flexibility of industrial lifting slings that feature a cable laid construction is a direct result of the small diameter, aircraft cable used in the fabrication of the wire sling. Size for size, cable laid lifting slings are not as strong as equivalent sized, single body, wire chokers. Cable laid wire slings can be equipped with many of the same options available for single body slings.

In addition to our standard lifting slings, custom made slings are also readily available. Cable laid slings are also referred to as Ultra flexible cable laid slings, steel strand and E-Z Flex Cable Laid wire rope slings. Wire Rope Bridle Slings are available in two leg bridle, three leg bridle and four leg bridle designs. A master link is used to collect the multiple wire cable sling legs, while providing a connection point to the hoist line. Bottom “connectors” such as masterlinks or eye hoist hooks (with latches) are most commonly used to engage the load. Custom made bridle slings are also readily available.

In addition to wire bridles we also offer a complete line of strand laid grommets and swaged socket assemblies. Slingmax® Wire Rope Slings are as revolutionary to wire cable slings as Twin-Path® Extra, high performance fiber slings are to polyester roundslings. That makes sense, because both products are patented inventions from the mind of Dennis St. Germain, Sr. Without a doubt, Mr. St. Germain has done more for the sling, crane and rigging industries than any other. It all started years ago with the Tri-Flex® Sling which provides professional riggers with a great combination of strength and flexibility. Tri-Flex® wire rope slings provide substantial savings due to the materials used and the tremendous labor savings realized in the fabrication process. Tri-Flex® cable slings were also the genesis of T&D Ultra-Flex® slings which are used extensively in the power generation, transmission and distribution industries.

Gator-Laid® wire rope slings and Gator-Max® wire cable slings are the most efficient, heavy lift slings available. Both the Gator-Laid® wire slings and Gator-Max® lifting slings feature 12 parts of wire in the sling eye and meet all the requirements of the Wire Rope Technical Board and the United States Navy. Gator-Flex® wire rope slings and Gator-Flex® wire rope grommets are heavy lift slings used extensively by the oil and gas industries for both land based and off shore rigging. Gator-Flex® wire slings offer sling users the greatest flexibility available for a heavy lifting sling. Gator-Flex® grommets not only provide flexibility, but can be fabricated for applications requiring minimum sling lengths.

Like all of our nylon web slings and polyester round slings, wire rope slings need to be inspected on a regular basis to ensure the safety of sling users. Poor inspection practices can lead to devastation, injury and death. Please refer to the inspection and usage information that is available in our Rigging Resource Guide or on our web site. Read and understand the warnings that accompany all our products. Remember, ignore a warning leads to much mourning.

All wire chokers shipped from Lift-It have a heavy duty, metal sling tag attached. There is no additional charge for this as we have always felt it is our duty to provide robust sling tags. Others may use cloth or synthetic materials which sometimes come off the sling, before it’s even used! Others fill in the information with magic marker that is not so magic. The tag is just as important as the wire cable, the way the Flemish eye is fabricated and the way the mechanical sleeve is swaged. If a vendor wants to charge you extra for a metal tag, run as fast and as far as you can from them and contact the sling experts at Lift-It Manufacturing, where profit margins are not maximized by supplying labels that should be used on clothing.

While wire cable slings are more robust and durable than nylon lifting slings or polyester roundslings, wire slings are not cut proof. Wire slings need to be protected from damage like all industrial lifting slings. Only materials of sufficient strength, thickness and construction must be used to prevent damage. Do not use gloves or cardboard. Use protection devices that have been designed to resist the effects of cutting and abrasion. Wire Rope Saddle Protectors are readily available; Click Here

Wire rope slings are extremely strong and an excellent choice for heavy duty jobs involving not only lifting, but also hoisting, towing, or anchoring loads. The fabrication of wire slings also offers excellent abrasion-resistance and heat resistance so it can be used in extreme conditions and temperatures. Its pliable design can conform to the shape of a load for a more secure application.

Wire rope slings are manufactured in a variety of configurations, with 6x19 and 6x36, being two of the most common. The numbers represent the number of wires making up the strand and the number of strands wrapped around the core. For example, a 6x19 indicates that there are 19 wires making up a strand, and 6 strands are wrapped around the core.

Each steel wire rope configuration will offer different benefits and will be better suited to certain applications. In general, a smaller number of large outer wires offers better wear and corrosion resistance, while a larger number of small wires provides a better level of flexibility and fatigue resistance.

We offer steel wire rope slings in both 6x19 and 6x36 configurations, depending on the diameter of the wire rope. All are in a bright (unfinished) wire rope, but other configurations are available by request. Our cable laid slings are manufactured in a 7x7x7 galvanized wire rope (composed of 7 strands of 7x7 cables), which make them extremely flexible and useful for more specialized applications.

The eye loops on our sling cable are created with a Flemish splice, which is a mechanical splice where the rope cable is separated into two parts (one part has three strands, the other part has the remaining three strands plus the core), then re-laid back in the opposite direction to form the loop. The ends are then secured with a carbon steel sleeve around the entire area. Flemish splices offer the most efficient use of capacity.

The core of the wire rope used in cable slings can be made of several different materials, including steel or natural fibers. Our steel wire rope slings are made with Extra Improved Plowed Steel (EIPS) around an Independent Wire Rope Core (IWRC) for the ultimate in strength and durability.

Our categories of wire rope slings are broken down by number of legs, hardware, and the diameter of the wire rope. Each wire sling is made to order, so custom slings are also always an option if you don"t see what you"re looking for here.

We offer a wide selection of both domestic wire rope slings and import wire rope slings online, with additional options and customization available by calling our sales team.

Import slings are a more cost-effective choice yet offer the same wire rope strength and working load limits as our domestic slings. Our imported slings also feature sleeve components from Crosby. Wire rope slings we import are also available in custom configurations.

Sometimes called eye & eye slings because of an oval "eye" at each end, these 1 leg cable slings are rugged and reliable and a very popular choice among wire slings. The eyes are formed using a Flemish eye splice and secured with a carbon steel sleeve.

Single leg cable slings are available in a variety of styles: Eye & Thimble, Thimble & Thimble, Eye & Hook, Eye & Eye, Sliding Choker, and Cable Laid.

Also known as a 2 leg bridle sling, this sling offers increased versatility over a sling with just a single leg. Manufactured with a Flemish eye that"s spliced with a carbon steel sleeve; end options range from a latched eye hook to a simple eye design. Our 2 leg wire rope slings are available in seven different diameters of rope. Custom options are also an option.

Our 3 leg wire rope slings are also known in the industry as a 3 leg bridle sling. Each is manufactured with a Flemish eye that"s spliced with a carbon steel sleeve for the ultimate in safety and strength. End options include latched eye hooks, eyes equipped with thimbles, and more, as customized options are always available. Our 3 leg wire rope slings are available in seven different diameters of rope.

A 4 leg bridle sling offers the ultimate in versatility. Also known in the industry as wire rope 4 leg bridle slings, ours are manufactured with a Flemish eye that"s spliced with a carbon steel sleeve for an extra measure of security. And because legs can be fitted with hardware of your choosing, from simple eye formations to heavy duty hooks, it results in a sling customized to your exact application needs. Our 4 leg wire rope slings are available in six different diameters of rope.

Braided wire rope slings are formed when multiple wire ropes are braided continuously to form the body of the sling and the eye/eyes into a single fabricated sling. Braided wire slings are excellent for higher capacity lifts and can be either round or flat. One benefit of a braided sling is its ability to conform snugly to a load that"s in a choker hitch. Because of the braided design, they also are better resistant to kinking.

Our braided wire rope slings are made in the USA and available in a variety of configurations, including a 3-part braid, 6-part braid, 8-part braid, and 9-part braid. Several style options are also available, including standard eyes, thimble eyes, and more, to create a customized braided wire rope sling to your specifications.

Wire rope bridles are measured by the length of the sling leg plus the end hook. The length of the oblong master should not be included in the overall measurement.

Our slings are available in a variety of lengths, but can also be customized to any length you need. Give our sales team a call for more information or to place a custom order.

"Slings in contact with edges, corners, protrusions, or abrasive surfaces shall be protected with a material of sufficient strength, thickness, and construction to prevent damage."- ASME B30.9 (2021) 9-5.10.4(d)

All of our slings are inspected, certified and tagged with metal tags displaying rated capacities by hitch types and angles; diameter or size; and name/trademark of the manufacturer.

Proof testing certificates can be supplied with your order for a nominal fee and must be requested at the time of order. Proof tests are performed in the factory where the sling is pull tested to 2x the vertical rating and officially recorded as proof for governing bodies. During the standard manufacturing process, only random slings during a production run are tested for compliance; in order to provide proof testing certificates with your order, every sling must be pull tested at the time of manufacture.

If steel wire rope slings are not the best choice for your application, we also offer chain slings, nylon lifting slings, and polyester round slings in a wide range of styles and capacities. As with all of our lifting slings, customization is always an option.

If you need help selecting a sling, check out our How to Choose a Lifting Sling page or call our product specialists . They"ll be happy to any answer questions you may have and can even place a custom order if needed.

Domestic steel slings are available in two main configurations, 6x19 and 6x36, depending on the diameter of the wire rope. The numbers represent the number of wires making up the strand and the number of strands wrapped around the core. For example, a 6x19 indicates that there are 19 wires making up a strand, and 6 strands are wrapped around the core.

When choosing domestic cable slings, keep in mind that a smaller number of large outer wires will offer excellent resistance to general wear and corrosion; whereas a larger number of small wires will provide better flexibility and resistance to fatigue.

The core of the wire rope used in cable slings can be made of several different materials, including steel or natural fibers. Our domestic wire rope slings are made with Extra Improved Plowed Steel (EIPS) around an Independent Wire Rope Core (IWRC) for the ultimate in strength and durability.

All of our steel wire rope slings are inspected, certified, and marked with metal tags with the wire rope diameter or size and the name / trademark of the manufacturer. The tags also display rated capacities by hitch types and angles.

All of our made-in-the-USA wire rope slings are manufactured with a Flemish splice to create the eye loops. A Flemish splice is a mechanical splice where the wire rope is separated into two parts (one part has three strands, the other part has the remaining three strands plus the core), then re-laid back in the opposite direction to form an open loop (“eye”). The ends are then secured with a carbon steel sleeve around the entire area. Flemish splices offer the most efficient use of capacity.

Also known as a 2 leg bridle sling, this lift sling offers more versatility than a single leg sling, as well as increased load balance. Ours are manufactured with a latched eye hook on each end and are available in several different diameters of rope.

A sliding choker sling features a hook between the two eyes that slides from one end to the other for easy hook-up. Sliding choker slings are manufactured with a regular eye on one end and a thimble eye on the end of the sling that loops back to attach to the sliding hook.

When measuring a domestic wire rope sling with multiple legs, do not include the oblong master - instead, measure the length of the sling leg to the loadbearing point of the hook or eye.

If you need proof testing certificates for your wire rope slings, please request them at the time of order. Available for a nominal fee, these tests are performed in the factory for reliable results. Each sling is pull-tested to 2x the vertical rating, then the results are officially recorded as proof for governing bodies.

This differs from the standard manufacturing process in that every sling is pull-tested at the time of manufacture. Normally, only random slings during a production run are tested for compliance.

If domestic wire rope lifting slings are not the best choice for your job, we also offer chain slings, nylon lifting slings, high performance round slings, plasma slings, and polyester round slings in a wide range of styles and capacities.
