Endless Locking type Wire Rope Sling

No.602006

The Endless Locking Type Wire Rope Sling (6x37+IWRC) is a premium, heavy-duty lifting loop engineered for superior flexibility, exceptional durability, and efficient load handling in demanding industrial rigging environments.

  • Optimized Stress Distribution: The continuous endless loop design allows the sling to be rotated prior to each lift, preventing repetitive stress on a single point and significantly extending the sling's operational lifespan.
  • Hitch Versatility: The highly flexible 6x37+IWRC steel construction conforms perfectly to load contours, making it the ideal choice for secure and stable Choker Hitches and Basket Hitches.
  • Secure Locking Sleeve: Manufactured using a robust ferrule locking sleeve to permanently secure the continuous loop, ensuring maximum strength and safety under heavy tension.
  • Compact & Efficient: The streamlined loop design eliminates bulky end hardware found on traditional single-leg slings, allowing for easier handling, quicker rigging setups, and highly compact storage.
  • Technical Data

  • Safe Use of Wire Rope Sling

Product Features & Benefits

  • High Flexibility: Constructed from 6x37+IWRC (Independent Wire Rope Core) wire rope, offering superior flexibility compared to standard 6x19 slings, making it easier to wrap around loads.
  • Versatile Hitching: The continuous loop design is perfect for Choker Hitches and Basket Hitches, adapting tightly to the shape of irregular loads (e.g., pipes, logs, beams).
  • Extended Service Life: Unlike eye-and-eye slings that wear at fixed points, this endless sling can be rotated before each lift to distribute wear evenly across the entire body.
  • Secure Locking Splice: Features a high-efficiency Aluminum Locking Ferrule (mechanical splice) that creates a permanent, secure loop with a 5:1 Safety Factor.
  • Heavy Duty Capacity: Available in rope diameters from 10mm to 105mm, with Vertical Working Load Limits (WLL) up to 232 tons.
  • Cost-Effective: A durable, reusable alternative to single-use slings, designed for repetitive heavy lifting in construction and manufacturing.
Q: What is a "Locking Type" endless sling?
A: A "Locking Type" endless sling is formed by overlapping the wire rope ends and securing them with a compressed metal sleeve (ferrule). This mechanical splice "locks" the loop in place, ensuring high strength and safety without the risk of hand-splices unravelling.
Q: Why choose 6x37+IWRC construction for an endless sling?
A: The 6x37 construction contains more individual wires per strand than 6x19, making it significantly more flexible. This allows the sling to bend more easily around loads in choker or basket hitches without kinking.

What are Wire Rope Slings?

A wire rope sling is a type of lifting sling made of wire rope that is used to hoist heavy loads in a variety of industries, including construction, shipping, and manufacturing. It is made up of several individual strands of wire that are twisted together to form a strong, flexible rope. The wire rope sling is designed to distribute the weight of the load evenly, making it easier to lift and move.

Wire rope slings come in different types, including single-leg slings, double-leg slings, and multi-leg slings, depending on the number of legs or branches that are attached to the load. They are also available in different configurations, such as choker, basket, or vertical hitch, which affect their lifting capacity and application.

Wire rope slings are highly durable and resistant to abrasion, making them suitable for heavy lifting applications that require a high level of strength and durability. However, they should be inspected regularly for signs of wear and tear, and should only be used by trained professionals who understand their safe usage and handling procedures.

ALWAYS

  • Store and handle wire rope slings correctly.
  • Inspect wire rope slings and accessories before use and before placing into storage.
  • Follow safe slinging practices, as given overleaf.
  • Fit slings carefully, protect them from sharp edges and position hooks to face outward from the load.
  • Apply the correct mode factor for the slinging arrangement.
  • Back hook free legs to the master link.

NEVER

  • Attempt to shorten, knot or tie wire rope slings.
  • Force, hammer or wedge slings or their fittings into position.
  • Lift on the point of the hook.
  • Use wire rope slings in acidic conditions without consulting the supplier.
  • Use wire rope slings at temperatures above 100°C or below minus 40°C without consulting the supplier.
  • Shock load wire rope slings.

Selecting the Correct Sling

Wire rope slings are available in a range of sizes and assemblies. Select the slings to be used and plan the lift taking the following into account:

Type of sling to be used - endless, single, two, three or four leg.

Capacity - the sling must be both long enough and strong enough for the load and the slinging method.

Apply the mode factor for the slinging method.

For use at temperatures exceeding 100°C or below minus 40°C refer to the supplier's instructions.

Where slings may come into contact with acids or chemicals consult the supplier.

In the case of multi-leg slings the angle between the legs should not be less than 30° or exceed the maximum marked.

Multi-leg slings exert a gripping force on the load which must be taken into account; this increases as the angle between the legs increases.

Due to the possibility of sparking, the use of aluminium is restricted in certain classified atmospheres, so ensure the ferrule is suitable for such conditions.

Important Temperature Considerations

Always consult the supplier before using wire rope slings at extreme temperatures (above 100°C or below -40°C) or in environments where they may contact acids or chemicals.

Storing and Handling Wire Rope Slings

Never return damaged or contaminated slings to storage. They should be dry, clean and protected from corrosion.

Store wire rope slings on a rack and not lying on the ground. The storage area should be dry and free of any contaminants which may harm the sling.

Important

Do not alter, modify or repair a wire rope sling but refer such matters to a Competent Person.

Using Wire Rope Slings Safely

Do not attempt lifting operations unless you understand the use of the equipment, the slinging procedures and the mode factors to be applied.

Do not use defective slings or accessories.

Do not force, hammer or wedge slings or fittings into position. They must fit freely. Check to ensure correct engagement of fittings and appliances.

Position hooks of multi-leg slings facing outward from the load.

Do not lift on the point of a hook.

Ensure that the wire rope is not twisted or knotted.

Ensure the effective diameter of pins, hooks etc upon which soft eyes fit is at least 2 × the wire rope diameter.

Position the splices of endless slings in the standing part of the sling away from hooks and fittings.

Never join wire rope slings made from different lays of rope together as this will cause them to un-lay thus seriously affecting their capacity.

Back hook free legs to the masterlink to avoid lashing legs which might accidentally become engaged or otherwise become a hazard.

Take the load steadily and avoid shock loads.

Do not leave suspended loads unattended. In an emergency cordon off the area.

In-service Inspection and Maintenance

Maintenance requirements are minimal. Keep wire rope slings clean and protect from corrosion. Use non-acidic lubricants.

Regularly inspect wire rope slings and, in the event of the following defects, refer the sling to a Competent Person for thorough examination:

Defects Requiring Professional Examination:
Illegible markings
Distorted, worn or damaged fittings
Broken or cut wires
Kinks
Protrusion of core
Corrosion
Heat damage or discolouration
Signs of movement at splices and ferrules
Any other visible defect to the wire rope, thimbles or fittings

Safety First

Wire rope slings should only be used by trained professionals who understand safe usage and handling procedures. Always consult a Competent Person if you have any doubts about the condition or suitability of a sling for a particular application.
