Circular eye shaped lifting belt — The Shape of the Eye and the Shape of the Body

This article is named three ways on one page, and the three names describe the same object from different sides. Circular eye shaped describes the ends: an eye formed as a circular loop, so the hardware seats in a round opening rather than folding a flat eye over. Lifting belt with buckles at both ends describes the configuration: two loaded ends rather than one closed loop. And cylindrical sling describes the body: a tubular woven sleeve that spreads the load across a surface instead of an edge. This page takes the shape first, because the shape is what decides where the article may be used at all. HS code 630790; telephone 18066002268.

1. Three Names, One Article, and Why the Shape Comes First

The name of this article is three names in a row, and they are not synonyms: each one describes a different part of the same object. Circular eye shaped describes the ends. Lifting belt with buckles at both ends describes the configuration, which is two loaded ends rather than one closed loop. Cylindrical sling describes the body, which is a tube. Reading them as three product names is how a buyer ends up ordering the wrong article, because the three descriptions are also the three things that have to match the lift: the eye has to take the hardware, the two ends have to suit the load, and the tube has to meet the surface.

The article as supplied: a cylindrical woven body with an eye formed at each end. The photograph is this factory's own, and the caption describes what the shape is for rather than decorating the page: the round eye takes the hardware, and the tube meets the load.

The name	What it describes	The decision it carries
Circular eye shaped	An eye formed as a circular loop at the end of the article	Which fitting the eye can take, and how the load enters the article
Buckles at both ends	Two loaded ends rather than one continuous loop	Whether the lift has two points of support, or one closed loop would do
Cylindrical sling	A tubular body rather than a flat band or a wound round core	How the load is contacted: across a surface rather than across an edge

This page takes the shape first for a practical reason. Capacity is the number a buyer asks for, but at the sizes this article is made in, capacity is usually not what limits the lift: the eye that will not take the shackle, the two ends that do not match the two lifting points, or the body that cannot be dressed onto the load are the failures that actually happen. The published inputs behind a rated load include the type of hitch, the angle of loading, the diameter of curvature the sling is used over and the fabrication efficiency of the made-up article, which is four of the six inputs describing geometry and construction rather than material.

2. Why the Eye Is Circular, and What the Shape Decides

An eye is the opening the lift passes through, and its shape decides how the load enters the article. A flat eye is a fold: the opening can flatten as the hardware pulls on it, and the load then concentrates where the fold crosses itself. A circular eye is formed as a loop, so the opening keeps its shape under load and the hardware seats in the round opening with the load spread round the inside of the loop.

The shape is also what makes the published rule about eye width necessary. An object placed in the eye of a sling is not to be wider than one-third of the length of the eye. That is a rule about the eye as a shape rather than as an opening: a fitting that is too wide in the eye forces the loop apart, and the loop is then loaded in a way nobody rated, however strong the fitting is.

The eye	What the shape does under load	What it requires of the lift
Formed as a circular loop	Keeps its opening, so the hardware seats in the round rather than flattening the eye	A fitting that fits: no wider than one-third of the length of the eye
Loaded round the inside of the loop	Spreads the load round the eye instead of concentrating it at a fold	Hardware free of sharp edges, so the inside of the eye is not cut
Two eyes, one at each end	Each end is loaded through its own eye, so the two ends share the lift as the geometry dictates	A lift with two points of support, or a choker at each end
Eye sewn into the body	The seam is inside the article's rated construction, not an addition to it	Stitching as the only method of forming the eye, in an even pattern and heavy enough to develop the full breaking strength

3. The Tube: What a Cylindrical Body Changes at Contact

A flat band contacts a load along its width; a tubular body contacts it round a surface. That difference is the reason to choose this article, and it is also the reason it is not interchangeable with a flat sling of the same rated load. Where the load presents a curved or uneven face, a flat band touches it on the high points and the load sits on the low ones, which is why the published practice treats padding and protection as a requirement rather than a precaution: slings are to be padded or protected from the sharp edges of their loads.

A tube does not remove that requirement, and it should not be sold as though it does. What it changes is the contact pressure at an ordinary surface: the same load spread round a tube is spread over more of the load's surface, so the article stays where it was dressed and the load is less likely to be marked. Against a genuine edge, the rules are unchanged: protect it, or change the article.

The contact	Flat band	Cylindrical body
Against a flat face	Contacts along the band's width	Contacts round the tube, which finds its own bearing
Against a curved or uneven face	Touches the high points; the low points carry nothing	Conforms round the curve, so the load is spread over more of the surface
Against a sharp edge	Must be padded or protected	Must be padded or protected: a tube is not edge protection
Under a choker	The band folds through the eye or the choke point	The tube rolls through the choke, which is why the angle of choke matters
Where it is dressed	Stays where it is placed if the surface is even	Can roll on a smooth cylindrical load unless the choke or the dressing holds it

4. What the Eyes Require of the Hardware

The eye is the interface, and at the sizes this article is made in the interface is where a lift is usually lost. Four published requirements govern it, and none of them is advisory.

The requirement, as published	What it means on site	What it prevents
An object in the eye is not to be wider than one-third of the eye's length	Check the shackle or hook against the eye before the lift, not after the load is on	An eye forced open by a fitting that is too wide, which is the commonest interface fault
Fittings: minimum breaking strength equal to that of the sling, free of all sharp edges	Hardware is matched to the article rather than chosen for convenience; a hooked or burred surface is a defect	A fitting that cuts the inside of the eye, and a weak link nobody rated
Fittings: to sustain twice the rated load without visible permanent deformation	An overload shows as a distorted fitting before it becomes an event	Silent overload: a fitting that hides its history until it fails
Slings are not to be constricted, bunched or pinched by the load, hook or any fitting	The eye is dressed onto the hardware, not forced onto it	Concentrated loading and damage that retires the article early

5. Where This Article Is the Right Choice

Two loaded ends and a tubular body make this an article for lifts that have two points of attachment and a surface worth protecting, and it is worth being equally clear about where it is not the right answer. Where the lift wants one closed loop with no join in the load path, the round form does that job and heavy duty round sling is the page for it. Where the requirement is one band round one load, the anchor ring flat lifting strap covers the flat form. And where the load presents a contact point that needs protecting rather than a surface, the circular lifting straps page deals with the contact itself.

The lift	This article	The alternative, and why
Two attachment points, a surface worth protecting	Suits: two eyes, tubular body, load spread round the tube	A closed loop (heavy duty round sling) where one join-free load path is wanted
One band round one load	Possible, but the tube is more than the job needs	anchor ring flat lifting strap for the flat form
A load with a contact point rather than a face	The tube helps at the surface but the edge rules are unchanged	circular lifting straps for the contact and the sleeve
A choker at one or both ends	Suits: the tube rolls through the choke, and the angle of choke governs the figure	the same article read from the column for the choke, never from the vertical column

6. Marking and Identification

The identification rules are the same for this article as for any synthetic sling, and they are the reason a faded label retires an article that may be perfectly sound. Each sling is marked or coded to show the rated capacities for each type of hitch and the type of synthetic web material, the article's own marking is the figure that governs its use, and slings without affixed and legible identification are not to be used at all.

The element	What it has to carry	Why it matters here
The marking on the article	The rated capacities for each type of hitch, and the type of synthetic material	An article without legible identification is not usable, whatever its condition
The colour	The capacity step, up to the last entry, which reads ten tonnes and above	Above ten tonnes the colour marks a class rather than a value, so the label carries the figure
The length convention	Circumference of the loop, or the effective working length as used	This article has two loaded ends, so the two conventions are easy to confuse on an order
The certificate	What was tested, to what figure, and which article it names	It answers the question an auditor asks about an article that is made to order

7. The Duty Envelope: Fibre, Temperature and Chemistry

The body of this article is built from synthetic webbing, normally polyester for the working range, and the envelope is what decides whether it may be used at all. Polyester and polyamide have a published range of minus 40 to plus 100 degrees C, the guidance for synthetic slings works to 90 degrees C as the upper figure for those materials, and the regulation sets polyester and nylon at 180 degrees F, with polypropylene at 200 degrees F. Work to the lowest published figure for the material and keep the source beside it.

Chemistry is a separate exclusion rather than a margin. Nylon is not to be used where fumes, vapours, sprays, mists or liquids of acids or phenolics are present; polyester and polypropylene are not to be used where the same forms of caustics are present; and aluminium fittings are not to be used where caustics are present, which is worth checking separately because the fitting is often chosen after the sling.

The condition	The rule	The practical consequence
Heat	Polyester and polyamide to 100 degrees C as published, 90 degrees C as the guidance upper figure, 180 degrees F in the regulation	Work to the lowest figure; heat is a property of the fibre and cannot be bought with capacity
Acid	Nylon excluded where acids or phenolics are present in fume, vapour, spray, mist or liquid form	Check the atmosphere before the fibre, not after the failure
Caustic	Polyester and polypropylene excluded where caustics are present in the same forms	A caustic plant should be specifying for the chemistry rather than for the tonnage
Aluminium fittings	Excluded where caustics are present	The fitting is part of the material decision, not a separate purchase
Surface and edges	Slings are to be padded or protected from sharp edges, and not constricted, bunched or pinched	Protection travels with the article; a tube is not a substitute for it

8. Between Inspections: Removal, Repair and the Record

The article is inspected each day before use, and periodic inspections are made at intervals no greater than twelve months, with additional inspections where service conditions warrant them, judged on the frequency of use, the severity of the service, the nature of the lifts and the experience of the service life. The removal criteria are the ordinary ones for a synthetic sling, and any one of them removes the article from service immediately: acid or caustic burns, melting or charring, snags, punctures, tears or cuts, broken or worn stitching, and distortion of fittings.

Repair rules at the eye deserve a line of their own, because the eye is the part that gets damaged and the part a site is most tempted to fix. A load-bearing splice is not repaired and temporary repairs are prohibited. Repairs belong to the manufacturer or an equivalent entity, and the article returns to service only after a proof test to twice its rated capacity, with the certificate retained and available for examination and the repair marked to identify who made it. The heavy duty round sling class page sets out where that puts this family against the chain family, where the same article can be repaired and re-tested instead of retired.

3	The hardware that will sit in each eye	The one-third rule on eye width, and whether the fittings seat properly
4	The length, and which convention is meant	The working length as used, rather than the length as woven
5	The environment: temperature, chemistry, wet or dry	The fibre, and the fittings as well as the body
6	The marking and the documents the site has to hold	What the label says, and what is kept in the file afterwards

10. Frequently Asked Questions

Q1: What does circular eye shaped mean?

It describes the ends: the eye is formed as a circular loop, so the hardware seats in a round opening instead of folding a flat eye over and concentrating the load at the fold.

Q2: Is this the same as a round sling?

No. A round sling is a closed loop with no join in the load path; this article has two loaded ends and its body is a tube. The two are chosen for different lifts, and the round form is covered on its own page.

Q3: How wide may the shackle be in the eye?

An object placed in the eye of a sling is not to be wider than one-third of the length of the eye. Beyond that the loop is forced open and the eye is loaded in a way the rated configuration does not describe.

Q4: Is a cylindrical body the same as edge protection?

No. A tube spreads the load round a surface, which reduces marking and contact pressure, but slings are still to be padded or protected from the sharp edges of their loads. A tube is not a substitute for protection.

Q5: What are the fittings rated to?

A fitting has to have a minimum breaking strength equal to that of the sling, be free of all sharp edges, and sustain twice the rated load without visible permanent deformation.

Q6: Can it be used as a choker?

Yes, from the column for the choke, and the rating of a choker is valid provided the angle of choke is 120 degrees or more. Below that the figure comes from the manufacturer.

Q7: How often must it be inspected?

Each day before use, with periodic inspections at intervals no greater than twelve months and additional inspections where service conditions warrant, judged on the frequency of use, the severity of the service, the nature of the lifts and the experience of the service life.

Q8: The label is illegible. Can the article be used?

No. Slings without affixed and legible identification are not to be used at all: the marking is the figure that governs the lift.

Q9: Can a damaged eye be repaired?

A load-bearing splice is not repaired and temporary repairs are prohibited. Repairs are made by the manufacturer or an equivalent entity, and the article returns to service only after a proof test to twice its rated capacity with the certificate retained.

Q10: What temperature can it work at?

For polyester and polyamide, minus 40 to plus 100 degrees C as published, 90 degrees C as the upper figure in the guidance for synthetic slings, and 180 degrees F in the regulation. Work to the lowest published figure and keep the source with it.
