According to the unified international DIN standard, EN standards, load-lifting polyester tape for textile slings is marked with the same color all over the world, depending on its load-carrying capacity. Sling with a lifting capacity of 1.0 tons - must be purple, lifting capacity 2 tons. – green, capacity 3.0 tons. – yellow, etc. Slings with a lifting capacity of 10.0 tons. and above - always orange and nothing else!
White slings means that the slings are disposable (one way sling), life cycle which are designed for 2 – 5 loading operations. Such slings are classified as packaging material, which accompanies the slung cargo throughout the entire period of its transshipment and transportation from the Seller to the Buyer. After unloading the cargo at the final destination, such slings must be removed and disposed of.
Therefore, if you are offered to sell slings of some other colors, think carefully!
2. What is the narrowest/widest tape used for sewing slings and what is the maximum load capacity of tape slings?
For sewing lifting belt slings, tapes in the following widths are used: 30 – 300 mm. Naturally, the narrower the tape, the less carrying capacity of the sling will be. Typically, the width of the tape is 30 - 50 mm is monochromatic and painted in purple, as stated in clause 1 this section. Accordingly, the tape 60 - 65 mm is two-tone and will be green, the tape width 85 – 100 mm– three-tone, yellow, etc.
When using orange tape with a maximum width of 300 mm, you can sew a sling with a lifting capacity of 25.0 tons.
3. Do textile slings stretch?
Yes. Since textile slings are synthetic and made from polyester fibers, they are slightly stretchable. Question: how much? The stretch can be considered minimal, since with a working load on the sling, its elongation does not exceed 3% and not visually noticeable.
4. What is the safety margin of a textile sling?
Manufacturers can use weaving machines to produce ribbons of varying widths and tensile strengths. Accordingly, in the world there are slings with safety margins 5:1, 6:1, 7:1, 8:1 . In Ukraine, it is legally permitted to manufacture and operate slings on a synthetic basis with a safety margin of at least 7:1 . In some countries this threshold is lower.
In essence, the safety factor means the ratio of the breaking load of the sling to the working load. Those. lifting capacity sling 3.0 tons will break at a critical load of at least 21.0 tons.
It is definitely worth noting that when speaking in general about tape textile slings and breaking loads, we always mean slings that are sewn with a conventional ring, i.e. in two layers of tape according to a specific algorithm.
Attention! If you are offered single-layer slings, to put it mildly, you are being deceived!
5. What are the restrictions on the use of textile slings?
Textile slings cannot be used in hot industries. Near the springs high temperatures the lines may melt. However, such slings are not susceptible to exposure to ultraviolet radiation and direct sunlight.
Also, textile slings are not recommended for slinging loads with sharp edges, since under load the sling can be seriously deformed, which can lead to complete rupture of the sling. At the same time, there are a lot of protective covers, overlays, and corners that protect the slings from cuts and, if installed correctly, will significantly protect the slings from increased wear.
6. How do you know when it’s time to take the sling out of service? Tell us about the culling rules/norms?
Safety regulations require slingers to inspect slings before using them. During continuous operation, slings must be rejected regularly, and the inspection results must be recorded in a log. Engineering personnel responsible for maintaining lifting mechanisms in working order must inspect lifting slings every 10 days. When slings are rarely used, inspection is carried out immediately before use.
When inspecting slings, it is necessary to pay attention to the condition of the tapes, hooks, hangers, locking devices, carabiner clips and places of their attachment.
If any of the following defects are present, textile slings manufactured in accordance with the standards DSTU-EN 1492-1:2014 or TUU 29.2-21674530:011-2006 must be immediately removed from service or replaced, because their subsequent operation is unsafe:
- The tag on the sling is torn/missing technical information;
- The details/information about the sling are not readable on the tag;
- The presence of nodes on the load-bearing body of the sling;
- Presence of transverse cuts or tears in the tape;
- The presence of longitudinal cuts or tears in the tape, the total length of which exceeds 10% of the total length of the sling tape;
- Presence of single longitudinal tears/cuts more than 50 mm long;
- The presence of local delaminations of sling strips with a total length of more than 0.5 m on one extreme or two or more internal seams(when three or more seam lines are torn);
- The presence of local delamination of sling tapes in places where the edges of the tape are sealed for a length of more than 0.2 m on one extreme or two or more internal seams (when three or more seam lines are torn).
- The presence of peeling of the edge of the tape or stitching of the tapes at the loop for a length of more than 10% of the length of the seal (stitching) of the ends of the tapes;
- The presence of surface thread breaks with a total length of more than 10% of the tape width caused by mechanical impact(friction) on the sharp edges of the load;
- Presence of damage to the belts from exposure to chemicals in the form of acids, alkalis, solvents, petroleum products, etc. the total length is more than 10% of the width and/or length of the sling.
- Presence of single damage caused by chemical substances longer than 50 mm;
- The presence of bulging of threads from the sling tape at a distance of more than 10% of the tape width;
- The presence of through holes with a diameter of more than 10% of the width of the tape from the impact of sharp objects;
- The presence of burnt through holes with a diameter of more than 10% of the width of the sling strip from exposure to splashes of molten metal or the presence of more than three holes with a distance between them of less than 10% of the strip width, regardless of the diameter of the holes;
- Presence of belt contamination with petroleum products, resins, paints, cement, soil, etc. more than 50% of the sling length;
- The presence of delaminations in the structural threads of the sling tapes.
On the rigging elements of a textile sling (links, hooks, hangers) the following is unacceptable:
- Cracks of any size, delamination, tears and hairlines;
- Surface wear. The presence of dents, which led to a decrease in the cross-sectional area of the sling element by 10% or more;
- Deformations leading to a change in the dimensions of the sling element by more than 3%;
- Damage to the fastenings of rigging elements and threaded connections;
7. How can we protect textile slings and extend their service life?
SKIF INVEST LLC offers a range of rubber pads, plastic corner protectors, PVC covers of various widths, with which you can significantly extend the service life of your textile slings. The managers of our company will help you select the appropriate accessories. However, we hope for your understanding that slings are still consumables and they cannot be eternal.
8. How to determine the load capacity of textile slings?
The load capacity of textile slings can be determined in several ways:
- According to the color of the lifting belt, from which they are sewn (we talked about this in more detail in paragraph 1 of this section);
- By the number of black stripes on the tape, from which they are sewn (1 line = 1 ton);
- According to the information on the sling tag, which is sewn into one of the loops of the sling;
- According to the load capacity marking on the body of the sling itself, which the SKIF INVEST company additionally applies in a special way. By the way, let’s say that it is this additional marking that visually distinguishes the slings produced by our company from other manufacturers. We are the only ones on the market who apply such markings and do it free of charge.
- According to the width of the tape, if you have in front of you a fairly worn sling that has long lost the above identification signs.
9. Does the load capacity of a textile sling vary depending on the slinging method?
Yes, of course it changes. When slinging loads, it is advisable for the slinger to know and take into account the decreasing/increasing coefficients for changing the load-carrying capacity of the slings. For example, when slinging a load “in a girth”, the load capacity of the sling doubles, and when slinging “in a noose” it decreases by 20%. Also, it is worth noting that all this applies equally to working with rope slings.
You can find out more clearly about the dependence of the load-carrying capacity of slings on the slinging method at the end of the page on our website.
10. Is there any technical information on the textile sling?
According to international standards EN 1492-1 and EN 1492-2, each textile sling, whether tape or round, must have a PVC tag sewn into one of its loops - a tag with technical information. The tag must indicate the following information: type (design) of the sling, its load capacity, production and testing dates, manufacturer or its trademark, serial number according to the manufacturer’s accounting system, compliance standard. Also, the tag may contain additional and non- mandatory information: sling length, sketches of slinging methods with coefficients, material from which the sling is made, etc.
We emphasize that according to the same EN standards, the color of the tag is also regulated. To everyone synthetic material(polypropylene, polyester, polyamide) from which textile slings are allowed to be made has its own tag color. In our case, we make slings from polyester tape and sew in a tag of the appropriate blue color. The SKIF INVEST company is probably the only enterprise in Ukraine that strictly adheres to this requirement.
11. How are the sling loops protected from increased wear?
In the standard version, we additionally cover the loops (goons) of textile slings with a special protective fabric.
12. Is it possible to increase the load capacity of textile slings without increasing the width of the belt?
Yes, it is possible, but no more than 2 times. This is achieved by sewing the sling not in two layers, but in four. In other words, if you need a sling with a lifting capacity of 4.0 tons, but for some reason you are not satisfied with the standard 120 mm sling width, we will make a sling from a 2-ton tape with a width of 60 mm, but it will be sewn in four layer. Our managers will advise you in more detail about this.
13. I'm afraid to buy textile slings. Can you convince me of my fears?
We understand your doubts. Indeed, looking at a textile sling, it is sometimes difficult to believe that a textile tape can withstand significant loads. However, we want to assure you that synthetic slings are much more effective than their direct competitor - rope slings. The advantages of textile slings are obvious:
- slings have low own weight;
- the slings are compact and easy to fold;
- resistant to geometric deformations, do not have spring properties;
- resistant to most chemicals and does not rust;
- are not traumatic, unlike rope slings, since they do not have protruding sharp ends;
- have the largest safety factor of 7:1 compared to other types of slings.
It is thanks to the properties described above that textile slings have been the most popular type of slings all over the world for several decades.
14. Is the textile sling repairable?
No. Such slings have a stitched construction made of whole piece the tape and, unfortunately, if it is damaged (cut, puncture, delamination, etc.), it is extremely unsafe to repair, let alone work with, such a sling.

Textile tape slings are universal, durable products for lifting loads. Made from durable polyester material. Load capacity up to 30 tons. They are characterized by a high degree of reliability and are widely used in different areas for carrying and transporting goods.
Last decade textile sling and tensioning straps made of polyester, artificial material increased strength, have made a real revolution in the field of cargo equipment. With a width of 30 to 300 mm and a corresponding load capacity of 0.5 to 15 tons, lightweight, flexible and frost-resistant textile slings are widely used in everyday life.
In connection with the automobile boom in our country, a textile sling complete with rigging brackets and hooks of the S320 type appealed to Camel Trophy lovers. When conducting collective leisure activities to overcome off-road conditions, each owner of an SUV has a ribbon tow rope with a lifting capacity of 2 or 3 tons and a length of 5-6 meters in the trunk. With a 7:1 safety factor, this accessory provides reliable towing for almost any vehicle. passenger car. Many fans wildlife install on the power bumper a manual or electric winch with a reeving tow rope assembly. For this purpose, a galvanized rope with a diameter of up to 10 mm with a hook is usually used, or an “endless” cargo belt with a loop at the end is wound onto the winch drum. In addition, textile slings turned out to be indispensable when installing pipes with an insulating coating and during loading and unloading operations of any equipment with a “delicate” surface ( paint coating cars, yachts and boats, etc.)
And thanks to their low wear and ease of adjustment, tie-down straps and textile slings have become universal remedy for securing cargo both outdoors and inside warehouse complexes.

3. SAFETY PRECAUTIONS
3.1 When using slings, you should be guided by the “Rules for the design and safe operation of load-lifting cranes” (PB 10-382-00).
3.2 Owners of removable lifting devices are required to ensure that they are kept in good condition and safe working conditions by organizing proper inspection, supervision and maintenance in accordance with the requirements of safety regulations.
3.3 Before starting work, slings are subject to visual inspection.
3.4 Removable load-handling devices that have not passed inspection and technical certification are not allowed to work.
3.5 Loads must be slinged in accordance with safe slinging schemes. To sling a load intended for lifting, slings must be used that correspond to the weight and nature of the load being lifted, taking into account the number of branches and their angle of inclination; general purpose slings should be selected so that the angle between the branches does not exceed 120 °.
3.6 The connection of the lifting machine hook with the suspensions and sling loops must be reliable. The sling suspension must be secured with a hook lock.
3.7 In order to prevent loads from falling during lifting and moving them by cranes, the following slinging rules should be observed:
when tying the load, the slings must be applied without knots or twists;
It is necessary to place pads under sharp corners of loads. In this case, it is necessary to take into account the location of the center of gravity of the load;
the sling should be placed under the load in such a way as to prevent the possibility of it slipping while lifting the load;
The load must be tied in such a way that during its movement, the fall of its individual parts is prevented and a stable position of the load is ensured during movement. To do this, slinging of long loads (pillars, pipes) must be done in at least two places;
the ends of the multi-branch sling that are not used for hooking must be strengthened so that when moving the load by crane, the possibility of touching objects encountered along the way is excluded;
on the cargo reloaded with slings, in places of contact with the slings there should be no nicks or sharp edges that could damage the sling tape. The radius of the edges is not allowed to be less than the thickness of the sling tape;
the working surfaces of the hook of the lifting machine must prevent damage to the sling, have no sharp edges, the radius of curvature of the surface in direct contact with the sling must be at least 0.75 of the load-bearing width of the sling;
It is prohibited to use slings to move loads when removal from under them involves friction of slings sandwiched between the load and other surfaces, as well as to pull slings out from under the load;
slings must be protected from the influence of harmful factors of the transported cargo (for example: acid, alkali, solvent, molten substances);
It is prohibited to move products heated above 100°C;
it is prohibited to place the places where the tapes are stitched directly on the load-handling device;
when working with slings, jerks and impacts of loads should be avoided;
Forced drying of slings by any means is not allowed.
3.8 To eliminate possible sparking from the slings accumulating from friction against part of the load, the following methods are used:
treatment with the drug “Antistatic” (frequency of treatment according to the instructions for use of the drug);
braiding metal threads or tapes (at least two) with a cross-section of at least 0.5 mm2 each;
enclosing the tape in a cover made of cotton fabric.
4. REJECTION RULES
4.1 According to the requirements of the Safety Rules, slingers must inspect slings before using them for lifting and moving loads with lifting machines.
4.2 Engineering and technical workers responsible for maintaining lifting machines in good condition and persons responsible for the safe performance of work with cranes and other lifting machines must inspect slings (except for rarely used ones) - every 10 days, and rarely used removable lifting devices - before releasing them to work.
4.3 When inspecting slings, it is necessary to pay attention to the condition of the straps, hooks, hangers, locking devices, carabiner clips and places of their fastenings.
4.4 Slings with:
knots on the load-bearing belts of slings;
transverse cuts or tears in the tape;
longitudinal cuts or tears of the tape, the total length of which exceeds 10% of the total length of the sling tape or single tears with a length of more than 50 mm;
local delamination of the sling tapes, except for places where the edges of the tapes are sealed for a total length of more than 0.5 m on one outer seam or two or more internal seams (when three or more seam lines are torn);
local delamination of sling tapes in the place where the edges of the tape are sealed for a length of more than 0.2 m on one of the outer or two or more internal seams (when three or more seam lines are torn), as well as peeling of the edge of the tape or stitching of tapes at a loop for a length of more than 10 % of the length of the sealing (stitching) of the ends of the tapes;
surface breaks of belt threads with a total length of more than 10% of the belt width, caused by mechanical action (friction) against the sharp edges of the load;
damage to belts from exposure to chemicals (acid, alkali, solvents, petroleum products, etc.) with a total length of more than 10% of the width and length of the sling or individual damage of more than 10% of the width and length of more than 50 mm;
bulging of threads from a sling tape with a diameter of more than 10% of the tape width, including through holes with a diameter of more than 10% of the tape width from the impact of sharp objects;
burnt through through holes on the sling tape from the effects of splashes of molten metal with a diameter of more than 10% of the width of the tape or more than three holes with a distance between them of less than 10% of the width of the tape, regardless of the diameter of the holes;
belt contamination (petroleum products, resins, paints, cement, soil, etc.) more than 50% of the sling length;
delamination of tape threads.
4.5 Repairing the sling is prohibited
4.6 Rejection of rings, loops, staples, pendants, clips, carbines, links and others metal elements sling
Not allowed:
wear of the surface of elements or local dents leading to a decrease in cross-sectional area by 10% or more;
the presence of residual deformations leading to a change in the original size of the element by more than 3%;
damage to threaded connections and other fasteners.
4.6. The results of inspection of textile tape slings must be recorded in a special journal in accordance with the Safety Rules.
5. TRANSPORTATION AND STORAGE
5.1 Slings should be stored in a well-ventilated room at a temperature from -30°C to +30°C with a relative humidity of no more than 80%, placing them on stands, away from heat sources, no closer than 0.2 m, avoiding contact with chemicals, fire, corrosive surfaces, protecting from direct sunlight and other sources ultraviolet radiation. Before placing the lanyard for storage, it should be inspected for any damage that may have occurred during use. Storing damaged slings is not recommended.
