The construction of an Extreema® round sling is based on parallel laid strands that make up the core.
This core is always made of 100% high performance fibers HMPE such as Dyneema.
This makes the slings 15 times stronger than steel, compared to polyester,
Extreema slings are 3 times lighter with a much smaller diameter.
Dyneema is a High Modulus PolyEthylene Fiber (HMPE or UHMWPE) which offers maximum strength combined with minimum weight.
For this reason Dyneema, manufactured by DSM in the Netherlands, is known as “the world’s strongest fiber”™.
| Extremely low in weight | : 8 to 10 times lighter than quality steel |
| : Up to 2,5 times lighter than polyester roundslings | |
| Small diameter | : 2,5 times smaller than polyester round slings |
| Maximum capacity | : 4.000 metric ton MBL (straight pull) |
| Maximum length | : 80 metres |
| Specific gravity (g/cm³) | : 0.97 (floats on water) |
| Elongation in use | : ∼ 0,5% elongation at WLL |
| : Similar to wire rope slings | |
| Weight reduction in % | : Up to 80% compared to wire rope slings |
| : Up to 60% compared to polyester round (and rope) slings | |
| Effect on chemical exposure* | : Excellent on (sea) water, moisture |
| : Good resistant against acids an alkali | |

Using Dyneema fibers to build the core of the sling gives multiple advantages:
– The slings are easy to handle because of its light weight and flexible form
– Less than 1% stretch at W.L.L., therefor suitable for calculated lifts
– Small diameter, 2,5 times smaller than regular polyester round slings
– D:d = 1:1 for round slings up to 200T, above this D:d = 1:1,5
– Resistant against chemicals, but do always inform us if chemicals are involved
– Does not absorb water, Extreema® slings float on water
– Extreema round slings do not suffer from fatigue like steel wire slings (ropes)
– Less back & hand injuries, no sharp edges
– Extremely ergonomic compared to synthetic or steel ropes
– Extremely high life cycle compared to polyester slings
– No rust or corrosion like on steel wire ropes
We offer four different options to cover the round sling.
– 100% Dyneema (White or black)
– 100% CORDURA (Black)
– Blend of Dyneema and CORDURA (Black and white)
– 100% Polyester
As a result of its high resistance against cuts, abrasions and puncture Dyneema® is already used in many industries, such as military and extreme sports.
Also the super-durable fiber CORDURA is a primary ingredient in many of the world’s leading highperformance gear.
Known for its resistance to abrasions, tears and scuffs.
Each version of EXTREEMA has its own characteristics.
The CORDURA variations will be a perfect fit for lifting objects with higher temperatures, while still maintaining extremely cut and puncture resistant.
However, the 100% Dyneema jacket will still be a perfect fit for repetitive loadouts of payloads with extremely sharp edges.
| Dyneema® – Extremely durable – Stretchable – No damage to payload – Proven track-record in many industries/applications – Chemical resistant – Extremely resistant to cuts, abrasion and puncture | CORDURA® – Extremely durable – Stretchable – No damage to payload – Resistant against higher temperatures – Resistant to frictions and abrasion |
The D:d is the ratio of the diameter (D) around the object which the sling is bent divided by the overall diameter (d) of the sling being used.
Rope and wire rope generally have a D:d of 1:4 and polyester slings have a D:d of 1:2,5.
Extreema slings enable you to work with a D:d of 1:1 (>200T D:d = 1:1,5).
Making it possible to use regular shackles instead wide body shackles.
Extreema protection come in 100% Dyneema, 100% CORDURA or a blend.
The protection sleeves are equipped with Velcro, or come as a (not dismountable) tight sleeve.
The main application for these products is the protection lifting equipment and the object that will be lifted.
It can be mounted on synthetic round slings, webbing slings, steel wire rope & chains, lashings and synthetic ropes.
– Significantly longer life-time of round slings and webbing slings
– Easy to put on, easy to take of equipped with Velcro
According to the EN-1492 regulations for safe use of round slings the sling should be protected on the
anchoring point (shackles, pins, etc.) as well as the lifting appliance (crane hook).
According EN 1492-1:2000+A1:2008 C.3.6 Slings should be protected from edges, friction and abrasion,
whether from the load or the lifting appliance.
Where protection against damage from edges and/or abrasion is supplied as part of the sling,
this should be correctly positioned.
It may be necessary to supplement this with additional protection.
According EN 1492-2:2000+A1:2008 D.3.7 Slings should be protected from edges, friction and abrasion,
whether from the load or the lifting appliance.
Where reinforcements and protection against damage from edges and/or abrasion is supplied as part of the sling,
this should be correctly positioned. It may be necessary to supplement this with additional protection.
For repetitive loadouts with sharp edges around the object the EP-XL or EP-XXL are the perfect solution to protect your sling.
The EP-XL has a single thickness of 3mm (6 mm double) and the even more cut resistant EP-XXL is 6 mm thick in single use (12 mm double).
– Made from 100% Dyneema
– Highest abrasion resistance of any fiber
– Excellent dynamic toughness and very low elongation
– Excellent flex fatigue resistance
– Superior cut, puncture and tear resistance
– Significantly longer life-time of round slings and webbing slings
The Extreema Corner Protector is made from 100% Dyneema.
Because of the two velcro straps, the Corner Protector is extremely easy to mount on the sling.
The flexible Dyneema pad makes it possible to use the sling in any situation, with no fixed angle.
