Groundbreaking & Innovative

dynemaa + logoLift-Tex® Industrie B.V. has a scoop! As the first manufacturer of synthetic lifting materials worldwide, Lift-Tex® succeeded  in producing a synthetic round sling with a MBL of 2500T. A roundsling with such a strenght (lifting capacity) breaks a record in the international lifting industry. The sling is tested in an official testing location of DNV/GL in Norway, on one of the biggest testing benches in Europe. For more information, read our Press release.

For Heavy Lift projects in the wind energy, oil, gas and on-and offshore industry, this is a breakthrough concerning the transportation, (re)placement, installation or disassembling of mega modules by using round slings instead of steel cables or ropes. 


The EXTREEMA® round sling can save offshore specialized companies a lot of costs thanks to the lightweight slings. EXTREEMA® round slings are very flexible and can be produced in various models, in contrary to steelcable slings, lifting ropes and chains. The round slings are therefore very user friendly. Waiting times are reduced to a minimum thanks to the short and flexible delivery times. 

Unlike braided fibre ropes, the construction of an Extreema® round sling is based on parallel laid fiber technology that make up the core. The core of an Extreema® round sling is always made of 100% high performance fibers such as Dyneema® , the world’s strongest fiber™, or general HMPE. This makes the slings up to 15 times stronger than steel on a weight for weight basis and a weight reduction up to 80% compared to wirerope. Parallel laid fibre technology Extreema® round slings have proven to be significantly stronger (between 30-50% higher MBL’s!) when break loaded on Ramshorn DIN shaped hooks compared to braided fibre ropes.

Extreema® round slings with Dyneema® core yarn material can be supplied with a EU-origin certificate of the core material and DNV Approval of manufacture certificate by DSM Dyneema®. Extreema® round slings with general HMPE core yarn material can only be accompanied with a Certificate of Conformity acc. to the Machinery Directive 2006/42/EC. Compared to high tenacity polyester, Extreema® slings are up to 3 times lighter with a much smaller core diameter.

Polyester Core

Polyester round slings take up water and will sink due to their heavy weight. Furthermore, wet polyester round slings are difficult to dry before storage and with temperatures below 0˚ degrees Celcius, the water in the core yarn material will freeze and become massive ice. Once broken, the ice inside the cover (invisible to the naked eye!), become a cutting agent (!) which will damage and weaken the sling in it’s lifting capacity and might become an unsafe lifting tool. This will be limited with Dyneema® core materials.

The growing awareness in the Heavy Lift industry shows an increasing demand for EXTREEMA® lightweight slings that are flexible, safe and easy to work with. Extreema® lightweight soft slings reduce environmental pollution and the choice for the right Extreema® construction (Core, Cover & protections) will significantly drop the total cost of ownership and have proven to be a cost saving investment for challenging Heavy Lift projects on –and offshore in many industries.
