Lindø15 300Slings for wind projects are used for different purposes. DYNAMICA SafeLift slings are mainly used for:

• Lifting of jackets, foundations and TP’s
• Upending of jackets
• Lifting and upending of wind turbine towers
• Lifting of nacelles
• Positioning of the blades during installations
• Taglines for winches
• Sea-fastening during transport
• Cable pulling
• Lifting of spare parts inside the towers

Dynamica Ropes has a constant focus on quality and innovation and we continuously improve our products.

Lindø Industrial Park saves time and manpower chancing to Dyneema® ropes slings.

Lindø Industrial Park saves time and manpower by replacing heavy polyester slings with lightweight Dynamica SafeLift slings manufactured with Dyneema®. This case it is about lifting a so-called 3D structure, but it could just as well be an operation regarding lifting a windmill tower.  

The industrial park on Funen has a great experience with the handling and shipping of large components for the offshore and heavy industry. The industrial zone in Odense is, among other things, a collection point and a storage depot for jackets (offshore wind turbine foundations). Jackets are 63 m tall steel structures with a weight of up to 665 t per piece. This figure corresponds to the weight of 27 fully loaded lorries!

A gantry crane with a capacity of 1,000 t is used several times, both to gather the jackets and then to move them around for storage or shipping. The process involves lifting of so-called 3D structures, which have a height of 55 m and a weight of approx. 500 t per piece, where rigging needs to be done at a height of some 50 or 60 m. A lifting sling is lowered down along the foot of a jacket, pulled underneath two stiffs, and then guided back up to the beam. Lindø Industrial Park has used polyester slings for this type of lifting until very recently. A standard polyester sling in this case had a diameter of 101 mm with a weight of 186 kg. However, polyester has now been replaced with hi-tech Dyneema® ropes slings manufactured by Dynamica Ropes. More specifically, these 40 mm Dynamica SafeLift slings only weigh 45 kg per piece. A weight reduction of not less than 140 kg comparing with a polyester sling.


Peter Blazejewicz, Transport Engineering Manager at Lindø Industrial Park, says:

„The weight reduction means that we save at least 45 minutes on each lifting operation. Since each lift involves a 1,000 t portal crane, a 103 m truck-mounted lift and normally seven employees, the time savings are undoubtedly substantial.“

Time is saved primarily because the switch to the light Dynamica SafeLift slings has made it possible to reach all four rigging points without moving the gigantic 103 m truck-mounted lift around. As the polyester slings were substantially heavier, the truck-mounted lift’s capacity could not reach the four rigging points from one place, and the lift therefore had to be moved at least once, with corresponding rigging and de-rigging.

Peter Blazejewicz continues:

We naturally examine both the theoretical properties and actual physical condition of new lifting gear before we use it – and we were very impressed by the properties offered by Dynamica Ropes’ lifting slings. After a meticulous deliberation of the lifting task at hand with Enes Hadziefendic, Technical Consultant at Dynamica Ropes, we decided to buy SafeLift slings, and this has turned out to be a great decision.”


Jørgen Sørensen, CEO of Dynamica Ropes, says that the strong 12 strand braided rope is particularly interesting for the offshore industry, which often places major requirements on the weight and size of the lifting gear. Enes Hadziefendic adds: “In the case of Lindø Industrial Park, two persons must be capable of handling the lifting sling at a height of 50 to 60 meters, and the truck-mounted lift must be able to reach all four rigging points without being moved around.” This places immense requirements on the weight of the lifting equipment and simultaneously gives a priority to a small diameter because of the somewhat special rigging. ”

The SafeLift sling mentioned in this case is made of 12 strand braided rope, which is made with Dyneema® fiber, the strongest man-made fiber as of this day. SafeLift slings are supplied with a thick woven cover with Double Shield Coating at both eyes and in the middle of the sling to ensure protection against wear. The woven covers along with proper handling during lifting operation guarantees a long service life for the lifting gear.

At last, yet also important gain made with the switch to Dynamica SafeLift slings is better working conditions for the riggers at Lindø Industrial Park. Peter Blazejewicz says:

“Rigging with the polyester slings was physically demanding for the riggers. The switch to SafeLift slings has made this very heavy lifting easier for them. ”


DYNAMICA Lashings made with Dyneema® are ideal for onshore and offshore transport of for example windmill blades and parts of wind turbines. DYNAMICA Lashings have limited backlash energy in case of break, which is an important safety factor. Furthermore, the lashings are soft and very hand friendly to deal with. The soft ropes also secure that the surface of the goods, which are secured for storage or transport, is not scratched. Compared with chains and hard strops DYNAMICA Lashings are both safer and easier to handle.
