SafeLift Slings

Case Lindø

Time is money in heavy lift operations

- changing to Dynamica rope slings

Determining the speed of your lifting operations? The responsible lift engineer for Denmark's largest gantry crane had one goal; to save time and money by upgrading the lifting gear with focus on size and efficiency.

The gantry crane, with a capacity of 1.200 t, is used several times a month both to gather the jackets and move them around for storage or shipping. The process involves lifting 3D structures, which have a height of 55 m and weigh approximately 500 t a piece, where rigging needs to be done at a height of 50-60 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 Port of Odense used polyester slings, with a diameter of 101 mm and weight of 186 kg, for this type of lifting until 2016. They replaced the polyester slings with 40 mm Dynamica SafeLift Slings manufactured with HMPE/Dyneema®. These slings only weigh 45 kg a piece - a weight reduction of no less than 141 kg compared with a polyester sling.

"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.“

Peter Blazejewicz, Transport Engineering Manager at LINDØ Port of Odense

Time is saved primarily because the switch to the lightweight 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.

"We naturally examine both the theoretical properties and actual physical condition of new lifting gear before we use it – and are very impressed by the properties offered by Dynamica Ropes’ lifting slings. After a meticulous deliberation of the lifting task at hand with Dynamica Ropes' technical consultant and the R&D team, we decided to buy SafeLift Slings and this has turned out to be a great decision.”

“Two persons are now capable of handling the lifting sling […] and next to that the sling enabled them to reach all 4 lifting points in one go, without having to move the truck around”
