The 12 slings the company chose were made by Gleistein Ropes using Dyneema® SK78. They are strong yet flexible and allow for a compact lifting setup. In total, they weigh between 560kg and 1,030kg each, and have a breaking load of 4,500t (SWL: 900t) each. Together with the lifting gear setup, combined total weight comes to approximately 8.5t. This is around 57t less than a comparable conventional steel rope solution, which effectively increases the maximum lifting payload by the same margin.
Ability to lift more saves client time and money
The benefits of going cutting-edge became clear in early 2017 when the crane/sling combination set a new world lifting record. At more than 3,000t, it was the heaviest commercial load ever to be lifted by a land-based mobile crane.
But the record wasn’t the only benefit. The record-breaking lift was part of a four-month project to lift 40 separate modules weighing a total of over 36,000t for an FPSO vessel integration project in Brazil. Crucially, ALE’s ability to install complete modules on the FPSO meant there was no need to move the ship’s hull for final construction. This not only saved ALE’s client money, but also a significant amount of time in the overall construction schedule.
And none of it would have been possible without Gleistein Ropes’ dedication and their slings made with Dyneema® SK78.
