Q: What tools are used to design a sling made with Dyneema® SK78?
A: Slings are the vital link between a high-value crane and load, so they need to be fit for their intended purpose. With DSM’s Performance Model, the fatigue lifetime of a sling made with Dyneema® SK78 can be determined based on both static and dynamic loading conditions performed in any climate. These tools also help in reducing project costs.
Q: How do slings made with Dyneema® SK78 compare to generic HMPE alternatives on tension fatigue?
A: DSM has engineered Dyneema® SK78 fiber in such way that it offers at least twice the fatigue performance of generic HMPE fibers. At fiber and at sling level. The rope temperature and fatigue models developed by DSM allow for accurate prediction of rope core temperatures in static and dynamic conditions, as well as fatigue life.
Q: What temperature conditions can Dyneema® SK78 withstand?
A: Dyneema® SK78 fiber is scientifically proven to perform very well from -40°C to 70°C, with short-term exposure up to 100°C not causing any serious loss in performance. This is well within the operating temperatures of heavy lifting slings. Dyneema® fiber can even withstand cryogenic temperatures.
