In 2019, we launched the Konecranes S-series hoist with synthetic rope instead of traditional steel wire rope. Since then we've sold hundreds of S-series hoists to customers around the world who are thrilled with the cleanliness and durability. And we just recently introduced a low headroom version of the popular S-series hoist and the revolutionary Konecranes X-series crane.
We’re the first company to produce overhead cranes with synthetic rope as a default and we’ve put it through extensive lifetime tests to ensure safety, strength and durability. The synthetic rope we use in our hoists is made with Dyneema®—one of the world’s strongest fibers—which has been used for more than 30 years in demanding rigging applications such as lifting slings, mooring and towing large sea vessels. Lives also depend on it during search and rescue operations and mountain climbing. So keep reading to learn all about synthetic rope and how it compares to steel rope.
The synthetic rope has a 12-strand non-rotating structure that is hollow inside. The stable structure of the rope removes or substantially reduces the risk of certain rope defects that steel ropes are prone to like birdcaging, waviness, core protrusion and kinks.
And while steel rope has multiple variations such as rotation resistant, heavy duty, left and right hand, galvanized and stainless steel, or for different lubrication—there is only one variation of the synthetic rope to fit the same applications.
The lightweight rope is easy to handle and doesn't fray or produce sharp barbs, minimizing the risk of cuts on the hands of anyone handling the rope. There's also no need to worry about broken steel wires contaminating the area or load.
The strands, yarns and fibers of the synthetic rope slide easily against each other so there’s no need for additional lubrication and the hoist drum is pre-coated to prevent corrosion.
You'll save time during maintenance as there's no need to wash away lubricant for inspection or add lubricant. There's also no need to worry about lubricant from the rope harming the process below the crane.
It may just be lubricant - but the small details add up.
Synthetic rope sits evenly against the reeving components, minimizing surface pressure and leaving virtually no imprints that can potentially decrease the useful lifetime of the reeving components. The rope also slides easily against the guiding surfaces of the reeving components helping increase their useful lifetime. Easy sliding also means less heat loss and improved mechanical efficiency of the whole reeving system.
Another one of those little details - dust. Unlike steel rope, synthetic rope doesn't attract and collect dust that can cause accelerated wear of rope and reeving components.
