Why choose Dynamica SK75?

If your operation requires a strong and light rope for a standard application.

Dynamica SK75 is a part of our standard range of ropes produced with HMPE/Dyneema®. It is a versatile rope used in many different industries and applications.

If your operation requires a rope with lower creep, choose Dynamica SK78.

If your operation requires a rope with higher strength, choose Dynamica SK99. 

What is the breaking strength & weight of Dynamica SK75?

Dynamica SK75 ropes are just as strong as steel wire ropes while being up to 10 times lighter meaning a top of line weight to strength ratio, which ensures:

  • Easier rigging

  • Decrease in handling speed

  • Less resources required

  • Fewer riggers and less equipment required

  • Overall cost-saving

What is the elongation of Dynamica SK75 ropes?

SK75 ropes have low elongation similar to steel while being a safer alternative.

In case of rupture, SK75 ropes’ low mass and elongation results in the energy being distributed along the rope’s entire length in a linear way with a relatively low recoil. Whereas, steel wire is known for lashing out endangering riggers and equipment.

Is Dynamica SK75 rotation free?

Dynamica SK75 has a torque-neutral construction which means that “snaking”, bird caging and kinking is not an issue, which is a common problem with steel wire ropes.

Do & don’t

To take full advantage of your Dynamica SK75 rope, do not use it over rusty surfaces and sharp edges as this can lead to cuts, abrasion abuse and splice damages. To ensure long service life while protecting the riggers, ensure all surfaces are in proper condition.

How to cover & protect the SK75 rope?

Want longer service life? Protect your rope with a cover!

With a cover your Dynamica SK75 ropes become even more abrasion resistant. We always recommend using a cover (braided or woven) in the eyes and other bearing points. For some operations, we recommend a cover on rope’s entire length.

The choice of cover depends on the specific application, we will assist you in choosing the right cover. Below you can read more about covers that if most often used with SK75 ropes.

What to look for while inspecting Dynamica SK75?

Regular inspections ensure a long service life and keep the total cost of ownership down.

Inspect your SK75 rope before every operation looking for the following signs:

  • Rope construction damage

  • Cover damage

  • Abrasion

  • Inconsistent diameter
