Why choose Dynamica Helicopter lines?

If you need helicopter lines that are safer, lighter and strong alternative to steel wire ropes.

Dynamica Helicopter lines are manufactured with continuous endless lengths and a core that makes them compact and dimensionally stable. They are impregnated and heat-stretched giving them excellent spooling abilities on any type of winch.

By changing from steel to Dynamica Helicopter lines, you gain:

  • Lighter handling without compromising on strength

  • Safer handling, minimised danger of injuries

  • Even lifts due to low elasticity

  • Comfortable to handle due to the stiff construction

  • A compact and dimensionally stable rope

  • A custom-made rope with excellent spooling abilities

What is the breaking strength & weight of Dynamica Helicopter lines?

Dynamica Helicopter lines are manufactured with HMPE/Dyneema® making them as strong as steel while being up to 10 times lighter.

Our Helicopter lines are most often produced with HMPE/Dyneema® SK78 fibres. For operations that require extraordinary long lengths or where there is limited space on the winch, they are made with SK99.

What is the elongation of Dynamica Helicopter lines?

Dynamica Helicopter lines have similar elongation pattern as steel wire ropes because of the elongation of only 3-4 %.

Eventhough we heat-stretch the lines, during the first operations you will experience constructional elongation. After some operations, the line will become length stable.

The stiff construction and low elasticity makes the Dynamica Helicopter lines comfortable to handle and secures an even lift.

In case of break, the Dynamica Helicopter lines' low mass and elongation results in the energy being distributed along the entire length in a linear fashion with a relatively low recoil. Whereas, steel wire is known for lashing out endangering people and equipment.

Is Dynamica Helicopter lines rotation free?

Dynamica Helicopter lines have a 12 strand braided construction which is 100 % rotation free.

However, it is important to avoid rotating the rope during spooling; the rotated rope will lose its strength which creates risk of failure.

Do & don't

To take full advantage of your rope, do not use it over rusty surfaces and sharp edges as this can lead to cuts, abrasion and splice damages.

Cleaning the Dynamica Gliding rope prolongs its service life. If mud and sand penetrate the rope, it will with time start to act as sandpaper. Remove dirt by hosing down your rope with water at law pressure.

When spooling the helicopter line on the winch, be careful that the rope does not cut into the lower layers.

When the rope is not in use, store it in the shadow.

How to cover & protect Dynamica Helicopter lines?

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

Dynamica Helicopter lines are protected by a special DSC (double shield coating) and heat-stretching proces from tension, dirt, mud and rust. The impregnation locks the fibres and prevents dirt from penetrating the rope.

To attain even greater abrasion resistance, we deliver Dynamica Helicopter lines with either a braided polyester or Dynamica PRO cover.

We will assist you in choosing the right cover.

What to look for while inspecting Dynamica Helicopter lines?

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

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

  • Splice damage

  • Construction damage

  • Cover damage

  • Signs of overheating

  • Abrasion

  • Inconsistent diameter

  • Damage caused by inconsistent spooling on drum
