Dyneema winch ropeDynamica DSC Winch Lines are custom-made and can be manufactured in diameters from 2 to 48 mm in continuous endless lengths. Dynamica DSC Winch Line is the ultimate synthetic replacement of heavy and dangerous steel wire. Dyneema® Winch Lines are designed with a core, which makes the rope compact and dimensionally stable. The highly abrasion resistant polyester or Dyneema® jacket ensures effective protection against abrasion. The state-of-the-art impregnation and stretch system ensure excellent spooling on any type of winch.

Winch Lines in operation are subject to tension and in some cases dirt, mud and rust can penetrate the rope. In order to avoid that, Dynamica Ropes developed a DSC coating system, in which the entire rope is undergoing a heat setting process in several steps.

Dynamica Ropes delivers Winch Lines for all kinds of lifting and pulling operations both Offshore and Onshore:

  • Deep Sea Operations
  • Deep Sea Lifting
  • Cable Pulling
  • Offshore Oil & Gas operations
  • Seismic
  • Research & seabed sampling
  • Trawl Warps Winches, Gilson Lines
  • Traction Winches
  • 4×4 WD winches
  • Armoured Vehicles Winches
  • ROV Winch Lines
  • Marine Winch Lines: Mooring Lines and Towing Lines
  • Hoist winch in wind turbines
  • Winch Lines for Gliders and Paragliders

Cable pulling with DYNAMICA SK99, the cost saving and easy-to-handle solution

Strong, lightweight and easy-to-handle DYNAMICA SK99 used for cable pulling in the Middle Eastern highland. It was not only about getting the job done, but also saving money by cutting down man-hours and operation time. 

The operation was as follows: the strong and light rope had to be selected by Operator and pulled by helicopter to connect high voltage transmission lines to electricity poles. However, the operation was not that simple, as it included a demanding location and mechanical limitations, thus regular feeder lines were not an option.

The customer contacted John Baburaj at Dynamica Ropes, who suggested to use the DYNAMICA SK99 as feeder lines. SK99 is the strongest grade of Dyneema® on the market, and known for its ability to maintain the highest breaking strength and having the smallest diameter at the same time. The unique heat setting and heat stretching system for SK99 ropes, used at Dynamica Ropes, contributes to the “slim rope” which gain additional strength due to the alinement of fibers in the dual process of heating and stretching.

This meant that a DYNAMICA SK99 feeder line would conform to the mechanical limitations of the designed pulling operation, but also have enough strength to act as feeder lines.

»It is not only the fact that DYNAMICA SK99 is the strongest, but it is also lightweight,« says John. »This has resulted in the customer saving money because of the deducted man-hours and operation time.«

DYNAMICA SK99 can be used in a wide range of industries for countless applications, especially when extreme strength and small diameter are required. SK99 is also a good option for winching application where the space on the winch is limited.

DYNAMICA DSC Winch Lines for J-Tube cable pulling

Dynamica Ropes provided MacArtney with high-technology fiber ropes made with Dyneema® for 2 electrical winches, which are going to bring inter-array cables and export cables from the seabed onto the substation deck in Borkum Riffgrund 2 Offshore Windfarm.

The advanced & operation optimized winches are fitted with Dynamica’s Winch Lines called DYNAMICA SUPERIOR DSC.

These ropes were designed particularly to fit for the operation at 450 MW Borkum Riffgrund, which will consist of 56 MHI Vestas 8 MW turbines. The 200 kN winch is stationary for pulling export cables; the 150 kN winch rotates 360 degrees which reduces the costs of reversible units & sheave blocks and enables a straight pull into all J-tubes.

DYNAMICA SUPERIOR DSC is provided with a tailor-made heavy-duty jacket, which ensures extremely high abrasion resistance and protects the Winch Line when handling deep-water operations. The hard multilayer fiber core ensures compact and dimensionally stable Winch Lines, which easily are applied and handled on the electrical cable pulling winches.

Dynamica Ropes has developed a DSC coating system, which prevents mud and dirt to penetrate the rope during installation. The treatment is closing the fibers and the heat set process assures the impregnation to penetrate the rope. DYNAMICA DSC Winch Lines are the ultimate synthetic replacement of the heavy, greasy and dangerous steel wire. The project is expected to be fully commissioned in 2019.

Glider launch with static Dyneema® ropes/Dyneema® lines

We believe that static ropes or lines made with Dyneema® within a few years will replace steel wires in the glider business. Until now, steel wires have been used for launch, but there is a range of advantages using static ropes/lines for gliding instead. Based on several test flights, it is obvious that it is easier and more economical to use Dyneema® ropes / Dyneema® lines for gliding, compared with steel wire.

Midtjylland Gliding Club has during the past years used 5 mm DYNAMICA gliding ropes made with Dyneema® for glider launch and is very satisfied. Thomas Nielsen, gliding enthusiast, tells that the static ropes have been a proven success, and continues: “DYNAMICA gliding ropes are very comfortable during take-off because of the stiff construction. To compare, steel wire is much more elastic and contains after a short time a lot of gatherings, which make the take-off uneven.

Helicopter winch lines made with Dyneema®

Pacific Helicopters is using DYNAMICA ropes and has done it for the last 10 years. They use DYNAMICA ropes (helicopter long lines) to transport and positioning loads with helicopters since they have the most stable length due to an advanced heat setting system used during the production process.

Chief Pilot, Scott Laing says:

“It has been very successful. We use 12 mm longlines up to 250 feet and have a 5-year retirement life on those lines. Our maximum load is around 1200 kg, so the DYNAMICA lines secure a very high safety factor.”

Winch lines for 4×4 – the synthetic replacement of steel wire

DYNAMICA ropes are widely used as Recovery Ropes for different kinds of situations and in different weather conditions. Dynamica Recovery Ropes are not affected by oil or water and are just as strong whether used in dry, cold or wet conditions.
