The TEUFELBERGER steel-wire rope division is specialised in the development, production and marketing of high-performance special steel-wire ropes. Two production facilities and 185 motivated associates generate six million metres of steel-wire ropes each year, dedicated to OEMs, dealers and end-users for all applications like ropeways, cranes and forestry.
Demanding the highest performance and permanent use in extreme environmental conditions is characteristic for offshore cranes and riser tensioner applications. High device disposability is very important far away from the coast, while safety and reliability are crucial factors for both crane plants and the steel-wire ropes in use. TEUFELBERGER offshore ropes serve to demonstrate these factors daily on numerous platforms all over the world.
We manufacture two types of non-rotating rope. Our EVOLUTION TK 16 is an ordinary lay or langs lay rope, suitable as hoist rope in multi or single-layer winding. We also offer EVOLUTION TK 18, which is an ordinary lay or langs lay rope with a big diameter, suitable as hoist rope in multi or single-layer winding.
Non-rotating resistant ropes
Our range of non-rotating resistant ropes includes the QS 816 VG eight-strand langs lay rope, which is recommended as boom hoist rope exclusively in multi-layer winding; the QS 816 V eight-strand ordinary lay rope, which is especially suitable as boom hoist rope in single-layer winding; the QS 814 VG eight-strand langs lay rope specially developed as riser tensioner rope; and the EVOLUTION Q 8 eight-strand ordinary lay rope that is especially suitable for van carriers, RTGs, ship-to-shore cranes and container bridges.
Steel-wire ropes for offshore applications
TEUFELBERGER special steel-wire ropes for offshore cranes distinguish themselves by offering the highest reliability under the most challenging conditions. In addition, extremely high breaking forces – provided by SUPERFILL® compaction technology – ensure the highest levels of safety in daily operations.
Our special ropes featuring PLASTFILL technology have a plasticised rope core and galvanised wires, which provide the highest resistance against corrosion in the inner rope. Additionally, a special grease ensures optimal lubrication of all components.
Our worldwide network of suppliers with decentralised storage ensures that our customers have a peak supply of spare parts.
All of these factors combined translate into a significant increase in your rope's service life, and reduction of standstill periods and maintenance costs. This means that total costs, when compared with the device's service life, are considerably reduced.
Research and development of steel-wire ropes
TEUFELBERGER's R&D department provides ongoing product improvement in terms of safety, reliability and service life. TEUFELBERGER has state-of-the-art testing facilities including our rope technology centre at our site in Wels, Austria.
The TEUFELBERGER engineering team is available at short notice to solve problems and find solutions for customers around the world. These engineers are specially trained for offshore applications, and can use their expertise to resolve any problems that may occur.
Compaction technology for steel-wire ropes
Our SUPERFILL compaction method has been developed in close cooperation with universities and independent research institutions. Each rope strand is compacted in a specific procedure with the aim of significantly improving the rope's properties. This results in:
- Up to 30% more breaking forces than non-compacted ropes
- Prolonged service life due to reduced nominal stress
- Use of smaller rope diameters of the same breaking load (important for new crane constructions)
- Smooth rope surface results in reduced abrasion on rope, sheaves and drums
- A continuous, constant wire rope diameter tolerance for long lengths
Steel-wire ropes with lubricated steel core
With our PLASTFILL technology the lubricated steel core of our steel-wire ropes is enclosed in a tight synthetic coat. This provides long service life through permanent lubrication, as well as resistance against pressing and lateral pressure. It also results in higher breaking forces through reduced friction in the rope, and resistance against corrosion.
The strands are embedded in the synthetic coat during the stranding process. The advantages of this are:
- Exact strand position with consistent interstices for reduced internal abrasion
- Equal load shares at all components due to optimised construction
