35×K7 – compacted, low rotation wire rope for the heaviest loads
For safely lifting extremely heavy loads, the 35×K7 wire rope is the best choice. A special process compacts the strands, making the rope highly stable and resistant to wear. One major advantage is that: The rope is rotation-free, so the load will not twist dangerously during lifting. Whether you’re working on large construction sites, in the offshore sector, or in heavy machinery manufacturing, you can rely on the 35×K7’s maximum strength and highest level of safety.
Designation: 35×K7 describes a wire rope with 35 strands, each consisting of 7 wires and additionally compacted (K = compacted strands).
Properties: The 35×K7 construction offers exceptional torsional stability and a highly durable surface. Compacted wires provide increased tensile strength as well as improved resistance to abrasion and crushing.
Application: For demanding applications involving multi-strand lay, pulley blocks, and heavy loads. For example, for cranes on oil platforms or tower cranes, where low-twist and rotation-resistant ropes are required.
Material: We offer these ropes in a galvanized finish. This makes them ideally suited for outdoor use as well as in demanding industrial environments.
Versions at Hamburger Drahtseilerei: We offer 35×K7 ropes in various diameters by the meter, with optional custom end fittings and coating.

Applications of the 35×K7 construction
Maximum performance thanks to a compacted strand structure
Compressing (compacting) the strands gives the rope a particularly smooth surface. This offers a major advantage: the rope glides more easily over pulleys and drums, which means it wears down much more slowly. At the same time, it is extremely resistant to external pressure. The result is a wire rope that lasts a very long time and remains safe even under the most demanding operating conditions.
When is the non-compacted version better?
If you do not need to handle extremely heavy loads, the standard 35×7 version may be the right choice. It also does not rotate during lifting, but is slightly more flexible. The “standard version” is particularly well-suited for normal lifting tasks where the rope is not subjected to quite as much stress. We would be happy to advise you on which version is best suited for your application.
