Make the right choice
Move loads safely and efficiently, both vertically and horizontally. Get the most out of your installation assured business continuity. This requires the right (application of) steel wire rope. You can read all about it in this file.
Steel wire rope is at the heart of many installations. With the right construction, application, implementation and installation, you ensure that employees can work safely. It can also extend the life span of the steel wire rope, prevent downtime of the machinery, increase productivity and reduce the total cost of ownership.
Steel wire rope has a wide variety of possible applications. How do you make the right choice? There is a lot involved. From diameter, lay method, construction and type of material to the application, installation and use.

Steel wire rope assortment
Steel wire ropes are one of the most important product categories at Mennens. Steel wire ropes are necessary parts for many of your installations. A lot depends on the applied steel wire's construction and quality, because it determines whether your installation will function right or not. Not all applications demand the same steel wire quality.
Q&A Webinar Steel Wire Rope, April 22nd, 2021
To be certain you will not have extreme wear of grooves in sheaves – and/or negativ imprints. Please ask for hardness of surface of 320HB.
To be certain you will not have extreme wear of grooves in sheaves/drums – and/or negativ imprints. Please ask for hardness of surface of 320HB – if you use 2160 N/mm² ropes – 350 HB.
Ropes should never come off from reel or bobine in wavy form. This is wrong winding and should always be straight laying on the floor.
For a certain application with a certain rope installed or to be installed you can use the actual breaking load. For developing new installations you have to focus on minimum breaking load.
No, if you re-lubicate your ropes they wil automatically grease your grooves of sheaves and drums, but it depends also on your application, and on the environment the boat is located. For hoisting ropes in overhead cranes 1 or 2 times in a lifetime of the rope will do the job. Please use special steel wire rope lubricants (I prefer oil no grease but it depends on the application). You can find them on our websites. Use about 1 % of the total weight of the rope to apply.
Re-lubication of ropes is always a good idea. 1 or 2 times in a lifetime of the rope will do the job. For davit /cranes on lifeboats you need to apply more. Please use special steel wire rope lubricants which penetrate into the core and keep the outer strands visible for inspections. You can find them on our websites. Use about 1 % of the total weight of the rope to apply.
Depending on the application if the manufacture knows. Or if we know what the application is. We believe that for standard rope like we explained in this seminar NT55 (Nyrosten) is a very good standard rope grease to be used during manufacturing.
Depending on the strengh (rope diameter) and length …. But also on the pulling winche. Please always use a massive and rigid rope like 6x19s+steelcore or 6x36ws+steelcore 8strand rope will be more flexible but have greater elongation.
We will do more webinars on steel wire ropes during this year, the dates are not set yet but do expect at least one more before summer holidays. Some of the upcoming topics will be inspection, lubrication, sheaves & drums & end terminations. Please look out for coming invites!
A special webinar coming up soon: discard of ropes. It also depends on rules in your country. So we will focus on the standard ISO 4309.
There can be a very, very slight difference between left and right handed. This is due to the spooling of the traction winche of the closer, and then the left handed will stretch a very little bit more. Normally this wil be no problem.
