7-Flex® Wire Ropes

We offer 7-Flex ropes for many applications that currently use 6 x 19 or 6 x 36 classification ropes. Their operating characteristics are similar in many ways to 6 x 36 classification ropes. Typical applications such as container cranes, logging portal cranes and sawmill carriages have reported increased service life with the 7-Flex.

The 7-strand construction offers improved resistance to bending fatigue compared to a 6 x 26 due to a combination of the outer wire size and the seventh strand. These products are also available in a TUF-KOTE®/ PFV option to further enhance their service characteristics.
