The correct choice of rope type depends on whether the Ascender is being used tolift or lower equipment or personnel.

Rope recommendations
Rope recommendations for the ACX Ascender depend on the type of application, whether personnel or equipment lifting

Equipment lifting
The ActSafe Equipment Lifting Rope (ELR) is the only approved rope to be used in the equipment lifting system and can be ordered at ActSafe or your ActSafe distributor.

Personnel lifting
All ropes that are used for personnel lifting must be certified to EN1891A with a diameter of 11 mm and should be of a solid construction.
ActSafe recommends using ActSafe rope, Teufelberger Patron Plus or Skylotec super static R-080 rope as we conduct all our testing with these ropes, we know that they work well with the power ascenders.
A rope testing procedure, in case you want to perform your own suitability tests and use another rope, can be found at our website. The reason for having this rope test is that especially softer ropes turn out to be not suitable for the use in ActSafe Ascenders because they have a tendency to deform under load and should be avoided because of poor grip and the risk of getting jammed in the rope grab system. The rope test is not a 100% guarantee that the rope works well every time in every condition possible but it’s a very good indicator.

It is recommended that only pre-soaked ropes are used with ActSafe Ascenders. New ropes should be put in cold water (<40°C) for 24 hours and dried slowly afterwards.

This will make ropes more suitable for use in ActSafe Ascenders for two reasons:

  1. 1. Rope density

    Pre-soaking makes ropes denser. The fibres will absorb the water and will shrink when drying. The result is that all fibres become more densely aligned and the sheath sits tighter around the core of the rope. This will make the rope more solid and will consequently result in less mantle slippage and deformation and thereby lead to better grip in the Ascender.

  2. 2. Oil dissolution

    During the production process some oil is added to the rope fibres in order to reduce the friction between the individual fibres. When soaking the rope in cold water some surface oil in the sheath of the rope will dissolve. This will contribute further to a better grip. Do not soak ropes in warm water, this will lead to greater dissolution of oil, which will have a negative impact on the rope properties.
