ROPE TYPE AND PREPARATION
The correct choice of rope type depends on whether the Ascender is being used to lift or lower equipment or personnel. Check with your ActSafe supplier or at the ActSafe website for the latest list of suitable ropes.
Rope recommendations for the ACX Ascender depend on the type of application, whether personnel or 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.
All ropes that are used for personnel lifting should meet EN 1891 A with a diameter of 11 mm and should be of a solid construction. It is recommended to use ropes in ActSafe Ascenders that have passed our rope suitability test. A list of suitable ropes and the rope testing procedure, in case you want to perform your own suitability tests, can be found at our website or contact your ActSafe distributor for more information. The reason for having this rope list is that especially softer ropes turn out to be not suitable for the use in ActSafe Ascenders because 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.
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. 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. 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.
