1) With polyester rope:
Colours: white, black or olive green
Tensile strength rope: >10,000 N
Tensile strength rope with mounted rungs: >500 N/rope
2) With aramid core, braided with polyester sheath:
Colour: white, black , olive green
Min. tensile strength of one rope: 13,000 N
Min. tensile strength of a single rope with mounted rungs: >800 kg
3) With aramid core with Black Technora sheath:
Min. tensile strength: 16,000N
Min. tensile strength of a single rope, with mounted rungs: 9,000N
The life span is highly dependent on the use.
The combination of use and storage should not exceed 15 years.
Hanging outside will cause a certain amount of UV degradation.
Polyester has a good UV resistance.
Black Technora will lose 35 % of its strength when exposed to 100,000 hours of sunshine and is therefore less suitable for permanent outdoor use.
If the sheath is seriously damaged, the ladder should be taken out of use.
A rope ladder is not personal protective equipment and users must be protected at all times by climbing rope and a climbing harness with an anti-collision device.
The rope ladder, regardless of the number of elements, may only be climbed by two people at a time.
