Interesting enquiries #3

Hello, we are hoping to inquire about a possible solution to a cliff we need to have guests climb up and down. The vertical height of the cliff is approximately 325' high with a slope of 45 degrees. The cliff we want to access is located in the Canadian Arctic, so there are no trees to secure ropes onto, and the ground is semi-permanently frozen so driving stakes into the ground will only go so deep, then you reach permafrost.

We wanted to reach out to you to see if you have a product/solution to our obstacle? All of your rope bridge products seem to be for a horizontal span, while our's is more of a vertical rise.

Treehouse Life response/solution:

#1: “I believe that there is a solution for you in anchoring to the ice or combination of rock and ice. There is an interesting article here and we could build on this research - - using ice cams or an ice screw system. Both are designed and certified for this use.

There is every possibility that we could get to a fully load tested and certified safe working load for these anchors. Again, it would not matter where these anchors were in relation to the climbing product as be could create a system from the anchors to two [or more] points the correct distance apart and suitable location to suspend from using suitable rigging screws and approved combination of carabiners/ropes.

We then also have exclusivity with our products on super-ropes with certified break-loads up to 944 tonnes:

  • Material: Heat-set UHMwPE with polyurethane coating

  • Construction: 12-strand single braid

  • Extreme strength-to-weight ratio

  • 15✘ stronger than steel

  • 20✘ lighter than steel

  • Safer than wire (low recoil)

  • Hydrophobic fibre (no water absorption)

  • Floats

  • Low creep

  • Easy to splice

  • Resistant to kinking

  • Maintains high strength around tight-radius bends

  • Exceptional UV and chemical resistance

  • Abrasion-resistant coating reduces likelihood of snagging and provides superior winch drum grip

  • Low elongation [3% at break]

We could then establish a large surface Rope Ladder, perhaps using slabbed round timbers with non-slip surface - fixed and stabilised in place on the load-bearing ropes and perhaps a large hand-held knotted rope for grip and pull. We could also perhaps create a rope [plus netted - safety netting] balustrade, if required.”

#2: “Solution is that we use a version of our ‘floating’ Rope Bridge system, where everything is inbound on two [or more] ropes - this will allow for round log timbers [rather than flat timber ’slats’] inbound on the ropes.

We use round log timbers for our Log Rope Bridges, where there is a gradient incline from the ground leading up into a ’treehouse’ or platform. The logs allow to step through the gradient as ’steps’.

The ropes are hugely structural and have certified break-loads [15x stronger than steel] plus only 3% elongation at break-load.

Also, inbound on the system are upright rounds [pair at each end] which are fixed and anchored to prepared large round logs [also inbound on the system], using scalloped and structural bolted joints. The upright rounds at each end are braced with 45º round timber beams, also on structurally impressive scallop joints to large round logs, inbound on the system.

The upright rounds at each end then allow the installation of rope hand-rails and balustrade [both sides], all under tension.

The whole system would be anchored [and backed-up] at the top and bottom, also once we have a suitable anchoring system - at a number of places through the incline.

The walkway will NOT be held above the ground, as in a Rope Bridge or Log Rope Bridge, but will form a ‘walkway’ sitting on and supported by the ground through its whole length. Guests will be walking step-by-step, log to log with both hands on a tensioned rope balustrade hand rail either side, as though walking through an ‘Indiana Jones’ Rope Bridge, but zero ’sway’ or movement because the whole walkway will be on the ground and following the contour of the ground.

So, a familiar ‘Rope Bridge’ system - with a regular install procedure. Full support through the whole system through the whole length and incline. Anchored at top and bottom [using a system already suggested - using climbing principles and certifications for load].

Benefits will be that there is a high level of certification for elements, despite a very unique project. Importantly, a zero-impact solution that provides the function - looks awesome, but can be removed at any time without any impact to the natural setting.”
