SRT vs DDrt comparison table


Island Lescure

Recommended Posts

Hello from India,

I have not been keeping track of what the two systems are now called but I am sure you can figure it out. We call them dynamic and static rope techniques.

 

I have made this table for our climbing students to help them decide which system will help them for their tree climbing tasks. Do you have anything else to add to it? If not, I hope the table helps you see the differences between the climbing systems.

 

Cheers,

 

Island

 

SRT

DdRT

Faster & easier to install (if using base tie)

Less gear required

Faster to move up on

Simpler rope management

No friction through crotches because rope is static

Easier to move up short distances (no additional gear required

No cambium saver, less chance of getting stuck, throw line snapping etc

Added friction when passing over crotches, redirects or any other branch union

No branch isolation required (if using base tie)

You have to retrace your route through the tree when coming down, otherwise the system will not be retrievable due to too much friction

Pantin, knee ascender, hitchhiker or other friction device, more gear intensive (expensive and more gear to inspect)

Easier to free climb a tree or advance up main anchor

Comparatively new, globally less recognised, ISA only slowly integrating SRT (safety regulations)

Easier to limb walk

Can tie main anchor in to a smooth vertical stem

 Sorry to have to tell you mate, that's got nothing to to with your weight, unless you're saying you're so light you couldn't descend!
