SINGING Rope Wrench with the Lock Jack!
We did a 4 leader 100 plus footer White Pine today
(top and side reductions plus crown clean plus cable 3 leads) 8 hour job in about 6 hours.
I did three leaders to my apprentices one leader. Scott ascended Srt and switched to drt for the work around and down. I Srt'd 1/2 way up and drt'd to the top and srt'd the rest of the tree.
The Singing Rope Wrench by my calculations saved me a atleast an hour (but I think more like 2 Hour) in time plus the smooth and easy positioning.
I was able from one tie-in-point to do 3 of the four leads with great effeciency due to the zero friction of the redirects and rubbing of multiple limbs plus no retie-ins.
Very happy with smooth descents and positioning, at times near horizontal positioning. THis is much easier to do with Singing/Lock Jack set up. Love this big time. It is very cool experience to get to those periphery horzontal tips with a lot less effort.
On the ascents I find it is easier to
1. place a handled ascender/footloop below the wrench
2. insert rope into Croll at the sternum
3. disconnect the Lock jack and rope walk
Only down side is the slack tending. It takes a bit more effort but I have that pretty much figured out now as you can see above and for shorter ascents it can be pushed along with a little effort similar to a traditional drt system.
All I needs now is the push/pull pin for quick install or removal and we will have an awesome money making climb system for the New Year.
OH! It only took one big tree/tactically difficult climb for the Singing Rope Wrench to pay for itself.
I operated an Aerial lift truck for over 5 years as a municipal employee at one point in my career and I always said a good climber will KO a bucket truck, evident by the many many times the bucket was abandoned for rope access.
I believe with the Singing/Lock Jack system we are looking at a champion system. Perfection is getting close.
Thanks Kevin and Luke at TreeStuff.com for having the tree acumen.
In case you are wondering I fly on the Velocity by Samson and have the Singing Rope Wrench full on tight with the tether about 6".
