I just picked up the petzl bridge adjust and some open rings to convert my early model Sherrill Edge harness to dual bridge setup, with one adjustable and the other fixed. Plus I will now have useable hip rings. I have not decided how exactly I plan on using it. Possibly how you are talking with...
I use a gri gri in a rads system as part of a long multi purpose lanyard,
And a petzl ID in rads for my main climbing system. I have no complaints it’s not necessarily the fastest or most efficient but very effective for my uses...
I agree with Brocky the gri gri is a bit tight on bend radius...
I always make it a point to mention during estimates that you must speak to the neighbors about trees that are shared or not yours. Most take care of it, sometimes neighbors even come outside to discuss. Other times I will drop a note with a card, That if they have any questions or concerns...
I have about 150 or so wrenches and 750+ sockets that are all nail polished they are color coded for easy ID it has worked really well and lasts a long time... red for SAE, blue for MET, white for impacts, green odd ball...
Don't worry I have a petzl vertex vent, same color scheme same reason... As long as I can see the guys on the ground they'll survive another day... the heat is sometimes a thing tho...
Best of luck in your hunt..
I carry a small tool box, filled with freshly sharpened chains 2 for each bar size, bar nuts, plugs, fuel filter, extra scrench’s, carb adjuster, stump vise, files, and a timberline sharpener.
What ever keeps things moving on the Jobsite is the best solution....
Occasionally I will touch...
I will agree with Brandon...
I have three pairs of Hoffman’s one pair of leather pole climbers which are my goto for all of my spur work... and 2 pairs of winter pac caulks. They are by far the best boots I’ve ever worn... tough, comfortable, warm, reasonably priced and made in the USA. What’s...
I've had similar instances with lanyards over the years, gaffing out and sliding down. But I've always recovered before impact... The easiest solution was to use an extra prussik and carabiner on your lanyard as a cinch around the stem...
early on, I repelled out of maybe a 40ft er...
It won't get you a ton of tension, but with the rope and a Porta Wrap only you can still get a 3-1 with capture. You tie off the tree (being removed) tail goes through PW leave some slack tie an alpine butterfly aprox 10-30 ft in front of PW. This distance depends on the intended pull length...
By recently acquiring a 3/4 CMI Block, in addition to our other big cmi, I now have a great set up for that although we haven’t tried it yet. We’ve done it a few times with the smaller 5/8” block.
Thanks for the refresh. I am going to try an implement that on an upcoming job with the bigger...
I don’t have to do it to often, but sometimes well take out a large limb 16-20”dia or even a full lead in the 2500lbs range in one piece especially from a oaks with overhead rigging. 5/8 stable braid 2 spider leg balancers. I probably should and will get a 3/4” line for jobs like that, but I...
Safe working load includeds the total force of the system. Based on the manufactures tensile strength or ABS at a set rating usually 10% or 20% 10-1 or 5-1 sometimes it’s 4.5-1 others it’s 7-1 each piece has different engineering to it. There is in my op a safety factor built into their design...
That is correct, At times doing big picks having big block and 3/4 rope can come in handy, for some static loads you can also use 5-1 WLL but those decisions should be made on a case by case basis...
That's the main reasons I like them as well, I have an Omni block 1.5 loopie, but I only use it for light duty "non dynamic rigging" and as a midline attachable redirect. It work's great for that.
People have long since debated whether the Omni's are pulleys or blocks........
Regadless of what...
A Block generally sees twice the force regardless of the rope in the system.
And The sling that attaches it should be matched accordingly.
If It’s a 30000lbs tensile strength block with a 6000lb work load that’s @5-1 safety factor with both legs of the rope. So on a single leg there should be...
Cool video
Owscott I totally agree the lack of a second tie is important on especially big trees when you can’t always see... of course it’s best to check and recheck your position and cuts, but a backup never hurts.
I don’t do much crane work, but when chunking down big spars I like my 5/8...
