    Tree Company Acquisition

    Was acquired by Bartlett down here in Pisgah Forest, NC in 2018. I agree with pretty much everything posted above, but ultimately left to pursue a better wage for my skillset and experience (this is probably dependent on location and office). I've been with a small local outfit last year and a...

    Speed line came untied at the ground

    I think about zip lines primarily as force multipliers. First time I set up a slackline we ripped a fence post out of the ground. Where on the skid was it attached? Was this clove was tied at the terminal end of the line? I always try to keep the working leg of the clove on the inside of the...

    What special training is required for the use of small diameter lines?

    I'll have to meet him quick, putting on my respirator and relocating to CA end of October. Bob had a lot of great stories. I love hearing the older generations, arborists, or rock climbers for that matter, talk about their early days (or anything involving helicopters!) Back then I was not the...

    Tests of Zeppelin vs Double Fisherman's bends?

    A little bulky with cord perhaps, but have you tried a water knot (overhand retrace)? I've had them totally fused in webbing, and rolled the knot between my sneaker and a car mat with great success

    certified arborist logo usage

    You'll get a patch with your paperwork, found it needs some sewing and the iron-on part is worthless. You can order more stickers/patches from the ISA of course. Worked for a company a while back thay had the ISA logo small on the back of the shirts. Not sure how legit it was. They didnt want...

    What special training is required for the use of small diameter lines?

    I got to work with Bob Webber a few years back, he came to do some contract climbing for the company I was working for at the time. Incredibly grateful I got to spend a few days with him. After he set his line with a crossbow and threaded rods (he changed the weight by adding or subtracting...

    What special training is required for the use of small diameter lines?

    I think there are actually smaller ropes now rated as single lines! (as opposed to twin or double rated lines) 9.5 seems to be the new rock climbing standard, not many 11mm offerings out there these days. Don't even know anyone with a >9.8mm dynamic line.

    What special training is required for the use of small diameter lines?

    These smaller diameter ropes have less surface area, and therefore run much faster and provide less friction when running through climbing devices. I've always taken this faster handling to be what is implied in that standard. Rock climbing ropes are getting outrageous. Rapelling on a 8.7mm...

    Petzl Adjust as a lanyard?

    Interestingly, this configuration is auto-locking, while something like a gri-gri is only braking-assisted. In rock climbing, you can belay a second below you directly off the anchor with your rope oriented similarly in a belay device. However, it is very hard to undo with a load as others...

    Cobra cable inspections

    For dynamic cable, noting tension. I've seen the shock absorber being squeezed out between the cable strands on long spans with large loads. Also noting how much "collar" remains on old cables- the bight going around the tree. Is there room for growth yet? I've seen lots of old dynamic cable...

    This is a serious crane!

    Reminds me of the one earlier this year that had a block failure in testing. Incredibly bad day https://www.maritime-executive.com/article/video-giant-crane-collapses-aboard-new-offshore-installation-vessel

    Sick! Living and working in disaster areas is tough, glad you had something else to focus on for a bit. @Anawan rids a huge southern red oak of some pesky deadwood over comm lines

    Rattlesnakes in trees?

    Cool! Encountering a rattlesnake or box turtle is one of the greatest joys of the forest. I wouldn't be surprised to see the odd one in a tree, but seeing one in the upper canopy would be strange. I wonder if here in the eastern US, where tree hollows are such important bat habitat, if that...

    Today....

    That's not even the half of it. Clients processed all the brush and firewood and had a smorgasbord of food for us. We didn't bring a chipper and we didnt even get the rakes or blower off the truck. We either work with this 65t or that company's 30t truck mounted boom, and the company I work...

    Today....

    It's a 65 ton. It's got the most stick in their fleet, 130. We were making picks across the garden and down in the goat pen with 110' of stick out, but we had it all the way out so I could do a wee bit of tip weight reduction on a big cherry. No big picks today, just needed the reach...
