Hey Dave, we did a some drop tests on a croll+hand ascender on the weekend and the croll tore the rope on just a 20cm drop but the hand acsender prevented any more movement by arresting the fall-as the uni would in your system. This was however with very limited rope in the system.. I have the croll and the furura chest ascender and whilst i vastly prefer the futura due to its size i have heard they dont do so well in tests, however, that is hearsay as i have never tested it myself.

the drop tests we did on the weekend showed that the wrench is really safe. The croll and hand ascender tore the rope on a 20cm drop, the RW took a 2m drop with no problems. The footlock prussic was welded to the rope on a 70cm drop. As Ian said, a doubled rope is still a single leg of line as opposed to a double rope system that has a seperate line for backup -ie rope access. I can definetly feel a rapid change to SRT from friends that i climb with regularly

Hey arborholic, what are the reasons for not allowing it at work? Really interested to hear company arguments for and against. I really struggle now to find reasons for not using it let alone it being allowed. Any help I can be, just ask bro. We will be videoing more drop tests and comparisons soon
-
Yes thy can easily be installed from the ground. Just install them the opposite to normal so the unspliced end goes through first bro
-
Hey dave, If you dropped into that surely the croll would be the primary and tear the rope and the UNi would be the back up above the rope. ESP if the UNi was near the croll as your rope walking. Interested to see if you think different. Cheers bro, drew

Pelican cases are great but remember there only waterproof when stored the correct way up- on there side they can still let water in. What about storing a few bags of rice in the container to absorb the water!!

Nah I've seen some glorious macrocarpa but possibly the wrong thread for that conversation....

dont think youll get an answer to that question bro, what one man likes, another man hates

sick ropebag:) nice work tony and di!

the dmm pinto is the only pulley (that i know of in tree work) designed to be spliced onto bro.
-
get another pulley (pinto RIG) instead of the tensioner maybe

Australia is it really worth it??

well ive got the NZ class 2 Truck license up to 16tonnes (maybe 14, havent checked since i did it) is that the same steve? -
I think the deal just got sealed:)
-
I tried it but needs a pulley from my very limited experience on it. I did see a prototype pic ages ago with a pulley built into it from morgan

hell of a shot with the throwline there bro!

what about short excursions over from NZ steve? -
the reason for this was people saying that the wrench isnt rated etc.. i always thought it would slip a bit but then arrest the fall. but thinking it would do that isnt really good enough, id heard rumours of it just sliding til you hit the floor so wanted to see. I 100% have faith in this system now and can justify telling fellow climbers its safe if not safer than current systems being used. and cheers for the offer mate-old carabiners and rope are perfect, lets be honest its what the majority of us climb on in the real world. As much as its great to see a rating of say 22kN for the day you bought it, whats it like after being used in day to day work after a couple of years or a big drop. and now back to the wrench discussion......

Anything thats used in tree work bro. I'm not trying to be scientific just recreate some I the situations we get in doing every day tree work. Mainly doing straight drops but would love to do swing drops and also get some trees that are going to be removed and see what it takes to rip anchor points out. Treetools have donated gear to break, fellow climbers have lent rope guides, ascenders etc. there's nothing like seeing the gear you use being tested and knowing that it's super strong and also seeing strong gear breaking at low figures due to how we use it in diff configurations. Makes you think aye. The most commonly accepted srt access is the tree frog but this was the only one that really damaged the rope. I think every arb camp should have a gear destruction element, it's something I'm going to push for hear at least
-
Keen as Ian but like I said on the fbook page- I've only got so Much gear I can afford to break in tests, always available for donations of used/new gear to test:)

Srt and choke your line onto limbs

Did some drop test today on the wrench, vt using ocean poly. Dropped 80kg from 1m and 2m with the hitch set real loose and wrench just flopping about. Got no more than 10mm of slippage before total arrest of fall, still good to climb on straight after. Croll+ascension tore the cover from the rope on a 30cm drop. Footlock prus melted the rope to the ap cord on a 60cm drop, couldn't move it after this, had to peel it off the line. I'm thinking the wrench is a pretty safe bit of gear:) Only managed to get a few pics and video as didn't charge my camera battery, school boy error but good reason to do it again.
-
perfectly safe but youve got to climb to place it and retrieve it. try it on the small ring of your friction saver, gives you the chance to retrieve if rom the ground and set from the ground
-
so how long you going back for bro?
