Rescue pulley

Familiarity:
I've used it once or twice and have initial impressions

Well I havent had to rescue anyone yet. But practicing with pulley and a 3:1 system went fine and dandy. I purchased this pulley for crevasse rescue since it is so light. I would not buy this if you are using this for more than rescue and/or for frequent use. It is very basic and will not handle a lot of abuse.

Solid pulley

Familiarity:
I've put it through the wringer

I use this on my drift boat to be able to lower and raise the anchor easier. I am using it outside of it's intended use but nevertheless it has held up great in a very wet environment with lots of moss and other debris constantly trying to impede it. I have had zero issues with it.

First Impressions

Familiarity:
I've used it several times

We picked up a few of these to set up a pulley system for weights in our gym in the garage. So far, they work great! They are super small and light- they do seem to be a little squeaky when you have real heavy weights, but they still do work. For any sort of hauling, it seems like they would be an excellent choice. For users information, they will accommodate a rope up to 11mm.

Good Pulley

Familiarity:
I've put it through the wringer

I use this pulley for a weight removal system for my hangboard. For this application it has worked great. At most there has been about 40 lbs across is at a 90 degree bend. Nice and smooth for that use.

Great!

I got these for a lesson on simple machines. They work so much better than the cheap Wal-Mart ones and make it much clearer for students to see (and feel) the mechanical advantage.

Rescue Pulley

Familiarity:
I've put it through the wringer

So, I own 3 of these and a few other pulleys. These actually are prussic and tibloc minding. They are fantastic with a tibloc. I paired the 3 up with 3 tiblocs and 3 BD ovals for my lightweight rescue kit. Plenty strong for what I use them for. The Nylon sheave is smooth. The guy that used it for the boy scout zipline was being an idiot. Always inspect your pulley before using it, not just "at the end of the day". It's not a double sheave metal pulley. Its a lightweight rescue/haul pulley. Use it as such and you will not be disappointed.

Light and cheap

It is my ideal pulley for crevasse rescue as it is so light and small. I never thought the fancier, more expensive pulley's were worth it.

What i was looking for, light & cheap

Picked this up for $14.95. Don't care that it has a nylon sheave. I will only use this for hauling systems in an emergency. Actually picked up two. I am curious to see how well it handles prusiks being that other pulleys are marketed as "prusik-minding." So we'll see. But as far as function, weight, and cost, I don't think there was a better option. I am partial to the Petzl and Black Diamond brands though. The picture I attached is of the newer pulley. At the time I write this review it looks like backcountry still has the old model pictured (maybe i'm wrong, sorry if i confuse!) It's pictured open & closed, with a Black Diamond Positron locking carbiner located between them for size purposes.

can i use this pulley in a tyrolean traverse situation? i might also use 2 at the same time just to make the traverse safer and redundant. let me know what your thoughts are. thanks!

This isn't a question, just a comment I think will be very useful for those selecting which pulley to buy: - This pulley (Petzl Oscillante) weighs 42g, and has an efficiency of 71% - The Petzl Partner Pulley weighs 56g, and is 91% efficient. Very slight difference in weight, huge difference in efficiency. If you know anything about hauling systems, pulley efficiency is huge- otherwise you'd just use carabiners instead (carabiners are roughly 50% efficient as pulleys). The Partner is clearly the best choice- If you're going to bother taking up valuable space/weight on your harness or in your pack to bring a real pulley, that's the one to carry. The Oscillante is, however, way cheaper, and better than a carabiner at least..

Dan, thanks for your keen eye and great input! I also carry a full-function, classic pulley on my harness for crevasse rescue and I completely agree with your assessment. Thanks again for keeping the Community informed!

We bought the Petzl Oscillante Pulley for...

We bought the Petzl Oscillante Pulley for our Boy Scout Troop with the intent to use it for a zip line. The rope was tied from a tree on one side of the gulley to a tree on the other side of the gulley. We created a rope harness that the scouts sat in and attached the harness to the pulley with a carabiner. The carabiner also had two ropes attached to it to pull it back and forth across the gulley. One rope given to scouts on one side and the other given to scouts on the other side. At the end of the day, I looked at the pulley and it appeared as in the picture attached. The rope had melted the pulley wheel and even started melting through the metal pin holding the pulley assembly together (thru the pulley wheel). When we first started using it that day, the pulley seemed okay on the rope. I believe that the rope was within the limits described. Any thoughts? This definitely didn't work out the way we had hoped.

Looks like at some point it stopped rotating then started to burn from the friction of the rope. This device is not designed for high speeds, its made for light rescue and for climbing (hauling gear bags) or other climbing applications. The plastic is not made to stand up to heat, i would look into something that is made for zip lines probably a metal pulley. I dont know of any climbing gear made for that fast of movement and that much friction. Good luck be careful.

Like Vern says- this is made for haul-lines. For a zip-line, you want a double sheave, steel and ball bearing trolley. The lack of bearings is what made the nylon sheave freeze up as it went too fast, got too hot and fused with the axle pin. Sorry you're not going to get off quite so cheaply with the real deal, but at least nobody got hurt, and with the right gear, you guys will rip. Here's a link so you can see what you need: http://www.ziplinegear.com/zip-line-gear/pulleys.html Be sure to inspect your rope, too.

Totally agree with the other two this pulley was not meant to be used as you used it. If you want to get this pulley dont be put of by this. This is a great light weight pulley. I use it as most do for a light weight crevasse rescue pulley and the plastic wheel is perfect for this job.

It amazes me that more boy scouts don't get killed from crazy scout leaders doing things they are not qualified to be doing.. Don't use life-critical gear for purposes it was not designed or approved for..
