Description

The pulley that makes it on any trip.

Don't let the Petzl Oscillante Pulley's low weight fool you. It handles loads up to 4kN, making it an ideal choice for crevasse rescue work and even lightweight hauling on a big wall. Because it weighs only 2 ounces, this Petzl pulley makes the cut even when you're going super light, so you'll never be tempted to leave it behind.

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

  • Gender: Male
  • 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.

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.

Be sure to inspect your rope, too.
