Looks like a slick device. I'm not sure of how much it weighs, but looks like it would be really quick to set up and fairly easy to lift rescue someone. Thoughts?

Quick where are the ignoramous's who were so busy posting in the rescue pulley crevasse thread going to come tell us that those pulley's are too small and won't work! instead of the simple fact that pulley size efficiency is based on rope size due to internal rope bending considerations. You will note they used small diameter rope on small pulley. Creating a tidy 6:1

This is essentially no different than the system you have to make for yourself in a 2 man rope team when/if the guy in the crevasse is incapacitated where the 2nd has to climb down and pull yourself and the other guy out and more importantly get over the lip. This device certainly does not look lighter than simple pulley system that one needs to have anyways. One already has to carry prussics so this device is supposed to be used in liu of pulley's in all situations... Add in said pulley's have far more setup options whereas this device will be slow as well during the pull. Won't see me buying one. Its expensive, and slow to pull someone out. Quick setup though.

The vast majority of crevasse "rescue" situations aren't really rescues at all. Generally a simple lowered loop will suffice or wait till the guy half in wallows himself out via prussics. Will I carry an uber expensive piece of gear that will generally never get used? No. This falls under the billing of carrying a SAM splint and a giant first aid kit. Maybe we should all carry kitchen sinks as well, you know, "Just-In-Case" we might need it.

It looks heavy, but I don't see any info on weight or on what size ropes it works with. I might pay the price if it was just as light as my current setup, which seems unlikely.

Why would it be slow, Wastral?

6:1 and can't be changed to 3:1 or 2:1. Means you have to pull 2 or 3 times as much rope through and likewise have to reset 2 or 3 times as often. = SLOW

Add in rope stretch and it becomes more like 2.5 to 3.5 as often. In my experience, one generally wants a 3:1 or 2:1. Yes, I have made a 6:1 when I needed to pull my "unconscious" brother out of a crevasse during practice, but otherwise nope.

TO make this truly effective, combine it into a belay device/ascender and therefore it becomes a dual option. Then we are talking. I don't see any reason it couldn't be. No, one wouldn't be saving huge amounts of weight, but it all adds up. I hate specialized gear. Likewise, it could, possibly, haven't thought through ALL permutations, be used in lieu of all of your prussic loops as well. At least cut down number of prussics by at least 1 if not 2 or all 3 as one can still make Kleinheist etc out of slings yadda yadda. If the above is true, then it could be stated as being a one piece tool that does ALL the above and therefore be LIGHTER and overall SIMPLER. Gotta think about it. EDIT: And no I don't mean pass a normal rope through the 6:1 when belaying. Think more like a gri-gri. There is a lot of weight in a pulley/gri gri/belay device that is only there to attach said device to a carabiner etc. If one can combine all these metal parts into one device. Yum. I think I would have to sign me up for that.

I see what you're saying. I personally can't pull my "unconscious" partner out of a crevasse without a 6:1 in training but so far we haven't had an actual situation occur.

Wall Hauler's camming unit "does" have a limit of 180lb per the manufacturer. It's up to you to decide if that's a number you must follow.

I have seen people use it for hauling on big wall with some heavy pigs, but I can't say how much those pigs weight.

Not disagreeing with you, just want to say that the number is manufacturer's recommendation. I personally wouldn't use wall hauler or mammut rescYou, but hey... to each and his own right?

Neither has Wastrel..... Just tons of SKI AREA PARKING LOT FALL scenarios.



Regarding the OP, if the above Mammut piece of gear were to be implemented, EVERYONE on the team must be carrying one as with all other equipment the TEAM decides to utilize in the event of a Crevasse punch through and fall. Something that needs to always be in mind when applying all this fancy gear.






PS: Here is a device that has been around for two decades, is 1/3 the weight of the new Mammut rig, half the price, and can serve as the Primary ATTACHMENT Haul Point in the "Z". Of course WASTREL will deem it a piece shit and totally ineffiecent. Regardless:




More importantly, the adage of "KISS" should always be applied to any Crevasse Rescue Set-up Kit. Time and Efficiency are of the essence.

You advise people to carry a wall hauler device for crevasse rescues?

Micro/mini traxion might not be a bad idea if you have one..but any light regular pulley should do the job if you know how to use it.

Both have the SAME specs/ratings for the Camming Spring and Connecting Pin.

Why not?




PULLEY'S not PULLEY!

You will require prussiks as well.

In the photo it looks big and heavy, but maybe it is much smaller than it looks in real life. Have not seen one of those in person. Just know how nice/small the microtraxions are! Really like it.

Thank you for clarifying, Rick! Seems like a good tool as well.

Maybe that is why one should first have prior experience utilzing a piece of gear before making a comment such as your previous one regarding the use of it in this scenario.




As I noted above, I have hauled over 300 lbs of Pigs on a single WH on many occasions.

One needs to remember as well, that any load from a fallen crevasse victim will be a STATIC load, almost exactly like a Pig/s on a wall.

The Wall Hauler only weighs 2oz's more than Mini Traxion and just under 2oz LESS than the more comparable Traxion.


Again, ALL three have the similiar max SPEC RATING for the CAM SPRING LOAD.

---------------------------
Personally, the most efficient way to get out of a crevasse is to not fall into one. That's my preferred method and it works great!
