I'm a big fan. Way better than the old rock exotica wall hauler. I've heard a few bad reviews over at supertopo, but I've had great luck with it. The mini traxion is great too for lighter loads.

I really can't complain about the traxion so far.  The pictures and descriptions of the failures do bug me though.   So far I've never hauled more than about 120ish lbs with it, but no problems.  Also jugged with it holding the load with no problems.

I'm gonna give the pulley plus ascender system a try next week.  We'll also have a traxion for comparison, so I'm very curious to see how it works out.  I picked up of of those 3.5" monster pulleys with the big hole in the middle.  The big hole fits a large Petzl pear biner just dandy.  You have to put your ascender on the biner, then clip the biner into the pulley, but it works without undue complexity.  I think I would have been better off just getting a ball bearing 2.75" CMI one however.

What???  Guess I didn't hear about this.  I was just asking 'cause I had access to one fairly cheap; wasn't aware they had "issues".

I've used my mini ascender/pulley combo and it is a bit of a hassle.  I'm just expecting to drop the damn ascender since it's so small and "fumbly".  I otherwise use my standard ascenders and they work a little nicer overall, only I hate being forced to free them up when I'm using them.  Just something about a dedicated hauling device seems appealing.

I wouldn't sweat the issues of it. The convenience and ease of hauling far outweigh the possibility of problems.

Go searching on supertaco.  Pete was the most vocal of the crowd, so take commentary with a BIG grain of salt.

Here's one thread:

I'll sum up the issues.
1. If the rope is too fat (11mm) the cam does not engage as well.
2. If the hauler does not hang straight from the anchor. Like if you clip it straight to a bolt and it is kinked sideways, the cam can fail to engage.
3. If you don't clip a biner through the holes in the bottom you risk catostrophic failure, should #2 occur.

I have probly hauled 100 pitches with it and had it "slip" on me once. I had it clipped straight into a bolt. Luckily i was on the opposite end of the line with a gri-gri and it wasn't much of a big deal. Since then i allways use a sling to clip it to the anchor. It needs some freedom to twist and spin as you haul...

I had a friend who had one of the side pannels disengage and his haulbag sucked him down into Hollow Flake. He got pretty beat up and they bailed. He claims he had a biner in the bottom holes, but I somehow doubt it.

Personally I am a fan of the Pro and will continue to use it, like anything else...rig it properly.

The Pro-trax is a poorly-designed and even-more-poorly-engineered piece of shit that will eventually fail on you in the middle of a big wall when you happen to need it most. 

Is that vocal enough for you? 

Spend the extra thirty bucks and buy a Kong Block-Roll.  I can get you one if there are any to be had in North America, so email me if you're interested.  Those things are the bomb - super-solid and built to last - plus hugely easier to haul with due to better bearings and a bigger diameter pulley wheel.

Jeez Pete, you keep making that offer, but you don't reply to the emails when I say I want one.

I'll be in the valley from may 20 to june 2, if you have one for sale (and I can find you) I'll buy it.
I'll be in a white minivan with BC plates, probably in C4 if I'm not on a wall.

I'll contact Kong and see if I can source a Block-Roll for you.  They said they might have a few in North America by springtime.  I can arrange to leave it with my friend at the Ahwahnee so you can pick it up any time.   So fire me off an email tomorrow at my user name here at hot mail dot com.  Cheers.

Email sent, thanks pete.
hopefully I can pick it up before I get on the Nose, the bigger pulley should make hauling those slabs way less crappy...

Has anyone heard of or used the Ushba Hogwauler?  I don't have any personal experience with it, but it sounds like it might be a pretty good devise and weighs almost half as the Kong Block Roll.  It is rated for live loads and the cam doesn't have any teeth to shred the rope.  The price is about the same too.

I was curious, so when googled the Hoghauler and found the following review/comment:
"I probably use this in very different circumstances to most (entertainment rigging), and it suits the task very well. The main reason I bought it was for the toothless cam - far less wear and harder to jam the rope by pulling the knot into the pulley cheeks. The finish is a tad rough and it's kinda large too, but the titanium keeps the weight down and boy does it look cool!
Although it is not relevant to my application of the device, it seems as though there is a major issue with shock loading this type of cam, be sure to check out "http://www.hse.gov.uk/research/crr_pdf/2001/crr01364.pdf" this document before deciding to buy the Hogwauler or any similar device. "

It's my recollection that the Lyon report was largely discredited as being very biased, and alarmist as it related to claims of ropes severing and being damaged.  Anyone know more of the scuttlebutt?  I'd tried to find it before, but it had been pulled by every site I could find, that is the first live link I've seen.

I'm not so sure I buy into all the bad the hype about the Pro-Trax.

Pete, can you elaborate on why you think it is going to explode on you? Did you have a bad experience with one? I'm sure I read it before, but refresh my memory...

The Pro-Trax requires a careful set up, just as any other device. A gri-gri for instance. I'm pretty sure every misshap with a Pro-Trax has been either user error, or using the device other then it's intended purpose.

I have haulded a fair number of pitches with mine and it has never failed me.

As far as I'm concerned if you need a bigger/heavier pully for your load then you have a little too much shit with you.

Having climbed more than 15 Yose walls with the pro-Tax I think I can shed some light on the the issues. 

the Pro-tax is a great time saver, hauls with a more than reasonable amount of efficiency, but is also more than a little temperamental at times.  Lambone hits the nail on the head when he talks about a degree of freedom and ropes that are too thick (11mm or more). 

More than anything rope angle is the primary component of failure for the Pro-tax.  As PtPP and others have reported, there is too much space between the side plates and the pulley wheel, allowing the rope to "derail" off the pulley wheel.  However, when properly aligned and allowed to rotate with the movements of the hauler or bags that are being lowered out,  the Pro works prefectly. 

IMHO there are two every important things you need to remember when hauling with the Pro-tax.  First of all, use a Petzl OK locker.  It's an oval and its designed for the Pro, allowing the Pro to hang straight on any biner or sling.  Secondly, you need to center yourself in front of the the haul, so you pull straight on the haul line and avoid any twisting action while hauling.  It's all about a certain degree of freedom.  Tweak that thing too far to the right or left while pulling on the pig and your asking for trouble.
