Ski pulk pullers?

Bought a new pulk this year -- and have been waiting impatiently for enough snow to actually tow it anywhere. Tried towing an old wagon full of weight up the street, for exercise -- but the neighbors already think I'm a weirdo, so...

If there's anyone else on here towing a sled/pulk for fun, I'd love to discuss what/where/why/how it's going.

I dropped some dough, and got a Siglin 6'. I was worried about storing/transporting that length, but it turns out they easily roll up long-ways, to fit in a reasonable sized cube box. Total surprise.

I'm planning to use a climbing harness to tow it, for starters -- but I've got a nagging doubt that it might not work as well as a dedicated harness. The design is kinda different -- way less padding/stiffness in climbing harnesses, and you have to jury rig a good strong point for the pole connectors.

Hopefully gonna have some more data after next weekend -- we finally have enough snow coming in, close enough to a road, that it looks like a good time to play with it.

Hey Ryan, 

I'm psyched, your psyched on training.  The only time I've pulled a proper pulk sled for "training" is with clients on Denali Prep Courses.  However I have spent many hours towing my kids around the mountains on a Thule Chariot and we drag tires on asphalt at the Alpine Training Center.

The problem with towing the pulk for training is that it's pretty un-fun. However if you are preparing for an expedition like Denali or a crossing in the Arctic, you'll find front-loaded sled dragging will certainly make the experience more enjoyable!

I've been experimenting with the harness that SkiPulk.com sells ( skipulk.com/product/full-ha… ). It's worked well the one or two times I've taken it out. Is that where you got your Siglin? Shoulder straps seem to help, especially when you're going uphill.

Well, I assume that 95% of what makes pulling that Thule Chariot tolerable is the, ahem, cargo? ;-) So I suppose the fun is where you find it.

I have some particular practical considerations, but it boils down to this: I often need to carry more weight than other folks, in order to make a trip happen. Heavier loads translates directly into more access, more freedom, and less limitations.

I've found that I can mostly manage a 55-60lb backpack on easy skiing, but it really does limit my movement options, pace, and endurance... And even 60lb just isn't enough to meet some of my trip needs.

Pulling a load is also limiting, but not as bad as the same weight in a backpack. I seem to move better with the pulk, even loaded up to ~90-100lb. Not sure how other folks feel about that -- maybe it varies?

So I guess to me, "fun" and "not fun" aren't even really part of equation... X weight is the price of my admission to destination Y, and complaining about it doesn't really change anything.

Yep, got my new one from SkiPulk.com... I bought their pole kit too. So if i decide to switch to their harness, it's just that one piece I need to change out.

I'll keep that in mind about the shoulder straps, too.

What kind of weight are you carrying, in yours?

I've done a handful of overnight or 2 night trips, so probably <40 lbs. Putting the weight in a sled instead of on my back does make things a lot easier whether I'm on skis or snowshoes. Having my center of gravity where it should be instead of raised up by a pack really reduces the effort required to maintain my balance, and I can ski at a decent speed on my way downhill.

Ive pulled a sled on two occassions going up to the hut at Katahdin in Maine and to some remote place in japan.  Both were mostly on closed, snow covered roads, but the final few mi and 1500 (?) vf to katahdin is on steep trail.  Worked fine and was great to pull so much junk.

I used an old BD couloir harness and chopped the leg loops off (glorified belt at that point).  Ive also attached the bars to the shoulder strap/pack connection.  Both cases i just used a voille ski strap making careful looks to securely fasten and avoid unnecessary bulk (and irritation).  

I also have the skipulk bars, used in both parallel and crossed setup, don't remember what was better for what, but definitely has potential to improve (i think parallel going up, crossed going down).

Obviously very common on denali

I pull the hip belt off my pack and attach the poles to the ice clipper spots on it. The trick is getting a solid attachment which I am still working on, but the last two years I have tied it as tight as possible with 4mm cord and it has very minimal play. Keeps the weight down a tiny bit as the hip belt is multi purpose.

We built the fancy fiberglass fence pole pulks (designs used to be free off skipulk.com but I think they're behind a paywall now) for Katahdin. In playing around with them/training, we tried using just a waist belt (i.e. a heavy fanny pack), but I found that the load felt un-balanced, and I actually enjoyed it a little more using a lightly loaded backpack (Osprey Variant) with the sled attached to the vertical-ski slots on the sides of the pack. I did run into some issues with the rotation on every step (snowshoes) leading to some irritation/fatigue of my hip muscles, but that was probably an under-training thing more than a harness thing. If I were to do it again, I might try and experiment with some of the ideas above (attaching to waist belt on the pack) to move the load closer to the body.

Thank you, everyone, for your input & sharing your experiences. I really appreciate hearing from you.

Some lessons from towing, this past weekend... Made it a few miles out with ~160lbs of gear + human volunteer. Great weather, great time, and utterly exhausted.

  • The Siglin 6' is pretty flexible in the long axis -- it can be rolled up for storage/transport. But with so much weight, it tends to bend awkwardly instead of properly tracking on turns and slopes. We tied a pair of aluminum crutches to the side rails, tightly cinched, which made it considerably more rigid -- and also gave the passenger a comfy set of hand grips & foot rests.
  • Backsliding on perpendicular slopes was a major issue with the heavy load, so we mounted an extra pair of climbing skins to the bottom of the sled, under the points of highest ground pressure. Worked great -- easy to clip & unclip, and the skins stayed in place really well.
  • Side-slope traverses were nearly impossible, even on the gentlest examples. The skins helped a bit, but we definitely had to be careful to square up perpendicular to any slope. The sled would slide off sideways, and tip the load if it got far enough over.
  • Hip harness (Metolius SafeTech Trad) didn't have nearly enough padding at the front of the hips, so the pressure got uncomfortable after a while. Also, the buckle style on those new SafeTechs is just horrendous, so difficult to cinch properly -- and nearly impossible to operate in gloves. Worst part was having to get in & out of my ski bindings, to step through the harness waist loop, every time I had to detach from towing.

So I'm looking at three main areas I'd like to improve -- long-axis rigidity, side-slope tracking, and everything about the harness.

Harness might be the easiest to solve -- I have some extra Osprey pack belts & shoulder straps that seem to meet the criteria. Or, I can knuckle under and buy the version that SkiPulk.com sells.

For the rigidity and side-slope issues, it occurred to me that I might be able to resolve both with a set of long (~5') fins made from UHMWPE angles (aka, "bedframe") bolted to the underside. SkiPulk.com sells short fins made from aluminum angles, so that's an option, too.

I don't know how much of this will affect folks towing lighter weights -- but maybe there's some crossover.

Not sure if this thread is still active but if it is; I have a long experience pulling pulks and thought I would add a few thoughts to it. I do long distance Nordic ski-touring, mostly in northern Norway and Sweden, as far north as 71° N.  I have more than 3.000km of dragging pulks around.  A couple of observations:  The Siglin 6 pulk in my view is a poor design (and poorly priced, to make one poor), the last thing you want is any flex in your pulk.  If you require a pulk that long then the 66" Emsco Beast would be an excellent choice, it will set you back about $50 (and does not require any reinforcement).  The Beast only weighs 7 oz more than the Siglin 6.  The argument about which PE material pulls better is kind of moot- HDPE pulls just as well UHMWPE in my experience, at any rate I put glide wax on my pulk if I remember to.  You can bolt UHMWPE runners on any sled if that is important to you.

My favorite sled is the little Jet Sled Jr. (43" long), I pack it with a 120 liter Rab duffle that also has shoulder straps on it, so I can put this whole bag-pulk ensemble on my back for short stretches where that is useful, like traversing paved roads.  I also fit a 20 liter square stuff bag in front of that.   I use the stock cover from the manufacturer to enclose the sled (goes over the duffle and everything.  I have installed four buckle straps of 1" webbing to hold the cover down.  To do this you must mount the brackets (alu profile) that hold the traces to the sled- under the sled (on the front slope) not on top, or else  the cover can't seal, they are better situated for pulling there anyway.  I can go two weeks autonomous with a 4-season tent and all food, fuel, equipment, and clothing using this sled.  I have runners installed on it, again because of bare terrain and roads.  I have an alu center fin, like a rudder, that I can bolt on the back to prevent any sliding on side hills- easy on, easy off with wing nuts (I do not use it much as the runners have aided tracking on side hills). I also have a back brake that prevents the sled from weighting me if (when) I stop during an ascent, it prevents the ulk from sliding backwards. That is my favorite accessory!  Simple to make: take a 6"x8" sheet of 1/4" HDPE, bevel one of the 6" ends to sharpen it.  Take an alu piano hinge, each leaf on the hinge should be 1" wide, (I got one at McMaster Carr) and cut it to a 6" length, bolt the non beveled 6" side of the HDPE sheet to it, bolt the assembly to the back of the sled using 3 x 1/4" machine crews and locking bolts.  Washers as needed. It should be bolted into a 1/16" alu plate inside the back of the sled to protect against impact.  For positioning: the flap should protrude 2" below the lowest part of the sled (including the runners if you have them installed)   I also designed a webbing with a buckle to hold it in the up position if I am skiing somewhere I might need to back up- on a lake or in a dense forest for example.  It works perfectly in all kinds of snow.  This sled is very easy to fly with as it is just about large-suitcase sized (I have to fly a few hours north to get to Scandinavia, sucks when they lose your "luggage"). 

For longer trips (or kitchen sink trips) I use a Paris Pulk with 2 x Rab 112 liter pulk-bags, so 224 liters load capacity.  A plus is the bags are blue and and the sled is orange so it is now in the colors of the world's greatest baseball team: The NY Mets.  I put some serious blue runners on the Paris, as the Paris sleds are thin and the bottom wears fast on rough surfaces.  They were pre-drilled and had all the hardware, made for a bigger sled, cut them to size bent them with a heat gun and bolted 'em on.  I am not a huge Paris sled fan- they flip over quite a bit (the slightly wider Jet Sled Jr. very rarely flips).  I used them on a trip last year from Ivalo Finland to Kirkenes Norway, they were fine for that trip as a lot of Finnmark is flat and many KM were straight up the frozen Pasvik River which forms Norway's border with Russia (good idea to have good land-navigation skills),skied to the three-country point where Finland, Norway, Russia meet- you can touch the Finn and Norwegian posts but not the Russian one..  One thing I do not like on the Paris is that the front lip points downwards sharply, maybe for structural reasons(?).  It plows deep snow, I am going to heat it and bend it up and then reenforce it with some thin alu sheet.  The Jet Sled Jr. handles better when skiing, much better.

Traces, attachments, and harnesses:  I have both the H-bar traces from Fjellpulken (I have two of their old fiberglass sleds in my garage) and the crossed-poll fiberglass traces like Skipulk makes.  I greatly prefer the crossed-poll system less slack and less chance of breakage.   My advice is if you have a spare 145 bucks just buy them from Skipulk, it will save a lot of cursing.  If not you can make your own.  Skipulk makes two styles of traces- their expedition ones have a ball joint on each end.  That is the best system, you can see the attachment for this on their site if you look at their expedition harness. This design is much better than their other one with the ring end. It is attached to the belt by a clevis bolt and a lynch pin so if you want quickly off of your pulk you just pull the pins, useful if (when) you go through the ice! With the other there is fumbling around and two hands involved.  I built the two ball joint polls myself with two  $5  internal threaded (femal) 1/2 inch ball-joints and two six-foot Sunguard 1/2" fiberglass fence posts. The advantage of these is all you have to do is thread the fiberglass rod with a die, epoxy the threads and screw on the ball joints, done.  No reducing nuts and threading sleeves, etc.. They are larger at 1/2" than the Skipulk ball joints which are 3/8", but also stronger.  You need to use a suitably sized channel to make the attachment brackets to go on the sled, and you need to make the 1/2" clevis pin/lynch pin assembly for the harness-end attachment.

I would like to post some pics but don't see that option.  

Just add snow!
