Title: Quality tie downs
Post by: Gliderjohn on January 27, 2018, 11:25:38 AM
Getting tired of screwing around with the typical hardware store ratchet type of tie downs. Any recommendations for quality tie downs. Talking tie downs for strapping a bike or ATV in a PU bed or trailer.

Ankra.  Do NOT buy anything with text either silk screened or  embroidered into it...............do n't ask how I know.

Well, never mind I will tell you.  I have a 6x12 enclosed trailer I was hauling my Cali Touring in last fall.  The tie downs had some advertising from wherever I bought them from silk screened onto them.  The Cali tried to escape through the side door, as the clasp slid on the silk screening!  The trailer was more damaged that the bike, but never again for me.  I like to use the "soft" style straps and I usually use a carabiner to secure it to the D rings.

    Ancra, Ancra or Ancra.  Little more money but well worth it. I still have two pair I bought in the 70's and still work as they should.

Get ratcheting tighteners...not the cam-lock type. Look for at least 1 1/2” width on stiff webbing. Store them clean in a dry, dark storage place. Replace when recommended by the manufacturer or when the webbing becomes damaged.

Yep, yep yep!!!!!!  ANCRA is the good stuff.

If you want ratchet tie downs then stay away from the 1" strap tie downs. Most are way too flimsy.  Go at least 1-1/2" or 2" straps and look at the ratchets.  The thicker the metal, the better the tie down.

Don't leave them out in the weather any more than necessary as most straps will photo-degrade when left in the sun for long periods of time.

Canyon dancer strap for the front...best solution.

For the rears, normal tie downs...

2nd the mention of Rokstraps for gear on the bike...simply the best  and most elegant solution.

Reese, the hitch people have a really sweet self-retracting strap.  I've only been using them for ~1.5 yrs. but they take much pain out of messin' w. non-retractable straps. Fast and dumb easy to store.
I've used Reese hitches on every tow application w. cars and light trucks. Excellent equipment. 

I will not use Canyon Dancers on bikes with cast metal handle bar mounts. Those castings were not made for the loads encountered while towing. Perhaps not on clip-ons, either. R3~

Well...interesting feedback.  Haven�t experienced any of these issues towing for thousands of miles on the Norge yet...but will keep an eye on the items cited.  Thanks!

I figure if Mike at MPH recommended them to me many years ago, and he knows more about the motorcycle business than anyone I know...they must be just fine.  So far so good.

most big-box store or auto store tie-downs are garbage.  I've gone thru quite a few.  When I almost lost a bike about ten years ago (tie down failed) I went out and bought the best tie-down kit I could find:

http://powertye.com/store/index.php?dispatch=products.view&product_id=2

'not cheap but they are WAY better made than most and in the 10 years I've used them on everything from multiple bikes to snowmobiles to tractors they have never given me any trouble,ever.
Tie-downs are a tool, and like most tools cheaper to buy is rarely cheaper to own, 'just saying.

I have actually had flawless results when using dacron line with a trucker's hitch. Most people these days play dumb whenever faced with knots. But, you know what, simple aborigines do it with coir, so it can't be rocket surgery. All's you need to bend a trucker's hitch is a bowline. Any boy scout knows that. A single 3/8" dacron twisted rope can lift your entire truck. A braided 3/8" can lift several trucks. Doesn't catch your finger & pinch it. Doesn't scratch anything. This I'm telling you is true and easy. And unlike a ratcheting shipping strap, you keep a coil or two of rope around, you can do a world of other things round the house too.

Just don't use polypropylene. Goes all to hell quick and breaks.

The 2" powertye straps look pretty good.  Notice that some of their straps have built in soft ties.  Most straps have an 'S' hook end that can easily come apart when the suspension of your bike gets compressed.   Suddenly the whole strap is flapping even though the rachet (or cam) is working perfectly.  The Powertye has a cam to keep the hook from coming loose.  I like that!  As for the truckers hitch, I agree that it's both low tech and effective.  Beware of nylon on either straps or rope because, when wet, they can stretch 20%.   I'm also a big fan of 2" straps.  You do not need the extra strength when tying down a motorcycle.  You do need the extra abrasion resistance.  Any fabric strap will tend to abrade when you take it across a metal part.  If you only have 1" of strap and it wears through 1/2" you are screwed.  This can easily happen on a 500 mile trip and you may never see the problem until it is too late.  The same wear on a 2" strap is just "oh shit".

+1 on Powertye. I have a bunch of them and they’re excellent. I can drive hundreds of miles with a bike strapped down and they don’t loosen even the tiniest bit. I have the kind with built in fuzzy loops and have never had any type of damage to the finish. American made and excellent quality.

 :1: :1: :1: As  a licenced arborists for 40 years I can tell you first hand, knots are a far better solution when your life or motorcycle depends on it. Rachet straps may have their place but the right line with the right knot you can take to the bank.
Eliminating the mechanical aspect of a tie down also eliminates the possibility of failure on several levels.

I borrowed a friend's enclosed trailer to haul a bike one time.  He had a wheel chock in it and already had straps so I decided to make use of them.  I decided to strap the bike down and take it for a test haul before heading out on the trip.  Glad I did.  The straps loosened within 10 miles but not enough for the bike to touch anything.

I through them in the nose of the trailer and grabbed my ratcheting straps that were overkill for the job.  No issues during the entire trip.  I gave him a set as a thank you for using the trailer.

Title: Re: Quality tie downs
Post by: Tom H on January 29, 2018, 01:27:09 AM
Interesting reading. I agree that all tie downs are not created equal. But...

I have been using no name 1"ish ratcheting tie downs and a few1"ish cam style straps for over 25 years to tie down everything in my '62 F100 bed from boxes to bikes. Some straps are that old and still working.

I have had some brands of ratchet straps that are junky, they don't release easily or the like, but I have never had one fail when properly used and not exceeding their weight limit.

I have loaded and tied up my Eldo and Ambo in the back of this truck with a 6' bed with 4 ratchets and two cam style straps. Drove 40 miles down a mountain road and then 60 miles of freeway without an issue.

Ratchet straps when used on cardboard boxes can get loose as the box crushes. Well that's why you should check your straps. But with the bikes, I check them once in the first about 10 miles and then just about forget about them. I do check them every time I need to stop though just for peace of mind.

If you use a ratchet style strap properly, you do not wind the excess strap on to the ratchet. Properly used you would have one hook on the bike and one hook on the truck bed. Then with your hand pull the tag end of the strap tight when threaded through the ratchet. Once the strap is hand tight, then start using the ratchet to fully tighten the load. It only requires one or two full turns of the ratchet to lock the strap. More turns may be needed to pull the load tight.

FYI: In a former job, I have used rope, ratchet straps and the welded on bed ratchets to secure loads on trucks raging from pickups with stake beds to 40' trailers. Mostly pallet racking and 4X8 particle board and then had pallets of misc. matl. on top. This was done with the appropriate sized strap for the load, 3-4" strap.

To sum it up, get the right rope/ strap that is appropriate for the load and all should go great.

Just my 2 cents,
Tom

Rope.  It fits anything if you know the right knots.

The right rope, and the right knots.  When I used to work with scouts I would ask them what the difference is between using the correct knot for the situation and using the incorrect knot?  The correct knot can be untied.  When using a rope to tie down something I always put a loop in the rope so I can half the force required to cinch down the load before tying it off.

I've got a set of Ancras from the 70s and they're still the best I've got. Twenty years ago I bought a batch of no-name tie-downs from the Honda shop for hauling seven or eight bikes from Los Angeles home. Like any cheap tool, they're not the most pleasant to use, but so far they've held up. You definitely get what you pay for, but they did get the bikes home safely. Whenever I haul a bike now, I've got so many tie downs, I double them up. I also tie the loose ends in such a way that if the clamp opens or loosens, it can't loose much tension. I also tie down the back of the bike as well as the front - overkill in that department is just about right as far as I'm concerned!

Agreed on the rope! It was an ah-hah! moment when I realized the purpose of hitches and knots. I recall towing a car with rope before I knew that, and was never able to undo the knot afterwards. Proper hitches and knots also reduce strain on the rope.

I'm all for that, but when I look at the specs for "braided 3/8" Dacron line", I find that the working tensile limit is 375 pounds ... ?   Even allowing for a safety margin, that's not one truck, much less several ... ?

No more cursing at twisted-up webbing in a ratchet strap, or trying to undo one where someone wound two feet of web on the spool.   No more bungee cords trying to hold gas cans in the back of the truck.   No more "this strap isn't long enough".

Just two or three 20' lengths of braided rope coiled neatly behind the seat and I'm ready for anything ... the trucker's hitch ....

On top of all of that (100% accurate) they look good too...picked up two pairs of Orange and Black ones last year at John Day National at wholesale prices from the guy selling (Rolf was his name?? ...can't remember)...a pair of thick/wide ones and a pair of narrower ones...brilliant design, just brilliant I say!

The thing I really like is once tightened,  the elastic keeps tension on the load, and you don't have to cinch them down again 50 miles down the road.

The entire language of knots is comprised of just three letters -- IOU:
(http://laterdudette.com/images/IOU.jpg)

Left to right, the standing part, the overhand, and the bight. That's it. Three things. All you got. How simple is that?

To bend a trucker's hitch, you loop an overhand into it and then grab yourself a bight:
(http://laterdudette.com/images/bowline1.jpg)

Now tie a bowline with the bight ... rabbit goes up the hole, round the tree, and back down the hole:
(http://laterdudette.com/images/bowline2.jpg)

Your bitter end is the part you pull on. Send your bitter end thru your tie down, then up thru your bowline you just tied. Here, the carabiner represents your tie down:
(http://laterdudette.com/images/truckershitch.jpg)

That's your trucker's hitch. Essentially, you have made block & tackle out of your rope. It multiplies your force, cause you have to pull your bitter end two inches for every inch you move the standing part. Two to one. You could easily send your bitter end back thru the carabiner again, then up thru the bowline again, and now you'd have multiplied your force four to one.

Your standard three strand dacron rope has a breaking strength of 3500 lbs. With a ten to one safety factor, that's how come they tell you 350 lbs. But you are not breaking the damn thing by pulling a ton. So, yeah, pick up your truck with it. A hard braided 3/8 dacron rope, like what they call bull rope, your breaking strength is gonna be five K.  So "several trucks" is hyperbole, I admit. But here's the bottom line: With a 3/8" rope on each corner, your bike is not going anywheres. Period. If you don't believe me, go wrap a bit of that braided salt water fishing line round each fist and try and break it. Be sure to wear gloves.

But you are not breaking the damn thing by pulling a ton. So, yeah, pick up your truck with it. A hard braided 3/8 dacron rope, like what they call bull rope, your breaking strength is gonna be five K.  So "several trucks" is hyperbole, I admit. But here's the bottom line: With a 3/8" rope on each corner, your bike is not going anywheres. Period. If you don't believe me, go wrap a bit of that braided salt water fishing line round each fist and try and break it. Be sure to wear gloves.

Good info.   I would have guessed a two or three to one safety factor, not ten to one.

Been researching some knots, and realizing that different knots have different strength factors (50%, 60% (like a bowline), 80% etc).   

First I've got to get good at the simple ones ... !!
