Superclamp Rear - Install

Recommended Posts

Just got a superclamp rear for my Trailer.  The trailer is a Triton Elite.  Has anyone installed one of these on a similar trailer?  If so did you just sandwich a piece of aluminum plate under the wooden PT trailer deck for support.  Or did you weld something under the deck to attach to?

The washer that comes with the clamp is enough to hold it , the piece of aluminum you are talking about ( 2"x2")would be better and all you would need .

I have 2 which have never been installed. If I do someday, then a plate of some sort underneath will be installed for sure.

Yeah it came with supertrac.  So no washers.  Just 3 machine head screws with a nylock nut and a couple wood screws.  I'm thinking a 1/4" aluminum plate at a minimum.  Maybe I don't have as much faith in plywood as some.

I installed both front and rear about 3 years ago on a 10yr old enclosed trailer. Did the same as others, grabbed a piece of scrap steel laying around and cut it to about 3"x3" for the front and similar for the back ones. Sure wont be pulling through! There is a lot of pressure being put on them and I wouldnt personally trust a washer.

You guys really find the need for the rear one, the front one does such a great job.

I throw a strap on the rear, but only if when I thinking or concerned about being possibly pulled over by the police.

Otherwise, the rear of the sleds in my trailer never move.

I used to do the same until I hit some black ice. The truck and trailer started snaking down the highway. We pulled out of it. The fronts held in place. The rears of the sleds swung side to side banged and damaged the walls of the trailer. Insurance wrote it off.

I think you need anchors at three separate points? Anywhoo, I think it was sledjunk told us a story about a guy whose enclosed trailer ended up upside down in a ditch after an accident - opened the trailer door and the sleds, fastened with front and rear superclamps, were hanging upside down perfectly without any damage or coming loose of their moorings.

I guess both skis and the rear would give you the three points.....which I would still have, most days with the rear strap in place

 

The crazy accident scenario would be a place that I can see the need for sure, that makes total sense....and that story sure would be a funny one, given the situation.

I think Livin' can laugh now but he wasn't then.

Yeah I was wondering about tie down requirements to be legal.  Definately need a rear tie down.  But is three points sufficient which is essentially what you get with super clamps front and rear. I'd heard rumor that you are supposed to have 4 points?  I'm confident my new three point system is safe, but is it legal?

(ii) are strong enough and high enough to ensure that the load will not shift on or fall from the vehicle, and

(iii) have no opening large enough to permit any of the load to pass through;

(b) at least one tiedown that meets the requirements of subsection 2 (1) for each 3.04 linear metres of lading or fraction thereof, and as many additional tiedowns that meet the requirements of subsection 2 (1) as are necessary to secure each part of the load, either by direct contact between the load and the tiedown or by contact between the load and dunnage; or

(c) any other means that prevents a load from shifting or falling that is similar to and at least as effective as the means specified in clause (a) or (b). O. Reg. 363/04, s. 5 (1).

(2) A tiedown or dunnage in contact with exterior, topmost items of a load and securely holding each interior and lower item shall be deemed to comply with the requirements for contact in clause (1) (b). O. Reg. 363/04, s. 5 (2).

(3) If the load may shift in transit, the load must be blocked, restrained or contained in such a manner that it will not shift in a forward direction when the vehicle decelerates at a rate of six metres per second per second or more and must be,

(a) the active portion has knots in it;

(b) any component of it exhibits stretch, deformation, wear or damage beyond the limits specified by the manufacturer; or

(c) it has been repaired or shortened other than in accordance with the manufacturer’s specifications. O. Reg. 363/04, s. 6 (4).

I'll chime in on the backing plate. Put a plate behind the plywood. I had a brain cramp a few years ago when unloading the Ranger. Unfastened 3 of the 4 ratchet straps. Backed off the trailer & pulled the D ring the remaining strap was attached to, off the deck of the trailer. All it had was 2 nuts & washers as backers.
