Mac's Smart Car Tie Down System


bmzero

Recommended Posts

I reached out to Mac's (http://www.macscustomtiedowns.com/) to come up with a system that will allow me to secure the Smart car or Polaris RZR on the back of the Volvo. I hope that both vehicles will be able to use the same tire baskets. For the Smart car, I will probably end up using an idler for each basket. I'm a big fan of the idlers for low clearance vehicles.

 

Since the track width of the RZR and Smart car are similar, I will be able to use two rows of their VersaTie track, one under each side of the vehicle. That will give me some flexibility to haul different vehicles (quads, street bikes, etc.) and have tie down points in just the right place.

Idler in use. On my setup, the ratchet will be on the inside (under the doors of the car), not the outside like this setup.

Do you guys have any other suggestions?

I discovered in investigating the same thing that the track was not rated high enough for my use....I forget what the rating was now, but I went with an alternative because off that.

 

In fact, even E track is not really rated that high....although it is used in auto movers and race trailers extensively.

Ok Bmzero I'm depending on you for this one you're the Internet king.

I agree with Jack the track you're looking at is not rated high enough and I have a lot of experience with E- track it will be fine for your razor but not a smart car. Also E- track collects a lot of dirt and Debris on the underside between it iand your deck extremely hard to clean out.

 

I want to know where you get the tracking they use in aircraft like a C-130. It's similar to what you're looking at but five times stronger and larger. I really want to change the system I have for tying down my rhino and my bronco when it's on the deck.

You're the man :) counting on you figure out what it is ? And where we can get it at a reasonable price.

No pressure there...

We have tied down pickups and suv's with alloy wheels by running a sufficiently rated strap through the wheel spokes at about 8 o'clock on the front and 4:30 o'clock on the rear wheels. We use a cloth softener so the strap cannot chafe the wheel finish.

"Are we there yet?" asked no motorcycle rider, ever.

We did the same hauling the smart in our toy hauler. Car stayed put up the Alaska highway. Can't say the same for a folding chair that got against the front bumper........ :(

Looked at the aircraft track system...pretty cool. The best part though was the description. Ya gotta love engineers; they make up words that sound more technical. i.e. "used in the securement of cargo" rather than "used to secure cargo" Even the spell checker says "What??"

That is what I am using to tie down my smart. The track is called "L Track" and is rated higher than "E Track". It's the same tie down system we use on 747s. I just figured if it's good enough for a 747 freighter, it's good enough for a Volvo and a smart.

There are references to lots of these parts in my "Smartcar Hauler Parts" little article on the things I looked at for my build. L track is in there, and I have used it for many things.

I like the look of the angled L- track. But still don't think I would trust it for a car.

 

Mac's VersaTie Series 2 system (similar in design to generic L-Track, but machined in house at Mac's) is rated at 10,800lb for a direct pull. Each double ring stud is rated at 5k, so each corner of the car carries a 10k rating (two double-stud rings per tire). The key here is the attachment points. Mac's pre-drill's their VersaTie for 4" or 6" connection points (based on series). The rating assumes adequate steel backing. I will be using .025" steel (technically, it's .0243, but who's counting).

 

I have chosen to go with Mac's because I have seen their systems used by quite a few of my friends that haul significantly heavier (and more expensive) vehicles all over the country for competition events and car shows. I'm betting on their product being better because they control the quality using American made extrusions and in-house machining.

 

What is the military using?? I haven't looked in years but I thought it was like the L track but much heavier.

 

Mac's has four different styles of VersaTie (L-Track). They vary in their profile and weight rating.

 

You can see the different styles at - http://www.macscustomtiedowns.com/product/versatie-aluminum-track-series2-96/VersaTie

 

Series 1 (ie. standard L-Track, which is probably what you saw Bronco)

Series 2 (my choice). You can see the difference in the extrusion, resulting in the higher load rating, even with slightly lower profile (series 2 - .430" tall, series 1 - .435" tall).

Here's the load rating comparison chart.

After making the final decision on the Series 2 VersaTie track system, I can add it to the bed drawing. The blue components are the VersaTie tracks. They are inset slightly below the bed surface. That will allow cargo to slide easily. The spacer is added above the custom C-channel to align the two bed plates with the 2x4 steel tubing. The spacer will be spot welded to the C-channel, hence the reason for the gap between the VersaTie track and the spacer. The bed surface plates will be bolted to the joists with countersunk bolts.

Having the track below the surface of the bed will also allow me to use the Mac's threaded studs to mount my fork clamps for the motorcycles directly above the track.

I used the EXACT same method for strapping down race cars in my stacker trailer. Only I used E-Track instead.......Worked awesome.
