smart car ramps

Not sure why they say that!!!???? We have the plate end on our 12" wide, 12' long ramps from them and we have proven again and again that you can do 48" high without any problems. And there are plenty of fixes if you have any kind of problem at all. These are the Smart Car Trailer Ramps.

 

At the Rally we even unloaded a car using the 1/8th inch angle piece between the hinge area and it raised the car off the edge of the bed by a good 1/2 inch.

 

Like Carl said, the breakover angle is all you're concerned with, and adding 2 x 6's or 2 x 12' at the bottom takes care of that. Now don't mistake our statements - you should be loading at level ground to your truck, or even higher. My drop off this am was more like 12 inches, so I moved the truck to more suitable unloading area (like a parking lot) and unloaded quickly.

That 12 degree angle flattens with the full weight of the Smart on it but returns as the wheels load over the top onto the bed. With an Air suspension on the truck, don't forget to deflate it before you load. That lowers the bed height about 4".

 

One caution is when coming off forward; The battery box under the passenger foot area may hit if the angle to the ground is too steep. Just be aware of this and you can plan for it if necessary.

We have a 47" deck and also use the Big Boy 19" wide ramps that Phil referenced. They work just fine . . . though we did make an "improvement".

 

Our first load was not on level ground so it was probably closer to 50" inches and we rubbed the smart belly. To give more clearance, I removed the top splined rod (like the ones in the picture) and we cleared fine after that mod. The top rod is right on top of the landing plate and really doesn't contribute much to the stability of four rectangular aluminum tubes. It may contribute to tire traction if you drive up. We winch up so I wasn't concerned with any tire slippage that may result and I'm comfortable we had no loss of capacity with that change.

 

We also took Roger's advice and have a couple bed frame angles cut to 19" that we can place at the hinge which decreases the break over angle and gives us another 1/2" clearance that Rocky noted.

I guess I've been pretty lucky. I have a 47.5" high bed with air in the truck. I have no issues hitting and I do not dump the air. If I am on ground LOWER than the plane of the truck I do come close, though. So like others I try to find locations that are at least the height of the truck.

Re the pcs of angle iron, I made up 3. One as a spare. The saying goes something like 1 is 0, 2 is 1..you get the idea. Mine were painted Fluorescent red, the same color surveyors use.

The 1/8" angle raises my ramps 1 1/4" in the hinge area. The nose does get a little closer to the ground.

You can cure the "nose closer to ground" problem, with a couple of 2X12s. My ramp set-up worked great with the '05 smart, but the front valance on the '11 is lower and hit the ground going on or coming off the ramps.

 

I took two pieces 2 feet long and two pieces 1 foot long; beveled the ends and screwed them together. Put them under the ends of the ramps and that raised the bottom of the ramps by 3-1/2"; in addition the front wheels level out for a foot and a half before reaching the ground. to store them I just slip the "supplemental" ramps into the folded aluminum ramps before I slide them into the storage below the deck.

I suppose I'll have all these issues one day. But my current bed/ramp/smart never seems to hit anything....I guess I'm lucky. I also have NEVER dumped my air.

 

I AM somewhat careful on where I load/unload, and try to make sure my ramp ends are at least at the same level as the truck.

We use the 12" ramps and have never had a problem. We clear the break-over by 3-4 inches with standard ramps and usually don't dump the rear air. LOL. The first time we unloaded, I dumped the air but turned off the ignition. After the unload was complete, I looked at the rear and noticed that it was level! Hmmm....shouldn't it look lower into the wheel well?!? I then learned that my Volvo will re-inflate if I don't leave it running or at least leave the key turned "On" in the ignition!

 

We have no problems with our Smart either way....and I drive it off, winch it up.

Whats Next, you can also dump your air tanks via the drain valve lanyards to keep the truck squatted.....just another method to the same end as leaving the switch on. Occasionally, I want to stay hooked up and can level the 5er by fully or partially dumping the air tanks by using the drain lanyard so that I don't have to leave the switch on for an extended time. You will still need to use the switch to dump the rear bags but the lack of air will keep them from reinflating when the switch is turned off. Charlie

When I lock the switch down, the bags stay down but once I am parked I inflate them and put a crutch under the frame to keep them from sitting completely squashed for a long time just to reduce the stress on them. Before I built the bed it was more convenient to put a 2x4 on edge under the axle stops to keep them partially extended. The bed just makes that impractical, now.

 

The first time I loaded (video is on my blog ) I was worst case. The foot of the ramps were below the plane of the truck wheels and I forgot to blow the air bags. My first attempt hungup on the top rung of the ramps at the edge of the smart frame just behind the front wheels. Mostly because of the lower gap that was left between the ends of the cat walk section and the edge of the bed. 881797024_hdsbpTh1_thumb_thumb.jpg?imgma I also sunk these gripper sections of the old catwalk into the bed but the top edge of the ramps was on top of the bed and actually a couple of inches higher than the sunken part where the wheels would come off of the ramps. I dropped in a short 2x 6 in that that gap and everything went just right. The gap left a place to drop in HDT rubber chocks on the opposite side to act as stop chocks when loading and unloading. This design makes the bed ambidextrous.872902887_5bJJgTh1_thumb_thumb.jpg?imgma871837162_MAVebTh1_thumb_thumb.jpg?imgma

 

Whenever possible, I try to load a bit more horizontally. This is my usual spot at the house.
