Securing Smart Car Ramps to Truck Bed (dont rely on friction alone)

Recommended Posts

Is anyone relying on friction alone to secure the ramps to their beds?  If so, I had an interesting mishap. 

Driving off in Gettysburg, PA, the bottom drivers side frame scraped the ramp off the bed!

Left front tire was hanging in mid-air (sorry I didn't have the presence of mind to snap a photo).  A couple of young men helped me lift the Smart up, while the DW slid the ramp under the wheel and back on the bed.

Drove her off and immediately drilled holes into the frame, through the ramps.  Now I insert 2" long bolts to prevent a recurrence.

Clearance has always been close but guess the angles lined up just right so the frame scraped the ramp off.

Glad you didn't end up as a you-tube video.  We have a simple arrangement which secures our ramp, as the ramp itself has a flange protruding down, which slips into a pocket on the side of the truck.  No bolts, pins, or other hardware to loose.

Friction.....where is it when you need it?

I use pins through the lip of the ramp and bed to align/secure the ramps to bed.  Glad that your episode had a happy ending.  We all live and learn as we travel along.  Continuing education....

I actually screw a bolt in the ramp now. I used simply friction first few times. When I discovered one moved backwards some on me, I changed that. Glad no one or anything hurt.

I am a :belt & suspenders" type when it comes to loading the Smart. I bolt both ramps with 2 bolts each.

Ya no don’t. Make a mechanical connection of some kind between decks and ramps especially when loading machines under their own power.

Her'Bolting down front chocks was time consuming as well as sometimes a problem with threads getting messed up.  So this is how it's done now.hLDLnG7l.jpg

Instead of bolting the chocks on the front, I use 2" ratchet strap with a hook to hook onto the truck mounted bar with the pin in it.  Less grief.

2 bolts per ramp and not an issue. Then again, every Herrin bed I have ever looked at had that arrangement and funny thing, never have heard of a car sliding the ramp off the bed....

Mine was the 2nd smart bed that Larry Herrin built. I don't "know" about the 1st one but he built mine, like you said, with 2 bolts per ramp. The man knows what he is doing. I changed the bolts out with detent pins many years ago. But in 10 years, neither ramp has moved at all.

I switched the bolts out for the detent pins 2 years ago,  The ramp foot still sits on the deck but the angle iron bolted to the foot sits in a stainless build out on the side of the deck.
