i think these things are junk! after only a few uses the cheezy rubber pads they put on there to keep them from sliding just fall out.
i trailered my car out to the track saturday but didn't have my ramp extentions to get it off. as low as the car is, it catches on the rear rail of the trailer without ramp extentions. since i didn't have them with me, i figured, "what the hell, i'll just put the short ramps on the rhinos and roll it off that way."
well, it almost worked. except a tire kept hitting the trailer fender and prevented the car from rolling off cleanly. so i go into reverse to pull the car off the trailer but the wheel instantly spins the rhino ramp 30' forward and drops the car frame on the trailer. while a wheel was still on the short ramps, which now were all the ramp i had, i attempted to pull it back up on the trailer and shot the other ramp 30' behind me! i did get the car unloaded eventually but still had a hell of a time.
this is a rather common problem i have with these stupid things. every time i try to put any vehicle on them, they push out of the way or slid out from under the car once it's half way up. i have finally figured out that the only way i can use these things is to take a rubber floor mat and put it under the ramps so it grips.
with all the used tires out there, you'd think rhino could cut a few up and make decent rubber pads to keep them from sliding.

 

I agree about the useless rubber pads. The rubber floormat trick works. Unfortunately, the Rhino Ramps don't lift high enough for my needs.

I built these based on Mike Mercury's design:





10"+ of lift and they ain't about to slide nowhere...

For the "naysayer's" about to pipe in re: safety, I'll be posting pics soon of my F350 diesel dually (8500lbs. GVW) parked on these...

 

My cheapo ramps I got at like autozone never slide... They don't even have rubber things underneath and they can be broken down in to 3 pieces.

 

Where did you get the design for these? I'd like to see those and maybe build a pair of my own, and definately see the 350 parked on em.

 

Just emailed you for the design.

 

The plans are from forum member Mike Mercury. Do a search for his name and you'll find 'em.

I added additional bracing and metal strapping to prevent the sides from bowing out and failing. I also used construction adhesive in addition to coated deck screws.

 

That's why I only run my front wheels on the Rhino ramps......I also use a rubber door mat under them,cause I use them on the up slope/down slope of the driveway....

 

Don't you guys in El Cajon just run two wheels up on the curb to work on your cars?

Nice Ramps Tony

 

Thanks, but all the credit goes to Mike Mercury for the design. The only downside is the weight. Not very portable if you have to take 'em outside the shop. I might make the next set out of balsa wood...

 

I have a set of ramps that I hardly us because the like to slide out while driving up on them. I just wedge a 2x4 between them and my garage wall to keep them from walking. The only thing I really use them for is oil changes.

 

My Rhino Ramps work just fine...all I do is simply stick a piece of carpet/rug under them and they don't slide whatsoever. I suppose the rubber pads could have been better engineered, if you will, but I never took a chance with them...

 

I have a set of steel ramps and they never slide... but that could be because my concrete garage floor is so pitted!! If it was smooth concrete they might slide.

 

Cool, just printed it out

 

This is what I use..... Ultra Ramp......I don't think I'd trust anything I made of wood to support my car.

The extensions prevent the ramp from kicking back or sliding forward.

 

 

I guarantee yours would collapse before those wooden ones.

 

Really? I'll take my chances....
