run-up blocks

[MightyThor]

You guys inspired me.  Built these over the last couple of evenings.

Interesting design.  How do they perform?

Can i borrow some ramps?
You da man, they look great. I could use a piece of rope on mine for a pull of sorts, had any thoughts there i can bor/ wait wait that has to go at the top hahahahaha

good work

[MightyThor]

Got the basics from the BCM site, they are heavy.  Will have to add rope handles and will be moving them with a handcart cause they are nearly 11 sheets of 3/4 plywood for the 4 of them.  Just a little short of 2 3/4  sheets each.  Finished last night so I haven't put the bus on them yet, but they should hold anything I can drive up on them.

Are they 9.75" high or do I need more coffee

Are they 9.75" high or do I need more coffee 

yes, 13 layers, just a hair under 10 inches and will fit under the bus with the air bags down.

I made my ramps as Tror did except mine are 12"wx48"L and the top I believe is around 18"L.Going on 14 years and still work well.

Looks like they would weigh about 150# each.  You could carry one in one hand and an 8D battery in the other for balance.

Would these ramps suffice for our buses, Eagle 1973 05, weight unknown at this time, bus was double framed on repairs.  This is just a question of inquiry to get feed back.

Literature states 16,000 lb.  I guess it all depends on the surface the ramp is on.  I've looked at these before and seems they may work but may slide as you try to drive up in it.  Worst that can happen is it would crush but seems to be well designed.

Literature says it's rated for a vehicle that's up to 16,000 lbs GVW.  That translates to 4,000 lbs. per wheel (more or less assuming all wheels on a vehicle are the same weight, which is very unlikely).   That's not enough for most buses.   

[mung]

If it crushes while you are under it, that would be pretty bad.  I wouldn't trust them.

[Lin]

It would be nice to find pre-made, relatively light ramps in the style of the ones linked.  However, I have my doubts about those.  One could always contact the manufacturer and pose the question to them.

The way I would figure it, you use two ramps to lift half the weight of the vehicle. So if the GVW was 16000#, that would mean that two ramps can hold 8000#-- or just 4000# per ramp as was mentioned above.  Two of these would almost be good enough for my front axle.  Four of them would be almost okay for my rear.  Unfortunately, almost is not enough. A set that could do 6000# a piece would be very interesting.

Nice work Thor, I would trust those for sure, Nelson

   Read the one and two star reviews for those Rhino ramps on Amazon. Be sure you read the reviews on the 16,000 pound versions.
