Question Weight capacity of homemade ramps made out of 2X10 lumber

Hello,

Anyone has any thoughts regarding how heavy a vehicle could homemade ramps, made out of 2X10 lumber safely support? These ramps would have a 4 foot base with 4 layers of 2X10 yellow pine, each layer 6 inches shorter than the one below it. Each layer would be attached to the layer below it with 3 inch screws.

Thanks.

If you are speaking of a design where you stack wood one piece laying flat upon another then you should really have no problems unless you are running a tank or something like that over it. Many guys have made them like that, including my dad. In fact, you could even get away with 2 x 8" wood for that. Good luck.

how are you going to attach them w/ 3" screws that will come out the other end once you sink the screw head in a bit. go 2.5" screws

I can't imagine you'd have any problem with any vehicle.

Lots. I used that setup to level my 6000lb. Dodge Maxivan when camping. The nails fit into predrilled holes so I could go up in increments.

I stack 3 high loose, one each 4 ft, 3 ft and 2 ft long 2x10 every time I change the oil in my F-150. I think it's fine....but if you plan to use over and over I'd go with some pressure treated boards and maybe just drill holes and use a length of rebar or other rod the whole way through so you can break it down to carry easier. Even some 1/2 copper pipe dropped through slightly larger holes would keep them aligned good enough.

We have driven a 14,000 pound truck on a set of ramps like you describe, no problems.

Had this arrangement for years. Put it together with screws and wood glue and cut a taper on the front edge of each layer so I could drive up on it. It is all solid wood, you probably could drive a tank up on it.

Wouldn't it be easier and lighter to use 1/4 angle iron on both sides of a single 2x10?
I use 2x8's, but support them with a set of car ramps when loading something heavy.

Are you talking about ramps that you'd use for loading something on a trailer or back of a pickup, or ramps that go on the ground to raise the front or rear of a vehicle?

My trailer ramps hold 12000lbs fine, they are 2x3" 1/4" thick C channel sides with 2" 1/4" thick angle iron rungs. They are about 7ft long though.

Thanks guys. A plan to use 2 sets of these ramps to raise the cars to work underneath. I thought they would be quite sturdy but just wanted to get some expert opinins.
Thanks.

I've used stacked 2x12s for years on cars, SUVs, tractors. I cut a 45 degree angle and leave just enough room for a tire patch on each layer. I screw them together with 2.5" screws facing down and attach a tire stop to the far end. To get all four wheels up, I usually just jack the rear up and slide a short 'ramp' under the wheels.

If they are stacked, and assuming no span, any vehicle with inflated tires that fit on the boards should not be able to crush the boards. I would worry more about racking if it gets too high.

Heck, the dozer on the family ranch rides on pallet wood to cross roads and only beats the wood up minimally.

Wood is very strong in compression.

So the ramp you are making will only raise the vehicle 6"? Keep in mind a 2x is only 1.5" thick, so with 4 layers you'd end up with 6".

Also, how wide are your tires? A 2x10 doesn't give much leeway when driving up them. The tires on my truck have 10" tread so if I'd get slightly off track I'd risk tipping the ramps. I suggest wider ramps if possible

My guess is that even the tank would be OK. When we put chains on our fire engines for heavy snowfalls, we drive the inner rear wheels up on solid blocks of wood, cut at a 45 on one end. Been doing this for 20 years without a hitch. These trucks weigh about 55,000 lbs. for the lightest one.
