Wood boards as a backup for Rhino ramps—how high?

Wood boards as a backup for Rhino ramps—how high? - 03/17/18 03:01 PM

I have a pair of 16,000 lb Rhino ramps I drive my cars up when I change the oil. Because of stories of ramps and jacks failing, I like to use a stack of boards that I have in my garage, as a backup plan. I put them in between the two tires on each side.

My question is—is there a given height that my stack of boards should go? Do I simply have to put my stacks high enough to allow me to have room, below the level of the boards, if the chassis falls? Or could the innards at the bottom of the car, drop lower than the frame itself, that is resting on the boards—in which case, I’d need to give myself a few extra inches of leeway here.

How high do you want? Each board is about 1.5 inches thick. So for whatever hight you need you can calculate from there. I put in four layers. It got my Versa up 6 inches. Perfect for my oil change on the Versa. Need higher? Add layers but know that wood can be heavy so you are adding weight as you add on height.

I’d recommend the full height to the chassis and tight against the chassis. May I recommend to pick up a set of jack stands on sale. They are are much easier to work with. (But rememeber to pull them out at the end of the job. )

Regular price is over 100 bucks. Is this a reputable company? WM has them for $24. 3 ton capacity would cover the Sienna as well.

Alternately, PB has this set: https://www.pepboys.com/product/details/1154551/00773?quantity=1

Harbor Freight: https://www.harborfreight.com/3-Ton-Steel-Jack-Stands-61196.html

Not sure which companies can be trusted here. Rather not use chinesium as my backup plan.

$100 is [censored] wishful thinking, marketing. Those are around $25 anywhere you go.

There, I fixed that for you.

I'll vouch for these (That all pretty much come from china, no matter who sells them)

The ratings are utterly ridiculous - 3 tons (6,000 lbs) is wishful thinking at best.

Used properly in general auto use, they are just fine.

I like to place a 12" x 12" square of 3/4" plywood under each one
when used on any surface other than concrete.

My grandfather built something similar to these about 50 years ago.

They are nearly indestructible & will hold a semi-truck!

If you are worried about the ramps failing make some of the pine-o ramps. That is what we used when servicing semi's.

I see why he has wheels … mine are heavy enough that I put a gate handle on the end

Purchase 2, 2"x 10" x 12' boards. One board will make a ramp. Lowes will cut to lengths shown. Get some nails, or screws and adhesive. Cheap. simple, and heavy. I have used them for 8 years.

One nice thing about these is they will not slide away when bringing a RWD vehicle up on them … the first 1-1/2” rise pins them down tight
Pine-O Ramps have their place …

I use the harbor freight jack stands when I need to use jack stands.

If wood is capable of holding up the car as the primary support, it should also be ok as a backup support, shouldn't it?

If possible, I'd like to get more input on my original question--assuming I'll continue using wood boards, how high do the boards have to get? Snagglefoot said take the boards up to the height of the chassis. Is that what is best or what everyone does, who uses boards?

My ramps are a stack of 2 x 12s. For safety I throw a short log or two under the car and chock a wheel. It's not worth taking short cuts when it comes to safety.

As long as you don't have them stacked haphazardly so that when the car comes down haphazardly, the wood doesn't come tumbling down and the car is sitting on your head. The proper way would be NO space between the car and secondary support so that there is no chance for things to teeter-totter, etc.. Of course the wood has to be higher than the height of your head, chest, etc..

Only you can decide how safe you want to be. I choose to use the proper tool: jack stands.

So the concern with wood boards is that they will be unstable? If in fact the rhino ramps are failing, I can see how a car might push a board off a pile if the car isn't falling straight down... Interesting.

If you are interested in improving safety, use jack stands. They are relatively inexpensive and they are easy to store. Get ratcheting jack stands so you can fine-tune the height.

Has anyone ever put a rhino ramp on a 2X10 with a back stop to get that extra 1"+ we often look for?

They had a set of nice jack stands on Sears the other day for $17 and change each.

+1 on Sears jack stands. I picked up 3 sets over time because of rolling points and great deal. Cheap gifts! Also inspect the welds, they do occasionally have defects.

A coworker of mine swears by phone books to back up his ramp.

A concrete building block serves as my safety.

Kind of like the phone book tactic. Probably could use any large books, like dictionaries or encyclopedias stacked up to the frame. If the ramp collapsed, the books would not damage the frame when it dropped.

I wouldn't use ramps and jack stands together since the suspension will push the ramps out as the weight increases on them. That would cause a stand failure for sure. One or the other IMO, but wheel chocks for both methods would be a good idea.

There was a nice jack stand/ stool thing on here a while back where a pad sat on the jack and was lowered onto the stool with the car on it. Seemed like a clean and simple design, but last I looked they were on back order. No lifting the car by non approved jack points to get stands under it.

This is pretty much how mine look. I have steel ramps but they don't fit well on my Versa. The wood ramps do perfect on the Versa.

Great find! And they are 4 ton jack stands.

I'm wondering if there is any downside to the stands Johnny Johnson linked to (http://www.kmart.com/craftsman-professio...720_59415_Tools).

The reviewers avg. 4.5 stars. Verified purchased reviews have almost all 5 star reviews. They are on sale for smae price, with the same reviews, at sears.com also.

Does anyone here think these might not be good enough? They are 4 tons (both jacks); my minivan is only 5700 lbs so I should be good there.

A Sienna? Not unless you have at least 1300 lbs of cargo in it (or 7 adults and a full tank of gas).

Re: Wood boards as a backup for Rhino ramps—how high? - 03/19/18 11:48 PM

Edmunds has the curb weight at 4120, and gross at 5690.

Since I don't plan on changing oil with 7 passengers inside the van, I can plan on using the curb weight as the figure I want, when buying jack stands.

Must have confused the two numbers.

I dug a pit large enough to finish with concrete walls and floor (lot's of rebar in Italian butterfly style) I did however dig using a chinese made shove and the plans were printed on a chinese made printer. Am I taking my life into my own hands when using this pit?
