Rolling with my 7

[DeanG]

I tried an experiment substituting inexpensive movers dollies for expensive car jacks. It seem to work OK with a light car. I am putting less than 300 lbs on each one. At $9 each they are much cheaper but a little more trouble (you have to jack up the car then set it down on the dolly) than the $75 gojack.

 

Remember, be careful, just because I am getting away with it doesn't mean that you will too.

Yup, those will work perfectly fine. They look like the $9 ones from Harbor Freight, right?

 

I think those say up to 900 lbs. So, they'll work even for my car.

 

I've had my drivetrain on one before at 700 lbs with no problem.

I'm willing to bet the 900 lbs is a bending load. When placing the wheels like that, there's quite a bit of shear load that the dolleys weren't intended for. I'd be a little more careful on your car mazda. The good side of things are you're not likely to do much damage if one does break.

yeah, I wouldn't lay under the car if it's on those, and the surface has to be perfectly smooth, like a concrete garage floor. I actually had my car on them (just 2 wheels) when I was skinning the car and rolled it around the garage very easily. As you said, if it collapses, the car falls 3 inches.

Where did you get them for only $9 each?

Harbor Freight

Harbor Freight it is. The shear question does give me pause. Through bolting may be the wisest approach.

Hi All,

 

I have been following this thread and like the idea of cheap wheel creapers but here is are what I have and use all the time and they will carry a 1000lbs each so just about any normal car dose not over load these and they are on sale at Harbor Freight. Normaly these are two for $75 which is what I paid several years ago and they are worth it as they are very robust.

Hope this helps and maybe you can get Mrs Santa to put it under your Xmass tree or what every you do for the holidays.

If you were a little worried about it, you could bolt one more board to the top on either side parallel to the car, which would then put all of the bolts in double shear (since the tire is tending to spread the front and back boards away from each other, but either way it looks pretty robust (I do stress analysis for a living). The inboard/outboard boards (say that 3 times really fast) are in little bending as the reaction from the tire is right next to where the board is being supported; I’d get under it.
