Catastrophic Failure GRIP 1000# Car Dollys

I had 3 out of 8 casters snap clean off the the new set of G.R.I.P. (Grand Rapids Industrial Products) car dollys today. I loaded up my 54 dodge on two sets. The rear end moved fine. The front where most of the weight is snapped the casters clean off their bases. They did not swivel like they should, instead they toppled over. See my journal for pics. I see no sign of a torn metal from a weld failure,, actually I don't see any sign of a weld at all on the parts. Its as if they where glued on.

I'm just glad the damn thing did not drop while I was working under there.

Anyone else had similar issues?

Some more info

Well after cooling down a bit I went and looked at the box and instructions for these. There is NO company info anywhere on the box or directions. I bought them at carlisle at the cheap tool tent. I knew the deal was to good to be true. Here's what I got looking around the web. Seems GRIP is actually

Charles Amash Imports, Inc (Grand Rapids Industrial Pdts)

4628 Amash Dr, Wayland, MI 49348-9789, United States (Map) (Add Company Info)

Phone: (616) 877-0000

Also Does Business As:Grand Rapids Industrial Pdts; Grip On Tools

Nice way to market your imported tools and make them sound American. Also nice way to avoid putting any contact info on the page.

Looks like I'll have to start with a nice letter about the false advertising on their faulty product.

I don't remember what brand I have, but I remember that the front end didn't move as easy as the rear. I've found that I had to turn the front casters with channel pliers. This is on my '55 Mercury with a stock engine.. I don't recall the capacity of my wheel dolly's. I got mine at Murray's auto, and they were made in China and look similar to yours.

Looking at your journal, I'm just going to speculate your engine might be heavier than the original. You may have been over the dolly's capacity, 4 dolly's at 1000 pounds each is 2 tons which our cars aren't that far from.

It looks like where it broke is the part of the caster that's supposed to swivel, and I don't think it's welded, more likely it's held together with some sort of rivetting or spin-over process. It's a bearing joint and the heat of welding isn't conducive to that sort of precise fit.

These things when they're at the upper range of how much weight they can handle don't turn well or anything, and any bump in the ground can catch them.

I've had to roll the front end on the jack when I get to bumps or jack up the car to slide the dolly's over a little more.

There might be ways of putting the rear dollys closer to the center of the car to transfer more weight onto them and off the front.

But I haven't broken casters off, if that was your question.

I bought a 4 pc set at Harbor Frieght 80.00 I think...used them 1x and while pushing the car the wheel edge hit a crack in the floor and the wheel folded under like a cheap lawn chair under a fat man

Now I use them to store engines and transmissions on so I can roll them around.

Next stop would be the scap metal pile

Might want to try these home made dollies (by LanceM) as a replacement. Original post (with source for casters) is here It's entry # 107.

I made some dollies about like the ones Cboy showed but since I had some casters on hand I got from a swap meet somewhere I put 8 casters per dolly on as they were a bit lighter than i liked..seems to be working just fine..

here is the thread on mine that I made. Again LanceM was a big help for me.

Home made car dolly

I thought the store bought ones were to cheaply built and too expensive for what they offered so I made my own. They are still working fine. Also there is info in my journal on entry 15 and 20

The big trick seems to be finding the HD casters at a reasonable price.

Well it is the stock engine actually a little less weight on it since it has headers instead of the stock cast intakes. I got a reply from their company stating they would email me today. The comment about folding "like a cheap lawn chair under a fat man" is awesome.

Funny thing is I built a rotisserie with these casters

http://www.harborfreight.com/cpi/cta...emnumber=38710

4 on each end and they rolled fine. no engine or frame but half as many casters . There is even a kit online to "fix" these with heavier casters.

The pan seems fine for the purpose, just the casters swivel poorly. The way they are mounted into the plate does not look like weld after all more like a riveting/pressed process. They could have worked with a little stronger steel on the mounting portion.

Looks like the casters for the homemade ones are discontinued at surplus center.

GRIP Dollies - SUBSTANDARD HARDWARE

I never got to the CATASTROPHIC FAILURE stage, because while assembling these P-O-S dollies, two of the bolt heads snapped off before being completely tightened.

If you use these WATCH OUT and for God's sake, don't ever put anything you like, like your body, custom parts, etc under the vehicle while it's on the dollies.

Needless to say... RETURNED FOR REFUND!

Off to buy GoJack's now......
