Rolling compactor project

[GT2]

Well I'm adding another project to my list.
I've been looking for a tank for some time now and came across this 200 gal air comp. tank, for $80!
Got it home and cut off some brackets. Then it started snowing so I had to stop.
I still have to clean up some welds and fill some bung holes and then figure out how I'm going to hang some trailer hubs on it.
Once I get the tow bar on it I'm thinking about a platform to mount a vibrating plate on it.

build a slide out of angle iorn use square tube to fit inside and a couple of tie rod hyd cyls that way you can use your remote hyds mount your trailer hubs to the square tubing and there you golist with out a jack or getting off your tractor ive done this on my brillion seed drill and it work great and no over seeding the head lands unfortunately i lent it to a buddy ans it not here to get pics to post with this don good luck

Cool project, what are your thoughts on the hubs ?

Don't you hate it when that happens.

the Hamm vibratory tandem rollers i've worked on, had the vibrating mechanism mounted in the cylinder hub, hyrauically driven. Maybe to increase the life of the drum bearings ??

I'd use slide bushings instead of trailer hub with roller bearings, if you mount a vibratory plate compactor on top of it. The balls or needles wil be prone to metal fatigue.

I'm thinking of welding the stub axles to the ends of the tank, tack them on and then dial indicate them.
Then use the hub/ drums as a surface to bolt the draw bar frame to.

The large tapered bearings in a 3500# axle can take some abuse, however I thought I would make sure the unit is rolling befor turning on the vibration.

I have thought about this some too. I know that the large drum compactors isolate the drum from the rest of the machine large tough rubber mounts, but I never had the occasion to tear one apart and see what kind of bearings they used. But I found on the internet a parts break down of a small 36" hydraulic vibratory roller attachment for a skid steer and it sure seems to indicate that they use rollers in it. Would a large roller spread the impact loads out so that the rollers would not be destroyed? Even the vibration unit is supported with rollers in this unit. Bradco vibratory owners manual and parts book.

I am really curious about this.

Thanks for the info Mike.
If you notice in the parts break down they don't tell you the size of the bearings, but they do tell you the size of the retaining snap rings!
Based on that, the bearings are very similar to the size in my axle. However I'm using double roller tapered and I can guess theirs are flat roller or ball.
Not sure if it makes a whole lot of diff?

These arent ball bearings, but tapered roller bearings... those can take more pounding than balls.

Tim,

Keep posting what you do and how you do it. I for one would be very much interested in reading your progress and successes. As Renze noted the bearings in these both for the eccentric and the drum are tapered rollers in a gear oil bath. Keep us up to date with pics and progress.

Got some work done on the roller today!

First I took off all the brakes and backing plates and cut the axle in half.
Have you heard the saying "I'd rather be lucky than good"? Well I got lucky, the end bell plug holes on the tank just need a slight hit in four spots with a file and the axle will slide right in!

I then cut an access hole in the side, slid the axle pieces into the tank and clamped them with a piece of angle iron.

I rigged up some straight flat plates across the hubs so I could measure the alignment. I tack welded the axle in the center and then unclamped it and moved it around till the alinment was as good as I could get it. This took a fair amount of cut and try.

Next I notched some 5" chanel with the hot wrench, to pick up three of the lug studs. I know it looks crude, but its not high speed or anything so it will be fine. I bolted them on the hubs, cut small slices in the chanel, heated and bent the chanels to almost touch. I dont have my ring hitch yet so I tacked a piece of steel to hold the chanels till I get it.
