Jumping jack tamper question?

I know nothing about these tampers. My concrete contractor is the one that's usually there to save my behind. This situation is different. I need to get a use one. It maybe cheaper to buy use then to rent at 85 bucks+ per day. I have no place to store the large amount or soil on site. No room on the street. it is one of those one car only narrow street. I found this one, a Sakai, without a boot for under 500 bucks. Anyone know what I need to look for?

Sounds like a deal. I know a small hydraulic pole tampers was one of our trucks when we bought it, the damn thing blew up this summer, and it will be way more than $500 to replace it.

Back fill behind a short retaining wall. Worst thing about this is that there is no access and the soil has to be wheel barrow then carry in by buckets down about 20 steps. Its holding up a free standing deck about 20 inches off the ground.

the plate kind are cheap and I can even get one at Harbor Freight for about 500 bucks, then throw it away if it need be. I need to compact soil, so the jumping kind is necessary. My issue is the lack of room to store the soil. It has to go into the back of the house hand carry in with 5 gal. buckets. My concrete contractor smile at me when he quoted me the price. I need to fill 65' x 8' x 3-4' high. there are three sections. That's a lot of dirt. Even he suggested that I buy the compactor and have my men do it slowly without pissing off the neighbor blocking the street. I get all the fun ones. No complains here, just glad we are working.

We aren't really sure, we were running it off the aux hydraulic lines on our truck. The truck bogged down, and then the tamper spewed hydraulic oil all over the place. Split the case of the thing wide open. I'm guessing something plugged the fluid out and it pressured up and blew at the weakest point.

I won't offer much experience in terms of buying. I have rented one - that thing is like holding on to a 400 lb jack rabbit! wholly cow!

You've got a lot of work ahead of you. A neighbor and I filled in a low area (settling from organic debris that was buried by the house contractor) and it took us about 6 PU truck loads and we were able to drive right to the area and shovel the dirt off the trucks. Ran the tamper after each unloading.

67 yards of fill in 5 gallon buckets???? Fook me. Would it be possible to haul in with a Dingo? Could you fill with sand? Can you deposit with a concrete truck and pumper truck????

I picked up some concrete tools a few months ago and one brand that seemed alright was Wacker brand. Spy craigslist and eBay for ones in great shape. I really wouldn't worry about your tamper. Worry about finding an easier way to get the fill to the site.

People tell me the best compactor was a rented one. Wackers are the most common and parts are available. Fook me is right, no, fook my guys. Getting the dirt back there is not too bad with wheel barrows, but the steep parts and the stairs is going to be a mofo. I have thought of slurry, but the smart architect spec out soil and he wanted a pretty garden or a vegetable garden there. This inspector is a royal pain the my arse, but I still might shoot slurry a couple of feet then cover with soil. Hope the plants and tomatos grow well with the surry under there. that will eliminate half the work. A rented conveyor belt or some sort have crossed my mind. This is not the first time I was chosen for the most f'k up job site. This one has one thing going for me. It is all down hill. the last one was up. fooking 30 degree+ hill side. We did the interior (all the wood work) of Chemosphere. They decided to have us install the slate floor. That was a lot of humping up because the elevator busted half way into the job. I helped, lead by doing. I am done leading.

Which would you rather use in that situation? I'd go for the pneumatic one.

I don't have a compressor big enough to drive one. Still, I am thinking of the used electric one on top of the pic. If I can get it to run 7-10 days, then I am ahead.

I carry both the Jumping Jacks and the vibrating plate compactors in our rental fleet. They both compact (obviously) but with different purposes. The jumping jack is suitable for compacting trenches, compact areas etc.

single-way Vibrating plate compactors are a smaller plate compactor for compacting sand, gravel etc. Keep in mind you will only be able to penetrate the soil a few inches. Make sure you compact often between the layers of back fill.

The reverse plate compactors are larger machines (300 - 1000 lbs) and will compact deeper and denser.

For jumping jacks we used to carry the 2-stroke Wackers, but have switched to the Weber 4 stroke. Great machines. You will be able to find lots of used Wackers (green machines) as the new trend is the 4 stroke units. the Wacker is a b.tch to start, (2-stroke) but well build and durable.

The small plate compactors we rent range from 125 Lbs (small jobs retaining walls etc) to 300 Lbs. This is the own weight of the machine, with a tamping force of 2500-6000 lbs. DO NOT buy a unit from the discount store. They will be useless. If you want to buy, get a used one from a rental yard, and sell it when the job is done. Good brands are MBW, Wacker, Weber, Dynapac, MQ/multiquip.

Reverse plates is a different beast. Ranging from 300lbs to 1000lbs, either diesel or gas. Price new goes from $5000 up to $15000 for a diesel 1000 lbs.
