Cement breaking Machine

[JWD1312]

I was wondering if anyone out there has any ideas or pictures of a home built cement breaker, either tractor mount or stand alone. Something that would break up cement drive-ways or sidewalks.

This past summer, Son and I rented an electric jackhammer to break up a sinking 10x15 ft patio to make way for a deck. Will NEVER do that again. It took us about 5 hours of really hard work to breakup the concrete--and ours didn't have the reinforcing wire installed correctly--it was mostly on the bottom of the concrete, so it was easier to break up.

Never again--If I ever have to do something like that again, I'm renting a bobcat with a front mounted jackhammer.

We manually loaded three trailer loads of concrete, hauled it off, and manually unloaded it.

Way too much work!

I made one a few years ago for a friend that was copied from another friends drop hammer he had on his work barge. He mad a winch from a car alxe and differential assembly with drum brakes and made a tower of 3 inch channel with a heavy weight that slid up and down. I made a 10 foot tall tower that same way as his and used a steel box with lead inside of it with a sollid steel nose on it. I had 2 master cylinders one on the drum side to stop ot hold the weigh and one to lock the open end drum to make the the cable winch hoist.
I fixed it wo where the fram would be lowered to the groungd to make the tractor more stable when the weight was in the air and to take the load off the tractors hitch. just turn on the pto and start holding and releasin the brakes. Itw would shater the concrete in upto a 12 inc area. Id take my back hoe or excavator and dig out the busted sections. My frien has used this thing dor about 5 years and it also doubles as a post driver. Im unable to get a picture of it but im soon to start building my own soon.

Sidewalk is to handy to breakup. I recycle it. Ex: few yrs back local church needed to remove 150 ft of 4ft sidewalk to add a new addition. I found that if I jacked up on the sidewalk it would snap at the stress seams. I could then cut the reinforcement. Sit the 4x5 sections on my trailer an haul them to the farm. I only broke one section. I use them for barn floors. I put a base of limestone as necessary to have a level surface. Place the slabs on the base with about 18" of space between. I determined this space as the distance needed to get my hammer drill. To cut them you can score them about an 1" deep with a grinder or saw. same as you would block or rock. Drop them with the loader they snap nice and clean. I drill 3/8" holes 16" on center around them 3" deep and drive #3 rebar into them. Pour concrete and trowel it smooth. Makes a very servicable farm shed floor for very little money. Over time you might get a crack or two nothing serious. Put two of them together and you have a nice place to drop the plow or disc, fireants and weeds can't get to it. It's not hard work! I'm crippled up, the machinery does the work, just takes time, which I have plenty of these days. I wish I could find a way to move slabs!!!!!!!!!!! /forums/images/graemlins/grin.gif

We would lift it up with the FEL about 3 to 4 inches then hit it with a sledge hammer or stab it with a pinch bar. way to much work. got and high schoolers looking for $$$

i like the idea of recycling the sidewalk, thats what i did when some friends up the street wanted to get rid of a sidewalk about 3 ft wide in front of there house leading to the mailbox. i happened to be driving by and saw them chipping away at the edge of the sidewalk with a sledgehammer, i stopped to talk to them and see what they were up to and i said that if they were gona get rid of the sidewalk i would gladly take it, after givin me some odd looks they went how the heck ya gona move it? i said with the tractor, i went home got my ford 8000 with the 3pt forks, drove up there and tilted the forks down with the hyd toplink and slid under the sidewalk, lifted an 8 ft section and drove it home, the whole thing came up fine this way with no damage other than the edge they had chipped away. saved them alot of work, infact they offered to pay me for having removed there sidewalk but i told them not to worry about it i was just happy to have gotten the sidewalk pieces. they are great for the muddy area in front of my goat barn
