Hand Held Crushers?

Chris_J · #1 (**permalink**) 10-07-2005, 09:20 PM

I am not sure if this is the right place.

We are bidding a job, an expansion in a hospital. There are lots of hollow core CMU walls coming down. We are not allowed to use any breakers and/or “noise” generating equipment. Has anybody have experience with a held hand/chain hoisted crusher? I have seen them at a show once but can’t remember who makes them. Any experiences with them?

Thanks in advance

Chris

We used a hand held hydrualic crusher about 13 years ago, It was like a giant c clamp with a hyd cyl and was made from aluminum. We were breaking 8" cip walls with lots of rebar and found that it did work but offered marginal performance over rivet busters. I would think with hollow cmu you would just use double jacks.

I know Golz (picture below) makes one. But like wawrecker said I think you would better of using double jacks instead. I have never used one but, seeing them before they just don't seem like they would perform very well in your particular situation.

Good Luck and lets us know if you got the project.

Guys thanks for your help.

Demojames – Thanks for the picture. That is what we were looking for.

Wawrecker – After giving it some thought and the “logistics” of the job we decided to bid it using sledges.

It bids tomorrow, so I will let you guys know.

Excuse my ignorance, but what are "double jacks"?

Well I considered "double jacks" to mean sledge hammers.

Nope we were not low bid. 4 out of 7. But bidders 3 to 6 were all within 6% of each other.

Hopefully you get the next one. So like it was tight? How low was the low bid?

we have a lot of experience with them! a great tool at the right place! here you can look at the video when we are using one:
YouTube - Darda hand held combi shear HCS6
the noise sounds a lot louder bacause of the camera... but it is a neat tool!
it breaks even really hard reinforced concrete up to 15cm thick (6")!

I will try to upload a video of the BROKK 40 using the Darda cc260 crusher as sone as possible

it crushes up to 26cm thick (10,5")
