I just learned about this beast. Here's a company article and a local news video.

Absolutely awesome, Eric P needs to do a WA1200 with a demo bucket now to partner up with it.

Wow! That is so epic! Thanks so much for sharing. That thing could take apart aircraft carriers. LOL!

I agree with some comments highlighted in the linked article regarding the size of the hoe. What justifies such a big excavator in size just for holding a shear tool: ballast? hydro unit efficiency? I am not a demolition specialist, but I wonder why wouldn't an Hitachi 870, or Cat 374-390 with oversized counterweights, and pimped up hydraulics wouldn't do the job: more agility, easier traveling logistics, and how about fuel efficiency, although it may not be such a concern. ...well, other than breaking a world record, and the related exposure and advertising for a company willing to build itself a name....  Just my humble opinion. Stephane

Now, THAT's a shear!!!!! But i totally agree with Stephane..... On the top of that, that machine will require a whole crew, along with some cranes and lowber trailers in order to be moves, plus the cost of the fuel.....  But still interresting and very impressive. Thanks for sharing. Max.
Cat 245.....Now and Forever  I am looking for industrial auction brochures from Ritchie Bros, Miller & Miller, Forke Bros, First Team Auction, Max Rouse, etc from the 70's, 80's and 90's.I am a collector and heavy equipment enthusiast and these pamphlets are loaded with nice pictures of cleaned and freshly painted equipment.Thet don't have much value once the sale is over but they are a great help to me in preserving the memory of machines that are no longer being built.Please, help my hobby by looking in your old storage boxes and file folders for these old auction sale brochures.Your help is much appreciated.

Back in the 1999, demolition contractor DePaepe from Belgium run a Liebherr R994 with a LaBounty shear - it was a MSD 142 weighing about 64,000 lbs. The R994 cut down the power plant on a mining complex. After shear work was done, the shear was removed and the stick reattached. With its bucket, the excavator then removed the foudation works of the power plant - concrete blocks weighing 45tons - a sort of work where its digging forces surely proved to be helpful.
Just a guess, but the stick is still on the PC4000 and you could switch between bucket and shear faster then on the R994. OK, maybe it's just a big, yellow PR trick... but wouldn't it be cool if there was really a reason you'd need the Komatsu to do the job?
After all, in Australia as a mining country, you could maybe resell the PC4000 much easier then a beefed-up, specialiezed CAT 390. Still scratching my head on this monster...
Cheers,
Max

Dunno about that, there's a near new PC7000 parked up for the last 2 years waiting for a new home

Uh, this is about 4 1/2 times the weight of a 390, a 390 could never reasonably be built up to handle this shear in even a boom mounted application let alone stick mounted. It's all about tool size and height, the more you can cut with machine the less you have to do manually, which is viewed as much safer and is for sure much faster. I don't think a successful business would be that if they would throw down 5 million just to say we have the biggest without justification. Just my opinion.

Does a Drake 4 X 8 weigh 15t? Mr. Scholz wrote:Back in the 1999, demolition contractor DePaepe from Belgium run a Liebherr R994 with a LaBounty shear - it was a MSD 142 weighing about 64,000 lbs. I have seen photos of this unit, but I cannot find any information quickly about the MSD 142 and it is hard to imagine there being a heavier unit nearly 20 years ago. Do you know the R994 demo unit from Australia?

Thanks for the pictures of this beauty, Digggerr! I like the white livery for demolition machines very much. Man, that thing really looks muscular with it's demolition grapple... I googled around, there used to be a nice job report on DePaepes R994, but it's gone. But I found a nice report on "your" R994 and hey what? It also carries a Genesis GXT 2555R. Someone on facebook wrote that's the same type as used on the PC4000. Right or wrong? PLEASE CLICK BLANDLY

Ah, here, I found the German version of the DePaepe jobreport. LIEBHERR R994 DePaepeThe MSD 142 was sometimes also referred as MSD 500. It weighs 28 metric ton, is 10 meters long and has an opening width of 1.65 meters. Cutting force is 3,200 metric ton. Technical data on the GXT 2555R according to the blog I linked: "This is the first GXT 2555R mobile shear ever produced It is the world’s largest and most powerful mobile shear attachment ever made It was custom built for Liberty Industrial’s Liebherr R 994 It is capable of cutting through a 1.2 metres thick steel I-beam in a single bite It weighs more than 30 metric ton, is over 7.85 metres in length and 2.9 metres tall It has a cutting force of more than 3000 metric ton and a reach of 6.5 metres It has a jaw opening of 1.4 metre and a jaw depth of 56 1.4"

I'm willing to bet the weight quoted is the transport weight including the container it is lashed to.

Cheers,
Max Well that's a good point; I haven't thought of a "temporary use" of mining equipment when mining gets slow. Renting a readily available mining excavator located near by and getting it fitted with that tool for a major contract could make good sense after all... S
