This got emailed to me from a friend of mine, he got it off old matey in the US. It looks like the rear end of a 973/963 track loader up the front. Does anyone know anything about them
The drive is at the front of the tracks. So when driving forward, the top of the track is pulled tight and the bottom of the track is loose and bunched up. The opposite of a dozer or excavator when they are driving forward. So what is everyones opinion on this? There are a lot who say that tracking in reverse in a dozer or excavator increases track wear, due to the bunching up of the tracks. But here is a machine designed to do just that?
A little info about it in this link: http://haddick-gewaesserbau.de/imedien/mit.pdf
Yair . . . A couple of things Plant Fitter . What you say about wear in reverse theoreticaly right . . . with standard tracks. This here jigger has some different configuration . . . and with that many rollers under it I don't think there is much chance of any bunching!!! Cheers.
Video here - http://www.youtube.com/watch?v=fZx0nuqidk8 The tracks appear to have inner and outer links, like a motorcycle chain. Check out the komatsu - spins like an excavator - http://www.youtube.com/watch?feature=endscreen&NR=1&v=G3Q4VbE_KVo
Hard to tell if it started off as a 963D or 973D. They turned the cab around and the undercarriage is much longer than any standard track loader UC. JMO but that looks like an expensive way to haul dirt.:beatsme There are certain conditions where this machine would shine but it would definitively be a specialized piece of equipment, however an artic would beat it $$ per CY wise on a daily basis. Interesting machine none the less, thanks for posting!:drinkup
It definitely started as a 963, as it matches engine specs with the D model. I like the concept, but not as a run of the mill hauler. When you have some tough conditions, it would do nicely. I see it has a blade in the rear, and the "pan" that keeps the dirt centered as you dump makes it ideal for roadbuilding in swampy areas.
Thats a first!
Yes you are right:tong
The undercarriage is Cat System 1 which has the rotating bushings. That would mean that it wouldn't make any difference which way the tracks go over the sprocket. Can't say as I like the full length rock guards. The machine is obviously made for swampy ground or adverse slope conditions and the side shields would only hold the sticky stuff in on the rollers. I don't speak the language so don't have a clue about what the two gents are saying. My impression is that they are doing what DJB did years ago by taking an old concept and marrying it to new technology. I don't figure it to be a big seller in the US market.
Respect for all what cat do !!!!!!!
The machine is called a Haddick Raupentransporter, (model) CIT 5719. It made by the German company Haddick, using a mix of Cat components. "Raupentransporter" translates as "Caterpillar (tracked) vehicle". These style of transporters are designed for hauling materials through swampy, marshy ground that has a reasonably firm bottom, up to a metre or a little more, down. There's a lot of this style of marshy ground in Europe and in SE Asia. I'm not sure if the Japs or the Germans pioneered the building of these style of specialised transporters. The Haddick CIT 5719 can be fitted with different bodies, including a waste compactor that dumps as well. The company seems to be reluctant to release any info in English. There's a few videos of the rig at Bauma, but the company reps only give interviews in German. Here's a quick description, courtesy of Nicks Blogg .. "The Raupentransporter CIT 5719 is a 27 ton tracked dump truck and is powered by a Caterpillar C 6.6 ACERT engine. The machine uses many components from Caterpillar and indeed the engine is similar to the ones fitted to Caterpillars 953D and 963D track loaders. This machine, which is built by W. Haddick GmbH & Co has a load capacity of 30 tons making it the largest track type dumper currently available. It has a very long undercarriage and wide track pads which makes its ground bearing pressure an impressive 0.61 kg/cm 2 (8.67 psi - with a full load). The dumptruck is also equipped with a dozer blade at the rear, which enables the operator to discharge and level his load in one operation, which also eliminates the need for any additional machines at the tip area." I'd say the W. Haddick company is working in with Cat for the supply of many basic components from other Cat machines, and Haddick have a patent on the frame/chassis design, and build it in Germany. Something similar to the technique introduced by Dale Elphinstone of Tasmania, Australia, when Elphinstone designed and built a range of underground mining equipment that used all Cat components. As most would know, Cat ended up buying Elphinstone and they simply became the underground mining line of Cat products.
The first transporter in this style that was built by Wilhelm Haddick GmbH & Co used a Liebherr Litronic 732 for the basis of the machine. As with any loader or dozer that Liebherr built, the 732 was a POS - and it appears Wilhelm Haddick GmbH & Co saw the light, and moved over to Cat components, knowing full well, that with Cat on it, they might have a whole lot better chance of selling a few. There's a thread with a few good pics on the DHS diecast forum, showing the Liebherr version. http://forums.dhsdiecast.com/default.aspx?g=posts&m=949292
angle of approach on the front of it looks worse than a normal adt, it looks like it also has no real front bumper... definitely needs to be higher off the ground too, i think this thing would have a hard time getting through the same haul roads a 730 would wiggle through, if its made for real sloppy soft conditions they should have put wider tracks on with some big grousers, not the smooth tracks in the pictures.. and sorry but that ladder is getting ripped off on day one once it gets in some nice wet sticky clay whats the max speed? obviously much slower than a 730... whats the cost per hour of the undercarriage versus the cost per hour of the tires on a 730? you'd think the haul roads would stay together better with a machine like that but when it's turning sharp i'm sure it makes a real good mess when things get sloppy that blade on the back is an incredibly bad idea. the theory is that it can knock down its own load to eliminate the need for a dozer in the fill, but then you'd need a dozer to clean up the haul roads once in a while anyway in the soft conditions this thing is apparently designed for... Having this thing blade it's own loads would seriously slow down its already ridiculously slow cycle times drastically if the operator is trying to blade the fill every round (in reverse, not being able to see the blade worth a damn unless the box is up) when he should be heading back to the cut... the hoe is waiting for the truck to come back for a load at $250/hour, that right there covers the cost of having a d6 on the fill looks like a truck designed for soft conditions by someone who's never been on a dirt operation in soft conditions
