would a fleet of 631d cat scrapers be a good choice for a really big earthmoving project here in illinois soil im talking really big job or would a fleet of terex 18's in great condition work better, back to that production and cost per cubic yard thought there is going to be very tall scraper mounds and some stuff will be stickey some fill will be heavy wet clay and soft conditions for sure I have never seen anyone use 31's around here i have seen 37's in landfills with alot of hardpan in the cells would 31 be a good choice or would the terex be better choice
Double barrels beat singles in soft conditions
i know, really as i have a few twin engine scrapers of my own, just wanted to see if any one had opinions i think 631's will have trouble especially if it rains as they dont have all wheel drive and would'nt you think that they might need to be pushed and maybe pushed in the fill if it gets bad. just wondering how they would do surely they would cost more per yd for even stripping topsoil than the terex 500,000 plus yds topsoil to be stockpiled high anyone operating 631's that can compare them
Hi fiat A few questions that may help us give you a better answer. What would you be building? How long of hauls and from where? Borrow pit or common dirt? What do you have to push them with? (ratio of cats to scrapers and size of cats) I have built a lot of roads, highways and subdivisions in heavy wet clay with 31's. It's slow going until you get a good haul road built....traveling at old Terex speed. But throw all support equipment you can at it. Disks, Graders and Packers. Scrapers travel one side while support equipment works the other. Once the Scrapers side gets punched out bad enough trade sides. Each time you trade sides you will get going a little faster and before you know it you are hauling in eighth gear. Also keep loaded Scrapers and empty Scrapers on their own trail....kinda hard to do because Scrapers of course always want to take the smoothest trail when they can. But if you can keep them apart the return road last longer speeding up the cycle times. If the method above can be used I would go with the 31's. If not then the twins could be the better choice. I guess a lot would depend on the quality of Operators available to you as well.
well first just the 200 plus acres need stripped of topsoil black dirt and 3 stock piles of where to put the dirt, haul is going to be 2500 to 2800 at the longest other you wont have good clay to build a haul road until till this is done and the next step 0f the project begins
If you do decide 631D's will work, the people I normally work for might be looking to sell some of them. Or so I was told. They have 8 or 9 of them and they are located in Council Bluffs, Iowa, right now and have been sitting for the greater part of the last 3 years due to slow work. Email or PM me if you are interested, I'll do some checking. alan627b AT hotmail.com
Wouldn't it be worth it to strip an area to mine some clay for haul roads? It's hard to say without actually seeing the site, but I would likely build some haul roads strategically placed so that they could be used for the stripping as well as getting to the largest fills.
I am looking for the CAT equivelant of a WABCO 333F Scraper?
See if you can find some reference on the internet to Cat's former model 639. They haven't been produced in years. The closest thing today would probably be a 637 auger scraper. I'n not sure they are in production anymore either, maybe as a special order.... Good Luck.
Does anyone know where to find original list prices for a 1977 Cat 631d Scraper, a 1978 Cat 631d Scraper and a 1974 Cat 651?
if the dirt can be loaded without being ripped 4 637ds or es would be best with a 9L, if conditions are really muddy 27s or at least a few are good due to the lighter footprint, and double shift them
Theres an outfit up here on the sunshine coast Shadforths who had 2x 639s, think one was a converted 637, saw one of them on a float the other week. There were also some over in WA at Eneabba in the mineral sand mine, thats going back a bit though. Cheers RDG.
RDG; haven't heard the name Eneabba WA Iworked for bell's on HD31's /D9G's657/651's and on the 988 loading the bin, Brings back afew memeries Cheers leroy
G,day dirt doc Did you ever find a Cat equivalent to the Wabco 333F? I am sure that such a thing is not possible: there is no equal to the Wabco machines for production at an econonical cost per yard! Believe me I know, I own and operate both Wabco and Cat scrapers. The Cat equivalent to the 333F would be the 633; ie single power, elevating scraper of approximately 32 cu yds capacity. The Cat 639 equates to thw Wabco 333FT; ie twin power, elevating scraper of approximately 34 cu yds capacity. If you can find a good 333F, I for one would recommend you buy it. All the best Gordon
we got quite afew 639Ds running around other here, they seem to be the weapon of choise for topsoil and sand a company from WA called piacentini ( www.piacentini.com.au ) they rebuild them pretty good to with nice mod's like fitting D4 dozer chains to their elevator flytes and getting their 631/633/639D scrapers down to <82Db noise rating Tomas earthmoving has afew 639Ds which are "made up" units, I've spent alotta time on a 639D from another company there mist be at least 30 around WA
