#Caterpillar d6c towing the scraper manuals
I note, according to the manuals for the Komatsu the drawbar pull vs speed is almost identical for the D41/D39.
The cat D5M/D5B appear to be more than capable of pulling an I-950 scraper (what about the lighter D6D?) I have included both the D39EX and D39PX in the line up. The D41P-6 are not so prevalent.īelow is a quick comparison (hp / weight / ground pressure) for the D39/D41 and the D5M/D5B/D6D?. Further, if I was to purchase a D39PX-22 I would not need to import the machine which would help speed things up. The XP machines (LGP) seem to be very popular. I note that Komatsu also have a D39PX-22. Now, my problem, how does the weight of the machine and ground pressure factor into the capacity of the machine to push, or in my case to pull a 9 yd struck scraper up hill? For a D5M I can expect the machine to have an additional 50%-100% hours and to be, on average, 2-6 years older than the komatsu. Pricing is tilting me in favour of the Komatsu. What is missing here, and where I am stuck, is on the weight of the respective dozers and how I can translate this to drawbar pull or similar. The list of scrapers is not yet complete, but there are a fair few to go of.īased on the D5B (105 hp) / R568 combination and D5M / I-950 I have several dozer options in that hp range:įor those kind enough to take a peek you will find a number of dozers listed in the sheet (hopefully others will find this info useful too!). In sheet 2 of the spreadsheet I have been populating the specs for different scrapers. I have uploaded the file toīelow is a link to a screen shot for reference. The info is by no means validated / correct, but the best I have, to date!Īpologies! I'm unable to share the excel file on the forum. Most of the information comes from Richie Specs with a few corrections where I have found anomalies. There is a spreadsheet sheet linked below in which I have populated a list of Dozers and their relative spes. For my inexperienced eye, it seems to be doing ok.? The snippet lists the estimated hourly production for a D5B with a R568 scraper in tow and indicates that the D5B (105 hp / 11700 kg) is capable of pulling a 9yd struck load.Īs further confirmation, there is a vid of a D5M (110 net hp / 11700 kg) pulling an Ashland I-950 ( ).
I have pasted the snippet below for reference. In terms of sizing the correct Dozer for a 9 yd scraper (I feels as though I am working the problem backwards…:/) the only concrete input I have is a page out of the Caterpillar performance handbook. I could go for a smaller dozer, but I would like to maximize the capability of the machine I am purchasing for future, potential work (no sense going to small.?). After a little more research, I thought I had settled on a Komatsu D41P/E-6.Īs a bit of background, attached is an excel sheet which lists the machine specs for the various machines I had been collating info on.Ģ) Relatively low hours machine ~<= 4000 hoursĤ) (V)PAT blade – I don’t intend to do any land clearing.ĥ) Capable of towing a ~9 yd scraper. For the sake of economy/available funds I have had to lower my expectations and had leveled my sights at a D5M sized machine. Let me start by saying I would like a D6T. Also, having put in a bit of time to understand a little about the machinery I would like to share what I (think!) I’ve learnt. The desire is to tow a scraper (scoop) to form the access ways – the bigger the capacity the better. The job is a small subdivision in steep, clay country. Hope to have a machine on the job site end of Dec 2018. I have a job that is big enough to justify purchasing a machine (my first). I would really appreciate some help choosing the correct dozer for the work I have scheduled.
