What is normal or average fuel consumption for a hard working digger of any size? Pricing a job,I wanted to calculate this for an EX 200-5 Hitachi ,not having a clock an the bowser,I got the fuel tank size with help from King7Two. Works out in tough conditions she drinks 20L / hour. This is 1L / hour per ton of machine. Is this normal for any size machine?
my EX60-2 consumes 5 liters/hour my EX120-2 consumes 10 liters/hour my EX200-2 consumes 15 liters/hour
On average work ,I thing the 200-5 would stretch to 15 L/hour , but at the current job there is no grading , just hard digging. One extra query- does load sensing save much fuel
I have a JD 200LC, the EX200-5's sister. Now the John Deere has a 6068 engine that is larger, more powerful, torquier, and more fuel thirsty than the Isuzu engine, so take that into account. My 200LC burns around 16 litres an hour for typical moderate digging with some smoothing. In pure heavy digging (such as pond cleaning), I can burn up to 22L per hour. Your Hitachi should burn a bit less fuel, so 20L/hour sounds about right for heavy digging. What do you mean by load sensing saving fuel? Are you trying to compare modern computer controlled load sensing excavators to old fashioned non-load-sensing excavators of the seventies and eighties? If you're talking about the "E" mode for the engine, I haven't been too impressed with it. I've found that in tough conditions, E mode slows down digging much more than it saves fuel. The computer seems to destroke the pump on heavy load too easily in E mode. The machine is much more aggressive in tough digging with the H/P mode on, and E mode off. In moderate and lighter digging, I find turning down the engine RPM to 80% gives a better result than E mode. My excavator seems to dig faster and use less fuel when at 80% throttle in H/P mode than it does at full throttle in E mode.
Picking up a 93 Cat 312 later this week, can anybody who owns/runs one tell me what I could expect for fuel consumption? will be using it with a compaction plate to drive fence posts mostly, thanks
Dont know much about Cats but to go back to the Load sensing issue, to compare relatively modern machines to 70's & 80's pre load sensing machines from a fuel use point is exactly whats in my head. I reckon LS should make for significant fuel savings and also increase throughput but I'd love to see figures or percentages, even rough ones. One exception is my volvo EC 160, with LS but only one pump. She drinks nearly as much as the EX 200. Another fuel point is how much has fuel consumption gone down hill since emission regulations started ? sultan, is that a french PowerTech engine? what capacity is it?
The 200LC has a 6.8L Tier 1 American-made PowerTech engine. It's officially rated at just 140 HP, but produces a bit more than that in H/P mode.
what would an ex120-5 use per hour say on half throttle. do you think you would get away with around 8 liters/hour
maybe, my operator use the E to P throtle settings with this consumption data.
hitachi ex200-5 runs on a isuzu engine manufactured and built in japan (both engine and machine) , its burns 155 litres per 10 hour day hard digging loading 8wheelers , with a hill quick hitch and a 5 foot tighe bucket with 5 teeth, no grading, and in the 10 hours work a good driver will load 168 lorries (8 wheelers), there is no difference in fuel consumption on the lc and standard models ,there is a difference of 5 liters perday in the hp mode and the e mode ,in hard digging the machine is more economical at full revs (hp) , while grading is more economical in (e) mode , dont drive the machine with both buttons pushed its a waste use one mode or the other! hope that helps. cat 312 will burn 117 litres per 10 hours work ex120-5 will burn 92 litres per 10 hours work
My 312 is a '94 ...... I just finished a job late last fall doing exactly what you are asking ..... even tho we were already on Arctic grade fuel (watered down CRAP) ... because of what time it takes to probe and vibrate the posts into tough rocky/hard clay ground, and moving from post-next post, the 312 burned F-all for fuel ..... we put in over 5km's of posts, @ 5meter spacing including tie off's at 400meters (extra posts) and installed range gates as needed ... 40-50 posts/hr were possible (depending on your helpers and prep work)..... did the whole job with just under one tank of fuel (230L) .... I use a digital flow meter on my fuel supply tank and if I remember correctly, put in about 225L .......... in hard digging the 312 has NEVER burnt more than 10L/hr .... in construction site work I can usually base fuel costs to be around 230L/33hrs of work ........ but using the vibrator to drive posts the 312 was never over TP#8 on the meter and that is only for a few seconds (a post never took longer than 1 min to install including probing the hole) and it took longer to relocate and spot the next post (2mins... slow laborers....lol..) depending on your vibrator and gpm needed to find the sweet spot of operation is what will determine fuel consumption ....... I know i'm gonna get flaque from the guys out here for using metric numbers ... but to keep it simple 1-roll of barbed = 400M +/- 20ft .... and ~5M = 16ft
cheers cj, thanks for the info has the ex120-5 an isuzu engine i was thinking of buying either an ex60-5 or ex120-5 for my farm i kinda like the idea of the ex60-5 but im not sure if it would be enough. ive a good bit of stone walls to shift and tree stumps to take out aswell as drainage work do you think the ex120-5 would be a better bet cj also i want to buy a fairly clean machine so hopefully maybe in a years time it wont lose to much money thanks
Volvo 210c doing finish/site grading and pretty much the same when doing bigger condo basements its burning 9.7L hr. Sewer and water apps when its just making trench its 11L/hr Volvo 290c in heavy trench is 18L/hr
120 -5 has an isuzu engine but a good 120-5 will cost you up to 25,000 euro at the minute, and a 60-5 will cost you up to 20,000 for a good one , 60 a great machine but 120 would suit that kind of work better , you will buy a 120-3 or -2 for 7 - 10 ,000 euro and sell it on again in a year or 2 for similar money, dash 1 machines are making up to 13000 ,dash 15 and uho models are being sought for export to china and the east and africa thats why they are so dear!
cheers cj, and happy belated st paddys day. haope you had a great day yesterday. im going to be buying a machine now in the summer. i was thinking along the lines of the ex60 but i think some of the work would be abit hard on it. probably go for 100 or 120. i just want a machine that holds its value and a machine the doesnt cost me alot of money in terms of brakedowns. in a year or 2 i might sell it again and hopefully not lose to much money. id probably buy a -1 machine if i came across a nice clean one. if not a -5. i might start a thread for the hitachi ex120.
