I'm a sceptic/careful. First thing I do is ignore the marketing and sales bullsh*t! and then see what happens in the real world with a day running in hybrid and a day with it off or maybe half the job one way then the other and measure the fuel used. Then cost out any fuel savings against increase in purchase price vs the equivalent non-hybrid machine and how much longer it will take you to pay it off. I also like to buy new systems once they have a few years of others running them and let them have the pain. Love the innovation and we are going to have to make better use of these systems as time goes on.
Well at least the pump's the right color, gold. I would imagine it'd take a pretty good size poke of it to replace that bad boy. Nice unit, I'd own one, Volvo makes quality equipment.
Not sure I fully understand, but if the high-pressure fluid stored in the accumulator is used to feed the pump, that means the pump doesn't have to work as hard to raise the pressure and provide flow as if it was taking input only from the normal accumulator. Having higher pressure input like that may reduce wear in the pump and everything feeding it. Kind of like kick-starting the entire hydraulic system for free. Neat it that's the way it works. One interesting experiment would be to operate it by lowering the bucket farther away from the cab and compare the amount of fuel when you lower the bucket near the cab. Maybe a few tanks would tell you something...(bet there is a Volvo engineer who could tell you off the top of their head.)
It doesn't dump it into the manifold. It dumps it into the bent axis motor bolted to the aux drive on the pump to give additional drive power from the stored pressurized fluid. The hydraulic motor supplements the torque provided by the engine to drive the pump.
@@bigfunwmu thanks. But it is providing torque assistance so everything upstream doesn't have to work as hard. I think that was what I was trying to say...
@@TomTalley the pump has to work just as hard as before, the torque assist takes the load off just the engine and puts it on the stored energy in the accumulator.
Small accumulator compared to the one's I saw in the military. But the other advantage of an accumulator in the system is reducing shock to the hoses and valves. Have a good one.
@@JackHudler set up right, they keep the flow constant and smooth, but that type is between the pumps and the rest of the system. Plus they can let important things function for a bit if the pump dies.
Its fun playing with someone else`s new toy - kinda like when we would go test drive new cars, say thanks and leave. You really need to test that new machine on the boulders you dug up at the Rock Hill Animal Clinic site. No squeeky track pins as well.
All-electric excavators are starting to appear. Reduced driver fatigue and almost silent in operation will be a big step forward, apart from motor efficiency. There will be those who dislike anything that doesn't make a big noise and burn diesel fuel but such heavy vehicles will become more common as battery technology improves along with lower prices. This simple improvement from Volvo is to be welcomed.
Maybe you could talk them into putting one of your LD18 buckets on it bro. Anything that saves money has to be good these days. Cheers for taking us with you. Safe travels
I'm glad they gave the option to turn it off. Cat tried this and it was a huge failure. The 336eh we had got about 40% less production. It felt like running a machine from 1000 miles away with dial up internet.
15% fuel savings, 30% more expensive, operator need to run it 6 days a week 10 hours a day for 5 years to break even, by then its worn out or in need of major overhaul!
Did I read somewhere that they are using heavy equipment in deep mines like drones controlled by telemetry from a safe control room? Seems Volvo did some research in that area. One day we can watch Chris Live Stream from his desk as he monitors yellow robot track hoes clearing ponds and hammering rocks by remote control. WOOHAH! Aircraft use the same type of systems and have for years. Them big girls are gettin' fancy!
Interesting video. I worked for nearly 40 years at a heavy industrial plant and hydraulic accumulators, which is what Volvo is calling a hybrid system, have been around forever.
Yes, accumulators have been around forever, to smooth out pressure under demand, store pressure in case of supply failures etc. This is an innovative use for one and is very cleverly implemented. It's basically a turbocharger for an hydraulic system- turning waste energy (dumped return to tank pressure) into an energy source.
Volvo has always been an innovator when it comes to equipment and they make really high quality stuff but I’m a CAT guy and always will be. Still a nice unit and I’m sure Chris will have this hybrid on his other units at some point. By the way Chris I still have 120+ miles of ditch and 13 ponds that still need to be cleaned.
Because small chamber sucks up the pressurized oil from the large chamber with minimizing energy loss, it needs just a half of the target working volume. And smaller acc volume matches well to the typical boom lowering pressure building up in the acc. Otherwise every pressure difference makes energy saving loss with a larger acc. That is the key.
charging an accumulator to then send the hydraulic pressure back to a fixed displacement hydraulic motor. this is to spin up the hydraulic pump and engine without the added load when performing the next high load cycle. i would like to see a smaller diesel engine/generator charging a counterweight sized capacitor. the stored and available electric power would be used to run electric motor for machine hydraulics. swing motor could then also be electric so regenerative power is added back to the capacitor storage when swinging.
Any time you change energy from one source to another, you are wasting energy. This system is genius in it's simpicity and use of existing off the shelf hydraulic components and principles.
WOW, Chris, I AM impressed. I'm not a, "Green Guy," but when I can save a dollar - I've saved a dollar I can invest somewhere else. Taken as a whole, look back at your records for the past year, and look at the number of hours you've put on an excavator. Take your actual fuel expenses for that year and subtract a (conservative 10%), and then ask yourself... was it worth the investment? Put a different way, my wife asked me (50 years ago now), "WHY do you need that table saw - you have other saws." Well, that table saw didn't pay for itself in the first year, or 5 or maybe even 10 years, but over the next forty years....
Well Chris that is a nice machine and with it having the standard sticker on it it should be able to carry 3 cubic yard bucket. If you get it with the short stick boom you can run a 3.7 yard bucket on it and you can sure tell the difference when loading a truck but with the 3 yard bucket you can heat up 5 yards in Sandy Clay and load a 24 yard trailer with five buckets but anyway brother you and John stay safe and keep the videos coming man
Nice Machine! Me drive a Hitachi 210-5 hybrid, but the hybrid Systeme is only active when swing more 1/4. The Fuel goes down quekly when crush concrete!
I really appreciate that Volvo is a forward thinking company and they have chosen you to be their spokesman. I think that machine would look real good with your bucket design on it. How much lead time till we see the new 220 in action? lol Thanks for the videos.
The Volvo CE EC300EL Hybrid have almost the same transport measurements as the 250, it's just a little heavier and much better. And the hybrid will for sure come into other models soon!
Chris is at a dealership, something new is on the horizon, sponsorship? Congrats! Deep hole digging ( long downstroke of boom) will give you the most "Regen" of power.
Ain't you lucky over in Scotland we are paying £7.85 for a gallon of diesel which is equivalent to £1.55 per litre so the hybrid would be a good idea over here great work with the videos addictive watching 👍
I like the idea of saving energy, my only thought is how long would it take to get your money's worth out of the difference in cost of that upgrade. At $45 quoted estimate, I think it would take many days to see a real savings in cost of the upgrade. It seems like the machine is more active.
My guess is you'd have to run it 50-60 hrs per week, year round to start saving $$$$. No way could you recoup it if the machine sat for weeks between jobs
We had an accumulator system on our hydraulic systems where I used to work before retiring. If the Volvo works on the same theory, you should have noticed a cushioning effect on the movement when operating the controls. A shock absorber effect so to speak.
It sure looked to be a very stable machine. I'd like to see a size comparison to a 220 or a 250. Chris probably told them overseas he needed better fuel to hours percentage.
I think if you got out a precise enough stopwatch, you would find that those down-strokes where it charges the accumulator move just a little bit more slowly. I can't know by how much. But if it's significant, it could mean you - the operator - get less done in a day by one or two percent. That literally might not be worth those fuel savings. Especially for someone such as yourself with multiple machines just parked on on-going jobs because there aren't enough operator hours in a calendar day.
The reason you can shut it off is when it is not working correctly but you can’t stop for an hour and wait for a mechanic to get out there hopefully you can keep running. The company I work for moves about 10 million yards of material all by hoe and on road and off road trucks and probably 7 of it from thaw to freeze. Every hoe breaks down but when it’s something like that it pisses my boss off 100 times more. If I sit for an hour there could be 30 trucks sitting there. Had a lot of issues with the 349s when they came out and a couple of them still have problems sometimes. I wouldn’t trade the 352 I run for anything. I loaded over 60,000 side dumps last summer with it and was broke down once for a starter and twice for a hose break. They are trying a Volvo on a different job and I asked the operator how he likes it all he said was the seat was really nice.
The little knowledge that I have about hydraulic accumulators is that they need to be checked regularly to be sure oil hasn't leaked into the air chamber.
The savings sound great but...what is the extra cost of this Hybrid technology and how many years will it take to recover the extra costs. Does it make sense for an owner/operator?
Hitachi and cat tried that years ago but it didn’t really pan out. But both of those manufacturers have a regen systems in their valving to capture some of that boom down oil.
Eaton Hydraulic launch assist was basically that same thing on garbage trucks years ago. Braking would drive a pump building pressure into an accumulator then pressure was released as the accelerator pedal was pressed. Cool idea but it failed due to complexity.
Voith are using the energy captured from hydraulic drivetrain retarders to do this sort of thing as well, much simpler system as the retarder is already a form of hydraulic pump. Store the hydraulic energy and release it back into the retarder as drive power. Great for buses and other stop/ start vehicles.
New, better does cost more - but Volvo claims payback in saved fuel in about 2 years. Obviously applied to the largest cylinder first and which will be applied to other hydraulic solenoids in future. Kudos Volvo
So when are you going to be a sales rep for Volvo , since you work 24-7 another means of income to buy more toys .... Your a smart business man there Chris and it won't be long before you'll have a fleet of machinery working underneath you ... Great P.R for Volvo : )
Volvo gave Chris an all expenses paid vacation to South Korea a couple years ago to see their main manufacturing plants. He's basically their Volvo spokesman here on RUclips already. And he had far fewer subscribers then. Can only imagine what they have in store now that he's reached half a million subscribers. 😉
What about cost factor in overall usage,is the extra money spent on machine justify in long run of the machine to perform and save you money or wear and tear.curious,as always enlightening on subject 👍👍👍👍😎😎😎😎
My LS-53 had an accumulator to provide stable and consistent hydraulic pressure so that hydraulic actuated clutch controls were consistent in response.
Could potentially save a person thousands of dollars a year on the bottom line. That could mean the difference between a make it or break it year. Also looks like it's not overly complicated.
simple genius. I am wondering if it makes use of every gravity situation that utilizes hydraulic.. not just the boom? I learned accumulators with aircraft. little electric pump helpers so we did not have to start engines to move them around.
@@cmmartti Except that uses a rotary motor so now you need to come up with all the extra pieces for that. Not going to be worth that when there isn't a large fluid difference to gain.
I'm happy for the progress you are getting. You deserve to treat yourself with better performance unit. You work very hard to get that machine. Wish your very success in your patience to fulfill your dream
The term 'hybrid' is a bit of marketing hype. The hydraulic accumulator has been around since the 19th century. It's a great idea though storing that energy. If it does save 15% of fuel over time that'll help.
There are other ways to collect energy from the movement of the machine. Create your own energy to assist the operation of the equipment, like power generators when turning. Power could be harvested & generated with magnetic actions energy collection. Hybrid Volvo harvesting energy could change world to collect & create their own energy. Just make more than you use, is all the energy you need to create. Volvo has a history of forward reaching technology. Loved our Volvo Wagons. Would be perfect again. The Volvo Wagons are one of the best for smooth ride & dependability. Dad could fix our Volvo cars. Had a bunch of them, before he traveled his final journey. No Thumb? All excavators should have a thumb as standard equipment. Most excavators operators need thumb & bucket working together with off-set bucket teeth for fine work. Excavators need 350* articulating bucket & thumb on ball joint to be given better full movement. Operators need better coordination between controls, bucket & thumb working together. Which will be able to do fine detailed work would be an amazing transition in technology for excavators. Design a quick attachment for retrofitting excavators, working in cooperative partnerships. Three quick attaches. First quick attach articulated head to boom as a unit. Quick change to rock hammer, for instance. Back & forth, until you remove the rock you are working on. Chris LetsDig18 worked big rock removal with rock hammer excavator together. But, he spent weeks & months waiting to get the job done by other contractors being so busy. Being able to quick change between the bucket/thumb & a strong rock hammer, would have gotten the Animal Clinic done months earlier. No waiting on others. Having a strong articulating bucket & thumb would have made most every job even easier. To be able to change the position of the bucket & thumb, would work much better for logging with or without root removal. Wiggle this way & that way to get in cracks of the rock or pick up mixed directions of trees fallen in forestry. No more sloppy forestry grapple hook, see if tool will wiggle into place to attempt to grab a log. Give that grapple some control by the operator. Machine would get lot more work done. Not too hard to retrofit. It has some value, but would be an amazing grapple tool if forestry operator had control. I would bet operators can think of all kinds of equipment you might want to attach to an articulated ball head for more control to fine work. Being able to quick change different attachment. Maybe, you need two thumbs working together at many angles. It's very obvious why this is needed, when you watch excellent world class operators work in the field. They have to push, pull, shove, sideways, forward, reposition excavator, all kinds of wasted movement & time just to pick things up at angles. Every operator I have asked has agreed an articulated bucket & thumb would make time saver. Every operator shaving off unnecessary movements makes them even better world class operators. Volvo take a survey, I did. Thanks.
Someone or some company who buys this new, will hardly ever use this machine until its End of Life cycle is up. Which means this option wont even recoup the cost of depreciation over time, whether its 5 or 10 years, before they resell it. At 15% fuel savings a new machine depreciates faster year over year. This comment is absolutely NO KNOCK on LD18, or Volvo. I think the innovation and development is moving in the right direction, and I applaud Volvo and their fantastic machines for creating this. I just think the fuel saving needs to increase for the purchaser to combat depreciation, to make this a viable option How much more does this increase sticker value? Cheers, thanks for letting me debate this option. No hard feeling I hope
You can hear the difference in the engine/pump noise when there is a charge saved up lifting vs no charge. Good system
🤔 Obviously they want you to buy it.
OK. Now, ask them "Does it come with a 2-year front glass replacement warranty, with a no clauses attached". 😉
Haha 😂
😁
The savings in fuel will allow him to change windshield every 2 weeks. It's for free!
... but tinting the front windshield will end up costing him a fortune
They gave Chris the KEYS to the dealership. 😆
He took the golf cart out to the sandbox...and no one else is there! 😳
The hybrid sounds like a win! 👍
I'm a sceptic/careful. First thing I do is ignore the marketing and sales bullsh*t! and then see what happens in the real world with a day running in hybrid and a day with it off or maybe half the job one way then the other and measure the fuel used.

That track squeak must be Volvo trade mark.
They all do it unless you're in mud to publicat the tracks because you can't lub them. I think it drives everyone crazy 🤪
It’s weird watching you run a machine without a thumb.
Good catch.. didn't notice myself.
And with mirrors extended.
A thumb seams to be a US-thing mostly,looks more familiar without it for me. On the other hand - looks like something is missing without a Rototilt.
I'm glad they gave the option to turn it off. Cat tried this and it was a huge failure. The 336eh we had got about 40% less production. It felt like running a machine from 1000 miles away with dial up internet.

How does it store the energy?

@@gregfeldman6818 its basicly a hydraulic cylinder in itself. the piston just doent have a rod on it. the piston is also pressurized on the backside

🔥LOOKS LIKE A SOLID MACHINE 💪💪💪
That almost looks like a system that could be added to an existing unit.
I get the impression that's what they did when they created it.. made it as an ad on to an existing modle.
True though Doubt it highly, bumped to the 300, + the extra costs of making you buy it... If it was simply an addon kit they would lose out on extra $
Ain't you lucky over in Scotland we are paying £7.85 for a gallon of diesel which is equivalent to £1.55 per litre so the hybrid would be a good idea over here great work with the videos addictive watching 👍
Looks like a great unit, get out your check book!
Its a fast 30 ton machine for sure great video
It looks as if the accumulator supplies pressure to a motor mounted in tandem with the main engine drive so helps the engine turn the pump.
I like the idea of saving energy, my only thought is how long would it take to get your money's worth out of the difference in cost of that upgrade. At $45 quoted estimate, I think it would take many days to see a real savings in cost of the upgrade. It seems like the machine is more active.
My guess is you'd have to run it 50-60 hrs per week, year round to start saving $$$$. No way could you recoup it if the machine sat for weeks between jobs
That is the snappiest response on a system control I have ever seen. Damn.
You can lower the boon and lower the 💥! Now, all you need is jet engines, rockets and wings. Warp speed Capt!

But the real question is will you still be able to pick up a toothpick like you do with your old one!!! Your skills amaze me 👏👍💯
It sure looked to be a very stable machine. I'd like to see a size comparison to a 220 or a 250. Chris probably told them overseas he needed better fuel to hours percentage.
Over 15% fuel saving is a MAJOR improvement! Airlines would start wars for such fuel savings! 😁
It looks more like the hybrid system adds a hydraulic motor to the main hydraulic pump to add the torque to the engine from the accumulator.
Yea, looks like a fixed displacement piston motor!
Don’t you wonder who the Engineers are that develop the New Ideas to Reduce Operating Costs ?
Just arrived from space. That’s why they didn’t offer this 5 years ago. New technology.
It's hard to see but if you look under the R in hybrid @2:27 you will see it change.
Thanks! I couldn't find it at first.
Thank you! I was going crazy!
I gotta say, isn't it ironic that they've made a more eco-friendly tree killer! XD
What a great idea for a great machine! Best wishes.

Usually accumulators are used to speed up hydraulic systems - that is another advantage to it - more work done.
The little knowledge that I have about hydraulic accumulators is that they need to be checked regularly to be sure oil hasn't leaked into the air chamber.
Not a reason to buy a new excavator by itself, but if you are in the market for a new machine, it is certainly an option to consider.
At first I thought that machine would have a huge bank of batteries. No way
The savings sound great but...what is the extra cost of this Hybrid technology and how many years will it take to recover the extra costs. Does it make sense for an owner/operator?
Well, maybe your next excavator will be a hybrid one.

So when are you going to be a sales rep for Volvo , since you work 24-7 another means of income to buy more toys .... Your a smart business man there Chris and it won't be long before you'll have a fleet of machinery working underneath you ... Great P.R for Volvo : )
Volvo gave Chris an all expenses paid vacation to South Korea a couple years ago to see their main manufacturing plants. He's basically their Volvo spokesman here on RUclips already. And he had far fewer subscribers then. Can only imagine what they have in store now that he's reached half a million subscribers. 😉
THAT IS A GOOD LOOKING MACHINE. I DON'T KNOW IF YOU GOING TO BUY IT.
Volvo should give you model to play with.
A 950 ?
Congratulations Chris
What about cost factor in overall usage,is the extra money spent on machine justify in long run of the machine to perform and save you money or wear and tear.curious,as always enlightening on subject 👍👍👍👍😎😎😎😎
It would take a LOT of incremental costs for a 15% reduction in fuel use to not pay for itself.
My LS-53 had an accumulator to provide stable and consistent hydraulic pressure so that hydraulic actuated clutch controls were consistent in response.
sales man likes the word energy
engine has to *generate as much torque
Could potentially save a person thousands of dollars a year on the bottom line. That could mean the difference between a make it or break it year. Also looks like it's not overly complicated.
simple genius. I am wondering if it makes use of every gravity situation that utilizes hydraulic.. not just the boom? I learned accumulators with aircraft. little electric pump helpers so we did not have to start engines to move them around.
Probably only the boom as it's really the only item that gravity would assist.
@@cmmartti Except that uses a rotary motor so now you need to come up with all the extra pieces for that. Not going to be worth that when there isn't a large fluid difference to gain.
have you ever worked with a rotortilt attachment ? would be cool to see you playing with one
I'm happy for the progress you are getting. You deserve to treat yourself with better performance unit. You work very hard to get that machine. Wish your very success in your patience to fulfill your dream
What a clever solution! Why wasn’t this done decades ago? Doesn’t seem to have any brand new tech involved.
Chris; This machine would have been tops at the Animal Hospital with the rocks and stuff.
what an amazing machine, just beautiful
Not another soul in sight, everyone else is enjoying the day off while chris works.
That 15% of Gas depends on who's using the Machine. You got some people that takes them all day to do a Job.They need 200 Gal.
I was able to demo one for 40 hours, I'm going to buy one.
Awesome looking machine.
The term 'hybrid' is a bit of marketing hype. The hydraulic accumulator has been around since the 19th century. It's a great idea though storing that energy. If it does save 15% of fuel over time that'll help.
Impressive Thanks for sharing 👍
There are other ways to collect energy from the movement of the machine. Create your own energy to assist the operation of the equipment, like power generators when turning. Power could be harvested & generated with magnetic actions energy collection. Hybrid Volvo harvesting energy could change world to collect & create their own energy. Just make more than you use, is all the energy you need to create. Volvo has a history of forward reaching technology. Loved our Volvo Wagons. Would be perfect again. The Volvo Wagons are one of the best for smooth ride & dependability. Dad could fix our Volvo cars. Had a bunch of them, before he traveled his final journey.
No Thumb? All excavators should have a thumb as standard equipment. Most excavators operators need thumb & bucket working together with off-set bucket teeth for fine work. Excavators need 350* articulating bucket & thumb on ball joint to be given better full movement. Operators need better coordination between controls, bucket & thumb working together. Which will be able to do fine detailed work would be an amazing transition in technology for excavators.
Design a quick attachment for retrofitting excavators, working in cooperative partnerships. Three quick attaches. First quick attach articulated head to boom as a unit. Quick change to rock hammer, for instance. Back & forth, until you remove the rock you are working on. Chris LetsDig18 worked big rock removal with rock hammer excavator together. But, he spent weeks & months waiting to get the job done by other contractors being so busy. Being able to quick change between the bucket/thumb & a strong rock hammer, would have gotten the Animal Clinic done months earlier. No waiting on others.
Having a strong articulating bucket & thumb would have made most every job even easier. To be able to change the position of the bucket & thumb, would work much better for logging with or without root removal. Wiggle this way & that way to get in cracks of the rock or pick up mixed directions of trees fallen in forestry. No more sloppy forestry grapple hook, see if tool will wiggle into place to attempt to grab a log. Give that grapple some control by the operator. Machine would get lot more work done. Not too hard to retrofit. It has some value, but would be an amazing grapple tool if forestry operator had control.
I would bet operators can think of all kinds of equipment you might want to attach to an articulated ball head for more control to fine work. Being able to quick change different attachment. Maybe, you need two thumbs working together at many angles. It's very obvious why this is needed, when you watch excellent world class operators work in the field. They have to push, pull, shove, sideways, forward, reposition excavator, all kinds of wasted movement & time just to pick things up at angles. Every operator I have asked has agreed an articulated bucket & thumb would make time saver. Every operator shaving off unnecessary movements makes them even better world class operators. Volvo take a survey, I did. Thanks.
LOOK 👀 13:MINUTE MARK...PLANET X IN THE SKY @ 11:OCLOCK LOCATION ABOVE THE MACHINE ! 🤣🤣🤣😂💯🥁✌🇺🇸
This system has been around. Guy in Sweden sold this system in the 90s to Cat but they screwed him over and never put it in production
Someone or some company who buys this new, will hardly ever use this machine until its End of Life cycle is up. Which means this option wont even recoup the cost of depreciation over time, whether its 5 or 10 years, before they resell it. At 15% fuel savings a new machine depreciates faster year over year.
This comment is absolutely NO KNOCK on LD18, or Volvo. I think the innovation and development is moving in the right direction, and I applaud Volvo and their fantastic machines for creating this.
I just think the fuel saving needs to increase for the purchaser to combat depreciation, to make this a viable option
How much more does this increase sticker value?
Cheers, thanks for letting me debate this option. No hard feeling I hope
Can’t tell any difference except the fuel ⛽️ usage 😁
