Hybrid Dozer Ain't Half Bad

Posted February 10, 2010 7:30 AM

The introduction of the "world's first" heavy-grade hybrid dozer is a watershed moment in heavy construction equipment tech. After 10 years R&D resulting in more than 100 new patents, this advanced dozer has not only achieved a Clean Air Excellency Award from the US Environmental Protection Agency, it's at least as powerful as its fossil fuel burning forefather.

The preceding article is a "sneak peek" from Construction Tools & Equipment, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Construction Tools & Equipment today.

Interesting but about 30+ years behind the times.

Letourneau and a few other mining equipment manufactueres where building giant rubber tire payloaders, rubber tire dozers, excavators, and massive hauling trucks with diesel electric drive systems along time ago.

My official degree is as an Industrial Maintenance Technician. However my life travels and willingness to learn and read about everything that I have worked on or around that interests me has taken it far beyond that. I have a natural fascination with how things work including the physics, mechanics, and general application histories of how something came to be.

The reason I know a bit about mining equipment and it history is because I had a student co op job at a big coal mine near where I live. Being there as an electricians apprentice I had some good experience working around the giant diesel electric and the full electric drive systems the mine trucks, loaders, shovels, and drag lines used. From there I just read up on the history of how they came to be so that I would have a better understanding of how they work and where they came from.

you say you worked as an apprentice electrician, did you ever attain an electrical license of any sort?

the reason I ask this is because in an earlier post some weeks ago, you were bad mouthing electricians and the jobs they do.

did you learn this from experience?

I have 9 months apprenticeship experience as a mine electrician and 8 months apprenticeship as an industrial electrician although that could have expired years ago for all I know. As far as where that stands towards my ever getting a license it depends on what licence I was being required to get. For my line of work an electricians licence is not necessary being I don't do full system installations or do electrical work for commercial clients as my primary job or work. Although I have done private residential systems from the transformer in a number of times which is legal by my present qualifications. Should I ever go to work for a business and need to get a license I have been told that it would not be a problem. Presently being self employed I have no interest in spending money or wasting time to get pieces of paper that tell others I am qualified for something if I don't actually need them. I know what I can do and I also know what the correct and legal processes are to do my work as I stand and what limits I do have.

I wasn't bad mouthing all electricians. Just the bad ones who screw the customers for higher profits and do bad work. I will do that with any profession that has a high number of bad seeds in it. I did at one time actually work with a company that was paying off inspectors to get dangerously bad work passed though and that was enough for me.

Unfortunately in my line of work I have had too much first hand experience with those types to say they are a minority. Much of my work experience and application is somewhat specific toward finding other peoples design flaws, cut corners, and over sites whether they were deliberately done or not and then fixing them. Basically I repair things for a living and I see far too much bad workmanship performed in many fields not just electrical work.

Why the interest in me?

I agree that this is a good thing, but not nearly as new as those in the proper places in government and Caterpiller hierarchy would have us belive. When I was in Grade School we were taught that we only had one world and where we could save resources and clean things up it was better than otherwise.

As mentioned by TCMTech - this rough design has been around for 30 years - it used to be fueled by the will to save money (fuel), but now they call it GREEN and someone is mightier than all others by coming up with such a Green Idea and for ponying up the extra dollars to "pay for conserving energy". I don't know what accounts for the 100 patents they boast, but it surely is not the vehicle concept as the ones that same contractor uses are most likely based on the same concept. Most likely they have figured out how to wring a little more work out of every drop of fuel they burn - most certainly a worthy cause.

The true "wow factor" is that it is both economical and "green". Most things that make no economic sense at all are marketed as "green", then those that need a political boost get behind them and we all just spend too much to make ourselves feel better about ourselves. This $600,000 machine would not have sold if it did not pay for the extra cost of being "green" by saving enough fuel to pay for it in 2.5 years!

The true irony of it is that it will toil away burnging dead disosaurs (at a still alarming rate) all day long building runways for O'Hare field so the inefficient jetliners can scream down them burning dead dinosaurs at a STAGGERING rate. All for the convenience and profit of tree huggers all across the united states! If we would do business with those in our immediate vicinity, instead of globally, this machine would not have needed to be built in the first place...

By the way... No one said what the energy footprint was to build that $600,000 monstrosity. I know $600,000 would buy a much larger pile of steel than that machine is made up of. Did the purchaser truly need a new machine, or could he have done the job with a used machine? I find it hard to believe that there would be anyone that truly needs a new machine in that line of work right now...

That all being said it is just plain...

COOOOOOOOL - I wish I had one to play with!!!!!
