I don't know much about the stuff but it is showing up with most of the big contractors in our area.It seems there is a certain minimum size of area that the stuff is economical to work in.
I don't think that GPS equipped excavators will ever really catch on. If all you have is cab display and not setup for machine control, what's the point? For a lot less money and better accuracy you're better off with a laser system.Now GPS dozers, that's a different story. Much easier machine to utilize the GPS for machine control. Also better suited for the optimum use of GPS, which is moving and placing bulk material as efficiently as possible. It will get you within .05' easy enough. If you need it closer than that you need a man on the ground checking grade with a stick anyway.We were the first ones with GPS in our area 5 or 6 years ago. I thought it would really catch on but so far we are still the only ones with it.
Excavator gpsHey pushcat.Must say i disagree with you on the matter of gps in excavators.Using gps on a pipeline you can see profiles of the trenc,you can put in changes in direction,and add some dept if you put gravel under the pipes.You know where to dig and how far down it is.Digging for a parking area you know corners and how deep you have to go.System tells you where the bucket is and the distance to top surface.I Think gps is working great on excavators too.Makes the work go smooth :my2c
Is those pictures the same machine or two different systems.They look different.Just wondering ??????If different which one do you like the best.:usa
Here in Michigan there are several drainage contractors switching over to full GPS grade control and surveying and doing away with lasers. I should be getting my new system in a couple weeks. Should speed up layout and installation time dramatically.As far as use on excavators, I think that will be available around here soon. I could see a lot of potential in that too if installing pipe or cleaning/digging ditches.
I do the drainage thing also,but usually more then enough slope here where i work ,just use laser for the bottom ground.Plus to old for the expense of GPS,maybe some day if i last that long.Post some pictures of your machine with the GPS on it sometime.You using a plow to install your systems?I would like to see more drainage trenchers and drainage plow pictures on here.Need to start a new thread with them i guess:beatsme:usa
Two systemsConstruct'O said:Is those pictures the same machine or two different systems.They look different.Just wondering ??????If different which one do you like the best.:usaClick to expand...I,m not 100% about the first one but i do belive that is Catepillars accugrade system. Only used that in a dozer (D8T) and that seemed okay to me.But i know some of the users of Accugrade have complained about the operating system beeing to complicated to understand.Accugrade is a new system so it will be better by time i think.Second picture is of an English system called Prolec.Very good system and easy to operate with i think.Had a volvo ec 180 with that system on it and it worked great.Support on it was a non team and that was:Banghead:BangheadMost sold system in Norway is made in Denmark by Scanlaser.Best support and if you have a problem you get the help you need:exactly

The guess work and rework has been eliminated completely, so the units have already payed for themselves. We have an excavator and dozer on site with GPS which eliminates all surveying.
GPS SystemI've had GPS Systems on my Dozers, Scrapers and Box Scrapers for several years. I love having the GPS system on the machines, They paid for them selves in one year, if not the first job. Last year I put a GPS systems on my excavators. I was worried at first, but It is the best thing I have done. They make the work so much easier, faster, and more accurate. You can do the same job with less help and time waiting for some one to lay it out. Most better contractors have gone to GPS systems, GPS Systems have absolute Lasers. Anyone that is doing any major contract jobs can not afford to be with out a GPS System. I think in a couple years you will be forced to have a GPS System because a lot of surveying companies are going that way, They do not have to go out and stake a job and restake a job when the stakes get lost. That is another good thing about GPS System, you don't have to worry about some one knocking over a grade stake, or the laser or transit getting run over. Also when you are done you have a record of what was done on the job.

I agree, us drainage contractors are a limited number. I'm a member of the Michigan Land Improvement Contractors of America and most of our members are drainage contractors.I used to use a Fiat-Allis HD 21 with a Link 250 plow, till I blew the motor. Now I am using a Bron 450 Plow, until my new Bron comes in.I have been using sub-meter WAAS GPS to map all of my tile/drainage systems since 1998. If you are now doing that, you should at least try it. Saves tons of time, and impresses the customer. Not to mention, it's easier to locate in the future.

I'd missed your first posts, but saw this one. GPS definitely seems the way to go for tiling applications!
GPS vs LaserI realize you guys are strickly talking about GPS units, but what do you think of the use of lasers for residential and light commercial excavating. I am toying with the idea of putting a magnetic receiver on the dipper stick of our excavator. In particular, does it actually save time..Thanks
Anybody have any links to GPS suppliers for excavators?

My First GPS system on the dozer was replaced last year because it was obsolete. So be careful when you buy that you are buying the latest system, and from a dealer that has is good with GPS systems.

I am doing a job on the Willamette river in Oregon and phase 2 requires us to remove 30,000 cy of material that is underwater! They want it to be to grade and I hope I can find a GPS system whose senors are water proof. Any info you could give me would be greatly appreciated
Our first GPS experience was about 6 years ago. Bought one system (indicate only) and set it up to use on a blade or dozer. Took about a year to figure out how to best utilize it. By that time, it was obsolete. Then we wanted to automate it on the dozer (figured out it made the most $$ for us there). To do this, the 1 year old system was obsolete, so we bought a new system, fully automatic for a D-6R. We got really god with it, doing with two machines and no groung man what used to take 4 machines and a ground man, and production still nearly doubled. Next we added a D-8T with Cat Accugrade, which is Trimble, same as our others, and production went up even more. Year and a half ago added a fully automatic system to our grader to replace the original indicate only system. On that job, 180 acres to sheet grade with 0.05' tollerance, we used the D-8 to rough in and the blade to finish, and got up to 10 acres per day. Now the oldest indicate only system is on the compactor in the fill, so things do not get overbuilt too much. I would not like to go back to the old way. No stakes to run over, plans follow you on screen in the machine.Sure, sometimes you loose satelite reception, but even if this averaged out to 1 hour per day, you still get double or more production than without. If the signal goes out, go grade a haul road or something till the signal comes back. Just don't finish anything, or you will probably have to do it over when the signal comes back.The key to making it work is a good 3D model. Find someone to build the models who has field experience, then he understands how it actually needs built.I am looking forward to a job that will justify an excavator system. Thats the next step forward for us. Mass excavation is easier if the excavator digs right to grade, never undercuts a slope, never leaves too much for the finish crew either.It is getting hard to compete without the production you can bid with a GPS system. Its a steep learning curve, but worthwhile in the end.
For you excavator guys, locally there are a few guys using the Ocala system. The really like it. You can use a magnetic mount laser indicator with it to reset grade. (otherwise, each time you move you have to reset on grade again)I know they are working on GPS control for excavators, but don't know much about it.http://www.ocalainstruments.com/
The GPS system I am getting on my tile plow is from AGPS.http://www.agpsinc.com/It is a stand alone system that can be mounted on any machine. (Cat is equipping their dozers with Trimble I think)They have several software packages for different applications.If you have any questions, call Nate Cook (listed on the site) , He is a tech guy for them and has set up systems to do just about anything.

Trimble makes a system for an excavator that once you set it you don't have to do another thing. It is a true GPS system not just a laser system that you are referring to The trimble system is a little pricey but worth the money.

They are water proof enough to stand rain and mine have been under water for short periods of time. I guess you should call Trimble and ask them.

The Trimble system is made for each type of machine and I don't see how a system for a dozer would work right for an excavator. My excavator systems have so many more sensors and is completely different than my dozer or scraper systems.Cat and John Deere uses Trimble on their machines. I have been around several other systems and think Trimble is the best, so that and the fact that Cat and John Deere uses them I went with Trimble.
Big Iron, Take a look at Topcon GPS Systems, they are very good about integrating their older stuff when they upgrade so your current equipment doesnt become obsolete. Also I believe their sensors are 100% waterproof, that was one of their selling points when we were looking at the system on their proving grounds. All in all good company with excellent support.
Also Cat dozers come pre plumbed for about any GPS system. Trimble/Accugrade is funded in a round about way by Cat. John Deere is doing a similar setup but does'nt have the same ties with Trimble/Accugrade. The other advantage to the Topcon setup is that the control box/screen the operator sees will read GPS, Millimeter GPS, laser, sonar without having to add anything. Just my experience with both systems, comments welcome.
Thanks for the info, I'll take a look at both systems. Sure hope one of them will do the job as I don't think my surveyors will appreciate being handed wet suits!
