Just so you know, if you get and HL760 receiver you can connect it to the CR700 through its radio and have it mirror what the CR700 is seeing. This can be great to put in the cab with you or for when you are sighting the laser height.
Really appreciate this teaching. I was unable to understand how you use two grades on the laser and receiver to crown the road. I do see how the primary grade 4% and 17 % was established. But, I don’t think you necessarily need to use the laser to crown the drive way other than maintaining less than 17%. Guess to put it more simply, did you use the dual slope feature of the laser system? Thank you!
We did use the dual grade feature. The culvert has a minimum and maximum required coverage and was installed to follow the same grade of the road for proper drainage while maintaining an even coverage and smooth transition. Had we not used the dual grade, the upper end of the driveway would have come off level with that part of the road, but then the lower side of the driveway would have been too high or humped. We set the road grade on the laser, and then programmed in that 4% grade perpendicular to the road, which allowed us to transition off of a sloped road while maintaining the minimum grade requirements and creating a smooth transition.
Dual slope means that you can set a slope for the x axis and another slope for the y axis. In this case he set the y axis to match the road’s slope and the x axis to match the allowable approach, perpendicular to the road. He didn’t discuss crowning the road, ie making the middle of the driveway higher to shed water.
It will need some maintenance, as with any driveway in the mountains, but we cut it back quite a bit to allow for room to slough off so it should taper over time.
The walls were cleaned up a bit for the finished driveway. They are still pretty clean cut, but the soils out here are very hard decomposed granite, so they’re pretty solid to begin with. This was done two years ago. Coincidentally, we are actually out on that property as we speak working on the foundation for the new home build, and everything looks great! Overtime some stuff may slough off, but that’s why we made it extra wide to allow for that to happen naturally.
That there was some SERIOUS earth moved! I have no idea what my max is in Kern Co. CA, someone told me what it was but I forgot. I won't have a driveway nearly that long, but it is a fairly steep slope (15% my guess) with a left bend half way up. We're not allowed to leave it just dug up, will require a retaining wall.
Nice video! Quick question about the y axis for the culvert install. Can you move the machines magnetic receiver up on the stick of the ex and catch the same grade of the road but at a lower point (bottom of the culvert)
Thanks for the comment! To answer your question, yes, we do that when installing culverts. When you set either the x or y-axis, depending on which one runs parallel with your culvert, you can then set a benchmark on the centerline of your culvert and then adjust your laser receiver to whatever depth you need to clear the culvert and the required coverage on top. Example, we do a lot of 18" culverts, so we typically set our receiver (on a grade rod, or on the stick of the excavator) so that we are digging approx. 26" below grade along the culvert centerline. If the axis on the laser is set to, say, +/- 5%, then digging along that axis will give you the +/-5% no matter what depth.
The laser gives a line for your grade for rise, but how does it show you run so you know you are right? I have one of these and need to dig in a drain, but haven’t got the process straight yet
The laser is set to a percentage which is the relationship of the rise and run. Example: A 2% grade is 2' of rise for every 100' of run. For a drain, if you want 2%, set up the laser with either the x or y axis parallel to drain. Set that axis at 2% or -2% depending on orientation. At the starting point of your drain, set the receiver on the grade rod. Now, you should be able to check that you have the desired slope along the drain. Hope this helps
Loved. Thank you for nice explanation. I got coming demo house and dig 650 yards and I want just make this digging one man operation I just see this gl622n . Thanks for links. You got new subscriber.
Would you recommend this laser for digging basements, culverts, concrete site prep, crawl spaces, sewer lines etc…? Or which laser setup would you suggest?
Hey Troy, Looking at picking up on of the gl622n kits. I was curious if there is a reason you went with the cr700 receiver vs one of the LR models that have a larger laser pickup area(Lr-20,Lr-30,Lr-50,Lr-60)? Have you been disappointed with the small receiver area, or would you still recommend? It is my understanding that the CR700 does not have a plumb indicator, do you notice there being a place for this in your operation, or is it not really necessary in your opinion? Thanks!!
99% of the time, we use the cr700 on our CAT 304 mini ex and/or on my custom dozer blade mast for our CAT 259D3. I feel it worked fine for the larger excavator for this project. Obviously, the larger detectors with plumb indicator, plumb compensation, etc would probably be even better. We'll probably invest in one of those one of these days, but for our "bread and butter" workload which seems to be residential foundations and septic systems here in the CO mountains, the CR700 has been a GREAT addition. Well worth the $$$. Probably paid for itself during the first job - not needing a ditch hand to stand there all day checking grade with a rod...
@@troyloftus4840 Troy, thanks for the response, i'll pick up the package up under your amazon link. Just curious, did you maintain your 8% slope from the main road, once you switched to the 17% grade going up the driveway, or did you flatten out? What is your recommendation on how far up a drive you go until you rotate your Y axis to a more level drive? Thanks, and Happy Thanksgiving
After cutting-in the first 20' perpendicular to the road, I abandoned the 8% slope of the road. It is really personal preference after the county requirements are met. The max is 17% in our county after the first 20', and we usually put a 2-4% slope back against the hill (horizontally) as we go up the drive. It keeps the runoff against the hill which helps create/maintain a ditch. We try to get away from the 17% as soon as we can to a more manageable 10-12%. Obviously, less slope is better, but also have to balance how deep you cut, how much material you are willing to move, etc...
È un buon lavoro considerando l'uso di un ricevitore base come il cr 700 con assenza di piombo... Lo usiamo anche noi per lavori simili e scavi per condotte. A mio avviso però il 17% è troppo... Anche per il fatto metereologo... La pioggia rischia di trasportarti tutta la ghiaia a valle ...
The two eco-freaks who down-voted this video already have their houses in the Colorado hills but don't want anyone else to have that opportunity. They are crying over that young pine tree that was dug up with the first excavator scoop. He most likely replanted that pine.
I think your communication would be more effective if you didn’t use the word “basically” so frequently. It’s unnecessary and distracting. Otherwise, good video and thanks for the info.
This is the most educational video from an operator on the spectra! Thanks for sharing
Thanks so much! Appreciate the kind words. We’ll have to do some more the next time we have it out!

Nice video, now I can visualize whats meant by x and y axis slope
High speed! You definitely know what your doing. Thanks for the video, that was very informative.
Glad it was helpful!
Great video!!! I need more!!

That is exactly what he showed - match grade of the road and the driveway at 4% perpendicular from the road.
@@dpatru Only the Y axis can match a grade, the X axis establishes whatever the plane is from the Y axis.
So...What are they going to do about the wall from the driveway cut? Any type of erosion control?
It will need some maintenance, as with any driveway in the mountains, but we cut it back quite a bit to allow for room to slough off so it should taper over time.
What will be done to ensure those banks don’t erode and fall in?
The walls were cleaned up a bit for the finished driveway. They are still pretty clean cut, but the soils out here are very hard decomposed granite, so they’re pretty solid to begin with.

Hi, quick question after you set the 4% fall why did you adjust the receiver? Should you not keep it in the same place?
Once I set the 4%, I can then adjust/set the receiver to whatever point I want to start the 4% from.
Fantastic Job! Congrats
Would you recommend this laser for digging basements, culverts, concrete site prep, crawl spaces, sewer lines etc…? Or which laser setup would you suggest?
Definitely. We use it daily for all of those things. We will probably pick up an identical setup for an additional crew this season.
Great video, I learned some good stuff here.
