I want to add an auger to my new to me excavator, I was told the best way to go is to just have a mounting plate made to fit the auger that the local rental yard carries, then I can rent it for 60 bucks a day instead of buying as I wont often need it. The excavator has offset boom, so I was told by the previous owner to just instal a switch or a valve on the boom at the end of the lines that are for the offsetting boom, so I could switch the offset off and use my accessory, then switch back when finished drilling. Any advice on how to do this, I have an operator who can help with the mechanics, but I would like to have an idea of the best way to do this since he has never done this before either. What switch or valve should I use, or should I just use quick connects and unattach the hoses and hook on extensions out to the end of the stick? Thanks any advice is appreciated
why not just hang it off the end were your bucket goes and just use bucket control to spin the auger. on one pin it should hang straight
Any one have any pictures of this set up using the bucket controls and just hanging from quick connect?
I made up an adapter plate for my Kub 1.6 tonne What you have to consider is flow rate of the knuckle/offset boom circuit.
Would I be better off using the bucket curl/control circuit instead of the offset circuit? If the auger is freely hanging/swiveling on a pin, I shouldn't need to move it? But the downside is that if I ever wanted to add a brush cutter I wouldn't be able to use those hydraulics from the bucket control circuit, since I would need to be that circuit to be working for its original function.
What flow rate do you guess I will get out of the offset boom circuit? I though about it and this is how I want to go, mainly because if I add a thumb or brush cutter I will be plumbed for it.
I did some research and found out that the offset circuit should put out about 6.5, should be fine I think, the augers say 5-15? My question now is how do you plumb that, what valves do you use, I have been told you can do it with ball valves, but it seems you would need 4(two for the off set boom, 2 for the accessory circuit with 2 tees bringing them together. I would just switch one side off and on side on. I have also been told this is fairly easy to do with a electric activated diverter valve with a 12v switch in the cab? Or an I over complicating this and should I just use quick connects, and unplug the circuit each time, I really don't think I will be switching offset/accessory all that often? Thanks for the help, I am about ready to start getting this done
Another thing to think about is pressure, the offset circuit may well have a relief valve set at a low pressure because all it does is move the boom sideways. All in all you may be best of to plumb in an aux circuit. I do advise you to get the pressure checked to make sure your auger has some grunt. Pressure = power, flow rate = speed.
what do you think it would cost to have a mechanic plumb in an auxiliary circuit?
