Hey guys , my work has been mainly centered around clearing g trees but lately the company I work for has been getting alot of auger jobs and I'm thinking I can make extra money by getting an auger attachment for my cat 320dl serial kgf00762 It os already plumbed for attachment and has a quick hitch , my question is how does it work 2 way ? Is it a physical switch or hydraulic setup to be able to turn the auger both ways?
thumb circuit works two ways. Beware heat when you get it going. I prefer letting motor loads to get dumped straight to the tank, but needing two way function means it has to go back through the valves both ways.
How exactly do you mean? It's just activated by a footswitch or am I missing something ?
Yes, if you got auxiliary plumbing out there on this stick there has to be either a switch or something. Most of the time it's switches on your control sticks. A trigger switch on the right. Maybe a trigger switch on the left. A thumb switch.
Only thing I have on my machine is a foot switch as well ad piping on the boom a d stick, just not sure how the two way works with an auger
For 2-way AUX hydraulic operation you would require a pliot system that uses two foot pedals, not one. It sounds as though your AUX is only 1-way flow.
Hey nige thanks for the input , so what would I need to install a 2 way flow ? Just the valves and lines to the block or would I need to do alot more ?
I think there might be more involved, including the boom/stick piping because with 1-way hydraulics one line is always a return with only low pressure. With 2-way hydraulics both lines can be high pressure depending on which way the oil is moving to the attachment. A quick look at the parts shows both medium and high pressure line arrangements for AUX hydraulics on both the boom and stick. Also a look in the sales brochure shows a slew of AUX options. i imagine what you have now is something like a single function circuit, what you need is a Tool Control setup. Maybe the TC setp could even be controlled using joystick-mounted push buttons.
No mechanic here but it sounds like your machine has just a one way hammer aux line. The tool control circuit provides for two way and more functions like Nige posted above and has buttons on the joysticks. I would like to add a hammer line to our MPG series 321DLCR but the plumbing and valves are expensive just for a one way line, the 2 way line will be more expensive. Might be cheaper to find another machine. Just for example I had the dealer add a 3rd medium pressure line on our next gen 325 in order to run rotating grapples or a processor and it was $14K and change on a brand new machine.
Would thetc circuit from a larger machine like a 345b work or should I really do like cm1995 says and look for another machine I do Thank you for the responses I'm learning as I go along . One other scenario I've seen is the use of the bucket circuit to control the auger ,I know it's time consuming but it gets the job done.
Yes I think this is my way to go , thanks for all the info
Bucket circuit might be an option but I think would be too high of flow. Could maybe use a flow control but that could create too much heat. Could talk to the dealer to figure out just what you have and the most cost effective solution.
Dealer down here charges almost 5 or 10 times normal prices, i kid you not, don't think we would use the auger so long for heat to be am issue, most times it's 1 or 2 holes 24in Dia 30ft depth . Thats like 1 hr max
If your drilling heavy soil like clay making the hyd's. work harderccould create a lot of heat in a short time.
So what are my options ? I already have a 1way valve installed ,it's either I go with a brand called digga based in Iowa or some Chinese thatbsay they have the 2 way kit . Either way my local cat dealer has been of no help
I'm not sure. You need to find someone with more hydraulic experience to help you figure out the best option.
I'm not a hydraulic expert, could a valve set-up be installed on the auger itself to reverse the one way supply to gain reverse flow? With solenoids and switch in cab.
This what the digga brand is telling me it can do
