A look at two 1980 Ingersoll-Rand DM45 Drillmaster's hard at work on a pattern. Like drilling and blasting? Then join today! PAmining is on Facebook: / 100046519906306 Follow the PA on Instagram: / pa_mining
Yup, they're made to rev like that, I think. From what I know, they were originally intended to be used for generator duty, but became so popular that they were used in everything from trucks, farm equipment, boats, to trains.
Trains have the EMD B I G brothers of the 53, 71, 92, 101 and on up series. They were in everything at one time and can still be found in military surplus.
Those older machines are something else to run. I learned how to run smaller hammer drills (ECM580) no leveling jacks the carriage is on a book arm you can move around, single man sit down cab. 6” holes and as memory serves a little faster than that drill, but it had a big drifter for its size. Could do up to 8”. Louder too on account of it being a hammer drill!
PAmining yeah the one I ran was all operator controlled, all by feel. As you get to the bigger machines now they’ve turned the operator into button pusher. A good operator will do better than any computer though. No matter how big the machine or what it’s doing a good operator (and this sounds corny but...) can hear the machine talk. Squeeze out even an extra minute per hole/seconds per cycle and save an hour a day without abusing the equipment.
I have been working on similar machines since 2005, but I have never seen such ones, it is too small, it's not enough to maintain a place. this DM 45 of what year?
Great video thanks brother. I can't eat half of what you just cooked. I can do the broccoli and the green pepper and that all. Keep up the great work see you in the next video
That was a GOOD one and the drill sounded a lot Detroit-ish! The drillers here use Furukawa drills. Company had to prove they'd crank in cold weather so they sent the drillers up to a big freezer to freeze the machines to show they'd start. They did. They have Cummins in them I think Thanks, Pal! A-PLUS! All my time was helping on air-tracks!
We looked at those Furukawa drills but the lack of parts availability and the lack of support in the area service kept us away from them. There's very few of them around here.
I know what you mean. Everything used to be track drills with swapped pairs like a Gardner/Denver drill and an Ingersoll compressor and vice versa. Never understood it but it paid the bills. I was just a helper but it still paid!
So I saw a o&k rh120e backhoe in Frostburg md there is also a cat 345b there as well you should go there in the future and take video docs of both of those machines
Interesting! I could learn a lot from that operator.
That engine is revving something unreal.....
Detroit Diesel. 2-cycle!

Yes, they are a lot more involved than modern drills. This is where operators learned how to drill by feel and not by gauges or computers.

I've always said that it's not necessarily the machine but ALWAYS who sits in the seat.
I used to work for IR and sell and train on this kind of stuff in the late 70’s early 80’s great company great engineering great days.
Love the videos! Keep em coming!
Thanks glad you enjoyed it!
nice to see old kit been used
nice shot inside thumb up

I did not know they made stuff like this I have the impact wrenches

What dictates when you will strip mine a coal seam Vs more common underground mining?
Mainly the depth and thickness of the seam.

PAmining, do you know what the largest operating dragline in the world is? I've looked, but am still not sure
Detroit power!

What exactly do you do for a living? Are you an operator or a technician?
Don't forget to film those documentaries about those big cats
Estas perforaciones, son para estudio de suelo ? No es para bajar banco ?
My guess is they're drilling holes to inject explosives to expose a coal seam since Justin mostly videos coal mining and equipment
Justin where are you out of? I feel like all this stuff is right near me.
I am out of Pennsylvania
I know I was wondering where. Im near Hamburg
