    Diesel emissions in surface work environments

    Reel, I found out that our "best in class" brand of catalysts are MSHA listed, PA DEP and Norwegian Maritime Directorate certified, but as of yet not CARB certified. I am not sure if they are in the process of getting CARB certified, but I will be asking. With that said, let me ask you a...

    Diesel emissions in surface work environments

    Reel, I can tell you that the catalysts we use are expensive. I guess you would have to look at the whole picture and determine whether it is economically feasible for you to be able to use the applicable equipment, so that the return on investment is acceptable. These cats use precious metals...

    Diesel emissions in surface work environments

    To the Californians: Do the powers to be in California actually test the emissions, or do they require an emission tag attached to the engine stating the Tier of the engine itself? Could you use an exhaust catalyst installed as aftermarket to meet emission requirements? Like I stated in my...

    My old iron

    Funny you should mention the wheel covers. I removed them a couple days ago and am running the plain-jane steelies, more fitting to the truck I think. Ron, I think Studebaker was maybe a little to far ahead of their time in some respects. They used a steel bottom in the bed and double walled...

    Diesel emissions in surface work environments

    So the EPA actually comes up with the Tier specs then. MSHA does regulate and enforce underground diesel emissions (DPM, CO, NO2, etc.), although not in the same way as to determine what Tier equipment you can run. They use threshold limits of exposure for a certain number of hours per day...

    Wire welders

    I have used Miller, Lincoln and an old Union carbide MIG welder at the mines, all were good machines. I did a lot of research when I was looking for a 110v MIG for home. My searching led to MIller, Lincoln and Hobart brands as being good reliable machines. I settled on Hobart and have been a...

    My old iron

    Assuming the picture works, you are looking at my 53 Studebaker 2R5 pickup that I have been working on for almost 3 years... it takes that long to fix lots of rust, something you southern guys have no idea of. It is powered with a Ford 302, C6 trans and 9" rear axle. It is mostly stock other...

    please help. tools used to repair heavy equipment

    Here is my opinon. I have turned wrenches as an automotive technican, a millwright in an industrial environment, a heavy truck mechanic, and a mining heavy equipment mechanic, in addition to maintaining and restoring personal vehicles. Therefore I have bought many tools over the course of my...

    Diesel emissions in surface work environments

    I am curious, with all the emission talks for new vehicles, do they affect any of you guys working in surface environments such as general construction, road construction, surface quarries, and such. Specifically diesel emissions. I believe MSHA has jurisdiction over surface mines (quarries)...

    Are wheel loaders 4x4 or they are even better version of it?

    I had an Allamand compact loader-hoe that had hydrostatic drive. The rear axle was driven by a hydraulic motor, and with the flip of a switch, it had front wheel assist with seperate hydraulic motors at each front wheel. Problem was, both wheels drove off the same hydraulic circuit, so if you...

    What's your scariest moment on a backhoe?

    Once upon a time, I had an Allmand compact loader-backhoe. I loaded it on a short trailer without too much trouble, and only had to go 4 miles. All was good until I hit about 40 mph, when the trailer started swaying and throwing the rearend of the pickup all over. Fortunately I was able to get...

    Need info about fixing my outriggers

    Hey Nick, I would get a fine toothed flat file and gently run it over the gouges until you get the burrs down even with cylinder rod. If you leave it as is, you will damamge the packing in the gland and cause leaks. I wouldnt spend too much time worrying about the pits, getting the raised areas...

    3 pumps in a row

    tool_king, do you have an actual hydraulic shematic of the pilot circuit? revbill, The info last posted by tool_king does verify that it has a pilot gear pump which means somewhere there should be a relief valve. It could possibly be in the housing you have replaced, if that is the case you...

    Why no drillers

    Here are couple pictures of underground jumbos. They are either diesel tram-electric/hydraulic or full diesel self contained. Normally they are just a single rod for a hole dpeth of up to 15'. A specific pattern is drilled into the "face" then loaed with explosives and fired. Note the...

    Why no drillers

    My wifes sister had a three legged dog, but I think he is long since dead. Not sure if anyone would be interested in the bones of a three legged dog, so I better stick to drills.

    Why no drillers

    Here is the CPA1100 drilling a rock outcropping. This can drill up to a 4.5" hole to 25' deep with the optional mechanized single rod adder. It uses a hydraulic Montabert drifter, which I have also heard referred to as a "tophammer" in surface applications. It is controlled by a radio remote...

    Why no drillers

    I agree, would like to see a drilling section in the forum. I have spent many years working in underground mines, and now work for a mining equipment manufacturing company. We have recently offered a line of excavator mounted hydraulic drills to the construction industry. We also do Montabert...

    Do any of you do any type of drilling, what do you use?

    Hi MTIBill, I checked out your MTI website. I have only recently stumbled upon horizontal directional drilling and some of the techniques, rigs, and tools used. It is an interesting field for sure. Do you ever get calls for drilling apparatus for applications other than HDD? We manufacture...
