- Q:i do not have a pic of it. so i'll just describe. basically, it looks like a excavator, except the end of the extended 'hand' is not for digging, but is attached with a driller kind of thing. but it is not for drilling holes, to be exact, it usually break concrete roads/floors such that a new concrete surface can be built again. don't think it is called a excavator drill.
- is it this one its called uammer excavator
- Q:i passed my 360 test in nov 2002 but never took up the job at the time.i now want to get into this line of work but don't know if i will have to sit a full test or a refresher?
- nah it lasts forever
- Q:I have 3 Kubotas and have a 3500hd to tow the two 2 excavators, but I was wondering if my 1500 could handle about a 6,500lb front end loader with trailer? I have been wanting to get a few opinions so I figured I would ask here among other places. Thanks.
- The tractor is about all it can handle. Depending on the rear axle its around 6200 to 6800 lbs.
- Q:What does an operating engineer do?Would their salary be the same as a regular nuclear engineer?I only wanted to get a bachelors degree and nuclear engineering looked the most interesting to me, but then I found out that with a bachelors in nuclear engineering you can only be an operating engineer..
- .....sounds dangerous lol in regards to you question idk.
- Q:Crawler excavator would like to know the performance, price and maintenance of knowledge
- For more information on excavators and more information on other engineering machinery, such as: bulldozers, road rollers, cranes and concrete spraying machine information.
- Q:What brands do excavators have?
- Import brands: [USA] CAT (Carter), CASE (Keith)[Japan] KOMATSU (Komatsu), HITACHI (Hitachi), KATO (Kato), SUMITOMO (Sumitomo), KOBELCO (Shen Gang).[Korea] DAEWOO (Daewoo), HYUNDAI (Modern), SAMSUNG (Samsung).[Sweden] VOLVO (Volvo)Domestic brands: Xugong, Liugong, Sany, Xiamen, Yuchai etc..
- Q:A few months ago we had some excavation work done by a licensed and insured excavator in our back yard near the well about 15 feet or so. He removed a lot of ledge and tree stumps and buried them to level yard. With in a week we got a terrible odor and bacteria. We have treated the well twice and the bacteria keeps returning w/ awful smells and our water tests are all over the place. We had great drinking water prior to work done. Because the bacteria has returned once again the well may be damaged and we are looking into that now. If the well is damaged does his insurance cover our damages? How do we find out???
- His insurance should cover any damages he caused. However, you will need to show that he actually DID cause the damage, if it exists. Right now, all you have is the fact that your well seemed to go bad shortly after the excavation work was done. That's not sufficient proof. You will somehow need to show that his mechanical actions caused this situation. It won't be easy.
- Q:does it help cost that i dont need an electrician, i own the property already, and i have a cheap excavator? or are these just minor things?i'm extrememly new at this and Im trying to cut costs if possible. and are wood floors cheaper than having carpet put in? any answers to one or all of the questions are greatly appreciated!
- owning the lot already is a huge savings. doing some of the work yourself is extremely helpful at lowering the cost, your not paying for all the labor. if your going with a builder, you need to ask if its ok if you can do some things yourself, many wont let you. what you might have to do is be your own contractor, and subcontract out the excavating, like the person you know, but you would need to check with all of the codes and get up to date on how that all works, if you need any special license to do that. like with the electric, you can do it, if you have it inspected. you would be surprised at how much you can save just even doing the finishing work yourself, like cabinets, floors, lighting, hanging the doors, fixtures, installing the shower, toilets, etc. some builders will basically bring the house to drywall, building the shell, and you can do the rest. a friend of ours is helping on his house and he cut at least 60,000+ off his price. as far as wood being cheaper than carpet, i would say not. but it all depends on which you choose and who you have install it. if you do wood floors, you can do that yourself and will save huge, and its easy, unless you lay carpet professionally i wouldnt go there, its worth having that done..
- Q:...what the biggest tool you have at your house?
- An excavator. (You never said what type of tool!)
- Q:Is it true that as a miner you can get a lawyer for free in North Carolina?
- Not too easy for me: Constitutionally speaking, Miners cannot get attorneys for free because they are gainfully employed and therefore not indigent. Plus, they are too old.
