- Q:How Do I find year model for Komatsu Excavator?
- take model and serial number to a dealer or aftermarket parts dealer.maybe you could find it on the internet, but its probably easier to just have a human look up a part.
- Q:How do they ventilate subway tunnels when they are building them? Obviously they cant use just electric vehicles to create stations and tunnels. TBMs are electric but they must use excavators, loaders, etc when building stations beneath the surface. How do they ventilate these tunnels?
- There are several methods that have and are employed to make tunnels.1 Why do you feel it is obvious that electric machines cannot be used? Tunnels are the type of spaces with limited air that are ideal for the use of non polluting vehicles. Rather than say We have to make pollution, how can we move it somewhere else engineers have asked, How can we not pollute the air. Subways are electrically powered. Modern tunneling machines are probably the very largest electric vehicles.2 Some of the machines have their own power stations located outside of the tunnels and some of the machines will use a grid connection. In most pictures of tunneling you will notice either a conveyor belt or a railroad removing debris.Both of these are also easily electrified. Formerly shafts were sometimes run to the surface for removing debris. And this may continue to be a solution for ongoing operations. There is an island in the middle of the East River in NYC outside of the UN that was formed from tunneling debris for the #7 subway line.3

- Q:My buddy is a Heavy equipment operator. He runs excavators/back hoes..that type of thing. Monster dot com does not cater to this type of thing. Is there any descent websites for this type of thing out there?Thanks for any input.
- Have you tried this one? www.getheavyequipmentoperatorjobs...
- Q:our company is badly in need of bucket teeth, good quality,competitive price.
- I work part time as a heavy equipment operator for my families construction buisness and we have tried a couple buckets but we never had luck with them the only buckets we use now are hensley buckets.
- Q:Is it possible to mine copper without using fossil fuels?
- copper mining is no different than any other industrial operation. Primary mining equipment uses diesel fuel (haul trucks and excavators) and/or electricity (shovels and processing equipment--pumps, crushers, mills, conveyor belts, electrowinning). Many newer operations tend to no longer employ smelting, though smelting is still an important part of the global copper balance as a source of sulfuric acid required for heap leaching and general copper processing (copper sulfate). Some very clean and modernized legacy operations (Kennecott in Salt Lake) are great examples of a modern smelter--operated on a continuous basis for high efficiency (meaning CLEAN).
- Q:My neighbors are using my driveway to unload equipment into their backyard. The reason they are using my driveway is because their house blocks all of their backyard from the road so they are using my driveway to unload excavator and backhoe to dig up their backyard.My mom drove down the driveway this morning and they workers had their truck parked in our driveway. He moved it right away but I still think this is not very polite.I don't mind them using my driveway but no one has asked or said anything to me. I was wondering what I should do?I was thinking about making the owners sign a contract saying that they know they dont own the property that they are using but can use it as long as I say so.
- I think they should ask because if something gets damaged they will have to pay for it or if an injury occurs your homeowners will have to cover it they are trespassing unless its your city or town workers they need to ask.
- Q:Who knows all imported excavator brands?
- The following has covered all the mainstream brands Caterpillar: American brands, old brands, independent production. (CAT) advantages: adequate strength, durability, strength, and not bad. Disadvantages: high price, high fuel consumption, short arm, small work range. Especially mine type models, large fuel consumption, after-sales service in general. 20T model: reference price: CAT320DGC 97-100W 320D 110-115W Komatsu: Japanese brand, excavator industry leader, the total cost-effective, independent production. (KOMATSU) advantages: better strength, strong and durable, low fuel consumption, hydraulic pressure is its strong point, the overall coordination is good, the speed is very fast, not easy to bad, good hedge, used car good shot. Disadvantages: high prices, accessories expensive. (Note: because of the domestic market share is very high, deputy plant parts, so it is relatively cheap) 20t models: PC200-8 97-100W PC200-8 hybrid reference price (earth preferred fuel consumption is 30% less than the average car) 110-118W Hitachi: Japanese brands, excavator sales are also very large, generally also can be assembled. (HITACH) has the advantages of mechanical matching, hydraulic system, flexible action, general value, durability, cost, fuel consumption, power, price 3-5 million cheaper than Komatsu.
