- Q:Which country makes the excavator the best?
- In 1904, Holt developed the first steam crawler bulldozer. In 1906, Holt developed the first natural gas tracked bulldozer. In 1915, the Allied forces used Holt's "Caterpillar" crawler bulldozer in World War i.. In 1925, the Holt manufacturing company merged with the C. L. Best bulldozer to form a Caterpillar bulldozer. In 1931, the first Diesel Sixty bulldozer from assembly line in Illinois East Peoria line, it is a bulldozer using a new type of efficient source of power. In 1940, the Caterpillar range now included motor graders, shovel graders, lift graders, terraces and electric generators. In 1942, the United States used Caterpillar's crawler bulldozers, motor graders, generators and special engines for M4 tanks during the war. In 1950, Caterpillar bulldozer was founded in the UK, the first of many overseas companies. The aim is to help manage foreign exchange shortages, customs duties, import controls, and provide better services to global customers. In 1953, 1931, the company set up an independent engine sales team to promote diesel engines to other equipment manufacturers. In 1953, the group was replaced by an independent sales and marketing division to better meet the needs of the vast numbers of engine customers. Engine sales now make up about 1/3 of the company's total sales and revenues. In 1963, Caterpillar and MITSUBISHI heavy industries established the first joint venture in the United States with some stake in the us. Caterpillar Mitsubishi Ltd began production in 1965 and has now been renamed the new Caterpillar Mitsubishi Ltd. It is now Japan's second largest producer of construction machinery and mining equipment. 1981-83 years, the global economic downturn spread to Caterpillar, the company paid a daily loss of $one million price. The company was forced to slash staff in case it was forced to do so.
- Q:I was recently digging a post hole and scraped my undergound electric cable. The post hole digger damaged the insulation and scraped one of the wires. It sparked a lot then started smoking. I still had power to all parts of my house. The wire was not cut in half. Only the casing was damaged. In fear of being charged by the power company to repare the damage, I simply filled in the hole. Can anyone tell me if I can expect the exposed wire underground to give me any problems?
- The white wire is the common or neutral wire anyway and should not be carrying any voltage. Being that it is only a foot deep it was obviously added after the house was built because even direct burial U/F cable should be 2' deep per the electrical code. It possibly is an irrigation control line or landscape ltg. power line which in that case it would be low voltage. I would tape it up and forget it as well.
- Q:Do you think Helen of Troy is a Hero? Why?thnks..im curious what you think b/c some agree and some disagree.
- No. Why would you think that she might be heroic? If she existed in reality, historians now believe that Troy did exist after many centuries in thinking that Troy was a historical myth, but there is no evidence that Helen of Troy ran off with Paris and started a 10 year long war as written in the Iliad. Even if everything written about her is true, remember the story is rife with Olympian Gods interacting with people, she did nothing at all which could be considered heroic. If the stories are true, she is a queen and wife, who ran off with a prince of another city/state and caused a horrific war. Nothing that was written about her describes any of her actions that we would consider to be heroic. She is famous in history as in well known, but she is not heroic. whale Well, I left the question as to the truth of the story of the Iliad up for debate, but archeologists have found the city of Troy itself.

- Q:I saw one that said quot;Don't get pushyquot;,quot;You push,you pay!quot;and simply, quot; DO NOT PUSH!quot;. Be specific in your answer besides quot;it can damage the dump bed,ectquot;
- To conserve weight dump beds are realtively thin sheet metal construction and will not resist pushing with earth-moving equipment loaders,dozer,compactors,shovels,excavat... trucks etc. without bending. The usual occassion for pushing(or pulling) is when the truck is stuck,hence necessitating considerable force to move it----which is enough force to cause misalignment of the dump hydraulics,and even the frame itself. Especially bottom dump trucks have this defficiency (more apt to get stuck while unloading) and so they very often have a Push Block at their rear to allow the force to be translated directly to the truck frame which often as not is reinforced for just such occassions. Push block is easily recognized: they are heavy steel structures welded to the rear usually allowing 2 to 3 feet distance to the truck structure proper--they resemble the push block seen on scrapers but smaller. Usually rear dumps afford little/no space for placement of push blocks. They have to be pulled when they get stuck(not that often with a skilled driver !) Rear dumps are apt to get stuck when loading more so than dumping---as it dumps it has to roll forward to escape the pile. Loading by means of large excavator/shovel creates overflow and piles accumulate at point of loading, when a rear dump becomes enmired in such occassions the excavator operator(if he knows his stuff) can carefully (!!) push on the load of material in the loaded bed of the filled truck so that the immediate deformation from the force is taken up in the piled material not the truck's metal surface/frame/hydraulics, and the boost thus gained can allow the trucks engine/transmission to drive clear of the loose material creating the problem. When this occurs the excavator operator is at fault for sloppy loading--he is required to keep the loading area clear of loose material !!!!
- Q:I want to consider digging a hole for the foundation of an addition with crawl space to my home. This hole would have to be at least 4 feet deep for the frost line and would have to be the perimeter of the addition so 40 or more feet depending on how big of an addition. My question is, what are my options for digging this monster hole?I know I can always do the shovel and pickax route. And I know I can rent a mini excavator for about $200 a day from stores. Does anyone have any other inexpensive ways or some creative ideas that I could use to make this job a little easier?
- Try rental places, but you will find costs of $500 a day for a backhoe to do the work with.
- Q:Caterpillar said Friday it was shifting production of small tractors and excavators from its Sagami, Japan plant to the United States.The world's leading construction equipment maker said it will build a new $200 million facility near...Toyota announced on February 8 it will move remaining production of its Highlander crossover sports utility vehicle from Japan to Indiana, creating 400 US jobs.
- They won't oppose it...they will take credit for it, since everything else they do fails. Republicans always lie and take credit for the good things they don't do. And they blame the Democrats for anything they do that fails. Just look at the Bush Administration. He utterly destroyed the world economy be refusing to regulate the banks. He allowed millions and millions of illegal Mexicans to cross the border for YEARS. Then when it got out of hand, he labeled them undocumented workers. War after war, terrorism, 9/11 all of it occurred when GOPS run the world like dictators. Evil.
- Q:What's the difference between backhoe and backhoe?
- Do you usually see at the construction site of the Carter machine is backhoe excavator shovel, very rare, similar to the ordinary loaders, backhoe bucket and arm are arranged in turn is a shovel...
