- Q: the proper name of it?
- The tools look similar but a scaler is thicker on the ends and has sharper edges to clean (scale) the teeth. Hope this answers your questions!!
- Q: In a project, 5 excavators need to be used. The probability of a single excavator malfunctioning is 0.0594. And their operational functioning is independent from each other.1. Which variable should be formulated as discrete random variable?2. What is the probability that exactly 2 excavators will be malfunctioning?3. What is the probability that there are less than 3 excavators malfunctioning?4.Give 2 reasons why independency assumption might be violated?Anyone please be kind enough to clear my ignorance in the above questions. I am happy to thank you in advance
- 1. x, for the number of excavators malfunctioning, takes on the values 0,1,2,3,4,5 p = .0594 q = 1 - p = .9406 2.. P(x=2) = 5C2* p^2 * q^3 = .02936 3. P(x<3) = P(0)+P(1)+P(2) = .73625+ .23248+ .02936 = .99809 4.Think of a reason where the malfunction of one causes problems for the others.
- Q: I have a big dirt pile just sitting behind my fence on my property. We plan on knocking the fence down and re-building it so the dirt pile needs to go as its in our way. The dirt pile came from a ditch that was built next to my house months ago and the workers just left the dirt that was dug up on my property. I have been calling and calling the company to come clean up their mess and they never return my phone calls so now I have to get rid of it myself but how? My husband tried shoveling it and spreading it out but that is way to much work as the pile is big and rock hard from sitting for so long. I have also called equipment rental places to rent a bulldozer or excavator and push it all out but they are way to expensive (we are on a budget). What's a cost friendly way to get rid of unwanted dirt piles?

- Q: For the longest time, my 4 y/o has called construction barricades quot;investigaugesquot;. Is he trying to say something else but pronouncing it incorrectly? Something learned from Bob the Builder or the like? I can't correct him if he's onto something I'm unaware of.
- Maybe he's trying to say excavations? My 3 year old calls Special Agent Oso on Playhouse Disney Investigation Oso.

The main technical parameters (diesel version): weight: 724t maximum power 3000kW (4082 horsepower) bucket capacity: 38m3 BUCYREUS 595 BUCYREUS 595 595B in 1999, it may be caused by the evolution of Marion and 351M, the main arm length is 18.3m. The main technical parameters (595B): 1179t: the quality of the installed capacity of bucket capacity: 64.3m3 BE BIG: BIGMUSKIE MUSKIE BE BIG MUSKIE BE products, the official number is BE-4250W, is by far the largest step dragline, 1967 BE started as an open pit coal mine America built it, until the completion of May 1969 and put into use, the cost of manufacturing was $25 million, specifically for debris peeling. It has 22 stories high, with 13800V high-voltage power, the bucket weight of 209T; 91 years, BigMuskie mined out due to decommissioning, 99 years blasting demolition, only bucket retained.

- Q: What are the advantages and disadvantages of wheeled excavators and crawler excavators?
- This is mainly focused on the chassisCaterpillar: advantage: the ground area, so in the mud, wetlands and other easy to get into a good place, because the excavator itself weight, so that the excavator can go more widely, another crawler is a metal products, qualified in the mines or bad conditions can also place, off-road ability the production of low cost, small investment.Disadvantages: another is mobility is not good, the highest design speed of only 5-7KM/H, long distance dependent mobile vehicleWheeled: advantages: small investment, quick action, the average speed can reach 40-50KM/HDisadvantages: narrow range of use, mostly road or city works, can not enter the mines or muddy areas, poor climbing capacity, high production costs, large investmentSo now most of the excavators are tracked
- Q: What are the main features of buying second-hand excavators?
- In fact, if you are an expert, you don't need to see too much at all. Just look at the four. Instead, people who are not experts see it that way. Many friends say that second-hand excavators should pay attention to what?. As a matter of fact, there are so many and so many, not many. But individuals still suggest that if you are not an expert, bring an expert. Otherwise, you can't buy a good car. Do you want to worry about it?. Or buy a bad car to go back. In fact, the main thing to buy a second-hand excavator is to look at your funds. Do not think that two mobile phones are worthless, and always remember, a price, a sub - goods. If you can try to buy to buy a private private, if you want to go to the market to see if you can choose Shanghai Jincheng second-hand excavator market. Let's not say how the car, at least compare credibility. Some of my buddies are going there to buy it. I hope these words can help you.
- Q: Can anyone help me with a circuit diagram for the ECU in a Hitachi tracked excavator/digger model EX100-5. Or does anyone know of any online forums where I could get any information at all? I'd appreciate it if you could help me.
- I type this out 3 and 4 times a day, I wish people would write it down. You can pull up your vehicle and print out what ever you want to repair.
- Q: How to change tracks on bobcat excavator 435?
- Down the side of the track frame there will be a small access panel! There should be a grease nipple inside! Unscrew the nipple and take it off! Then push the idler wheel inwards with the bucket of the machine! The idler is the one without teeth! This should close the wheel enough to put the track back on! Once the track is back on lift that side of the machine with the bucket and replace the grease nipple then just pump up the track with a grease gun!
- Q: how about Metro Excavator Bucket
