Q:What do excavators do?

Excavators are also used in some special industries, such as rescue industryGenerally speaking, excavators are large machines that require a lot of earthwork in the task but can not be completed manually

Q::/I really wanna work at a place where i like.I really love anime/manga/video games.I wanna work somehwrere close by.Because i get homesick quite easier than other people.

Most places I know of, you need to be 14 to legally work. So, a job caring for the grounds would be something entirely appropriate for a young person. Mowing lawns, and so on.

Q:What can i do to keep the neighbors dogs from digging under the fence! They don't care!?

Put up some edging. If that doesn't work, pour hot pepper powder all over the area (you will have to refresh it daily) My neighbor ( the genius that he was) thought he would build a dog run up against our fence for some really nasty dogs. They would try to dig under and it scared my kids. I used the hot pepper and it worked. I also stood there a couple of times and beaned them on the nose. He finally moved the dogs.

Q:list 7 steps in parking a excavator

Q:The boom cylinders (2) of a 350D LC John Deere excavator have a bore diameter of 145 mm and a stroke of 1520mm. The hydraulic pressure of the system can be boosted up to 36.3 MPa when breaking hard ground or lifting wet sand or gravel. What is the maximum extending speed of both cylinders. Assume all the engine power of 202 kW is converted into hydraulic power.I got 0.17 m/s but wanted to make sure if thats right. If you can show the step by step method of solving this problem. I would greatly appreciate it.thank you.

The basic formula for hydraulic power is proportional to the force and the flow. We can calculate from the power to find time and so speed. This is: power_watts = (force_newtons x displacement_meters) / time_seconds We need the time so: time = (force * displacement) / power The pressure is due to the resistance to flow. Determine the force from the pressure and the cross sectional area of the cylinder, where one pascal is one newton per square meter. area = pi * r^2 = pi * 0.0725m^2 = 0.016513m^2 The pressure is 36.3MPa. The force is: Force = pressure * area = 599422N. The displacement is the stroke of 1.52m, so from the above formula for time: time = (599422N * 1.52m) / 202000W = 4.51s The extension speed (velocity) is: velocity = distance / time = 1.52m /4.51s = 0.337m/s Edited later: I missed the point there are 2 cylinders. As there are 2 cylinders for the same flow, the speed is half of one cylinder: 0.337 / 2 = 0.1685m/s <== Answer (as for your answer)

Q:I have a 2004 Chevy 1500 LS extended cab z71 package with the 5.3l. This truck has the towing package such as transmission cooler factory class five hitch and 87k miles and I believe 3.73 axle ratio. I'm wondering if I can tow a 7000lb excavator plus trailer on a short trip 10-15 miles with only one somewhat major grade. I'm planning on having to take it really easy on the truck but just curious if I should forget the idea all together.

It'll pull it. Use tow-haul and take it easy, but it'll do it.

Q:Which excavator is China's first rank?

If that is the joint venture brand sales, and sales of Komatsu Doosan is the best of the two, for domestic brands, 31 sales of the highest first joint venture brands: Caterpillar America brand, old brand, 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.
