Product Description:
Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.
Main Product Features:
There are 3 pumps: the two main pumps are for supplying oil at high pressure (up to 5000 psi) for the arms, swing motor, track motors, and accessories, and the third is a lower pressure (700 psi) pump for Pilot Control.

- Q:Who can tell me about Doosan and Sunward Intelligent excavator which good? What are the advantages and disadvantages?
- Doosan used Korean goods, but also cheap, that is, bad quality, old and bad
- Q:I have a jd 490E excavator the boom function has very restricted hydraulic flow/power. I replaced the circuit release valve (two of them), which did not help at all.the problem was intermittent in the beginning, when boom control is used with stick control...quot;
- The swing arm drive has a separate pump system, ether the pump is bad or the control valves have an issue. Try the forum link below.
- Q:If I play three allies in the same turn, does each one trigger the other two allies' abilities twice? Are they placed in a specific order? For example:In my Main phase
- it does matter to what effect of the ally you want to trigger the most. for that order. halimar is played, mill 1 then hada, +1/+1 to hada, then mill 2 because of halimar then if bojuka is played, add +1/+1 to bojuka, then another +1/+1 to hada, then mill three for halimar. so a total of 6 cards milled by halimar, hada will now become 2/3 and bojuka is a 2/2 creature :)
- 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:I'm looking for a 2.5 tire for a sick hefty AM almost FR hardtail...(probably a Transition Vagrant)... I wanted something wide, predictable and that would really hook up on just about everything... I couldn't decide between the 2 tires so I'm thinking maybe Kenda in the rear, WTB in the front???
- I love the Weirwolfs....not too crazy about them on the front because they kick up crap all over my legs, but it's a great tire. I run it on the rear. A couple friends of mine didn't like the way they cornered because they said they could feel the bumpiness of the gaps in the corner knobs....I've never noticed it and they do great for me. Excavators are pretty aggressive....very different than the Weirwolf. If you have loamy or sandy/loose soil they'll hook up great. Kinda rough on the trails, though, so if you don't need the big knobs, maybe gear down a notch. Maxxis Highrollers or WTB Prowlers are worth looking at, and there are still a lot of people riding IRC Trailbears, too. Intense makes some great tires....definitely worth looking at.

- A B and C
- Q:How do excavators do?
- Well, that's a good question. If you want to know the answers that are in place, the answer is not mine. Here you are.. Don't ask who I am, nor ask me what I do. I'm just a legend!! Want to learn excavators, you must first determine whether you want to enter the industry, yes, in recent years, the industry is very popular, wages are very generous. Importantly, there will be a lot of money in return. Simply speaking, must be afraid of hardship, because most of the work conditions are relatively barren hills, wild mountains and the like, sparsely populated. Be tolerant of loneliness.
- 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:Would like to know how to choose excavator? From what considerations?
- well,If okorder
- Q:I need to know 7 different ways.
- Digging. je je. Some plants require a strong suplement of minerals for survive, if you see one of that, you are in a place that have that mineral. Of course this apply for iron Nq and some other single minerals, I don?t know about a plant that requires gold. Ho but if you are looking for calcium phosporus or something no mjetalic minerals, then this could be a usefull method You can use a matemnatical model, if you know that in some side are gold and in other side you also have that metal, the you can try to interpolate both sides fr see what do you have in the middle. The geologyst have some other metods, I think that they can identify the mineral oxide in the surface or througout the soil horizont. Also I saw once one of they using a sieve in a river, not for find gold but for identify the mountain composition, but i don?t know about that metods.
