WK excavators are large-scale excavators used in open-pit mining. These excavators were developed based upon experience accumulated from years of manufacturing mining shovels. They utilize the most advanced technology in design, processing, manufacturing and control from home and abroad. Furthermore, they are suitable both for stripping and excavating open-pit coal mines, iron mines and ferro-metal mines.
Our WK excavators boast state-of-art technology such as three-dimension imitation and definite circle analysis. They feature excellent performance and working dimensions and can be used in combination with various types of haul trucks and crush stations in order to better satisfy users’ requirements for higher loading and low production costs.
The excavators’ electric system features rectifier/regeneration to communal DC Bus-bar and variable frequency speed adjustment. The electric control, taking PLC as the core, is a 3-stage system of up-position monitoring, field bus and frequency variable speed control. They cause no disturbance to the power grid allowing a wider range of power voltage fluctuation and high power factor. Their systems are loaded with software which optimizes dig/cut curves and automatically optimizes hoist and dig power distribution. This system automatically troubleshoots, displays running status, and calculates electric power. Using state-of-the-art technology, this system is highly reliable, highly effective, and energy efficient.
Our WK -20A excavator is designed to be used in combination with mining trucks with a capacity of 154 MT to 220 MT.

- Besides the early damage, your own personal Q or W, AQQEQ is the maximum damage, but not across the stakes, fish can go E, go to arthorn E wall to block your teammates and so on.Keywords: interrupted displacement. W priority excavator is very high, to you on the displacement, the vast majority is interrupted, such as arthorn E, NAR jump (hit fly can't jump), Q E (crocodile fish, with two Q, NAR) the blind, the opposite confident run down. Some of the high-end, you can even make small displacement transfer these non police directly stay around you. The rest is to leave your anger entirely on the opposite side. Blue punishment, look at the situation before giving.Finally, say, as long as you avoid the eye, the opposite is human, not God, can not always be able to prevent you from coming, so that the speed of light escape. As long as it can escape smoothly, the displacement length of the excavator E is difficult to escape.GANK blue side, big frog, F4, stone jump out; GANK red side, on the road slightly, F4, down the frog jumped out. These eyes can hardly be seen. After cutting, it is the art of interrupting movement, and perfect output. If it doesn't die, it's not your problem.
- Q:I just accidentally put diesel fuel in the hydraulic oil reservoir of an excavator. Most of it drained out from the top because it was over flowing. That's how i noticed. If I could guess there is less than one gallon of diesel in there and it is a pretty big excavator so it has a big hydraulic tank. Just wondering if the pressure will cause the diesel to combust. It's a rental an I only need it for another hour or 2. Thanks
- When compressed, diesel fuel explodes.
- Q:I need to dig up about 400 cubic feet of earth from my backyard (we are moving a retaining wall), and doing it with a shovel doesn't sound very attractive. I can't get a Bobcat or an excavator to the backyard because we are on a hill, meaning 1) there are stairs leading to the backyard and 2) the passageway between the house and the fence is too narrow. So it needs to be some lightweight tool. I don't mind working in the backyard, just don't want to do it by hand.If no tools exist and we'll have to hire day laborers to shovel the soil, how much earth can 1 person reasonably shovel in an hour? We'll need this to estimate the cost.Thanks!!
- I would ask my self if moving a retaining wall was a good move as you live on a hill
- Q:I don't see what the difference is between the two of them.
- Track Hoe Excavator
- Q:What can dragline excavators do that bucket wheel excavators can't?
- it's up to your imagination creativity as a site engineer , everything is possible in situ , sometimes bucket is used to push broken down vehicles
- Q:obviously, i can't really get a yes or no answer on this,but what i'm actually looking for is, what proof is there that the trojan war could have possibly happened?so far i've got- Parry's experiment in regards to how the story was passed down- Ancient Historians (herodotus, [he spoke about wife stealing])- Archaeological evidence (they found a possible site of Troy)- I NEED MORE!!!!!! any other ideas, even if they are just your own stupid theories)
- Troy also is mentioned in Thucydides, The Peloponnesean War, book i. Of course, the fundamental problem is that the story does not get written down until about 400 years after it happened. Best estimates for the war are 1250 BCE; Homer lives in the 800s BCE, so there is a major time period in between. This is shown by some of the errors in Homer's account, for example, the claim that the Greeks and Trojans burned their dead on funeral pyres. In fact, much of what we know of Troy and other Achaean sites comes from grave shafts -- buried people. So, the Homeric accounts are distorted by time and include some invention. At the same time, Troy VI does have many of the characteristics of Troy as described, and Troy VIIb does show signs of destruction by fire. From Thucydides, we know Greek armies were not very competent at storming walled positions, so the possibility of a lengthy war of siege is quite real. Troy is mentioned in other Greek legends, and it could be that there is a fusion of accounts -- the earlier, greater Troy (Troy VI) gets transplanted into the story of the war (Troy VIIb). This kind of compression is common in such ancient accounts, including Genesis in the Bible, where long periods of time separate event and history. Other Achaean sites discovered include Mycenae, Sparta, and Pylos, all mentioned in the poem. There is a great deal of Cretan and Mycenaean art recovered, including some displayed in the New York Times about 35 years ago. You should be able to find books on this subject. Archaeological evidence from the other Achaean sites include large numbers of account tablets, suggesting that any war which did occur was more likely about trade rather than the hand of a woman.
