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.

Q:I forgot the name, it has a big claw, and grabs dirt who knows the name for it?
Its either a excavator or a wheel laoder, depending on what you mean .
Q:I have a Shih Tzu who's a little over a year old now and he's extremely athletic, no health problems, he's up to date on everything, but he's losing weight to the point where I can feel his hip bones, not a lot but I can tell. I live on a farm so he chases the goats and rides the excavator, four wheeler, etc. He runs all day is my point, and he runs so much that it's becoming difficult to keep his weight up with his normal dog food. I use pedigree for adults if that helps. Now I've been mixing an egg in with it because he seems to not want to eat a lot. He will, but not much. He eats whatever else there is though, so I'm pretty sure he's just sick of the normal food he gets. Is there anything I can mix up for him that's healthy and will still keep his weight up? I don't want him to become underweight. Thank you! :)

Q:Who discovered the tomb of King Tut-Ankh-Amun?
fake. Christianity stems from a mix of Judaism and Greek Orphism in particular. There are some parrallels between the lives of Orpheus and Jesus, and Orphism replace into partly prompted by way of Egyptian theology because of fact it replace into stepped forward to a huge degree on Crete it quite is why there are some similarities to Horus. additionally comes from the geographical proximity of the two cultures and the probability of them sharing a straight forward delusion base, yet in actuality it quite is not actual.

Q:I live in a condo complex. Four years ago there was an irrigation problem in front of my unit because my sidewalk was uneven. When it rained water would collect and cover the sidewalk. The board members at the time decided to cut corners and rather than raise the sidewalk, they simply punched 2-3quot; diameter holes in the cement (12 of them in a span of 10-15 feet!)...and now...there is no dirt under the sidewalk and when we have a good rain, water runs out from underneath the sidewalk and there's a moderate sized 'stream' that flows toward my porch. This stream has eroded ALL the soil from in front of my porch and I've lost several bushes because of it and my porch bricks are crumbling from the water damage. What type of contractor do I call to break up the old sidewalk, fill in the missing dirt and build a new sidewalk? What type of contractor would have the knowledge to fix this? A general contractor? Concrete guys? Landscapers? Plumber/excavators? Please help...
