Product Description:

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:Is the excavator a motor vehicle?
A motor vehicle is a wheeled vehicle that is powered or driven by a power unit, which travels on the road for people to ride or is used for carrying articles and for carrying out special projects.

Q:do u have to have a lisence to operate an excavator or skid stear?
Yes. If you use such equipment without one, you are liable for prosecution.
Q:MTG - Ally Mill Question?
Five Allies are coming into play. Each will trigger their own ability, and each will trigger off the others as well, so each of them is triggering five times. In addition, the original Excavator triggers five times (assuming it's the same player controlling both the Excavator and the Rite). So you have six Excavators, each triggering five times, for a total of 30 triggers. When each resolves (assuming nothing happens to any of them in between), they count six Allies and mill six cards, for a total of 180 cards milled. Twincasting the Rite is a little different (obviously). When the Twincast resolves, it makes a copy of the Rtie. The copy resolves and all the above happens - 180 cards milled. Then the original Rite resolves and five more Excavators come into play. So now you have eleven Excavators, each triggering five times, each milling eleven cards, for 605 cards milled. So you get a grand total of 785 cards milled if my math is right. Which, frankly, seems like just a teensy bit of overkill.
