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.

- Q:i saw an add for this and thought it looked pretty cool but was wondering if anyone had experience ?is there a high impaction risk even though it is hardened?if so is there a substrate that would get the same look across without the risk?thanks!
- I have heard good and bad things about it. I use calcium sand, there is a very low risk of impaction. also white paper towels work. good luck
- Q:i put in a fake rock background and side walls too by the way its really nice so anyways the substrate is excavator its really neat. it is a sand substrate but when you mix it with water it hardens to a concrete like sand really low risk of impaction and just in case she does get impacted i give her warm baths with a massage 1 day a week and no signs of impaction so every time i take her out to hold her she poops when i give her baths not even when she hits the water yet she pooped but never in her enclosure please help but every day i do make sure she poops but i would really like her to poop without me having to take her out to poop before this setup she was on repti carpet and pooped without any problems please help and give ideas thanks

- Q:Can you explain the negligence in this situation:Company X hires contractors to build a new building. They do not the “call before you dig” regulation, which provides:Before commencing or engaging in any . . . excavation . . . each excavator shall provide notice [by phone] of the location and date of the planned excavation. Its purpose is to give the government time to mark gas/electric lines. When digging the contracting company hits a gas pipe the contractor flies and hits one of my employees who breaks his leg. My employee sues the contracting company ... will he win because of the negligence of the contractor to follow protocol?
- violation of a safety standard or procedure may be evidence of negligence, among other factors, provided the standard or rule was put in place to protect this type of victim from this type of harm. For instance, a fire lane outside a store is for emergency access by fire equipment. If you park in the fire lane and someone crashes into you, the fact that it's a fire land has NOTHING to do with either driver's negligence because there is no fire emergency and no fire apparatus involved.
