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.

Product specifications:

• Gear-rack crowding, powerful penetration, high efficiency;

• Gear transmission uses gears with a high hardness surface for durability;

• Adopts planet reducer for swing and propel mechanism;

• High hand drive is adopted for durability;

• Air release spring disk brakes.

Q:How long does it take to learn how to start an excavator? Do you learn it in two months?
Do you have a license to the site is still not, for example, digging sand digging stone dug up are not the same, you will not say that several actions on behalf of you learned, I began to think so, but slowly you will know. Excavator is very good, very leisurely every day, my master another excavator hired a child, a day to do 3 hours, finished home, and earn a lot of money, you say money, good money do not earn?. Learn nothing with a quick mind. Although I am 17, I have studied repairing mobile phones, repairing computers, digging machines and forklift trucks. I think I am the best excavator, because those things I have a quick attitude. I am fat, the weather is very hot, the site conditions are very difficult, the sun is very poisonous, no pay, there will be no return. Come on, I believe your brother, you will learn very well.
Q:Attentions of excavator operation
Three. Travel on soft groundExcavators in the swamp, flood and other soft ground work, should first use the bucket to try whether the ground can withstand the weight of excavators. If you forget the process, there may be serious consequences unless you are driving an amphibious excavator. Although the excavator is tracked design, contact the ground area is large, but the excavator into the mud, can not move events also occur! Just note that this can be avoided. In the swamp, flood and other soft ground work, to avoid excavators trapped, should pay attention to these: 1, first with the bucket test. 2, do not stay long in the same place. 3, go straight, turn less.Wetland excavatorIn case the excavator gets stuck in the mud, don't worry. Never try to climb out of a climbing system. That will only get you deeper and deeper. There are many ways to save. 1, if it's not deep enough, try to hollow out the two tracks. 2, if it is not, on the first try, how deep mud, if not very deep, directly to the front of the silt layer, for their own way, slowly toward the shore near the hard ground. 3, if it is infinitely deep silt, can rent a few piece of iron or board, sideways pressure to the track below, you can easily out.Four, vision blind areaThe driver's cab is on the left, the middle of the passive arm blocks the view, so there is a large blind spot on the right, especially in the rear of the right. Many excavator accidents are caused by falling or dying of the right side of the tail! So in the not very wide field work, try to let the excavator on the left, the right to set aside more space.Excavator rearview mirrorRearview mirror in the excavator is a very fragile things, often in work or transport in the touch off, many drivers will feel touched, it is not important, it is not in time to replace the new rear-view mirror. In fact, the rearview mirror is very important in excavators, especially on the right side. Accidents are often due to a lack of safety awareness!
