Product Description:

WK series excavators are used for open-pit mines. They have been developed through a combination of years of successful experience in the manufacturing of mining shovels and the adoption of advanced technology in design, processing, and manufacturing from home and abroad. They are suitable both for stripping and excavating open-pit coal mines, iron mines and ferro-metal mines.

Our WK series excavators feature such state-of-the-art technology as three-dimensional imitation and definite circle analysis. They perform well and can be used effectively according to users’ requirements in combination with various haul trucks and crush stations for higher loading and lower production costs.

Our excavators’ electric system uses a rectifier/regeneration communal DC bus-bar and variable frequency speed adjustment system. The electric control, with PLC at its core, is a 3-stage system of up-position monitoring, field bus and frequency variable speed control. It causes not disturbance to the power grid, allowing a wider range of power voltage fluctuation and high power factor. The system is loaded with software to optimize the dig/cut curve and automatically optimize the hoist and dig power distribution. The system automatically troubleshoots, displays status, and calculates electric power. This system has the advantages of state-of-the-art technology, reliable operation, high transmission efficiency and low power consumption. Our WK-75 excavators are designed to be used in combination with mining trucks with a capacity over 363MT, and mobile crusher stations with a capacity over 9000t/h.

Technical characteristics:

• Gear-rack crowding, powerful penetration, highly efficient;

• Gear transmission uses gears of high hardness surface for durability;

• Uses a planet reducer for the swing and propel mechanism;

• Propel has a high hand drive for added durability;

• Air release spring disk brakes.

The improved steam shovel was formally produced in 1870s and applied to strip stripping.
Q:Excavator three oil one water refers to
According to the concept of construction machinery, good maintenance of FOWA can reduce the trouble of excavator about 70%F: fuel oilO: engine oilW: cooling waterA: airGeneral excavator 70% of the fault is due to poor maintenance

Q:Buying excavator loansI am 23 years old this year.
Fuel efficient and fast. Disadvantages: Volvo new machine can be, but domestic serious, more fragile, not enough thick, two mobile phone price is low, not good sell. Doosan: Korean brand, integrated more moderate, imported machines are low grade products, assembled. (DOOSAN) advantages: low price, low fuel consumption in -8 series. All kinds of projects are available. Disadvantages: the product quality is lower than the average price, moderate price, moderate quality, and poor after-sale. Low inflation. Hyundai: Korean brand, but it is low-end goods, assembled. (HYUNDAI) advantages: cheaper prices, good parts, cheap. Disadvantages: machines can't even reach the standard of domestic machines, either good or bad. Personal view: imported brands can only buy more than these brands, Keith (CASE), JCB (JCB), Kato (KATO), Terex (TEREX), Bohai Seoul (LIEBHER), Sumitomo (SUMITOMO), Ishikawa Shima (IHI), Kubota (KUBATO), Takeuchi (TAKEUCHI) are not allowed to buy. Low share, customer service service points less, difficult to buy accessories, if you buy, there will always be these problems. Komatsu and Carter are independent production brands, mainly considering the following domestic machines, relatively poor ability to import brands. But still divided.
