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 common 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-55 excavators are designed to be used in combination with mining trucks with a capacity of 220MT to 363MT.

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.

Q:What is the excavator handling system? Five
Excavator is divided into the car part, get off part, and work device part, get off is mainly the walking mechanism, the car is mainly controlled. The work device, as the name suggests, is the part that works. The excavator is the big arm, the small arm, the bucket, and some have the ripper. The main or hydraulic system, main pump, felling, pilot system etc..Excavator is divided into the car part, get off part, and work device part, get off is mainly the walking mechanism, the car is mainly controlled.

The main or hydraulic system, main pump, felling, pilot system etc..
Q:Excavator hydraulic oil how much?
In order to observe the glass tube for the middle, first of all to the standard excavator parked
Q:How about Kobelco 75 excavator
SK75 model is also good Isuzu engine (from Japan), the size of the arm, upper and lower frame (domestic manufacturers), machine production in Chengdu, Hangzhou in two placeA 75-8, price 550 thousand, the last 530 thousand to buy 5000 oil card to send, I am optimistic about his low fuel consumption 500 hours to 5000 hours for maintenance, hydraulic oil, other brands 250 maintenance is really two hundred and fifty, 2000 hours for hydraulic oil, change one yearRelatively large, the engine power is relatively small, 55 horsepower. Komatsu 70 is 0.37 party, 66 horsepower.
Q:Introduction of excavator
Excavator, also called excavating machinery, is a kind of earthmoving machine that uses bucket to excavate material that is higher than or lower than the machine surface and is loaded into transportation vehicle or unloaded to the stacker. Excavators are mainly made of soil, coal, sediment, and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operation weight (quality), engine power and bucket bucket capacity.
Q:Working principle of excavator running motor
Does the landlord complicate the simple problem?Principle is that the engine with a hydraulic pump in the transmission, walking motor in the drive gear drive chainSay so complex, who can understand?
Q:Where are the origins of the Carter excavator 320C? 15
Don't listen to the first floor of the CAT is the brand of the United States. But he is not produced in the United States in 3 countries around the world to produce a Chinese is a Japanese and a I don't remember.
Q:Card to bel 320d2gc hydraulic excavator how much money
The production of hydraulic excavators is also booming.Excavator hydraulic transmission is closely related, and its development is mainly based on the application of hydraulic technology. Its structure is mainly composed of engine, hydraulic system, working device, driving device and electrical control part, the excavator working conditions required to achieve the action is very complicated, so it puts forward higher requirements for the design of the hydraulic system, the hydraulic system of engineering machinery hydraulic system is the most complex. Therefore, the analysis and design of hydraulic system of excavator has become an important part of excavator.Single bucket hydraulic excavating machine is a mechanical equipment with periodic operation. It consists of three parts: working device, rotating device and walking device.
Q:Is the power supply voltage of the excavator AC or DC?
The motor and control system of the excavator is supplied.
Q:Which brand is good for excavator?
The man upstairs is detailed enough. Buy a brand car, those who have never heard of it, then buy parts are not good to buy,
Q:Do you have any proof of the ownership of the machine, like the car's pass?
Excavators do not belong to road vehicles, so there is no driving permit or driver's license. Only the special equipment inspection certificate issued by the safety management department and the operation certificate of the operators.
