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.

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 place
Q:When did excavators first come out?.
In the current social construction, excavators are becoming more and more integrated with our daily life. The excavator is the earliest human or animal power for digging deep river dredger, bucket capacity is generally not more than 0.2~O.3 cubic meters. The first excavator manual has been developed for more than 130 years of history, has experienced a gradual development process of automatic hydraulic excavator driven by steam rotary bucket excavator to the internal combustion engine and electric drive rotary excavator, application of mechatronics technology during the. 2012-4-15 22:37:57 upload download attachment (7.39, KB)American Otis 1833~1836, the design and manufacture of the first steam engine, composite structure, semi rotary, rail mounted single bucket excavator, productivity is 35 cubic meters per hour, but because of poor economy without application. The improved steam shovel was formally produced in 1870s and applied to strip stripping. In 1880, the first semi - rotary steam shovel with tractors as the chassis appeared.From the early twentieth Century to the late 40s, excavators entered the stage of diversification of power and walking equipment.In 1910, there was the first motor driven single bucket excavator;In 1912, there was a full rotary single bucket excavator driven by gasoline engines and kerosene engines;In 1916, a single bucket excavator powered by diesel generators was produced;In 1924, diesel direct drives began to be used on single bucket excavators; crawler walking devices were introduced in 1910. With the development of the automobile industry, the tire walking device is widely used in small excavator.In 30s, a walking device appeared.Due to the application of hydraulic technology, a suspension excavator equipped with hydraulic backhoe was installed in the tractor in 1940s.
Q:Where are the origins of the Carter excavator 320C? 15
Xuzhou is a manufacturer of China, as well as Japan and the United States
Q:How much weight can a excavator bear?
The main technical parameters (shovel): weight: 780t maximum power: 2 * 1400kW (3810 horsepower) 40m3 KOMATSU PC8000 KOMATSU bucket capacity: PC8000 PC8000 is the top model Komatsu excavator, diesel driven and electrically driven two forms, using two KOMATSUSDA16V160 (16 cylinder turbo diesel engine or 6600V high voltage) electric (motor power 2900kW) as power, fuel tank capacity 14000L. The main technical parameters (diesel version): weight: 724t maximum power 3000kW (4082 horsepower) bucket capacity: 38m3 BUCYREUS 595 BUCYREUS 595 595B in 1999, it may be caused by the evolution of Marion and 351M, the main arm length is 18.3m. The main technical parameters (595B): 1179t: the quality of the installed capacity of bucket capacity: 64.3m3 BE BIG: BIGMUSKIE MUSKIE BE BIG MUSKIE BE products, the official number is BE-4250W, is by far the largest step dragline, 1967 BE started as an open pit coal mine America built it, until the completion of May 1969 and put into use, the cost of manufacturing was $25 million, specifically for debris peeling. It has 22 stories high, with 13800V high-voltage power, the bucket weight of 209T; 91 years, BigMuskie mined out due to decommissioning, 99 years blasting demolition, only bucket retained. Main technical parameters: whole machine quality: 12258t, total power: 32500 horsepower, bucket capacity: 168m3 (295t)This answer is recommended by the questioner
Q:Lol new hero excavator dug holes and a drill ground is too disgusting,
Standing on the tunnel he dug, the tunnel would disappear and you would get 5 gold coins.

Q:How big is the digging bucket of Komatsu 200 excavator, what is its length, width and depth?
1, Komatsu 200 excavators digging bucket is generally 2.8 meters wide, bucket capacity in 0.8 to 0.91 parties.2, excavators, also known as mining machinery (excavating machinery), is dug with bucket above or below the machine surface material, and loaded into the transport vehicle or dump to the stacker of earthmoving machinery. 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:What is the difference between a loader and an excavator?
1, the loader is a widely used in earthwork construction machinery construction, highway, railway, electricity, ports, mines and other construction projects, it is mainly used for shovel of soil, sand, lime, coal and other bulk materials, can also be used as a mild shovel of ore and hard soil digging etc.. Different auxiliary working equipment can be changed, and the lifting, lifting and other materials such as wood handling can also be carried out. In the road, especially in the construction of high-grade highways, loaders are used for filling and excavating of subgrade engineering, aggregate and loading of asphalt mixture and cement concrete field. In addition, the soil can be pushed, flat ground and other mechanical traction operations. As the loader has the advantages of fast operation, high efficiency, good maneuverability and easy operation, it has become one of the main types of earthwork construction in the construction of the project.
Q:Heroic alliance AP excavator routine
First of all, the ghost book, and then fill CD shoes (combined with natural 40CD), hat method, stick to Central Asia, and finally can abyss, ice rod, Banshee and the like. Why is the price of the ghost book, the 80 method is worth 1600, 500 dollars in 20%cd and a passive enough value, if not the recommended if the vampire book with twin shadows CD completion.Play is not too aggressive early, CD long, and in addition to Q, there is no other skills, plus, unless a good opportunity to go in to control, do not easily go ahead.
