Product Description:

We manufacture four types of 4m³ excavators, including WK-4A, WK-4B, WK-4C and WK-4D excavators. Our WK-4C excavators are the most advanced, and will gradually replace the WK-4A model. They are widely used in metallurgy and coal in middle and small opencast mines for excavating and stripping works, as well as in petroleum, chemical, hydropower, construction, and earth/stone work engineering.

 We have established a new production base in the Binhai New Area of Tianjin to facilitate the transportation and export of large-sized equipment. Our second wheel production line is currently under construction. We have also established production lines for wheels, axles and wheel sets for use at speeds above 200 km/h.

We are now turning our focus to international markets which we are certain can benefit from our high quality products and service. As we are constantly innovating and improving, we have no doubt that we will meet and even exceed our customers’ expectations.

 

We are the largest manufacturer of excavators in China. Since 1961, we have developed the first 4 m³ electric rope shovel with a standard dipper capacity of 4 m³ to 75 m³. We produce WK-4C, WK-8, WK-10B, WK-12, WK-20, WK-27, WK-35, WK-55 and WK-75 excavators, which utilize gear-rack crowding and AC VVVF technology. The world’s first and largest WK-75 mining excavator is now in operation in Xilin Haote, in Datang. Up to now, we have supplied more than 1300 excavators in China to gain more than 95% of market share in China. Our excavators are widely used in coal mines, metallurgical mines and ferro-metal mines. More than 27 of our excavators have been exported abroad, to locations such as India, Pakistan, Myanmar, Peru, Russia, Kazakhstan, Chile and South Africa.

Q:How many meters is the height of the PC-320 excavator?
PC78US-6NO machine parameters: weight: 6.85 tons bucket capacity: 0.28 cubic meters power (KW (PS) / whole height G:2.75 meters, upper frame width H:2.33 meters, climbing capacity: 35 degrees digging force: 38.8
Q:When was the excavator invented in that country?
The excavator is the earliest human or animal power for digging deep river dredger, bucket capacity is generally not more than 0.2 cubic meters of ~ O.3.From 1833 to 1836, the American Otis design and manufacture of the first steam engine, composite structure, semi rotary, rail mounted single bucket excavator, the productivity is 35 cubic meters / hour, but because of poor economy without application. The improved steam shovel was formally produced in 1870s and applied to strip stripping.
Q:Import Sumitomo A5-210 excavator fault code 0087 what does that mean? Is the engine system abnormal?
Plug the road, the big pump may plug, plugging the electronic pump, and there is a large pump into the East and West, and all kinds of blocking.
Q:What are the main parts of the excavator structure?
The common excavator structure includes power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities, etc.. These are the theoretical basis, I have learned in Henan, Zhumadian, mountains and rivers engineering machinery school! This school pays more attention to theoretical study! Lay a solid foundation for upgrading the technology!
Q:How much is Carter excavator 320D?
The full price of the joint venture machine is 115. There are two kinds of imports, one for 122 and 125 for one. Down payment 20 and tax. Insurance what, together with more than 30 W down payment, you can mention the car mortgage 2W5-3W per month. 3 years hope to help you, the quotation is not the same everywhere.
Q:LOL excavator correctly installed
Then, the choice of the color of the wild knife, the white punishment, no one does not use, not to discuss. The excavator belonged to the GANK and control pattern jungler instead of harvesting the juggernaut and werewolf like wild type or single red, so the single output bias challenge and singled punishment is not considered. The excavator has a W hit fly, with E drill dash and flash is controlled relatively stable, then slow down discipline to keep the W blue and strike with his teammates to keep people is very important, so in most cases is to upgrade the discipline of blue. If the early by anti wild miserable, poor development, need to quickly fill fill level under the condition of development, through the upgrading of discipline to speed up the efficiency of wild purple brush up grade can be considered, but not the most preferred purple punishment, because the Desolator excavator efficiency, improve the efficiency of punishment is not dependent on purple desolator.
Q:What is the special advantage of the romantic manor iron hoe?
The primary ore mine is hoe hoe, use it is the requirement of prestige class 1, grade 1. When the ore hoe dug star, you can upgrade to the iron ore or hoe excavator (model T800), because the excavator need only provide cinder can hang after mining, it is convenient to consider, must have advantages and disadvantages, so in the same condition, T800 can only dig the primary ore, and the iron hoe can be more than junior high dug mine, this is a fair difference.
Q:LOL, who controlled the new hero excavator?
This hero is annoying. When it comes to mobility and explosion, maybe a blind monk can fight!
Q:Use of excavators
(5) replacement of the devices can be poured, weight, installation, piling, rammed earth etc..
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.
