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:Does the excavator include the off-site transportation of excavators?
Excluding off-site transportation, the Hebei is limited to this chapter in the major machinery, one safety, and off-site transportation charges
Q:trying to recharge A/C on 325C caterpillar excavator?
Rather than jumping the switch, you should be able to do it by floating the refrigerant canister in warm water. The heat will drive enough freon into the system to kick start the compressor. The water will get cold in a hurry that way, but if you keep changing it you can get the charge in pretty quickly. Jumping the low pressure switch can be hard on the compressor.
Q:How do i gain experience with heavy equipment operation?
IF you do not want to attend a certified school, (and I don't blame you) then your best option is to apply to the companies that do the type of work, get a spot as a laborer, and while you are in your interview, clarify what you want to do. (for yourself and for the company) Start out on the bottom, and find a mentor that will be willing to teach you, or get the company to send you to school. It is a great field to be in, so don't give up.
Q:what do you do to get someone elses stuff off your property?
id go to legal aide and see what court order you can take out for free. otherwise leave it on the verge and its your dads problem.but in the old days of yesteryear you need to understand that crossed races where shunned apon so your dad is set in his old ways.so the best bet is probably to get your daughter to move just until your dad takes his stuff. go on holiday so that no one gets hurt.take care.oh and if anything happens call the police as they will be able to assist you as your dad has made a verbal threat.
Q:What should I feed my Shih Tzu to help him gain weight?
I okorder.com/ You aren't likely to find good quality dog foods at your regular grocery store. Higher quality brands are sold in specialty pet stores and feed stores.
Q:What's the difference between Carter 320C excavator and 320D excavator? Where's the difference?
The cab is different, 320C arm long, bucket small, 320D arm short, bucket big
Q:Help pick my business name?
Please edit your posting. Include your last name, the area you are in (State, County, Town, and any nickname of the above). Is your area historic for any reason? Is there a river nearby or other point of interest? Let us have more to go on. For example, in Lyons County there is the High Desert tourist area. If you were there, I could recommend LHD: Long, Hard, and Deep. Actually, for more professionalism, I would take Lyons High Desert and come up with other things that have the initials of LHD. But you have the idea now.
Q:name for the band.......?
Hmmm. okorder.com that has thousands of them. There's also a random band name generator too, if you get desperate. Oh, and a good idea is to click the random article link on Wikipedia. Anyway, I hope you find a name for your band. I'm pretty much in the exact same situation right now, but I have a few choices.
Q:Does it take longer and more difficult to dig a foundation than to put up floors of a building. How about cost
Interesting question. Digging the hole for the foundation is much faster than putting up the floors. Using a house as an example, the excavator usually can dig the hole in a few hours. Then, one day to pour the footings for the foundation, another day to form and pour the walls (if using that type of foundation). If using block wall foundation, figure a few days. Now comes the framing. Depending on the size of the house, it will take anywhere from 1-3 days to frame in the first floor deck. Figure another 2-7 days to frame the first floor walls, depending on the crew size and complexity of the plan. Repeat for any additional floors and then roof. There is no way to give you a cost. You have not given any information, such as size and type of building, location, construction materials, etc. Hope this helps.
