Founded in 1997, China Caigong Construction Machinery Co., Ltd. is a high-tech China vacuum excavator manufacturer and wholesaler specialized in manufacturing and exporting construction machinery and make design, manufacture, sale, and installation of the high operation working construction equipment. With CE, GOST (Russia) and ISO certificate, we also obtained China Certification (CCC) and ISO9000 international System of the Quality Certification to ensure the quality and service of our used pallets products. Our customize vacuum excavators products have been widely used for transportation for both men and cargo in field of general buildings, but also industry, electric power, miming, oil, chemical industry etc.

The present invention is an improved vacuum excavation system for use in the excavation of earth, waste, or other materials. A liftable and pivotable slurry or spoils tank and vacuum system are mounted on a mobile base. If required, a fluid source may be used to loosen earth or hard-packed material that may be drawn into the tank by the vacuum system. The slurry tank includes a manifold system that may receive air or other fluid to agitate the slurry or spoils to facilitate the release of solids from the tank. An exit port is provided in the tank to allow controlled release of the slurry. A valve means is utilized to allow for the use of a pump or air moving system wherein flow may be directed alternatively between the vacuum function to draw a slurry stream into the tank and a pressurizing function wherein air or other fluid is forced into the tank through the manifold system.

We offer the best optional dry filtration package available. While everyone offers the same blowers, engines and accessories, Vector has included the little things that others missed. This makes our systems safer, easier to use and more dependable. We did not just jump into the excavation market. Vector let others blaze the trail. Our water pumps come with clutches so they do not run continuously. Our machine shuts down automatically only when fully filled, rather than when ? filled. Our tailgate is easier to open and the internals will not rust out. Our trailers do not crack. Our machines do not have exposed belts or water pumps. Also, we are contractor driven, so we have avoided the features that “sound good” but do not work in the real world job-site.
