The double acting hollow hydraulic jack is a double-acting design, hydraulic reset, the design of the hollow plunger can be used for pulling force, but also for thrust. The advantages of the hollow hydraulic jack are: equipped with a safety valve to prevent damage caused by overpressure, and the painted surface makes the corrosion resistance better strong, all models include quick connectors and dust caps, equipped with dust rings to reduce pollution and extend the life of the jack.

Hollow hydraulic ram jack is connected with all the design features of single acting hydraulic jack and design superiority of double acting hydraulic jack, increase its operation and working speed, especially, it can make the best of its hydraulic force in the long stroke engineering.

The LCP20H-H hose-type concrete squeeze pressure pump for pumping mortar is designed on the basis of the squeeze hose pump. The pump uses high-pressure, wear-resistant steel wire reinforced concrete hose with a working pressure of up to 25 bar

Leadcrete is a Chinese company specializing in the production of grouting equipment. It contains grouting pump, grouting unit, grouting mixer and agitator, etc. Because people want to make full use of land space, the grouting unit for underground project is widely used.

Post tension hydraulic jack is mainly applied in group anchor stressing, pushing and lifting, and is widely used in post-tensioned large buildings and structures, prestressed concrete bridges and other great projects.

The mono single strand post tensioning jack is a multipurpose prestressed tensioning device, easy to operate. Mainly used for single hole tension. also used for porous preloaded, tensioning and troubleshooting, and can be applied to a variety of sizes of high strength steel wire and steel strand.

The invention of machinery is to liberate productivity. And the application of machinery has also made our work more efficient. Among them, wet shotcrete machine made in China is a strong explanation, because it has more powerful capabilities and cheaper prices.

The automatic grout recorder system is applied to curtain grouting, consolidation grouting, high pressure jet grouting, Karst grouting, GIN grouting, deep mixing cement pile, bridge prestressed grouting, highway maintenance grouting etc.
