Core technologies are very different
The strength comes from professional and innovative technology, with 15 patents and 8 certifications.
The optimized design scheme has a strong impact. It is made of integrated components, with fewer accessories, fewer failures and easy repair and maintenance.
The use of new materials, high strength parts, more fatigue resistance, external use of wear-resistant high-strength steel plate, the durability and life of the whole machine further improved and extended.
Hard power of real manufacturers
The production base of Douchang Heavy Industry was established in Yantai, covering an area of 10000 square meters, with more than 100 employees, mainly engaged in the production of hydraulic products such as hydraulic breaking hammers, quick connectors, hydraulic shears, and hydraulic grab buckets.
The introduction of the world's advanced casting production line, machining production line and assembly testing production line has realized the full set of independent production of products and built a competitive high-end hydraulic system manufacturing and production base at home and abroad.
