The company was approved by Jiangsu Department of Science and Technology to establish the provincial engineering research center in 2010, and was approved by Xuzhou Economic and Information Commission to establish the municipal enterprise engineering center in 2011. The R&D center, consisting of product development division, engineering division, process technology center and test center, is the platform for innovation. Through years of research, the company has made a breakthrough of the key technology in the field of coal mine hoisting and transportation protection equipment, producing some high-tech products of independent innovation with 7 authorized invention patents and 12 utility model patents.
Depending on our own R&D capability and EUI (enterprise-university-institute) cooperation, the company is in the forefront of domestic counterparts in the technology innovation and has developed the world’s first rope-changing vehicle. The innovation of rope-changing vehicle and the linear continuous rope-retraction and rope-releasing technology have reached the international advanced level, filling the gap of domestic market. The @TT rope-choosing and rope-adjusting intelligent protection device, originated by Sansen, enables such capabilities as adjustment of double side conveyances, rope-sliding prevention and rope-clamping to avoid the rope-slip or winch-slip accident. It is applicable to hoisting system maintenance adjustment and rope-sliding prevention. The ZHT-B type rotary & automatic deck-changing swing deck with double-adjustment locking system, originated by Sansen, enables a stable bidirectional compensation to lock the cage reliably, reaching the international advanced level and forcing the price of foreign similar products to reduce in half.
The R&D center has successively undertaken more than twenty technology programs including two state torch plans, one state SMEs technology innovation fund, one “Four Kinds of Projects” of safety and technology, and gained over ten provincial science and technology awards. Thereinto, “Safety Protection Technology and Equipment for Vertical Shaft Hoisting” won the first prize of Scientific and Technological Achievement of Safety Production by the State Administration of Work Safety, “HLB Type Manipulator Rope-catching Rope-sliding Prevention Device” won the first prize of Technology Progress Award for Coal Mine Safe Production in Jiangsu Province. The emergence of technical innovations has boosted the development of the company.
