Diesel Locomotive / Tractor

  
   Shandong Dongda Construction Machinery Co., Ltd. continues to increase investment in the science and technology research to innovate and develop products, relying on the rail transport business for many years. Our company independently innovates the roadrailer based on the market research.
   Shunting operations and marshalling used to be completed by traditional locomotives or hoisting machine in small and medium-sized freight yard and railway lines, which not only increases the logistics costs, but also affects the transport efficiency for the vast majority of factories and mining enterprises. Our company boldly puts forward technology cross-border, and creates self-designed "roadrailer". It achieves a major breakthrough in four major systems: the power, walking, hydraulic and gas circuit. The roadrailer enhances shunting efficiency and solves grouping problems to the small railway freight yard. The technology has been granted more than ten national patents. Three patents have entered the trial stage: track automatic dehumidification system, frame flexible links and exhaust gas filter device. The domestic initiative product fills the blank of domestic low-speed and large tonnage cargo tractor. There are no relevant technical standards and alternative products in our country. According to the "Product Quality Law", the company has drafted the technical standard of the enterprise product and successfully filed the certificate in the national enterprise standard network. The product has obtained the ISO-9001 international quality management system certification certificate.
   After the roadrailer being put into the market, its efficiency, energy-saving, amphibious switching characteristics are widely recognized. Our company won the bids on many major projects like Beibu Gulf Port Authority. "People's Railway News" has repeatedly reported our company and our products. With the national "The Belt and Road" development strategy, the roadrailer is successfully pushed to the ASEAN market and exported to North America, Chile. With the gradual improvement of the product, our company expands cooperation with the enterprises which belong to the railway system, like Qingdao Quartet Locomotive & Rolling Stock Co., Ltd and Meishan Vehicle Co., Ltd. And signs cooperation agreements them. Our products serve as economic traction power, and can directly supply for the railway system through the two companies. In order to increase the development potential of enterprises, the company increases investment and cooperation in technology, personnel, funds and other areas achieving strong combination with the integration of social resources. Our company intends to authorize the patented technology license to domestic large-scale machinery manufacturing enterprises, playing their advantages of equipment manufacturing to expand production capacity. Our company has set up R & D in Qingdao, relying on the advantages and leading role of China's high-speed rail base to strengthen cooperation with research institutions. Our company has invested more than 2,000 million yuan, to build the 6,000 square feet new workshop, to buy 7 new machines and equipments, and 16 sets of special testing equipment.
  The company will continue to strengthen the this "three major advantages": "quality, service, cost-effective". Our company intends to build the nationally first-class manufacturing and service brand of roadrailer. And gradually develop into the scientific and technological innovation-oriented enterprise that set the R & D, manufacturing, service of roadrailer as one.
