In 2015, Yingtianxia series excavators developed by the company were fully listed and became the outstanding representative of high-end excavators in China. With its low power, low fuel consumption, large bucket capacity and high efficiency, the series excavators opened up a new space for energy efficiency of large and medium-sized excavators in the world.

Hardware Construction:

The company has invested more than 300 million yuan in construction funds, and built a new production line of large-tonnage excavators and a new fatigue test equipment for structural parts. The company has a complete machine test and test means; First equipped with high-end 3D design software, the implementation of network collaborative design, the realization of PDM technology database management, advanced hardware methods.

Input of talents and funds:

Company established a provincial enterprise technology center, recognized has a batch of 15 years experience in construction machinery industry product research and development of core technology backbone and management team of experts, bachelor degree or above technical staff accounted for 85%, the product research and development, production and management has a solid technology and mature management experience.

At the same time, the company pays attention to the introduction and training of professional technical personnel, has hired Japan, Germany and other countries construction machinery experts, to provide technical advice and guidance to the enterprise. Also, has selected a number of high-level technical management personnel studying abroad, by learning to master the world's leading science and technology, as soon as possible for the company, international engineering machinery manufacturers for the effective personnel training and reserves, so that the company can quickly into the regularization, the development of high speed rail.

The company has invested a lot of research and development funds every year, and cooperated with Zhejiang University to research 23 tons of hybrid hydraulic excavator, and jointly established the "Rexide Hydraulic Excavator Engineering Technology Research and Development Center" with Harbin Institute of Technology to study the material process and welding technology of structural parts. It cooperates with Shandong University to build the "provincial enterprise technology Center" and tackle the key issues of "hydraulic excavator muffler" noise reduction technology, cooperates with Linyi University to build the "engineering Research and development center", cooperates with Qingdao University to establish the product design and development base of hydraulic excavator, and is dedicated to the research and development of engine energy saving technology. Cooperate with Shandong University of Technology to optimize the strength performance of structural parts. A series of technical research and development strategic cooperation, so that large and medium-sized excavator new technology, new functions and new applications of the development of more technical achievements. The company's annual investment in research and development expenses account for more than 3% of enterprise sales revenue. It holds 40 patents.

Scientific and Technological Achievements and Honors:

As a national high-tech enterprise, Successively by the national and shandong province and relevant government departments awarded "shandong famous trademark", "the first in shandong province (sets) technology and equipment enterprises", "shandong industrial design competition silver medal", "the" 11th five-year plan "high-end equipment model enterprise in shandong mechanical industry" and "industry-university-institute cooperation innovation in shandong province outstanding contribution enterprise", "top 50 Chinese engineering machinery" honor.
