Dunan Heavy Industry Represents Sharp Tools for Special Environmental Foundation Project Construction

A number of industry experts and scholars attended the press conference

"The research, development and application of the technology for complete casing cast-in-place piles, bite piles, and rock-socketed piles and complete sets of equipment developed by Dunan Heavy Industries and Cooperatives have reached the international advanced level. The bite piles have reached the international advanced level."

“Dong'an Heavy Industry successfully broke through the technological blockade of developed countries, established its own brand, made a great contribution to the domestic pile driver industry, changed the passive situation in which similar equipment relied on imports, and provided a powerful tool for domestic difficult engineering construction.”

Gu Guoqiang, Expert of Full Casing Construction from Taiwan

"The equipment is good or not, we only use it to know." Many old users showed great interest in the DTR3205H at the event site. The comments were not overwhelming. Obviously, the previous cooperation had strengthened their confidence in Dunan's heavy equipment. Among them, Qu Guoqiang's remarks from Taiwan's full-casing construction expert are undoubtedly more convincing.

Before and after 2009, Ruan Guoqiang came to Shanghai to visit relatives from Taiwan. During this period, with 35 years of experience in full-casing construction, he keenly discovered the huge potential of the mainland market and decided to stay in the mainland. However, at the time, there were no professional manufacturers in the country, and only a few of them were all imported, and the manufacturers of auxiliary parts were also mixed, and the construction staff were not professional. Therefore, the construction quality and efficiency were very unsatisfactory.

In January 2012, Dunan Heavy Industries Co., Ltd. immediately attracted his attention when launching a full-sleeve full-rotation drilling rig. In the four years since then, the development of Dunan Heavy Industry has brought shocking shocks to him. At the suggestion of Ruan Guoqiang, the company has purchased two DTR2005H and DTR2605 H equipments, and delivered a perfect answer sheet with excellent performance in the construction of multiple sites. Among them, DTR2605 H was successfully completed on Chenglan Expressway not long ago. He was deeply impressed by the construction of high pressure water-filled piles with a diameter of 1.5 meters, a pile depth of 120 meters, a depth of over 90 meters, and a pressure of 1 MPa.

“After more than four years of development and improvement, Dunan Heavy Industry has become a leader in the all-sleeve full-slewing drilling rig industry and succeeded in replacing imported equipment. We hope that in the future we will be able to further promote the rapid increase of domestic auxiliary parts for our special environment. The construction of the company will provide more guarantees.” Lou Guoqiang expressed the expectation of Dunan Heavy Industry on behalf of numerous users.

China Construction Machinery Business Network editors noticed that three customers signed a purchase agreement with Dunan Heavy Industry on the spot. “We need to use Dunan Heavy Industry equipment to acquire more wealth.”

According to Chen Jianhai , general manager of Dunan Heavy Industry, “R&D and service are the core driving force for Dunan Heavy Industry to lead the industry. Today, DTR3205H full-sleeve full-rotation drilling rig is listed on the Dunan Heavy Industry Co. , Ltd. , which also marks Dunan Heavy Industry's full-sleeve full-rotation drilling rig. Forming a full range of products, with the vision of creating a piling solution for special environments and mud-free pollution for users worldwide, Dunan Heavy Industries will continue to adhere to the common development with customers, work together for a win-win situation, and advance the construction machinery industry in China to a world-class level. ”

According to the editors of the China Construction Machinery Business Network, under the current background that the total sales of all-sleeve full-rotation drilling rigs are not more than 10 units a year, by the end of November 2015, Dunan Heavy Industry has cumulatively sold more than 30 full-sleeve full-rotation drilling rigs. Market share is almost 100%. The status of Dunan Heavy Industry in the industry is self-evident.
