Shanghai Engineering Machinery Plant Co., Ltd.

　　Founded in 1921, Shanghai Engineering Machinery Plant Co., Ltd. is the earliest enterprise in China to develop piling machinery products. It specializes in the design, manufacture, and sales of underground foundation construction machinery, primarily providing equipment and integrated construction solutions for large and mega-scale projects such as high-rise buildings, subways, bridges and ports, expressways, airports, marine engineering, water conservancy and hydropower. The company's main products include TRD method machines, fully hydraulic crawler-type and walking-type piling frames, multi-axis diaphragm wall drilling rigs, twin-wheel deep mixing drilling rigs, static drilling and planted pile method drilling rigs, DCM treatment systems, multi-functional casing auger drilling rigs, diesel hammers, electric-driven vibratory hammers, hydraulic hammers, micro-pipe jacking drilling rigs, etc. Shanggong Machinery adheres to the business philosophy of "Professional Service, Creating Value," continuously promoting technological progress and quality improvement of piling machinery products, and enjoys high visibility and brand influence in the industry.

　　The company's products have won numerous awards. The Jinling brand piling machines have repeatedly been awarded the titles of Shanghai Famous Brand Product and Shanghai Famous Trademark. The D-series super-large cross-section ductile iron tubular diesel pile hammers won the third prize of Shanghai Science and Technology Progress Award in 2006. The TRD-D method machine, with "Research and Application of Complete Equipment and Technology for Ultra-deep Equal-thickness Cement-soil Mixing Walls," won the first prize of Shanghai Science and Technology Progress Award in 2016 and the second prize of the National Science and Technology Progress Award in 2017, respectively. A cumulative total of projects including the JB160A walking pile frame, ZLD180/85-3-M2-CS underground diaphragm wall drilling machine, D220 super-large tonnage tubular diesel hammer, DCM treatment system, SDP static drilling and root-planted drilling rig, and TRD-D method machine have been recognized as Shanghai High-tech Achievement Transformation Projects. Additionally, the company holds 38 authorized patents, including 19 invention patents and 19 utility model patents, as well as 2 software copyrights.

　　With the overall development strategy of focusing on underground foundation construction machinery and achieving product differentiation, the company has established a technological innovation system with its R&D department as the main body, market-oriented, and integrating industry, academia, and research. Aiming at industrialization, it promotes the transformation of scientific and technological achievements, independent innovation, and the cultivation of technological innovation talents, developing a batch of new-generation underground foundation construction equipment with independent intellectual property rights, strong core competitiveness, and high technological content.
