Shandong Luoxiang Automobile Manufacturing Co., Ltd. has emerged as a shining star in the trailer industry. Since its establishment in 2009, the company has rapidly risen to a significant position in the market. In just a few years, it has transformed from an obscure small factory into a renowned “dark horse” in the industry. The secret to its success lies in its unwavering commitment to innovation-driven development.

Technological R&D is the core source of Shandong Luoxiang’s competitive advantage. From its inception, the company has regarded innovation as the lifeline of its development, continuously increasing R&D investments. It has established long-term partnerships with over 10 universities and research institutions, including Tsinghua University, Tongji University, Shandong University of Technology, and Shandong Mechanical Design and Research Institute. Through deep integration of industry, academia, and research, the company has pooled wisdom and resources to tackle technical challenges and drive trailer technology upgrades. With more than 200 R&D personnel, the company has established the Luoxiang Automotive Research Institute, Shanghai R&D Center, and a postdoctoral workstation, covering an R&D building area of over 8,000 square meters and equipped with more than 1,000 sets of R&D equipment. To date, the company has completed over 200 R&D projects and obtained 123 national patents, forming a significant leading technological advantage in the industry.

In terms of product innovation, Shandong Luoxiang has achieved remarkable results. The company has independently developed more than 30 new products, including compressed garbage trucks, dump semi-trailers, specialized warehouse-grid transport vehicles, and gooseneck container transport vehicles, meeting the diverse transportation needs of different customers and industries. For example, the warehouse-grid transport semi-trailer features a unique design with shaped holes on the beams, enhancing torsional resistance, allowing for concentrated cargo loading, reducing weight, and extending the beam’s service life. The materials used for the web and key components are low-alloy high-strength special steel, meeting advanced domestic technical standards, with a tensile strength three times that of ordinary manganese steel, ensuring high strength and reliability. This product, with its outstanding performance, has ranked first in national production and sales volume for six consecutive years and won the title of “Single Champion in Shandong Manufacturing Industry” in 2024.

• The 6 – 5 Composite Reinforced Beam: Based on the different front – and – rear stress of high – low – board trailers, it adopts a 6 – front – and – 5 – rear composite reinforcement design. The wing plates are 6 – front – and – 5 – rear with additional stiffeners. The front part is strong, and the rear part is rigid, preventing sagging. The compound surface of the gooseneck is repeatedly quenched to form a stress – relief point, effectively enhancing the anti – torsion ability and ensuring no deformation.
• The Arch – surface Ring – hole Stress – relief Beam: It cleverly strengthens the stressed positions and reasonably reduces weight in non – stressed positions. The arch – surface design of the girder makes it horizontal after loading and rebound after unloading. A point is selected at the exact center of the girder web, and a positive – round – hole design is adopted to ensure uniform stress – relief and prevent deformation and fracture.
• The Precision – steel Anti – wear Patented Suspension: The self – lubricating anti – wear balance beam is formed by one – time stamping. An oil – storage wear – resistant plate is installed inside to keep the spring plate in a self – lubricating state for a long time. The precision – steel torsion seat changes the cast – steel process and adopts precision – steel welding. The maintenance – free balance beam pin is repeatedly precision – ground after high – frequency quenching, enabling it to better adapt to complex road conditions.
• The Vertical – horizontal Consolidated Protective Beam: It realizes the integration of the girder, cross – beam, and side – beam, making the structure more stable. The carriage floor has better adhesion, without collapse, no remaining goods, and no leakage, effectively enhancing the service life of the carriage floor.
• The Lightweight High – elastic Plate: It is made of specially customized steel (1035MP), and the material surface is treated with a lightweight process. It is an upgraded material of high – strength plates and alloy steels. It does not expand the box when loading and returns to its original state after unloading. It is vividly called the “carriage plate that an electric drill can’t penetrate” by garage mechanics. These patented technologies not only improve product performance but also win significant advantages for Tongguang Jiuzhou in market competition.
