Technological innovations enable modernization, and Shandong Lutong is accelerating to take a leading position in the high-end drive axle market

Shandong Lutong Company, which has been actively working in the field of drive axles for many years, has always taken technological innovation as its core driving force, focusing on the continuous upgrading of key transmission components for construction and agricultural machinery, and constantly breaking through the bottlenecks of traditional drive axle manufacturing technology. Relying on solid R&D experience and rich production experience, the company has recently completed large-scale development of two major products, upgraded the T400s wet tractor drive axle, innovated the LTG27 steering drive axle, and comprehensively supplemented the high-quality drive axle product line. The excellent product performance precisely meets the needs of major equipment manufacturers for high-end support, helping the entire machinery industry improve quality and efficiency and advance to a high level.

Regarding the drive axle of agricultural machinery, considering the complexity and high-intensity operation of powerful tractors in the field, the company has completed a comprehensive iterative upgrade of the drive axle for the 400-horsepower tractor, innovating and replacing the classic T400 tractor drive axle with drum brakes with the new T400s tractor drive axle featuring wet drive, achieving a technological breakthrough in the braking system of agricultural high-power drive axles. The drive axle of traditional brake tractors is equipped with a drum brake, which is prone to wear and contamination in harsh operating conditions such as muddy farmland, dust, swampy terrain, gravel, etc., over long periods. At the same time, during prolonged continuous operation under heavy loads, poor heat dissipation can easily lead to brake heat fade, rapid wear of friction linings, reduced braking force, brake pull, and other issues, resulting in high equipment maintenance frequency, high operation and maintenance costs, and stability and durability that are difficult to adapt to the all-weather, long-life operation needs of modern high-quality, high-power tractors. The new T400s tractor drive axle with wet drive adopts an industry-leading fully enclosed wet brake design. The friction brake pair is built into the hub cavity and fully immersed in special lubricating oil. To achieve constant temperature, a combination of oil immersion heat dissipation and forced lubrication and heat removal is used for the operation of the braking system, which eliminates the major industry problems of poor heat dissipation, easy removal, and easy failure of traditional drum brakes.

The fully upgraded T400s wet tractor drive axle offers several key advantages, including stable braking, high load capacity, broad adaptability to working conditions, and a long, maintenance-free service life. The enclosed oil bath working environment protects the braking system from external dust, dirt, and high or low ambient temperatures. Whether deep plowing in rice fields, intensive dry land tillage with harrows, or long-distance transport, it provides consistent and stable braking force. Compared to traditional drum brake drive axles, the service life of this wet drive axle is increased by 3 to 5 times, significantly reducing the time for accessory replacement and maintenance downtime, effectively improving the operational efficiency of agricultural machinery and lowering the total lifecycle cost of the entire machine. As a core transmission component for 400-horsepower tractors, the T400s wet tractor drive axle precisely aligns with the development trends of high-end agricultural machinery, delivering efficiency, stability, and energy savings, and providing reliable support for domestic high-horsepower tractors as they enter the high-quality agricultural machinery market.

At the same time, in the field of auxiliary construction machinery and equipment, Shandong Lutong has carried out in-depth technical refinement based on the advanced LTG32 telescopic forklift drive axle, and has developed and launched the LTG27 steering drive axle to introduce a new form of integrated, lightweight, and high-performance telescopic forklift drive axle, filling technical gaps in industry segmentation. The traditional design of the telescopic forklift drive axle with a separate gearbox is complex, takes up a lot of space, has high transmission losses, and is difficult to assemble, limiting the compactness and operational flexibility of the entire machine.

The biggest technological highlight of the LTG27 steering drive axle is the industry-breaking design of a two-speed gearbox and axle housing, which completely eliminates the cumbersome structure of traditional drive axles with telescopic forks and separate gearboxes, achieving a high degree of integration of the three main transmission modules. The steering system and drive system are combined into a single axle structure. This new version of the telescopic forklift axle fully addresses industry issues such as the large space occupied by traditional separate structures, long transmission chains, high power loss, cumbersome assembly, and high failure rates. The integrated design not only significantly simplifies the overall machine layout, saves installation space, reduces equipment weight and power transmission losses, but also utilizes the two-speed transmission function to flexibly switch operating modes. The low-speed gear can meet the high torque requirements for heavy lifting and stacking operations, while the high-speed gear is adapted to the efficient needs of construction site transport and short-distance travel, perfectly balancing the equipment's traction and operational efficiency. At the same time, the integrated axle structure offers greater rigidity, higher transmission accuracy, and greater operational stability, significantly reducing the likelihood of equipment failure, and is fully adapted to the strict standards of high-quality telescopic forklifts for high efficiency and reliability.

Starting from the radical improvement of the wet braking technology for agricultural tractor drive axles to the innovative breakthrough in the integrated design structure of telescopic fork and steering drive axles, the successful launch and mass production of two new products fully demonstrate Shandong Lutong's innovation potential in the research, development, design, and manufacturing of various drive axles. This also marks the official completion of the company's strategic transition from traditional general-purpose drive axle manufacturing to the research, development, and production of high-end customized drive axles. After years of deep cultivation and iteration, Shandong Lutong has established a comprehensive high-quality product system covering a full range of major categories, such as agricultural tractor drive axles, telescopic fork loading drive axles, and special integrated steering drive axles, fully adapted to the two main auxiliary scenarios of agricultural and engineering machinery. Relying on advanced intelligent production lines, a strict full-process quality control system, a professional R&D team, and rapid customization service capabilities, the company can provide high-quality and cost-effective high-end drive axle support solutions to major construction and agricultural machinery manufacturers both domestically and abroad.

In the future, Shandong Lutong will continue to deepen research and development in drive axle technology, focusing on high-quality, integrated, energy-saving, and maintenance-free product upgrades, while continuing to overcome technical barriers in the industry. Through better products and more professional support services, Shandong Lutong will collaborate with major equipment manufacturers to achieve mutually beneficial development and help domestic construction and agricultural machinery fully transition to a high level.
