Core Viewpoint - China's self-developed SPMT (Self-Propelled Modular Transporter) has achieved a leading position in the heavy transport sector, showcasing advanced engineering capabilities and generating significant rental income for the country [2][11]. Development Journey - The SPMT development program was officially launched in 2007, starting from scratch without any reference designs, data, or experience [4]. - The first SPMT with a Chinese label was produced in 2009, marking a significant milestone in China's heavy transport capabilities [7]. - The second generation of SPMT was introduced in 2014, featuring a modular design and intelligent computer systems, enhancing its operational flexibility [6]. Technological Advancements - The third generation of SPMT was unveiled in 2019, integrating the BeiDou satellite navigation system, enabling features like unmanned driving, obstacle avoidance, and intelligent path planning [9]. - The current SPMT can reach a maximum load capacity of 50,000 tons, with a vehicle length exceeding 100 meters and 1,152 wheels, each capable of supporting 30 tons [9]. Strategic Positioning - China has adopted a "rent, not sell" strategy for its SPMT technology, reflecting a commitment to maintaining control over core technologies [9]. - The SPMT has demonstrated its practical value in various projects, significantly reducing labor costs and time for complex tasks [9]. Future Prospects - The development of the fourth generation of SPMT, which will incorporate AI technology, is already underway, indicating ongoing innovation in this sector [9].
