Self-Propelled Modular Trailer Detailed Description
Structural Integrity and Advanced Materials
ZW Group’s SPMT is engineered to meet the rigorous demands of extreme heavy haulage. The main structure is built from high-strength Q550 steel. Specifically, the main beams feature a sophisticated configuration (e.g., 50mm upper plates, 60mm lower plates, and dual 16mm middle plates). This design provides exceptional structural integrity and resistance to bending under maximum loads.
Moreover, the trailer is not merely a towed unit; it features an integrated hydraulic suspension system. This critical system delivers superior shock absorption and stability, allowing for smooth maneuvering across uneven terrain. Furthermore, the modular design allows full customization of axle configurations, offering capacity scalability from 200 tons up to 2,500 tons depending on the specific assembly.
Hydraulic Power and Precision Control
The unit is equipped with premium axles (FUWA/BPW) rated at 11.5 tons each and JOST hydraulic landing gear, ensuring reliable load distribution. Crucially, the detachable hydraulic gooseneck offers enhanced flexibility in connecting to various tractors. The entire system is powered by an integrated 2100cc engine coupled with a high-performance 10MCY14-1B pump. Additionally, all axles feature hydraulic steering, providing superior maneuverability and precise control in confined spaces—a necessity for transporting delicate, ultra-heavy modules.
