Self-Propelled Modular Trailer Detailed Description

ZW Group’s Self-Propelled Modular Trailer is designed to meet the rigorous demands of heavy haulage and oversized cargo transportation. Constructed from high-strength Q550 steel, the main beams feature a sophisticated configuration with 50mm upper plates, 60mm lower plates, and dual 16mm middle plates, providing exceptional structural integrity and resistance to bending under extreme loads. The trailer’s hydraulic suspension system delivers superior shock absorption and stability, allowing for smooth maneuvering across uneven terrain and reducing wear on both the cargo and trailer components.

Equipped with premium Fuwa axles rated at 11.5 tons each and JOST hydraulic landing gear at both front and rear, the trailer ensures reliable load distribution and operational safety during loading, transit, and unloading phases. The detachable hydraulic gooseneck, powered by a 2100cc engine coupled with a 10MCY14-1B pump, offers enhanced flexibility in connecting to various tractors and facilitates efficient loading of heavy equipment.

With an overall length of 21,000mm and width of 2,990mm, the trailer supports a maximum load capacity between 230,000 to 250,000 kilograms. It features 80 high-traction 750R15 tires mounted on durable 6.0-15 rims, ensuring optimal grip and stability. The modular design allows customers to customize axle configurations and deck layouts to accommodate specific cargo sizes and weights, making it an ideal choice for transporting wind turbine blades, bridge sections, heavy industrial machinery, pipes, and cranes.

Strict quality control protocols govern every stage of manufacturing—from steel plate cutting and chassis assembly to precision welding and comprehensive inspections—ensuring each trailer meets international standards for safety, durability, and performance. ZW Group’s Self-Propelled Modular Trailer represents a cutting-edge solution for heavy-duty transport challenges worldwide, combining robust engineering with operational efficiency and adaptability.
