The frame of the 3-axle skeletal trailer is made of welded longitudinal beams and through-type cross beams using high-strength steel, forming a spatial frame structure. It features a reasonable design, strong load-bearing capacity, balanced overall strength and rigidity, good elasticity, long service life, and no permanent deformation.
The 3-axle skeletal trailer is specially designed for efficient and reliable container transportation. Its main components are processed using advanced equipment, and the longitudinal beams are welded with fully automatic tracking submerged arc welding machines, ensuring a strong and impact-resistant structure. The trailer remains stable without loosening during bumps, effectively reducing tire wear and extending service life. With a well-designed structure, it is suitable for container logistics, port operations, and long-distance transportation, meeting various road load-bearing requirements.
● Advanced Manufacturing Process:
Produced with automated submerged arc welding, CNC cutting, and precision assembly lines to ensure consistent quality and strong structural integrity.
● High-Strength Steel Frame:
Built from high-tensile, wear-resistant steel with optimized frame design for superior torsion resistance and long-lasting durability.
● Optimized Structural Design:
The welded longitudinal beams and through-type cross beams form a stable space frame structure, ensuring high load-bearing capacity and excellent elasticity without permanent deformation.
● Reliable Performance on All Roads:
Enhanced chassis stability reduces tire wear and vibration, ensuring smooth operation under heavy-duty and long-distance transport conditions.
● Strict Quality Inspection:
All key welding joints undergo ultrasonic or X-ray inspection to guarantee the safety and reliability of every trailer.
● Large-Scale Production Capacity:
Manufactured in a modern facility with full-process quality control, ensuring stable supply, fast delivery, and consistent product performance.
● Low Maintenance, High Value:
Simple structure, easy operation, and low maintenance cost — maximizing your transport efficiency and long-term investment return.
