Standard Beam Transport Semi-Trailer

JinFeng China Standard Beam Transport Semi-Trailer is a heavy-duty special load-bearing equipment developed for precast girder transportation in bridge engineering, tailored to meet the safe transit needs of large-tonnage bridge components such as box girders and T-beams. The vehicle body is welded with high-strength steel plates and equipped with a multi-axle hydraulic suspension system, enabling even load distribution and significantly improving driving stability under heavy-load conditions. The dedicated load-bearing platform is precisely designed to perfectly fit the support points of precast girders, preventing component damage caused by uneven stress during transportation. Its modular structure adapts to bridge components of different lengths and tonnages, allowing flexible adjustment of wheelbase and load platform dimensions to meet transportation needs of various bridge construction scenarios.

Product Advantages

1.  Outstanding Load-Bearing Performance : Built with a large-tonnage dedicated load-bearing structure, the hydraulic suspension system enables automatic load balancing, greatly reducing road impact during heavy-load transportation and effectively protecting bridge components.

2.  Flexible and Reliable Operation : Equipped with an independent steering system supporting multiple steering modes, it can maneuver flexibly in narrow construction sites and adapt to complex road conditions such as tunnel entrances and roadbed sections.

3.  Excellent Durability : Key components use well-known brand hydraulic parts and axles. The vehicle undergoes rigorous working condition tests with excellent anti-fatigue and anti-overturning performance, ensuring a long service life.

4.  Wide Compatibility : The modular design allows quick adjustments according to different precast girder specifications, meeting customized transportation needs of various bridge projects with strong versatility.

Usage and Maintenance

·  Usage Specifications : Before transportation, confirm that the precast girder's support points are fully aligned with the load-bearing platform and secure the components as required. Control vehicle speed during operation, avoiding sudden braking and turns, and slow down when passing ramps and curves.

·  Daily Maintenance : Regularly check the Standard Beam Transport Semi-Trailer hydraulic system's sealing and suspension component tightness, and fill with qualified hydraulic oil and lubricating oil. Clean debris from the vehicle body after each operation and inspect tire wear and pressure.

·  Periodic Maintenance : Conduct comprehensive inspections of axles, hydraulic pumps, and steering systems according to the cycle, replacing aged seals and wearing parts to ensure stable equipment operation and reduce failure risks.
