Engineered to redefine structural reliability, the 900 Support Truss incorporates advanced architectural mechanics to deliver exceptional performance in the field. Every element is designed to accelerate deployment while maximizing safety margins.
Flawless Modular Integration: The standardized pin-and-bolt connection system allows for seamless interlocking between the bailey panels, eliminating the need for complex on-site welding.
Exceptional Load Distribution: The geometric configuration of the upper and lower chords efficiently disperses heavy dynamic loads, preventing localized stress fractures.
High-Tolerance Manufacturing: Precision-cut components ensure that male and female end posts align perfectly, drastically reducing assembly friction and labor hours.
Enhanced Structural Rigidity: Integrated vertical and horizontal bracing mechanisms prevent lateral swaying, ensuring a stable deck surface even under high-wind conditions or heavy traffic.
Optimized Weight-to-Strength Ratio: Despite its massive load-bearing capacity, the truss design minimizes unnecessary bulk, facilitating easier lifting and positioning with standard lorry-mounted cranes.
By utilizing this advanced truss framework, project developers can confidently execute complex erection sequences, knowing that the foundational geometry will support both the temporary construction loads and the final operational traffic.
The foundation of any enduring infrastructure lies in its metallurgical integrity. We utilize premium high-strength structural steel, such as Q345B, to forge the core framework of the 900 Support Truss. This material selection guarantees exceptional tensile strength and resistance to mechanical fatigue, ensuring the bridge remains steadfast under continuous heavy-duty cycles.
To combat the relentless assault of environmental degradation, each component undergoes a rigorous surface protection protocol.
Hot-Dipped Galvanization: Components are submerged in molten zinc, creating an impenetrable metallurgical bond that seals the steel away from moisture, salt, and oxygen.
Inorganic Zinc-Rich Coating: An alternative heavy-duty painting process that provides active cathodic protection, sacrificing itself to prevent the underlying steel from rusting.
Extreme Environment Resilience: Whether deployed in highly corrosive coastal regions, humid tropical jungles, or freezing alpine passes, the treated surface actively repels oxidation.
Extended Lifespan: This meticulous attention to anti-corrosion detailing drastically reduces the need for frequent maintenance, securing a prolonged operational life and a superior return on investment.
Recognizing that no two geographical challenges are identical, we deliver comprehensive engineering flexibility. Our technical team does not just supply parts; we provide a complete architectural solution tailored to the precise demands of your site.
Complimentary Structural Calculation: Our engineers conduct rigorous load-bearing and stress-distribution analyses at no extra cost, ensuring the proposed configuration is mathematically sound.
Bespoke Drafting Services: We generate detailed CAD drawings customized to your specific span requirements, lane widths, and expected traffic volumes.
International Standard Compliance: Every custom design is meticulously cross-referenced to meet or exceed stringent global design codes, including AASHTO, GB, DIN, and BS standards.
Terrain-Specific Adaptability: Whether the project requires a reinforced lower chord for a longer unsupported span or specialized abutment bearings for uneven riverbanks, the truss system can be modified to conquer the topography.
This proactive approach to engineering design empowers procurement teams and project managers to acquire a bridging system that perfectly aligns with their unique operational parameters, eliminating the risks associated with one-size-fits-all solutions.

We have studied the drawings of the erection site and surrounding area, and conclude that the installation site is spacious and flat,so we recommend the installation procedure as follows:
1. Assemble the bilateral bailey panels to two whole construction, including the lower chord reinforced、horizontal bracing、vertical bracing、male and female end post. every assembling unit is mainly composed by 27 pieces of bailey panel
Meanwhile, the bridge bearings are installed on the abutment. note that：check the length of the single whole bailey truss and the distance between the bolts of the two side of the river, if not fit , adjust the bolts.
2. Use suitable lorry-mounted crane to lift the two assembling truss unit and place them on the two side abutments.the single combined truss unit is weight about 11tons and 27.4 m length.
3. Install the transom, please refer the video.for the weight of one piece of transom is about not more than 1 ton，so it need a small crane. In order to increase the stability of the structure during the erection, the nearest transom and the farthest transom, as far as possible according to the capacity of the crane, should be installed first, then for other transoms between them.
4. Install the sway bracing，then pave the first row in width direction of bridge decking on the transoms, including the side and middle bridge decking.
Meanwhile, install the upper chord reinforced to strengthen the structure,then the crane could move onto the bridge decking to install the following ahead transoms,similar ways like upper procedure to be perform.
5. The rest can be done in the same manner.
6. Final, install the upper chord reinforced、curb、gap plate、handrail、 connective plate and handrail column.
