HD200 Steel Bailey Bridge Double Rows Single Layer Reinforced DSR Double Lanes Specifications

Main Components

You work with a bailey steel bridge system that features advanced engineering and robust materials. The HD200 model uses a double rows single-layer reinforced DSR design. This configuration increases the overall stiffness and stability, which allows the bridge to handle heavy loads safely. The main components include panels, chords, and decking systems. Each part is manufactured from high-strength steel, which ensures durability and long service life. The modular nature of the bailey steel bridge simplifies construction and adapts to different terrains. You benefit from a span capability of up to 91 meters, making this bridge suitable for a wide range of infrastructure projects. Evercross bridge’s production line in Shanghai delivers consistent quality and meets strict ISO standards.

Fasteners and Accessories

You assemble the HD200 bailey steel bridge using specialized fasteners and accessories. These include Bailey U-steel deck bolts, panel bolts, and truss bolts. Each bolt connects panels, trusses, decks, and chords, forming a secure structure. For example, you insert the U-steel deck bolt into the truss chord member from top to bottom, ensuring the bending pad fits inside the chord member before tightening the nut. This process guarantees a strong connection and enhances the bridge’s load-bearing performance. The use of high-strength steel in these fasteners supports the overall safety and reliability of the bridge.

• Bailey U-steel deck bolt
• Panel bolt
• Truss bolt

Tip: Always check the specifications of each fastener to match the load requirements of your project.

Support Materials

You rely on support materials that complement the main components and fasteners. These materials include bearing plates, reinforced pads, and alignment tools. Each support item plays a role in distributing loads and maintaining the correct geometry of the bailey steel bridge during and after installation. Evercross bridge provides all necessary support materials as part of the complete kit, ensuring you meet quality assurance standards. You can trust that every component and accessory has passed rigorous testing before leaving the production line.

Assembly Process and Installation Regulations

Positioning and Marking

You start the assembly of the HD200 steel bailey bridge double rows single layer reinforced DSR double lanes by marking the exact location for the bridge. Use survey equipment to set out the centerline and endpoints. Mark the abutment and pier positions clearly. This step ensures the bridge aligns with the road and meets the load design requirements. Accurate marking helps you avoid costly adjustments later in the installation. Always double-check your measurements before moving forward.

Tip: Use brightly colored stakes and flags to make your markings visible to all team members during the erection process.

Pier Construction

You construct the piers to support the hd200 bailey bridge. Begin by excavating the foundation to the required depth. Place reinforced concrete or steel supports according to the engineering drawings. The piers must match the large bearing capacity of the bridge. Install bearing plates on top of each pier to distribute the load evenly. Check the alignment and elevation of each pier before the concrete sets. Proper pier construction ensures the bridge can handle heavy loads and maintain stability.

Panel Assembly

You assemble the bailey panels on a flat surface near the installation site. Lay out the panels for the double-row single-layer reinforced type. Connect the panels using high-strength pins and bolts. Insert hollow sleeves at the joints to meet installation regulations. This step increases the strength and rigidity of the hd200 steel bailey bridge double rows single layer reinforced dsr double lanes. Use cranes or hoists to lift the assembled panels into position. The modular design allows for fast erection and easy disassembly if needed.

• Lay out panels in sequence
• Connect panels with pins and bolts
• Insert hollow sleeves at joints
• Lift panels into place

Reinforced DSR Installation

You install the reinforced DSR components to enhance the bridge’s load and capacity. Attach the diagonal and vertical bracing to the bailey panels. Secure each connection with the specified fasteners. The reinforced DSR system increases the stiffness of the hd200 steel bailey bridge double rows single layer reinforced dsr double lanes. This step ensures the bridge meets the required bearing and load standards. Follow the manufacturer’s guidelines for spacing and tightening.

Note: Always inspect each connection for proper fit and alignment before moving to the next stage.

Decking and Alignment

You place the steel decking panels across the assembled bailey structure. Align each deck panel to create a smooth driving surface. Secure the decking with bolts and locking plates. Check the alignment of the entire hd200 bailey bridge to ensure it matches the road profile. Proper alignment prevents uneven load distribution and extends the bridge’s service life. The modular decking system supports easy disassembly and maintenance.

Structural Tightening

You complete the installation by tightening all bolts and connections. Use a torque wrench to apply the correct force to each fastener. Inspect the entire hd200 steel bailey bridge double rows single layer reinforced dsr double lanes for any loose or misaligned parts. Tighten the truss connections and check the hollow sleeves for secure placement. This step guarantees the bridge achieves its full load and large bearing capacity. Follow the installation regulations for final checks.

Safety Reminder: Always wear safety gear and follow site protocols during tightening and inspection.

You have now completed the main assembly of the hd200 steel bailey bridge double rows single layer reinforced dsr double lanes. The modular bailey design, fast erection process, and easy disassembly features make this bridge ideal for projects that require reliable performance and efficient installation.

Safety Inspection and Final Checks

Structural Assessment

You must carry out a thorough structural assessment before opening the bridge to traffic. Start by inspecting every panel for damage, defects, or deformation. Check all dowels, bolts, beam fixtures, and sway braces to confirm proper assembly. Measure the mid-span deflection and compare it with the expected values. Look for cracks or unevenness in the panels. Monitor the foundation for any signs of uneven settlement. Apply grease to pins and exposed threads to prevent rust. Address any paint peeling, rust, or deformation immediately.

• Inspect bridge panels for damage or deformation
• Confirm assembly of all bolts and fixtures
• Measure mid-span deflection
• Check for cracks or uneven settlement
• Lubricate pins and exposed threads
• Repair paint or rust issues

Tip: Regular inspections help you maintain the bridge’s integrity and extend its service life.

Load Testing

You need to verify the bridge’s performance through a series of load tests. Begin by measuring and recording the test point at the center of the largest span. Pass a small unloaded vehicle over the bridge several times to check for excessive deflection. Next, conduct an 80% standard load test and record the deflection values. Perform a standard load test using the design-approved load, then follow with an overload test at 120% of the design standard. Record all data carefully. Use test vehicle speeds of 5 km/h, 10 km/h, and 15 km/h to simulate real-world conditions.

1. Measure and record the center span test point
2. Pass an unloaded vehicle multiple times
3. Conduct an 80% standard load test
4. Perform a standard load test at design-approved weight
5. Complete an overload test at 120% of the design load

Evercross bridge’s rigorous testing and ISO certification ensure your bridge meets international safety standards.

Site Cleanup

After completing all inspections and tests, you should clean the site thoroughly. Remove leftover materials, tools, and debris from the area. Check that all safety barriers and signage remain in place. Restore the surrounding environment as needed. A clean site not only improves safety but also presents a professional image for your project handover.

• Collect and remove all tools and waste
• Inspect for any remaining hazards
• Restore the site to its original condition
