HZ75 Modular Fast Bridge

• Continuous Multi-Span Capability: Eliminates the limitation of single-span bridging systems by enabling continuous multi-span erection (total length 75m, 15m per span), allowing it to cross longer obstacles (e.g., extended dry ditches, winding medium rivers) that single-span bridges cannot cover.

• Rapid Mission Response: Cuts single-span erection time to 9–11 minutes and full-set deployment to 60 minutes, ensuring military vehicles do not face prolonged delays during tactical maneuvers or emergency deployments—critical for maintaining operational momentum.

• Military Vehicle Compatibility: With a 60t tracked load and 13t axle load, it supports a wide range of military vehicles (e.g., armored personnel carriers, military trucks, artillery tractors), while its 3.8m roadway width provides stable passage for standard military vehicle dimensions.

• Harsh Environment Adaptability: The 8×8 off-road chassis enables operation on rough terrain (marshlands, uneven riverbanks), and its 2m/s allowable current velocity ensures reliable deployment even in flowing water—expanding its usability across diverse battlefield and emergency conditions.

2.2 Key Features

• Modular Multi-Span Design: Built with 15m single-span modules that can be connected for continuous erection, achieving a total bridge length of 75m. This modularity allows flexible adjustment of span numbers based on obstacle width, avoiding over-configuration and optimizing resource utilization.

• Ultra-Fast Erection Efficiency: A single span can be erected in just 9–11 minutes (by 7 operators), and the entire 75m bridge set is fully deployable in 60 minutes (by 12 operators). This speed far outpaces traditional non-modular bridges, reducing on-site exposure time in combat or disaster zones.

• Robust Off-Road Chassis: The integrated 8×8 off-road chassis delivers exceptional traction and stability on challenging terrain (marshlands, rocky ground, muddy riverbanks), ensuring the system can reach remote or damaged obstacle sites where standard vehicles struggle.

• Reliable Load-Bearing & Passage: Boasts a 60t tracked load and 13t axle load, meeting the weight requirements of most military vehicles. Its 3.8m roadway width balances maneuverability and stability, allowing safe two-way or single-lane passage for vehicles and accompanying personnel.

• Flexible Trestle Adjustment: Features a trestle adjustment range of 3.32m–5.5m, enabling adaptation to varying terrain heights (e.g., uneven riverbanks, sloped dry ditches). This eliminates the need for additional shimming or terrain modification, streamlining the erection process.

• Water Environment Adaptability: With an allowable current velocity of 2m/s, it can be safely deployed over flowing medium-to-small rivers—avoiding the risk of structural instability caused by fast-moving water and expanding its application in flood-prone or wetland areas.

2.4 Application Scenarios

• Military Tactical Maneuvers: Supports military units in crossing extended medium-to-small rivers, long dry ditches, or marshland stretches during offensive/defensive operations—ensuring armored vehicles, artillery, and supply convoys maintain continuous mobility.

• Battlefield Logistics Support: Enables the rapid construction of multi-span temporary passages for frontline supply lines, ensuring ammunition, fuel, and medical supplies reach troops even when facing long obstacle stretches (e.g., multiple connected dry ditches).

• Flood Disaster Rescue: In flood-hit areas where rivers or waterlogged ditches block rescue routes, it provides a 75m continuous passage for rescue vehicles (e.g., amphibious trucks, emergency ambulances) to reach isolated communities.

• Remote Military Deployment: Assists troops in deploying to remote areas with complex terrain (e.g., mountainous dry ditches, grassland marshlands), where the 8×8 off-road chassis ensures the system can reach the obstacle site, and multi-span design covers long gaps.

• Temporary Military Training Grounds: Used in military training exercises to simulate complex obstacle-crossing scenarios (e.g., multi-span river crossings), helping troops practice modular bridge erection and coordination under realistic tactical conditions.
