This emergency suspension bridge offers unmatched portability and speed, with features tailored for rapid deployment. The CFRP main trusses weigh 40% less than steel trusses of the same strength, making them easy to handle by a small team without heavy lifting equipment. Unlike traditional temporary bridges that require weeks to install, this model can be fully assembled and ready for use in 8-12 hours, a critical advantage during disaster response where every minute counts. The modular design allows for flexible span lengths, ranging from 20 to 60 meters, adapting to different crossing needs, such as small rivers, ravines, or damaged roadways. The high-strength aluminum alloy deck with an anti-slip coating provides a stable surface for emergency vehicles and heavy equipment up to 20 tonnes, while the quick-connect locking system ensures structural stability without the need for welding or specialized tools. Additionally, the CFRP material is highly corrosion-resistant, making it suitable for use in flood-prone areas with saltwater or muddy conditions, and it can be reused at least 50 times, offering excellent value for long-term use in multiple emergency or construction scenarios.
Technical specifications include a maximum span length of 60 meters, with a minimum span of 20 meters, allowing for customizable configurations based on the crossing distance. The 4-meter-wide deck accommodates two lanes of emergency vehicles, with a clear height of 3.8 meters to fit ambulances, fire trucks, and light construction equipment. The CFRP main trusses have a tensile strength of 1800 MPa, ensuring structural stability under maximum load. The suspension cables are made of high-tensile steel wire ropes with a breaking strength of 800 kN, providing redundant support. The entire bridge can be disassembled into modular components weighing no more than 200 kg each, making them easy to carry by hand or with small forklifts. Each module fits into standard 20-foot shipping containers, with 4 crates per container, enabling efficient transportation via truck, ship, or aircraft to remote locations. The anti-slip deck has a friction coefficient of 0.85, meeting international safety standards for vehicle traffic. The bridge is designed to operate in temperatures ranging from -30°C to 50°C, suitable for use in most global climates. The quick-connect locking system uses stainless steel pins that can be secured in 2 minutes per connection, ensuring fast and reliable assembly.
This portable modular bridge is a versatile solution for a wide range of time-sensitive scenarios. In disaster response, it is used to replace bridges damaged by floods, earthquakes, or landslides, enabling emergency teams to deliver food, medical supplies, and rescue equipment to isolated communities quickly. For military operations, it provides temporary crossings for troops and armored vehicles in combat zones or training exercises, allowing rapid movement across terrain barriers. In construction sites, it serves as a temporary access route for heavy equipment and materials across small rivers or construction trenches, eliminating the need for building permanent temporary bridges that are costly and time-consuming to remove. It is also suitable for outdoor events, such as music festivals or sports competitions, providing temporary pedestrian crossings over streams or parking lots. Emergency management agencies, military engineering units, construction companies, and event organizers are the primary target customers, with applications focused on rapid, temporary transportation solutions in challenging or time-sensitive environments.
