TSR Temporary Emergency Mabey Panel Bridge - 12m Span Galvanized Truss with 100 Ton Capacity
TSR Temporary Emergency Mabey Panel Bridges are galvanized truss bridges designed for rapid deployment in critical situations. These modular bridges provide reliable temporary crossings for emergency response and infrastructure projects.
During flood emergencies, Type 321 Bailey Bridges enable quick construction of temporary passages for rescue personnel and supplies. In a Yulin City drill, 21 emergency team members erected a 12-meter span, 3.75-meter wide bridge in just 1.5 hours.
Following the 2008 Wenchuan earthquake, multiple Type 321 Bailey Bridges facilitated critical transportation for relief materials, medical evacuations, and civilian movement.
Originally designed for military applications, these bridges support rapid deployment in combat readiness operations and military engineering projects.
For temporary crossings over rivers, gullies, and damaged bridges, Type 321 Bailey Bridges maintain traffic continuity with load capacities up to 100 tons.
In water conservancy projects, these bridges serve as construction channels and temporary access routes for equipment and materials.
