The Compact Panel Bridge series adopts a modular design, with core advantages of large span coverage, short construction period, and fast erection. Its bridge components feature high reusability, excellent interchangeability, and reliable connection performance, supporting flexible structural design based on actual span and load requirements to build temporary or semi-permanent bridges. The series now includes five models: CB100, CB200, CB200A, CB250, and the newly added CB300.

2.1 Core Product Value: Solving the Pain Points of "Fast Bridge Construction, Flexible Adaptation, Cost Controllability, and Dual Military-Civil Application"

  • Military Scenarios: For military operations or training, the CB300 model can quickly build temporary bridges to ensure artillery and vehicles pass through obstacles, supporting timely troop maneuvering and equipment deployment.

  • Emergency Scenarios: After natural disasters (floods, earthquakes) causing road interruptions, all models (including CB300) can rapidly erect temporary access to guarantee the transportation of rescue materials and personnel evacuation; the CB300’s fast disassembling feature also facilitates post-disaster site clearance.

  • Engineering Scenarios: During infrastructure construction (highways, railways, water conservancy), the series (especially CB300 with 6-72m span) meets temporary cross-river/ditch traffic needs, shortening construction cycles and avoiding project delays.

  • Long-Term Adaptation: All models support semi-permanent use; for remote areas, temporary settlements, or military temporary positions, they can replace traditional long-cycle bridges, reducing construction and maintenance costs.

2.2 Core Features: Multi-Dimensional Advantages Driven by Modular Design

  • Modular & Standardized Structure: All components (including CB300’s panels) are standardized for production, with the CB300’s panel dimension of 2.28m × 3m (Length × Width × Height) enabling easy stacking and transportation. On-site construction requires no complex processing, and the CB300’s fast launching/disassembling feature further shortens the erection cycle (comparable to other models in the series, reducing over 50% of construction time vs. traditional bridges).

  • High Reusability & Wide Compatibility: Bridge components of the series (including CB300) can be disassembled and reused multiple times; the CB300 shares consistent carriageway widths (4.2m single lane / 7.35m double lane) with other models, ensuring partial accessory universality and lowering later maintenance costs.

  • Flexible Adaptability to Scenarios: The series covers spans from 6m to 87.6m (CB300: 6m-72m) and load capacities up to 60t (CB300: HL93, HA, HB, Tacked Load 60t), supporting both single-lane and dual-lane designs. The CB300’s dual military-civil application capability further expands its scenario coverage.

  • Stability & Durability: Mainstream models (including CB200/CB200A/CB250/CB300) adopt steel decks, ensuring strong load-bearing performance and compatibility with international load standards such as HL93 and HS25-44, suitable for long-term semi-permanent use.

2.4 Application Scenarios

  • Military Operations: The CB300 model supports military temporary bridge construction, ensuring artillery and vehicles pass through obstacles, and adapting to rapid troop maneuvering needs.

  • Emergency Rescue: All models (including CB300) quickly restore traffic access after disasters such as earthquakes, floods, and mudslides, guaranteeing rescue material transportation.

  • Engineering Construction: Suitable for highway/railway construction and water conservancy projects; the CB300’s 6-72m span meets most temporary cross-obstacle traffic needs.

  • Remote Areas & Temporary Settlements: All models support semi-permanent use, replacing traditional long-cycle bridges to reduce construction costs in rural areas, mining areas, and scenic spots.

  • Temporary Events: Provides temporary cross-road access for large-scale competitions, exhibitions, and other events, with fast erection and disassembling to avoid affecting normal traffic.
