In the domestic bridge operation and maintenance system, as the core channel connecting the aerial working surface, the maintenance inclined ladder has become an important guarantee for the daily maintenance and emergency maintenance of all kinds of bridges with the characteristics of safety, reliability, flexible adaptation and durability and weather resistance.

Passage Innovation for Complex Structure BridgesAiming at the maintenance problem of the steep-slope abutment and the bottom of box girder of continuous rigid bridge, the customized inclined ladder adopts modular segmental design, and can be quickly docked with the pre-embedded parts of the bridge through the adjustable supporting feet, so that the erection can be completed without destroying the original structure. The fully enclosed non-slip steps with double-layer guardrail build a safe working channel, allowing the maintenance personnel to easily reach the hidden positions such as bearing connection section and bellows threading holes, bidding farewell to the high-risk climbing and visual field blindness of the traditional ladder.

All-weather guarding in harsh environments In the operation and maintenance of cross-sea bridges in coastal areas with high salt spray and strong typhoons, the maintenance inclined ladder is made of high-strength anticorrosive materials and fully enclosed structure, which can comfortably cope with salt spray erosion and extreme weather. The combination of anti-seismic damping device and non-slip lighting system ensures safe passage under severe conditions such as heavy rain and dense fog, and becomes a stable channel for “all-weather medical checkup” of the bridge, providing reliable guarantee for long-term operation and maintenance.

Efficient Channel Support for Emergency MaintenanceWhen mountain bridges are suddenly cracked at the bottom of the beams and other emergency hazards, the lightweight inclined ladder unit, with its quick-loading design and convenient transportation, can quickly arrive at the scene of the complex terrain and quickly set up a high-altitude maintenance channel. Without the need for large lifting equipment, the inspection equipment and maintenance materials can efficiently arrive at the work surface, gaining valuable time for emergency disposal and significantly improving the response speed and disposal efficiency of emergencies.

With the customized solution of “one bridge, one policy”, the maintenance ramp is deeply adapted to the structural characteristics and environmental requirements of different bridges. Its safe and stable passage guarantee, flexible and fast installation method, and durable and weather-resistant quality process not only enhance the daily maintenance efficiency, but also become the key link for emergency maintenance of bridges, and build up a reliable “air passage” for the safe operation of China's transportation infrastructure.
