HZ25 Mountainous Plateau Accompany Bridge

2.1 Core Value: Solving Emergency Railway Loading/Unloading Pain Points

• No Reliance on Fixed Platforms: Eliminates dependence on damaged or non-existent fixed railway platforms, ensuring heavy wheeled equipment (e.g., military vehicles, engineering machinery) can still be loaded/unloaded during emergencies.

• Rapid Emergency Response: With 8-minute erection time for a single erection vehicle and 60-minute full-set deployment, it significantly shortens the response cycle of emergency railway transport, supporting time-sensitive missions (e.g., disaster rescue, military deployment).

• Full Autonomy: Features self-erection, self-retrieval, and self-movement—no external lifting or traction equipment is required, making it suitable for remote or disaster-hit areas where infrastructure is limited.

• Heavy-Load Adaptability: Boasts a 50t tracked load and 17t axle load, capable of handling heavy wheeled equipment (e.g., armored vehicles, large engineering trucks), meeting both military and civil emergency transport needs.

2.2 Key Features

• Integrated System Design: The whole set consists of 2 erection vehicles and 1 transporter vehicle, with modular collaboration that ensures efficient loading/unloading—each erection vehicle provides a 14m roadway, and the full set forms a 54m continuous roadway (4m width) to accommodate long or multiple heavy equipment.

• Ultra-Fast Erection: A single erection vehicle can be erected in just 8 minutes (operated by 2 people), and the entire system is fully deployable in 60 minutes (operated by 6 people), far outpacing traditional temporary platform solutions.

• Strong Mobility of Erection Vehicles: Each erection vehicle has a curb weight of 38t, a maximum speed of 78km/h, and excellent off-road performance (42% max gradability, 27m min turning diameter, 27° approach angle, 23° departure angle), enabling quick movement between emergency sites.

• High Load-Bearing Capacity: With a 50t tracked load and 17t axle load, it can safely support heavy wheeled equipment, ensuring stable loading/unloading even for large military or engineering vehicles.

• Proven Reliability: As a participant in the Military Parade of the 70th Anniversary of the People’s Republic of China, its performance and durability have been rigorously tested in high-stakes scenarios, ensuring trustworthiness in emergency situations.

2.4 Application Scenarios

• Emergency Railway Transport: When fixed railway platforms are damaged by natural disasters (earthquakes, floods) or man-made incidents, it enables rapid loading/unloading of heavy rescue equipment (e.g., engineering cranes, disaster relief vehicles) to support on-site rescue.

• Military Equipment Deployment: Facilitates quick transfer of heavy military wheeled equipment (e.g., armored vehicles, missile launchers) via railways in wartime or emergency missions, ensuring rapid troop and equipment maneuvering.

• Railway Infrastructure Maintenance: Serves as a temporary platform during railway construction or fixed platform maintenance, allowing heavy maintenance machinery to be loaded/unloaded without disrupting normal railway operations.

• Remote Area Logistics Support: In remote regions with underdeveloped fixed railway infrastructure, it provides a mobile loading/unloading solution for heavy supplies (e.g., mining equipment, large agricultural machinery), supporting local economic construction.

• National Defense & Parade Missions: As proven by its participation in the 70th National Day Military Parade, it is a key equipment for high-standard national defense demonstrations and emergency preparedness.
