HZ35 Unmanned Landing Trestle Bridge

2. Detailed Product Introduction

2.1 Core Value: Solving Key Pain Points in Landing Operations

• Eliminating Tidal Barriers: As a temporary ship-to-shore channel, it bridges gaps caused by coastal tidal ranges—ensuring continuous access for heavy equipment even as water levels rise or fall, avoiding delays in landing schedules.

• Unmanned Operation Safety: The fully unmanned design removes the need for personnel to work in high-risk beach or near-shore areas (e.g., under enemy fire, rough seas, unstable tidal conditions), significantly reducing operational risks.

• Heavy Equipment Compatibility: A 68t tracked load and 14t axle load enable it to support heavy landing equipment (e.g., armored vehicles, engineering machinery, cargo trucks)—critical for delivering combat or rescue assets to shore.

• Rapid Landing Response: A 15-minute erection time ensures the trestle is quickly operational once ships reach the landing zone, minimizing the exposure window for both ships and equipment during transfer.

2.2 Key Features

• Unmanned & Tracked Mobility: Equipped with a tracked chassis and autonomous power system, it can maneuver independently on soft beach terrain (e.g., sand, mud) without external traction. The unmanned design allows remote control, keeping operators safely on board ships or shore.

• Ship-Accompanying Capability: Built to accompany landing ships during transit, it can be deployed directly from ships to shore upon reaching the landing zone—eliminating the need for separate transportation or pre-positioning.

• Flexible Span Configuration: Offers dual span options: a 35.5m single span for shorter ship-to-shore distances, and 30m per unit for combined spans (to cover longer gaps), adapting to diverse coastal or landing site conditions.

• Heavy-Load Structural Design: Engineered with a 68t tracked load capacity, it withstands the weight of heavy military or emergency equipment; a 14t axle load ensures compatibility with standard wheeled and tracked vehicles.

• Fast Deployment: With a 15-minute erection time, it rapidly establishes a ship-to-shore channel—far faster than traditional manual landing trestles—ensuring equipment transfer begins immediately after ships arrive, reducing operational downtime.

• Beach Terrain Adaptability: The tracked chassis provides strong traction on soft, uneven beach surfaces, preventing sinking or immobilization in sand or shallow water—critical for reliable deployment in non-engineered landing zones.

2.4 Application Scenarios

• Amphibious Landing Operations: Supports military amphibious assaults by providing an unmanned, heavy-load ship-to-shore channel—enabling armored vehicles, artillery, and supply trucks to quickly cross from landing ships to shore, even with tidal fluctuations.

• Coastal Disaster Rescue: In post-tsunami, hurricane, or flood scenarios where coastal infrastructure is destroyed, it establishes a temporary channel between rescue ships and shore, allowing heavy rescue equipment (e.g., cranes, bulldozers) to reach disaster-stricken coastal areas.

• Offshore Construction & Logistics: Facilitates equipment and material transfer between supply ships and offshore construction sites (e.g., wind farm foundations, coastal pipelines) in remote coastal regions with no fixed ports.

• Island Supply Missions: For island outposts or remote coastal communities with limited port facilities, it serves as a flexible landing trestle to transfer food, fuel, and medical supplies from ships to shore, regardless of tidal changes.

• Military Landing Training: Used in amphibious training exercises to simulate real landing conditions, helping forces practice unmanned trestle deployment and heavy equipment transfer in a controlled environment.
