Tilting Bridge Platform with Integrated Fall Arrest Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transshipment docks face challenges such as static platforms, varying vehicle heights, and harsh weather conditions, leading to safety risks for operators and increased complexity in installation, particularly due to the need for extensive civil engineering works.
Innovation Solution
A back-to-back tilting bridge with an electro-hydraulic or pneumatic system, featuring a sheet metal platform, side skirts, integrated buffers, and a one-piece frame, which forms a fall arrest barrier and allows for safe pedestrian passage, and can be installed quickly without major civil works by fitting within standard dock shelters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional static transshipment docks are used, then the structure is simple and stable, but the difference in level between the quay and various vehicles cannot be accommodated, creating safety risks and preventing passage
Solution Approach 1:
The bridge is designed as a movable structure that can tilt and adjust its angle relative to the quay. The platform can rotate around a horizontal axis to adapt to different vehicle bed heights, transforming the static dock into a dynamic system that maintains adaptability while managing structural complexity through controlled motion mechanisms
Solution Approach 2:
The bridge structure serves multiple functions: it acts as a walkway for operators, provides a barrier to prevent falls, enables passage for trolleys and cargo, and adapts to various vehicle types. This multi-functionality addresses the adaptability requirement while the integrated design helps manage overall structural complexity
2Reliability
If dock levelers with barriers and refuge zones are used, then operator safety is improved, but many voluminous parts are required which need major civil engineering work at the quay
Solution Approach 1:
The bridge integrates multiple safety and functional elements into a single unified structure. The barrier, platform, and support mechanisms are combined into one assembly that can be installed as a complete unit, reducing the need for separate civil engineering works while maintaining comprehensive operator safety protections
Solution Approach 2:
The bridge is designed as a modular structure with distinct segments that can be assembled and installed separately. The platform, barriers, and support components are segmented to facilitate easier transportation and installation, reducing the major civil engineering work required at the quay location
3Stability of the object's composition
If autodock bridges with multiple feet and support studs are installed, then structural stability is improved, but complicated civil works are required including installation of support studs for each foot
Solution Approach 1:
The bridge uses an integrated frame structure where the support function is merged into the main body of the bridge rather than requiring separate support studs. The frame itself provides structural stability while eliminating the need for additional civil engineering installations, simplifying the overall installation process
4Ease of operation
If the bridge is designed to allow operator access to open curtain doors, then operational flexibility is improved, but operators face risks of falls, crushing, and injuries
Solution Approach 1:
The bridge platform extends to provide a safe working surface that reaches the vehicle bed level before operators need to access the curtain doors. This prior positioning of the platform eliminates the need for operators to stand in voids or precarious positions, cushioning them from fall and crushing risks while maintaining operational flexibility

AI summary
The bridge (1) has a single piece frame provided with integrated stops (3) on an outer surface, where the stops are placed laterally. A central space forms refuge with sheet cap on an interior face turned toward a quay. An onboard hydro-electric power station is provided inside the frame. The platform is articulated on the frame, where the platform is raised under pivoting effect of a central jack (24) in quasi vertical position of anti-fall quay and descended in work, floating and/or fixed position. The platform is controlled by the hydro-electric power station. An independent claim is also included for a method for installing a leaning bridge.
