Vertical Ladder Fall Protection With Tensioned Cable Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall protection systems for vertical ladders are difficult to install and maintain, failing to comply with safety operational requirements.
Innovation Solution
A fall protection system comprising a top bracket assembly, a bottom bracket assembly, and a cable extending between them, which can be easily mounted to a vertical ladder using U-shaped coupling devices and Belleville washers to achieve the desired tension, minimizing vertical loading and ensuring compliance with safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fall protection system is installed on a vertical ladder, then fall protection function is provided, but installation difficulty and maintenance complexity increase
Solution Approach 1:
The fall protection system is divided into separate modular components: a ladder cage assembly and a cable assembly. The ladder cage includes rungs and side rails that can be independently installed on the ladder, while the cable assembly with grab device can be separately attached. This segmentation allows each component to be installed and maintained independently, reducing overall installation difficulty and maintenance complexity while maintaining fall protection functionality.
2Reliability
If a cable is positioned adjacent to the ladder for fall protection, then safety function is achieved, but system complexity and inspection difficulty increase
Solution Approach 1:
The cable assembly is integrated with the ladder cage assembly to form a unified fall protection system. The cable is positioned within or adjacent to the ladder cage structure, combining the protective enclosure function with the fall arrest function. This merging reduces the number of separate components and simplifies the overall system structure, making it easier to inspect and maintain while preserving both safety functions.

AI summary
A fall protection system having a top bracket assembly that is mountable to a top portion of the ladder, a spaced bottom bracket assembly that is mountable to a bottom portion of the ladder, and a cable extending therebetween portions of the top bracket assembly and the bottom bracket assembly substantially parallel to a plane bisecting the vertical ladder at a desired distance from the plane.
