Adjustable Pole Gin Mounting for Composite Utility Poles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gin tools are not designed to accommodate composite utility poles with fire-resistant coatings and often damage these poles during installation, as they lack the necessary clearance and protection mechanisms.
Innovation Solution
A pole gin tool with adjustable strap attachments and a pin system that allows for secure mounting on various pole types, including composite poles, with rubber padding to prevent damage and provide additional friction for stability, and the ability to hoist loads at angles from 0 to 45 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gin tools are used on composite poles, then the tool can be mounted on the pole, but the fire-resistant coating on the pole is damaged
Solution Approach 1:
A rubber or similar material layer is interposed between the metal plates and the utility pole to prevent direct contact and damage to the fire-resistant coating. This intermediary layer acts as a protective mediator that allows the gin tool to be secured to the pole without harming the pole surface.
Solution Approach 2:
The rubber layer is pre-installed on the plates that contact the pole, providing cushioning protection before any potential damage can occur. This beforehand cushioning ensures that when the gin tool is mounted on the composite pole, the soft rubber material prevents damage to the fire-resistant coating.
2Reliability
If the gin tool is designed for wood or steel poles, then it provides secure mounting, but it lacks clearance to fit over cross arm sections of composite poles
Solution Approach 1:
The gin tool incorporates adjustable portions that can be moved relative to each other, allowing the distance between strap attachments to be varied. This dynamic adjustability enables the tool to adapt to different pole types and configurations, providing the necessary clearance for composite poles with cross arm sections while maintaining secure mounting.
Solution Approach 2:
The gin tool is divided into multiple portions (first portion, second portion, third portion) that can be independently adjusted. This segmentation allows each portion to be positioned optimally for different pole configurations, providing the clearance needed for composite poles while maintaining overall structural integrity and secure mounting.
3Adaptability or versatility
If the strap attachments are fixed in position, then the structure is simple, but the tool cannot accommodate different pole types and configurations
Solution Approach 1:
The adjustable portions with movable connections and multiple pin positions transform the fixed structure into a dynamic system. This allows the strap attachments to be repositioned according to different pole types and configurations, providing versatility while maintaining a relatively simple adjustment mechanism through the pin system.

AI summary
A pole gin including a first portion having a first strap attachment configured to secure the pole gin to a utility pole at a first location and a second portion having a second strap attachment configured to secure the pole gin to the utility pole at a second location spaced from the first location. The first portion and the second portion can be adjustable relative to one another to vary a distance between the first location and the second location.
