Auger Stand for Digger Derrick Pole Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digger derricks are often used beyond their design capabilities, leading to damage and potential catastrophic failure when used to pull poles out of the ground, and there is a lack of protection for the auger when stowed, making it vulnerable to elements and damage.
Innovation Solution
An auger stand that serves as both a protective cover and a lifting mechanism for the auger, featuring a hollow inner cavity, a load-bearing landing, and an anchoring mechanism to prevent rotation, allowing for safe and efficient lifting of poles without damaging the boom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the digger derrick is used to pull poles out of the ground using the boom and winch, then the pole can be extracted from the ground, but the dynamic loads can lead to damage and catastrophic failure of the boom
Solution Approach 1:
The invention extracts the pole pulling function from the digger derrick's boom system by introducing a separate auger stand that independently performs the extraction function. The auger stand with its anchoring mechanism and rotating auger handles the pole removal, while the boom remains dedicated to lifting operations only, thus preventing damage to the boom structure.
Solution Approach 2:
The system is segmented into distinct functional components: the digger derrick handles digging and lifting, while the separate auger stand handles pole extraction. This segmentation allows each component to operate within its designed capacity without imposing harmful dynamic loads on other parts of the system.
2Strength
If separate stand-alone pole pulling systems are employed, then the pole can be pulled out safely, but the systems are expensive and crowd workspace when used near the digger derrick
Solution Approach 1:
The invention merges the auger stand with the digger derrick system by positioning it on the ground near the boom base and integrating it into the overall pole maintenance workflow. This combination provides safe pole extraction functionality while minimizing workspace occupation and system cost compared to completely separate stand-alone systems.
3Ease of operation
If the auger is stowed on the boom without a cover, then the auger is accessible and easy to install, but it is vulnerable to the elements, potentially leading to physical damage and rust
Solution Approach 1:
The auger stand serves multiple functions: it provides a base for the auger during operation, acts as a protective cover when the auger is stowed, and offers structural support. This multi-functionality protects the auger from elements while maintaining ease of installation and operation.

AI summary
An auger stand, system, and method of use thereof for lifting a longitudinal object. The auger stand comprises at least one wall section forming a hollow inner cavity for receiving an auger, a landing to support a load from the auger and provide an upward thrust, and a base for supporting the auger stand including an anchoring mechanism to prevent rotation of the auger stand. During operation, the auger is rotated in a first direction to screw into the auger stand and rotated in a second direction to unscrew from the auger stand and lift the longitudinal object. The auger stand may also be used as a cover to protect the auger and a stand to support the auger in an upright position.
