Pole Lifting Device Using Segmented Mast and Hoist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for installing and removing light poles on concrete pedestals are complex, expensive, and require heavy equipment, making them difficult to handle and costly for widespread use in applications like parking lots.
Innovation Solution
A modular, portable pole lifting and setting device with a base section, mast sections, and a hoist mechanism that allows for easy installation, removal, and servicing of poles, using high-strength straps and a wire rope system for lifting, and adjustable leg braces for stability, enabling operation by one or two persons without the need for cranes or cherry pickers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy equipment like cranes or cherry pickers is used to install and remove light poles, then the pole installation and removal can be achieved, but the equipment cost and complexity increase significantly
Solution Approach 1:
The apparatus is divided into separate functional components: a base bracket that attaches to the pedestal, a mast that provides lifting height, and a hoist mechanism. This segmentation allows each component to be optimized independently and facilitates easy transportation and assembly without requiring complex integrated heavy equipment
Solution Approach 2:
The apparatus introduces an intermediary lifting system between the ground and the pole, using a hoist mechanism with cable and pulley system attached to the mast. This intermediary mechanism enables pole installation and removal without directly using heavy cranes, reducing equipment complexity while maintaining operational capability
2Power
If heavy equipment is used for pole installation, then the lifting capability is sufficient, but the transportation and storage become difficult
Solution Approach 1:
By segmenting the apparatus into a compact base bracket and a telescopic or sectioned mast, the system maintains sufficient lifting power through the hoist mechanism while reducing the overall footprint for transportation and storage. The mast can be collapsed or disassembled into manageable sections
Solution Approach 2:
The mast is designed to be extendable and collapsible, allowing it to provide sufficient height and lifting power during operation while being compact for transportation and storage. This dynamic structure adapts between operational and transport states
3Productivity
If traditional pole installation methods are used, then poles can be installed on pedestals, but the process requires multiple heavy machines and is time-consuming
Solution Approach 1:
The apparatus merges multiple functions into a single integrated system: the base bracket provides stable attachment to the pedestal, the mast provides lifting height, and the hoist mechanism provides the lifting force. This combination eliminates the need for multiple separate heavy machines while maintaining installation capability and improving speed
Solution Approach 2:
The apparatus is designed to be universally applicable to various pole sizes and pedestal types through adjustable components and attachment mechanisms. The base bracket can accommodate different pedestal dimensions, and the mast height can be adjusted, allowing one apparatus to perform multiple installation tasks without requiring specialized equipment for each case
