Wind Turbine Tower Section Sling Handling for Transport and Upending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transportation and erection of modern wind turbine towers are challenging due to their large size and weight, requiring complex and time-consuming processes involving multiple tools and frames.
Innovation Solution
A tool comprising two wheeled platforms and a frame that supports a sling, allowing for efficient handling and transport of wind turbine tower sections by spanning the distance between the platforms, thereby reducing the need for multiple frames and tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional frames and multiple tools are used for transporting and erecting tower sections, then the tower sections can be handled, but the process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple separate tools (frames, transport devices, erection equipment) into a single integrated handling device. This device includes a transport system with wheeled platforms and an erection system with outriggers and lifting mechanisms, all integrated into one cohesive structure that can perform both transportation and vertical positioning functions
Solution Approach 2:
The handling device is designed to perform multiple functions: it can transport tower sections horizontally on wheeled platforms, position them vertically using outriggers and lifting mechanisms, and secure them during both transport and erection phases. This multi-functional design eliminates the need for separate specialized equipment for each operation
2Reliability
If multiple frames are used to support tower sections during transport and storage, then the sections can be stabilized, but the attachment and detachment process requires substantial time and effort
Solution Approach 1:
The handling device is pre-configured with outriggers and lifting mechanisms that are ready for immediate deployment. The transport platforms are designed with pre-positioned attachment points and hydraulic systems that can quickly engage and disengage from tower sections, eliminating the need for time-consuming manual frame attachment and detachment operations
3Length of moving object
If tower sections are divided into smaller sections for transport, then they can fit vehicle limits, but the number of sections increases making assembly more complex
Solution Approach 1:
The handling device uses hydraulic systems with adjustable outriggers and lifting mechanisms that can dynamically adapt to different tower section configurations. This allows the same device to handle various section sizes and numbers, providing flexibility in how tower sections are divided and assembled without requiring specialized equipment for each configuration

AI summary
The present disclosure relates to tools and methods for handling a tower section of a wind turbine tower. A tool comprises a first wheeled platform, a second wheeled platform, and a frame. The frame comprises a first side portion, and a second side portion. The first side portion is attached to the first wheeled platform and is configured to support a first end portion of a sling. The second side portion is attached to the second wheeled platform and is configured to support a second end portion of the sling. The first and second wheeled platforms are separated along a horizontal direction.
