Automated Tagline Control for Wind Turbine Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high costs and inefficiencies associated with manual control of wind turbine components during assembly, disassembly, or maintenance, particularly due to the large size of modern turbines and the need for specific rigging setups, lead to prolonged crane usage and increased operational expenses.
Innovation Solution
An automated tagline control system that includes a self-contained module with winches, a controller, and a power source, positioned between the crane and the wind turbine component, using guide members and sensors to automate the positional adjustment of components, reducing the need for manual labor and specific rigging configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control using taglines and service personnel is used, then the wind turbine component can be controlled during lifting, but the process becomes time-consuming and requires a large group of personnel
Solution Approach 1:
The patent replaces the manual mechanical control system with an automated control system that uses a winch, cable, and pulley arrangement controlled by a controller. This automation eliminates the need for multiple service personnel to manually coordinate tagline handling, directly resolving the contradiction between ease of manual operation and time consumption.
Solution Approach 2:
The automated control system enables the lifting operation to control its own component positioning without external manual intervention. The controller automatically adjusts the cable length and component position based on pre-programmed parameters or real-time feedback, making the system self-sufficient and eliminating dependency on large teams of workers.
2Reliability
If specific rigging arrangements are used for different wind turbine components, then each component can be lifted safely, but the change out of rigging prolongs crane usage
Solution Approach 1:
The patent designs a universal control system that can handle multiple different wind turbine components (blades, hub, nacelle, tower sections) using the same basic rigging arrangement. The system's adaptability comes from programmable control parameters and adjustable cable lengths rather than physical rigging changes, allowing one rigging setup to serve multiple functions across different component types.
Solution Approach 2:
The control system is designed to be dynamically adjustable through software parameters rather than fixed physical configurations. The controller can be reprogrammed for different component weights, dimensions, and lifting requirements, allowing the same physical rigging to adapt to different components without physical modification or replacement.
3Extent of automation
If a self-contained automated control system is used, then manual labor is reduced, but the device complexity increases
Solution Approach 1:
The patent integrates multiple system functions into a single self-contained control unit that combines the controller, winch motor, cable management, and sensing capabilities in one location. This consolidation reduces the overall system complexity by eliminating the need for separate control systems, power sources, and coordination mechanisms that would otherwise be dispersed across multiple components.

AI summary
A tagline control system for handling a wind turbine component during an operation on a wind turbine using a lifting apparatus. The tagline control system includes a tagline control module (74, 164) having a housing (80), at least two winches (126,128) disposed within the housing and each having a tagline cable (130, 132), a controller (146) disposed within the housing and operatively coupled to the at least two winches, and a power source (148) disposed within the housing (80) and operatively coupled to the at least two winches. A method of handling a wind turbine component during an operation on a wind turbine using the lifting apparatus includes coupling the tagline control module to the lifting apparatus and to a wind turbine component, and operating the tagline control system to effectuate the position of the wind turbine component.
