Transformer Support Assembly for Crane-Free Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of non-functional power transformers is cumbersome and time-consuming due to the need for large mobile cranes and specialized transport, often resulting in delayed and inefficient replacement processes, which can lead to significant consequential damage and reliability issues in power networks.
Innovation Solution
An equipment support arrangement featuring detachable holding means and load stabilizers allows for simplified setup and unloading using a semi-low loader trailer with hydraulic lifting, eliminating the need for mobile heavy-duty cranes, and includes load receivers and damping elements for secure and vibration-damped support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile heavy-duty cranes are used to lift and move the transformer, then the transformer can be replaced, but the replacement process becomes time-consuming and logistically complex due to crane availability and travel time
Solution Approach 1:
The patent introduces holding means as an intermediary component that attaches to the transformer and interfaces with load receivers on the trailer. This mediator enables direct loading/unloading without requiring crane intervention, eliminating the time loss associated with crane positioning and operation while maintaining reliable transformer replacement
Solution Approach 2:
The holding means are pre-attached to the transformer before transport, and the load receivers are pre-positioned on the trailer. This preliminary preparation allows the transformer to be quickly loaded or unloaded by simply lowering or raising the trailer bed, eliminating the need for time-consuming crane operations during the actual replacement moment
2Ease of operation
If mobile heavy-duty cranes are deployed for transformer replacement, then the transformer can be moved, but the device complexity and logistical requirements increase significantly
Solution Approach 1:
The holding means serve as a simple intermediary attachment system that connects the transformer to the trailer's load receivers. This eliminates the need for complex crane operations and specialized heavy-lift equipment, significantly reducing device complexity while maintaining ease of operation through straightforward attach-detach procedures
Solution Approach 2:
The transformer equipped with holding means can be directly loaded onto and unloaded from the trailer without external crane assistance. The system serves itself by using the trailer's own hydraulic lifting capability to perform the loading/unloading function, eliminating the need for additional complex equipment
3Reliability
If traditional crane-based methods are used, then transformers can be handled, but the process requires specialized transport equipment and coordinated logistics that delay replacement
Solution Approach 1:
The holding means and load receivers create a direct interface between the transformer and trailer, eliminating the need for crane-mediated handling. This intermediary system enables immediate loading and unloading operations, dramatically increasing replacement speed while maintaining the reliability needed for power network operations
Solution Approach 2:
The patent skips the entire crane operation phase by using direct trailer-based loading. The transformer is rapidly transferred from its transport position to the installation site by simply lowering the trailer bed, rushing through what would traditionally be a time-consuming multi-step crane operation process

AI summary
The application relates to a support arrangement for electrical equipment (2), in particular a transformer or power transformer, comprising several holding elements (3a, b, c, d) arranged on the equipment itself, and a support arrangement with several load cells (4a, b, c, d), in particular four column-like support feet, wherein the respective electrical equipment (2) is placed in its final position with the holding elements (3a, b, c, d) on the load cells (4a, b, c, d) and/or, after being placed, rests and is arranged at least partially between the load cells (4a, b, c, d). The application also includes a method for erecting electrical equipment (2) by means of the aforementioned support arrangement. The use of load cells (4a, b, c, d), in particular drop boxes, for erecting a transformer or power transformer is also the subject of the application.
