Introduction
The Iron Core Stacking and Turning Table is a specialized machine designed for stacking and turning transformer cores, particularly for medium and large-size transformers. It helps manufacturers improve production efficiency, reduce labor intensity, and ensure safer core handling in transformer workshops.
In transformer manufacturing, the iron core assembly process usually follows core cutting and silicon steel lamination preparation. For manufacturers building a complete core production line, this equipment can work together with a Transformer Core Cutting Line to improve workflow efficiency.
This equipment supports stable stacking, controlled turning, and reliable positioning of transformer cores.
What Is an Iron Core Stacking and Turning Table？
An Iron Core Stacking and Turning Table is a dedicated machine used for:
- Transformer core stacking
- Core turning (flipping)
- Core positioning during assembly
It provides a stable working platform for assembling silicon steel cores and allows the core to be turned safely during production.
Typical applications:
- Power transformer manufacturing
- Medium and large transformer production
- Core stacking and turning processes
- Three-column and five-column core assembly
- Workshop core handling without heavy crane dependence
Compared with traditional crane-assisted methods, a dedicated turning table offers better stability, higher safety, and more controlled operation.
Machine Usage
The Iron Core Stacking and Turning Table supports the core stacking process, then assists in turning the core to the required position. This reduces risks caused by repeated lifting, manual adjustment, and unstable movement.
For transformer manufacturers, the machine enables a safer, more efficient, and standardized core assembly workflow.
Key Features
1. Modular Combination Structure
The platform uses a modular design that can be paired according to the transformer core window size. This provides strong adaptability for various core specifications, allowing one machine to handle multiple transformer models.
2. No Pit or Special Foundation Required
The equipment does not require a deep pit or poured concrete foundation. It can be placed directly on the workshop floor. This reduces installation cost and time.
3. Strong Turning Ability with Low Energy Consumption
The turning operation is driven by the workshop crane’s lifting force — no additional energy. This reduces both energy consumption and auxiliary equipment investment, offering a high cost-performance ratio.
4. Safe and Stable Turning Process
The turning process is synchronized and controlled, helping to prevent core deformation. For large cores, deformation during turning can affect assembly accuracy and final product quality. This equipment ensures reliable, stable flipping.
5. Adjustable Center Distance and Customizable Table Size
Center distance can be adjusted according to production needs. The worktable size can be custom-designed to match your core dimensions, workshop layout, and assembly process.
6. High Precision and Low Deformation
- Overall deformation during turning is controlled to less than 3 mm
- Verticality between the stacking table and flipping beam is controlled to less than 2 mm before and after turning
These precision controls ensure stable core positioning and reduce assembly deviation.
7. Finite Element Analysis for Structural Strength
The structure is designed using advanced software and verified by finite element analysis (FEA). The main frame is made of hot-rolled section steel or low-carbon steel welded construction, with aging treatment to reduce internal stress and improve long-term stability.
8. Flip Outriggers for Higher Safety
Longitudinal beams are equipped with flip outriggers. After the core is turned 90°, the outriggers can be extended to prevent instability or overturning. This is especially important for large, heavy cores.

Why Transformer Manufacturers Need This Equipment
Traditional core assembly often relies heavily on cranes and manual coordination, leading to:
- High labor intensity
- Low assembly efficiency
- Difficult core positioning
- Higher risk during turning
- Possible core deformation
- Inconsistent quality depending on operator experience
The Iron Core Stacking and Turning Table solves these challenges by providing a stable, modular, and controlled solution for core stacking and turning.
