Transformer Core Stacking and Turning Table

Product Introduction

The TRANFOVIA transformer core stacking and turning table provides one coordinated platform for horizontal core stacking and crane-assisted turning into the vertical assembly position. Its modular table layout can be matched to three-limb or five-limb cores, while the no-pit structure reduces workshop modification and simplifies installation.

From Horizontal Core Stacking to Vertical Assembly

Large transformer cores are normally stacked in a horizontal position, but the completed core must be turned upright for subsequent assembly. Moving the core between separate stacking and turning stations increases lifting operations, floor-space demand and the risk of distortion during handling.

This equipment keeps the core on the same modular platform from the beginning of lamination stacking through the 90-degree turning operation. The workshop crane supplies the lifting force, while the turning beams, synchronized table sections and supporting outriggers guide and stabilize the movement.

Structural Design for Core Protection

• Synchronized Turning The table sections are designed to move together during the lift, helping reduce uneven support and limiting distortion of the stacked core.
• Controlled Table Deformation Overall worktable deformation during turning is kept below 3 mm, supporting a more predictable turning path for medium and large transformer cores.
• Vertical Position Control The vertical deviation between the stacking table and turning beam is kept below 2 mm before and after turning, helping maintain the required assembly orientation.
• Welded Steel Structure The load-bearing structure uses hot-rolled sections or low-carbon steel welding to provide the rigidity required for core stacking and turning.
• Machined Reference Surfaces Key positions are mechanically machined to maintain flatness and alignment across the modular table sections.
• Stress-Relief Treatment Welded structures receive aging treatment to reduce residual stress and support long-term dimensional stability.
• Finite Element Verification The structural design is checked through finite element analysis to verify strength and rigidity before manufacture.
• Anti-Overturn Outriggers Longitudinal beams include extendable outriggers that stabilize the system after the core has been turned upright.

FAQ

1. What is a transformer core stacking and turning table used for?

It provides a horizontal surface for stacking the transformer core and then supports the same core during crane-assisted turning into the vertical assembly position.

2. Does the table require a pit or special foundation?

No. The structure is designed for floor installation without a dedicated pit, reducing civil work and simplifying workshop integration.

3. How is the core turned upright?

The workshop crane supplies the lifting force while the turning beams and synchronized table sections guide the core through the 90-degree movement.

4. Can it be configured for both three-limb and five-limb cores?

Yes. Three-limb cores use three platform sections, while five-limb cores use five platform sections.

5. Can the core be turned with the upper yoke already installed?

Yes. The table supports production routes with the upper yoke installed before turning as well as routes where the upper yoke is added later.

6. How is deformation controlled during turning?

The welded structure, machined reference surfaces, synchronized table sections and structural verification limit worktable deformation to less than 3 mm during the turning operation.

7. What prevents the upright core from overturning?

Extendable flip outriggers on the longitudinal beams provide additional support after the core reaches the vertical position.
