transformer Active Part Assembly Platform
During the manufacturing process of large power transformers, the assembly of the “Active Part” is the most critical and high-risk stage in the entire production chain. When handling cores and windings that weigh anywhere from several tons to over a hundred tons, relying on conventional overhead cranes or makeshift scaffolding is not only highly inefficient but also poses immense hidden risks, including falls from height and structural deformation of components.

BEST™ Active Part Assembly Platform
BEST™ provide world-class transformer Active Part assembly tooling and elevating platforms. From the safe 90-degree upending of the core to the stable support required for high-level lead wire welding, our equipment is purpose-built to meet the most stringent HSE (Health, Safety, and Environment) standards. We empower you to achieve 100% safety and ultimate assembly precision in the manufacturing of UHV (Ultra-High Voltage) and heavy-duty transformers.

1. Active Part Assembly Lifting Platform
BEST™ Transformer Active Part Elevating Platform is purpose-built for lead wire connections, insulation wrapping, and tap changer installation, providing a rock-solid “ground-level” workspace at height for your large active part assembly. We offer both the classic hydraulic scissor-lift configuration and the multi-column mechanical screw drive system—the top-tier solution preferred in high-end European and American markets.
-
Core Advantage: The mechanical screw-driven models feature a “Dual Mechanical Self-Locking” mechanism (Zero Creep). Whether in the event of a power outage or during prolonged static suspension, the platform is completely immune to the gradual drifting or creeping caused by hydraulic micro-leaks, guaranteeing 100% safety for operations at height.
-
Scope of Application: Final assembly workshops for medium and large power transformers with heights exceeding 2 meters.
2. Core Stacking and Tilting Table
Once the horizontal lamination stacking of large transformer cores is complete, they must be positioned upright for winding assembly. Engineered with a heavy-duty welded steel structure and high-thrust multi-stage hydraulic cylinders, this series of equipment smoothly upends cores weighing from tens to over a hundred tons by a full 90 degrees. It completely eliminates the need for hazardous overhead crane lifting, achieving a seamless, zero-deformation upending process for heavy-duty active parts.
-
Core Advantages: Completely eliminates the sliding and deformation of silicon steel laminations typically caused by conventional overhead crane lifting. This vital protection preserves core integrity, minimizes no-load losses, and guarantees 100% operator safety.
-
Scope of Application: Core manufacturing for medium to large power transformers ranging from 35kV to 500kV.
Why choose our transformer assembly platform?
-
The Underlying Confidence of Heavy-Duty Engineering: Zero Compromise on Structural Integrity. We refuse to settle for lightweight alternatives. Our platform chassis features a heavy-duty, deep-foundation steel structure that has undergone rigorous Finite Element Analysis (FEA), ensuring rock-solid stability when operating at maximum rated capacities.
-
100% Bespoke Engineering: No two transformer workshops are exactly alike. We offer one-on-one 3D modeling and tailored manufacturing based strictly on your specific parameters, including the maximum active part weight, maximum active part height, and your facility’s existing foundation conditions.
-
World-Class Safety Standards: Our electrical and hydraulic systems are fully compliant with CE and UL standards. Each unit comes standard with anti-fall safety locks, overload early-warning systems, and a one-touch emergency stop, safeguarding every lifting operation in your workshop.
Selection Guide FAQ: How to Choose the Right Assembly Platform?
Q1: My transformers reach up to 4 meters in height, and workers require frequent up-and-down access. Which type is the most suitable?
A: If you have an ample budget and demand the most stringent safety standards, we highly recommend the multi-column mechanical screw-driven elevating platform. Its mechanical self-locking mechanism guarantees absolute safety for workers operating at a height of 4 meters, completely eliminating any risk of downward drifting or creeping.
Q2: What load capacities do your core upending tables support?
A: Our hydraulic core stacking and upending tables are available in a comprehensive range of standard models, covering load capacities from 5 tons to 200 tons. Please contact our technical team to request a detailed selection matrix.
Q3: Do these assembly platforms require a foundation pit?
Content goes here A: It depends on the specific model. Core upending tables are typically installed directly on flat ground. For elevating assembly platforms, we offer both surface-mounted (with ramps) and pit-mounted options. If you prefer the platform to be completely flush with the workshop floor when lowered—allowing for the obstacle-free access of air caster transporters or forklifts—we highly recommend the pit-mounted installation. We will provide detailed foundation construction and load-bearing drawings in advance…
Q4: Our workshop has limited overhead crane clearance. Can the lifting height of the assembly platform be customized?
A: 100% yes. All active part assembly platforms are custom-tailored. Our engineers will precisely customize the platform’s lifting stroke and chassis dimensions based on your maximum active part height, the clearance limit of your workshop’s overhead crane, and the safe working space required for your operators, ensuring not a single inch of your workshop space is wasted.
Q5: Are the daily maintenance costs for mechanical screw-driven elevating platforms higher than those for hydraulic ones?
A: On the contrary, their daily maintenance is much more effortless. Hydraulic systems require regular replacement of hydraulic oil and filters, as well as inspections of seals to prevent micro-leaks. In contrast, the mechanical screw drive system is a purely mechanical, rigid structure. Daily maintenance only requires periodic lubrication (greasing) of the lead screws and guide rails. Long-term operation is cleaner, more stable, and features extremely low hidden maintenance costs.
Q6: What is the typical lead time for a customized heavy-duty active part assembly platform?
A: Depending on the load capacity and complexity of the equipment, the standard manufacturing cycle is typically 45 to 60 days after drawing confirmation. To accelerate your internal procurement approval process, we can provide a detailed 3D layout and preliminary proposal for your evaluation within 48 hours of receiving your requirements.
