Product Introduction
The TRANFOVIA transformer coil assembly platform surrounds the coil with four height-adjustable operating sections, giving technicians safe access throughout complete coil assembly. Its fixed floor-mounted structure supports a total platform load of 1.5 tons, while the expandable central cover adapts to coil diameters from Φ1000 to Φ3600 mm.
A Fixed Workstation Built Around the Coil
Complete transformer coil assembly requires technicians to work around a large central workpiece at several heights. A conventional movable work platform provides access from one or two sides, but it does not create a continuous working area around the coil.
This platform uses four fixed columns with operating tables, ladders, guardrails and an integrated electrical control system. The worktables rise around the coil, and the central cover expands or retracts to keep the opening close to the coil diameter. This configuration is designed for coil fitting, connection, positioning and inspection.
How the Platform Adapts to the Assembly Process
- Height Adjustment Around the Coil The motor, worm gear reducer and screw lifting system raise the operating sections through an elevation range of 800-4500 mm. Technicians can move the working level as coil assembly progresses from the lower end to the upper connection area.
- Expandable Central Cover The platform opening adjusts from Φ1000 to Φ3600 mm. Keeping the cover close to the workpiece reduces the open gap around different coil diameters and provides a more practical working edge.
- Four-Side Working Access The four-column arrangement creates access around the coil instead of limiting the operator to a single side. Ladders and guardrails support entry and protected work at elevated positions.
- Fixed Floor-Mounted Structure The platform is anchored directly to the workshop floor and does not need to travel between stations. The fixed layout prioritizes stability and repeatable positioning during complete coil assembly.
Position-Holding and Operator Safety
The lifting system uses both electrical and mechanical self-locking protection. The purpose is not only to reach the required height, but also to hold the operating platform safely when technicians are working around the coil.
- Electrical and mechanical double self-locking for reliable stopping at intermediate working heights.
- Guardrails around the elevated work area and ladders for controlled operator access.
- Expandable cover adjustment to reduce the open space around the coil.
- Fixed ground installation to prevent unintended platform movement during assembly.
- Maximum load of 375 kg for each individual operating plate within the total 1.5 ton platform rating.
Application
- Complete assembly of large transformer coil sets.
- Installation and alignment of concentric coil sections.
- Lead connection, insulation fitting and dimensional inspection at different heights.
- Assembly routes requiring access around the full coil circumference.
- Transformer factories using a dedicated, fixed coil assembly station.

FAQ
- What is the platform designed to assemble?
It is designed for complete transformer coil assembly, including fitting, alignment, connection and inspection around large coil structures.
- What coil diameter range can the central cover accommodate?
The expandable cover adjusts from Φ1000 to Φ3600 mm.
- How high can the operating platform rise?
The working elevation range is 800-4500 mm, with an elevation speed of approximately 0.5 m/min.
- What is the maximum platform load?
The total operating-platform load is 1.5 tons. Each individual operating plate is rated for a maximum load of 375 kg.
- Can the platform stop at different working heights?
Yes. The motorized screw-lifting system uses electrical and mechanical self-locking protection so the platform can stop and hold at the selected position.
- Is the platform movable?
No. It is installed directly on the workshop floor. The fixed structure is intended for a dedicated coil assembly station.
- How is it different from the movable transformer assembly platform?
This platform surrounds a coil with four fixed lifting sections and an adjustable central opening. A movable transformer assembly platform uses separate frames positioned beside the transformer body.
