TransformerAssembly Platform

Product Introduction

A transformer assembly platform is an adjustable working platform used around a medium or large transformer during coil sleeving and upper-yoke installation. It allows operators to work at the correct height while low-voltage coils, high-voltage coils, insulation components and the upper core yoke are installed.

Unlike a fixed coil assembly platform, this design uses two independently movable frames arranged face to face. Each side can be repositioned vertically and horizontally to follow the transformer dimensions and the assembly stage.

Applications of the Transformer Assembly Platform

• Sleeving finished low-voltage coils over the transformer core limbs from the top.
• Sleeving high-voltage coils over the installed low-voltage coils.
• Installing the upper yoke after the coil assemblies are in position.
• Adjusting insulation, clearances, lead exits and coil alignment during transformer assembly.
• Providing elevated access for medium and large transformer assembly operations.

Main Features

• Independent vertical and horizontal adjustment. The two frames can move separately so each side can be matched to the transformer height, coil position and current assembly task.
• Motorized screw lifting system. The standard lifting arrangement combines an electric motor, worm gear reducer and lead screw for controlled platform elevation. Hydraulic cylinder lifting can be supplied as an alternative.
• Electrical and mechanical self-locking. Dual self-locking protection allows the working platform to stop securely at the selected height.
• Extendable working plates. Pull-out plates increase the usable working area near the transformer. Positioning pins secure the plates after extension.
• Ground and platform control stations. Control stations are installed at ground level and on the working platform. Interlocking helps prevent conflicting or accidental operation.
• Brake-type movement and lifting motors. Braking motors support controlled stopping during platform travel and lifting.
• Integrated tool power supply. Power sockets in the middle of the platform allow operators to use common electric tools without long temporary cables across the work area.
• Work-area lighting. Each end is equipped with a 150 W crank-arm lamp, with additional lighting below and above the worktable to improve visibility around the transformer assembly area.
• Polyurethane travelling wheels. The wheels provide the mechanical strength required for platform movement while reducing floor damage and static accumulation.
• Safety-critical component inspection. Components associated with safety requirements receive heat treatment and flaw detection.

Technical Parameters

FAQ

1. What is the transformer assembly platform mainly used for?

It provides adjustable access for transformer assembly, especially sleeving finished low-voltage and high-voltage coils over the core limbs and installing the upper yoke.

2. Does the platform lift the transformer coils?

The platform positions the operators and tools. The coils and upper-yoke parts should be handled by suitable workshop lifting equipment and approved lifting fixtures.

3. Can the two sides move independently?

Yes. The two face-to-face frames can be adjusted independently in height and horizontal position to match different transformer dimensions and assembly stages.

4. What load capacities are available?

The available platform load options are 2, 3, 5, 10, 15 and 20 tons. The final configuration depends on the required working area and operating load.

5. How is the platform lifted?

The standard system uses a motor, worm gear reducer and lead screw. Hydraulic cylinder lifting is available as an alternative configuration.

6. How is the platform secured at working height?

Electrical and mechanical self-locking systems provide dual protection so the platform can stop at the selected position.

7. Is the worktable size fixed?

No. The worktable dimensions are designed around the transformer size, required access area and workshop layout.

8. What information is required for a quotation?

Provide the transformer drawing, working heights, platform load, required travel, workshop layout, crane arrangement and applicable safety requirements.
