MOVING IN AND INSTALLING TRANSFORMERS

Three to 52 tonnes on a few square metres: we move transformers into data centers, substations and industrial buildings – by skidding track, machine skates or crane – set them, align them and hand them over ready for connection. And we get them out again, even from the basement.

A TRANSFORMER RARELY FITS THROUGH THE DOOR IT IS MEANT TO GO THROUGH

Transformers for data centers and industry – from the 750 kVA cast-resin transformer weighing three tonnes to the 52-tonne transformer on railway rails – end up in a transformer cell built precisely for them, with a few centimetres of clearance to the wall. The route there leads through access openings, over shafts, through plant corridors and into basements. Exactly this route is our work: moving transformers in, skidding, setting, aligning, anchoring and handing them over for electrical connection.

We work with skidding tracks, machine skates, hydraulic jacks, mini cranes and mobile cranes – depending on whether the transformer arrives on a low-loader, is standing in the yard or has to come out of the basement. Every lift is calculated in advance as a lift plan and released by our own lifting contact; on data center sites according to the general contractor's RAMS and permit. Most recently we moved two transformers of around 52 tonnes each in one day from the heavy-duty low-loader via the skidding track into their cells – over 100 tonnes in total, with two mechanics and one lifting supervisor.

Unsere Rolle ist die mechanische: Einbringung, Aufstellung, Ausrichtung, Verankerung und Anbau von Lüftern, Gehäusen und Zubehör. Anschluss, Prüfung und Inbetriebnahme übernehmen wir mit eigener Elektrofachkraft – Mechanik und Elektrik aus einer Hand, einschließlich Lasttest und Übergabe.

FOUR REASONS WHY PLANNERS AND GENERAL CONTRACTORS CALL US IN

Moving in to finished buildings

New construction is the exception. Usually the building is finished, the routes are tight, and the transformer has to go through an opening nobody planned for it. We measure routes, load-bearing capacities and slewing radii in advance and bring the lifting equipment that fits through the door.

Skidding track and machine skates

From the low-loader via the skidding track into the transformer cell, without a crane touching the building: support and level the track, pick the transformer up straight from the trailer, push it with hydraulic cylinders step by step onto the building rail, lift, remove the track, set down. Carries 52 tonnes and needs no headroom – for halls and basements that no crane can reach into.

Removal from the basement

In a transformer replacement or dismantling, the old transformer has to come out first – from a cell it entered years ago with the shell construction. We dismantle, pull out, lift out through a shaft or opening and bring the new one in by the same route, in the same shutdown window.

Lifting operations under our own responsibility

Lift plan, lifting accessories, exclusion zones, release of every lift: our lifting contact bears responsibility for the lifting operation – a point that general contractors in data center construction expressly demand. Documentation in German and English.

WHAT WE TAKE ON WITH TRANSFORMERS

Vom Abladen bis zur betriebsbereiten Übergabe – je nachdem, wo Ihre Leistung endet und unsere beginnen soll.

Unloading and interim transport

From the low-loader with a mobile crane or hydraulic jacks, transport on the premises with machine skates, platform trolleys or our own machine transporter – also for transformers that only go into the cell weeks after delivery.

Moving in

Via skidding track, access opening, shaft or crane: route and lifting equipment selected according to weight, dimensions and building. Protecting floor slabs and door thresholds, securing routes, moving the transformer without tipping moment.

Setting, aligning, anchoring

Bringing it into position in the transformer cell, setting it on vibration dampers or foundation, aligning, anchoring. Checking clearances to the wall, ventilation paths and accessibility for maintenance and connection.

Attachments and accessories

Mechanically fitting fans, protective enclosures, temperature sensors, terminal covers and connection busbars, installing cell cladding and doors – from pre-assembly in our workshop or on site.

Handover to commissioning

Removal and transformer replacement

Dismantling the old transformer, pulling it out of the cell, basement or lower floor and lifting it out, preparing it for removal or recycling – and bringing in the new one in the same window. During ongoing operations, when the second feed carries the load.

THREE SITUATIONS, THREE ROUTES INTO THE CELL

New installation, replacement in an existing building or dismantling – the transformer is the same, the route is not. The choice of lifting equipment is decided by the building, not by the catalogue.
New installation

Shell open, crane reaches the cell

The simplest case: access opening still open, mobile crane places the transformer directly in front of or in the cell. Our job is the lift plan, slinging, guiding, setting and aligning – and coordination with the shell construction so that the opening is only closed after us.
Replacement in existing building

Building finished, cell occupied

The old transformer has to come out, the new one has to go in, the shutdown window is short. Skidding track and machine skates through finished corridors, floor protection, removal via shaft or door. Both movements in one window, often at night or at the weekend.
Dismantling

System out of service, route to the outside

In the case of decommissioning or conversion we move transformers out of basements and lower floors, dismantle attachments and prepare them for removal or recycling – documented, with labelling for possible reuse.

MOVING IN TRANSFORMERS: STRAIGHT ANSWERS

How do you get a transformer into a finished building?

By the route that exists: access opening, plant corridor, shaft or door. On the floor we move with a skidding track or machine skates, vertically we lift with a mobile crane, mini crane or hydraulic jacks. Beforehand we measure routes, load-bearing capacities and slewing radii and calculate the lift plan – only then does the low-loader come.

Do you also handle the electrical connection and commissioning?

Ja. Wir bringen ein, setzen, richten aus, verankern und montieren Anbauteile – und übernehmen Anschluss, Prüfung und Inbetriebnahme mit eigener Elektrofachkraft. Auf Rechenzentrumsbaustellen begleiten wir Anschluss und Lasttest bis zum Green Tag.

Which transformers do you move in?

Most recently cast-resin transformers for data centers with 750 to 2,500 kVA, 20 kV to 415 V and three to seven tonnes in weight, including 415/415 V isolating transformers, as well as two transformers of around 52 tonnes each via the skidding track – plus oil transformers for substations, industrial plants and utilities. The decisive factors are weight, centre of gravity and dimensions; we select the lifting equipment accordingly.

Can you get an old transformer out of the basement?

Yes. In a transformer replacement or dismantling we remove attachments, pull the transformer out of the cell, move it out via shaft, opening or stairwell and prepare it for removal – in the same window in which the new one comes in.

What is a skidding track and when do I need one?

A skidding track is a hydraulic rail system: the transformer is set from the low-loader directly onto the track and pushed with hydraulic cylinders piece by piece into the cell – without a crane at the building. It needs no headroom, carries 52 tonnes and closes the gap between the low-loader and the building rail in the transformer cell. It is the right route when no crane can reach the cell, the floor has to be protected or several transformers go one after another into a row of cells. The real work is supporting and levelling the track: a 52-tonne load that runs crooked into a room can no longer be straightened.

Do you work during ongoing operations?

Yes, when a second feed carries the load. Transformer replacement and moving in at a live data center are our everyday work: with permit, exclusion zones, shutdown window at night or at the weekend and documentation in German and English.
