We lift transformers, switchboards, switchgear and electrical plant across Melbourne. Onto pads and bunds, into substations and switchrooms, out of plant rooms during upgrades, and in and out of buildings where the equipment has to travel further than the crane can reach.
These lifts are usually short. What makes them difficult is that the tolerance is tiny, the equipment is expensive and easily damaged, and the site is often congested and partly live.
This is the rule that matters most on transformer work, and manufacturers are unanimous about it.
Transformers are lifted from their designated lifting lugs. Not from bushings, not from radiator brackets, not from valve flanges, and not from whatever else looks like it might take the weight. Those components are not lifting points and were never designed to be, and using them damages equipment that costs a great deal more than the crane hire does.
Units above around two tonnes generally require a spreader beam rather than slings straight to the hook. The reason is straightforward. Slings pulled in at an angle apply horizontal compression to the lugs, and the lugs are designed for a vertical pull. Side loading them risks the welds.
The lift also has to stay vertical. Manufacturer manuals commonly limit how far a transformer may tilt during lifting, often in the order of fifteen degrees from vertical, and that limit exists for a physical reason. The core, coils, fuses, and switches inside need to remain immersed in the dielectric fluid. Tip the unit too far,r and they are not.
Forklifts are frequently prohibited outright, with manufacturers attaching no forklift decals to the tank. If you have been told to unload one with a forklift, check the nameplate and the manual first.
Send us the unit details and the manual if you have it.
Work inside an operating substation or switchyard leaves little room for error. Restricted access, live equipment, and hidden ground services create added constraints that must be considered before the crane is positioned.

Pad-mounted and kiosk substations lifted onto prepared pads and bunds, on new estates, commercial developments and network upgrades.
Larger units placed within substations and industrial sites, including replacements where the old unit comes out first.
Main switchboards, distribution boards, HV and LV switchgear lifted into switchrooms, plant rooms and prefabricated enclosures.
Standby generators, UPS units, batteries and associated plant lifted onto slabs, into plant rooms and onto roof decks.
Packaged substations, switchrooms and enclosures placed as complete units on prepared footings.
Existing transformers and boards removed during upgrades and decommissioning, with the replacement landed in the same attendance where possible.

Working inside an operating substation or switchyard? Call 0457 000 637 early, because isolation and permit lead times set these dates rather than crane availability.

From its designated lifting lugs only, never from bushings, radiator brackets, or valve flanges. Units above roughly two tonnes generally need a spreader beam so the slings pull vertically rather than compressing the lugs inward, and the lift must stay within the tilt limit the manufacturer specifies.
Frequently not. Manufacturers often prohibit it and attach no forklift decals to the unit, because the weight distribution makes stabilization unsafe. Check the nameplate and manual before assuming a forklift is an option.
Manuals commonly limit tilt during lifting to around fifteen degrees from vertical, with installed tilt held much tighter, often between two and four degrees. The limits exist because the internal core, coils, and switchgear must stay immersed in the dielectric fluid.
Because an installed tilt outside the specified limit shortens the life of the unit, the transformer also has to sit flush with no gaps between the base and the pad, and the cable entries have to align with the trench or conduit.
Switchboards are tall, thin, and rack easily. An uneven lift twists the frame, after which doors do not close properly, cubicles misalign, and busbar connections do not meet as designed. Keeping the board square through the lift matters more than the weight.
Absolutely. With articulated steering, a compact frame and no outriggers, a Franna operates in narrow laneways, congested sites and factories with limited head height where a slewing crane cannot set up.
Where the crane operates within the specified distances of live overhead or ground assets, yes. On substation and network sites,s that is common rather than exceptional, and we arrange it.
Where the site and the electrical program allow it, yes, and it is considerably cheaper than two attendances. The constraint is usually the isolation window rather than the lifting.

It depends on the unit weight and, more often, the radius. Substation and plant room work frequently forces the crane to stand well back from the landing position, which pushes the machine up in size for the same load.
Quoted on the crane size, the time on site including controlled placement, and whether spotters, permits and lift documentation apply. Call 0457 000 637 with the unit details and the site.
