Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.

What makes a Maddox Transformer different
Maddox Transformer is a Texas manufacturer and rebuilder known for distribution and power transformers, including mobile units. Its distinguishing detail is rebuild and new-build work documented to the test sheet.
For an owner in North Carolina, that documentation helps establish what was built, changed or tested.
A Maddox rebuild needs to be read as an individual machine, not just a brand name on a tank. The rebuild date, winding information and test results should agree with the installed configuration.
Whether the core is original is a separate question that deserves a documented answer.
Local reality
Maddox Transformer vintages and models in the state
For a Maddox unit leaving a Greensboro plant or a Raleigh facility, distinguish the original manufacturing date from the rebuild date. Rebuilt equipment can carry both histories.
Photograph every plate and attached rebuild label rather than assuming the newest date describes the age of the entire assembly.
Distribution, power and mobile Maddox units require different descriptions for removal planning in North Carolina. Record the actual kVA, primary and secondary voltages, cooling designation and enclosure arrangement.
A trailer-mounted unit also needs chassis details; a stationary unit needs tank dimensions and the location of its lifting points.
Around the site
Where they fail
Cooling fans wear, and a Maddox unit with forced-air cooling needs more than a glance at the radiator bank. Record seized motors, damaged blades, missing guards and evidence of failed controls.
A fan that does not run can limit cooling even when the tank shows no obvious damage.
A rebuild date is not a failure diagnosis, but it establishes an important point in the Maddox service history. Compare later trips, leaks or overheating reports with that record.
Describe the observed condition precisely: oil at a gasket, a cracked bushing or a fan motor that stalls.
Where it sits
The nameplate and the paperwork
The Maddox nameplate photograph should show the serial number, kVA, voltages, phase, impedance and cooling information clearly enough to read. Include any separate rebuild plate.
For equipment disconnected during a North Carolina demolition project, capture those details before dust, wrapping or access restrictions hide the identification.
Keep the rebuild record and test sheet together, with serial numbers visible on both. We check whether the core is original and what the rebuild documentation actually establishes.
If records are missing, identify the gap rather than treating an old test sheet as proof of present operating condition.
On the ground
Inspection priorities
Inspection of a Maddox rebuild starts with agreement among the plate, rebuild record and test sheet. Then check bushings, radiators, gasket seams and cooling fans.
Document damage without opening energized compartments; internal access and electrical testing belong to qualified personnel working under the site's isolation and safety procedures.
For a mobile Maddox unit, inspect the transformer and its transport assembly as separate items. Photograph cable terminations, grounding connections, radiator clearance and chassis condition.
At a Charlotte staging yard, a clear exterior survey can reveal loading obstacles, but it cannot establish winding condition or replace documented electrical tests.
Local reality
Getting a Maddox Transformer out of the building
Removal planning for a Maddox unit inside a Durham plant starts with the actual exit route. Measure door openings, overhead obstructions and turns between the transformer and the loading area.
Identify removable radiators or accessories from drawings and qualified inspection, not from assumptions about how another rebuild was assembled.
Before a lowboy reaches the North Carolina site, confirm documented weight, lifting provisions and crane access for the Maddox tank. The lift plan must account for the equipment's actual configuration.
A mobile unit may need chassis evaluation instead; wheels alone do not establish that it is ready for transport.
Around the site
How the brand affects what we pay
The Maddox name identifies a manufacturer and rebuilder, but it does not settle the assessment of a particular unit. The rebuild record, test sheet and original-core status carry more detail than the badge.
Cooling fan condition and documented service problems help distinguish an intact machine from a failed assembly.
For North Carolina owners, the useful submission is a matched set of Maddox identification photographs, rebuild documents, condition notes and removal details. We buy equipment in used, surplus, failed and obsolete condition.
Missing paperwork should be stated plainly, alongside any known core replacement, fan failure or access restriction.

Questions
Straight answers
Equipment types
Can you buy a Maddox unit without rebuild records?
Yes. Missing rebuild records do not automatically exclude a Maddox unit from assessment. Provide readable nameplate photographs, any rebuild label, known service problems and the North Carolina location. State whether the test sheet is missing and whether the original-core status is known.
Service area
Which dates matter on a rebuilt Maddox transformer?
Record the original manufacturing date and the rebuild date wherever they appear. They describe different events in the unit's history.
Payment
Do worn cooling fans prevent a Maddox assessment?
No. We buy failed Maddox equipment as well as used and surplus units. Describe which fans are affected, whether motors stall and whether guards or blades are damaged. Include cooling-control information if documented, without energizing the equipment merely to demonstrate the fault.
