Nameplate and winding diagram
The nameplate and connection diagram help establish identity, ratings, winding configuration, and other unit-specific data. Ask for legible photographs and confirm that the serial number matches the equipment being offered.
General arrangement drawings
Drawings support the review of footprint, clearances, terminal locations, accessory arrangements, and site interfaces. Request the correct drawing revision for the actual unit and its current configuration.
Testing and condition records
Ask which factory and field reports are available, when testing was performed, and whether the records relate to the offered equipment. For pre-owned equipment, request service history, maintenance information, and known repairs or modifications.
Shipping configuration and weights
Operating weight is not necessarily shipping weight. Request transport dimensions, shipping mass, accessory packing information, oil handling requirements, lifting points, and the manufacturer’s handling guidance where available.
Record gaps explicitly
Not every surplus unit has a complete archive. Make missing documents and any additional inspection or testing part of the buyer’s review and agreed scope. A catalog description does not replace engineering acceptance.
This guide supports project scoping. Unit-specific engineering review and the agreed project documents govern equipment acceptance and execution.
