How to Identify an Old Car Lift Model

If you just bought a shop, inherited a garage, or found a lift buried under years of parts washer sludge, figuring out how to identify old car lift model information is the first real problem you’ll hit before you can order parts or get it inspected. Old data tags fade, get painted over, or fall off entirely, and a lot of lifts from the 70s through the 90s changed hands between manufacturers so the name on the column may not even be the current parts source. We deal with this constantly at Auto Lift Services, based in Ames, and there’s a reliable process for tracking down what you actually have.

Start With the Data Tag, Even If It’s Damaged

Every lift built for the U.S. market since the mid-1990s was required to carry a data tag or nameplate somewhere on the unit, usually on a column base, the power unit housing, or a crossbeam. This tag typically lists a manufacturer name, model number, serial number, capacity, and sometimes a manufacture date. Learning how to identify old car lift model equipment almost always starts here, even when the tag is scratched, rusted, or partially peeled.

If the tag is unreadable, don’t scrape or repaint over it before photographing it in raking light — sometimes stamped or embossed characters show up better in a low-angle photo than to the naked eye. Check underneath paint drips too; a lot of shop owners have painted their lifts over the decades and buried the tag entirely. If there genuinely is no tag left, check for a second location — many manufacturers stamped a duplicate serial number into the base casting itself, separate from the removable tag. That stamped number often survives even when the sticker doesn’t, and it’s one of the most reliable ways to identify old car lift model details when everything else has failed.

Look at the Casting and Weld Style

Once the tag is gone, the physical build of the lift itself becomes your evidence. Older Rotary lifts, older Bendpak-adjacent designs, and various independent brands from the 70s-90s all used distinct base casting shapes, arm restraint styles, and column cross-sections. A two-post lift with a rectangular column and exposed cable sheave at the top reads very differently than a later enclosed-column design. These details won’t give you an exact model number by themselves, but they narrow the era and family fast.

Weld patterns matter too. Lifts from certain manufacturing runs used visible stitch welds along the column seam, while others used continuous welds or bolted plate construction. If you’re trying to identify old car lift model equipment and you’ve got some mechanical background, comparing your unit’s carriage design, arm shape, and pad style against manufacturer archive photos (many of which we can pull up on request) will usually get you into the right family within a few minutes.

Check the Power Unit and Control Box

The hydraulic power unit is often a different age or even a different brand than the lift structure itself, since power units get swapped out over decades of service. Still, the power unit’s own tag, motor nameplate, and valve block casting can tell you a lot. A motor with an old-style frame size and a specific voltage/phase configuration often points to a manufacturing decade even when the lift’s own tag is long gone.

The control box wiring and switch style is another clue. Toggle switches wired directly to a contactor suggest an older design, while a sealed membrane panel points to something newer. None of this alone confirms a model number, but combined with the casting shape and column style, it builds a strong circumstantial case. We’ve had customers send us three or four photos — tag, base casting, power unit, control box — and between those we can usually land on the correct parts family even with zero legible tag information.

Measure It — Numbers Don’t Lie

When visual identification stalls, take real measurements. Overall lifting height, distance between columns, arm reach at full extension, and rated capacity (if stamped anywhere) all narrow the field dramatically. A two-post lift with a shorter overall height and a lower rated capacity is almost certainly an older or lighter-duty design than a tall commercial unit rated for heavier trucks.

Column spacing is especially useful because manufacturers were fairly consistent within a given model line. If you measure center-to-center column spacing and compare it against published specs for candidate models, you can usually eliminate several possibilities immediately. This is one of the fastest ways to identify old car lift model equipment when there’s genuinely nothing left to read on the machine itself, and it takes ten minutes with a tape measure.

Search by Cable, Cylinder, or Arm Part Numbers

If your lift still has its original cables, cylinder, or arm restraint hardware, those parts sometimes carry their own stamped part numbers separate from the lift’s data tag. A cylinder with a legible casting number, for instance, can be cross-referenced against known parts catalogs even if you have no idea what brand the overall lift is. The same goes for equalizer cables — length and end-fitting style are searchable clues.

This approach works especially well for lifts that changed hands between manufacturers, since replacement parts sometimes carry the part supplier’s numbering rather than the original builder’s. We keep cross-reference data for a wide range of older lift lines specifically because so many Iowa shops are running equipment that’s twenty, thirty, or more years old and the original paperwork is long gone.

Ask a Shop That’s Seen Thousands of These

Honestly, the fastest way to identify old car lift model information is often just to send photos to people who look at old lifts every week. We’ve walked customers through this exact process more times than we can count, and patterns jump out to someone with experience that aren’t obvious to a shop owner seeing their fortieth lift for the first time. If you’ve already tried the tag, casting, measurements, and part numbers and you’re still stuck, that’s when a phone call saves the most time.

For a deeper walkthrough of tag locations and serial number formats specifically, our guides on how to identify your car lift model and how to identify your car lift model serial number go into more detail on reading what’s actually stamped on the unit.

Know When It’s Time to Stop Chasing Parts and Replace It

Sometimes the identification process itself reveals the real answer: the lift is old enough, worn enough, or obscure enough that sourcing parts isn’t worth the effort anymore. If you’ve gone through casting comparisons, measurements, and part number searches and you’re still coming up short — or the lift turns out to be a discontinued line with no support — it may genuinely be cheaper and safer to replace it outright.

We cover that decision in detail in our piece on replacing an old car lift, including what signs mean a rebuild isn’t worth chasing anymore. Either way, knowing how to identify old car lift model equipment first is what lets you make that call with actual information instead of guessing.
