Figuring out how to identify your lift model and serial number is the first phone call we get from a lot of shop owners in Iowa, and honestly it’s one of the most important calls to get right. Order the wrong cable, arm pad, or hydraulic hose because you guessed at your equipment, and you’ve wasted money and downtime waiting for a return. We’ve been installing and servicing lifts across Iowa for years, and we can usually walk you through finding your model and serial number in a few minutes over the phone, no service call required.

Why You Need to Identify Your Lift Model and Serial Number Before Ordering Parts
Every lift manufacturer changes designs over the years — sometimes multiple times within the same product line. A Rotary SPO12 built in 2008 can use different arm restraint hardware than one built in 2018, even though the frame looks nearly identical from across the shop. If you order parts based on a guess or a general model family, there’s a real chance the part won’t bolt up, and you’ll be shipping it back while your bay sits empty.
This is exactly why we push every customer to identify your lift model and serial number before calling in a parts order. The serial number ties back to a specific manufacture date and production run, which tells us exactly which revision of arms, cylinders, cables, or locks your unit shipped with. It also matters for safety — if a lift is ever part of a recall or service bulletin, the manufacturer identifies affected units by serial number range, not just model name. We’ve caught more than one Iowa shop running equipment that needed an updated safety component simply because we asked for the serial number during a routine parts call. Skipping this step might save you two minutes on the phone, but it can cost you a week of downtime if the wrong part shows up. Take the extra time up front — it always pays off.
Where to Find the Serial Tag on Most Two-Post and Four-Post Lifts
On most two-post lifts, the serial tag is riveted or bolted to the base of one of the columns, usually behind the power unit or on the inside face where it sits low to the ground. You’ll often need to get down on a knee and use a flashlight, especially if the shop is dusty or the tag has picked up years of grease. On four-post lifts, check the inside of one of the column legs near the base, or along the runway near the front approach ramp — placement varies more by manufacturer than with two-post units.
If the tag itself is missing or too corroded to read, don’t panic — the frame casting sometimes has a stamped serial number as a backup, and older paperwork like your original installation invoice or state inspection sticker can also carry the information. This is one more reason we tell customers to identify your lift model and serial number and keep a photo of that tag somewhere easy to find, like a phone photo album or taped inside your shop office. A five-second photo now saves you crawling around the base of a lift again next year when you need another cable.
Reading a Rotary, Challenger, BendPak, or Atlas Nameplate
Every brand formats its nameplate a little differently, which is part of why customers get confused trying to identify your lift model and serial number on their own. Rotary and Challenger units (both part of the same commercial lineup we install across Iowa) typically list the model number, serial number, capacity rating, and manufacture date all on one plate, usually near the top. BendPak and Atlas home-garage lifts tend to place the model and serial closer together in a smaller font, sometimes on a sticker rather than a stamped metal tag, so those can fade faster in a heated garage with direct sunlight.
Look for the specific pattern of letters and numbers — Rotary and Challenger models often start with a two-letter prefix followed by numbers indicating capacity, while BendPak and Atlas use their own naming conventions tied to lift type and weight rating. If you’re staring at a plate with multiple numbers and not sure which one is the actual serial, take a photo of the entire tag and send it to us. We work with these brands daily and can usually tell at a glance which digits are the serial number versus the capacity rating or a date code, even from a blurry phone picture taken in a dim bay.
What to Do When the Tag Is Gone or Unreadable
It happens more than you’d think — a nameplate gets painted over during a shop refresh, sandblasted off during restoration, or simply rusts through after twenty years next to a bay door. If you can’t identify your lift model and serial number from the tag itself, we start working the problem from other angles. Column height, base plate shape, arm style, and power unit design all give us clues about the manufacturer and rough production era, even without a serial number in hand.
We’ll also ask about where and when the lift was purchased, since that narrows things down fast — a used equipment dealer or an auction record sometimes still has the original paperwork. In a few cases we’ve had to measure specific components, like arm pin spacing or cylinder bore, to narrow down the exact configuration. It’s more work than reading a tag, but we’ve never failed to get a customer the right parts eventually. If your lift came from a business that’s since closed or changed hands, we can also check our own service records if we’ve worked on it before, which happens often in Iowa’s tighter-knit shop community.
Using Your Model and Serial Number to Order the Right Replacement Parts
Once you identify your lift model and serial number, ordering parts becomes straightforward instead of a guessing game. Cables, hydraulic cylinders, arm restraints, locks, and even hydraulic hose lengths are often specific to a model year range, not just the general model family. Two lifts sitting side by side in the same shop, both labeled the same model number, can still need different cables if one was built a few years before or after a design change.
When you call us or use our online parts lookup, having the serial number ready lets us cross-reference our supplier catalogs immediately instead of asking you to measure and photograph components on the spot. This is especially useful for older Rotary and Challenger commercial lifts, where certain part numbers have been superseded multiple times over a long production run. We keep detailed cross-reference records for the brands we install, so a five-minute conversation with your model and serial number in hand usually gets you a confirmed, correct part order the same day.
Recording Your Lift Information Before You Need It
The best time to identify your lift model and serial number is right after installation, not months later when a cable snaps and you need a part overnight. We recommend every shop keep a simple equipment log — even a basic spreadsheet or notebook works — listing each lift’s model number, serial number, install date, and capacity rating. Tape a laminated copy near the power unit or keep it in your shop office where anyone on staff can find it quickly.
This habit pays off beyond parts ordering too. Insurance audits, OSHA inspections, and annual safety inspections all move faster when you can hand over model and serial information without crawling around a lift base while an inspector waits. We’ve seen shops save real time during inspections simply because they had this information printed and ready.

When to Call Auto Lift Services for Help
Sometimes the fastest way to identify your lift model and serial number is to just call someone who’s seen thousands of these tags. We install, service, and stock parts for every major lift brand across Iowa, and our team can usually identify a lift from a photo of the tag, the column shape, or even the arm style within a couple minutes. There’s no charge for a quick identification call, and it often saves you from ordering the wrong part twice.
If your lift is older, has a damaged tag, or was inherited from a previous shop owner, we’re happy to send a technician out to physically inspect and document the equipment as part of a service visit. We also keep records on lifts we’ve previously installed or serviced in Iowa, so if we’ve touched your equipment before, we may already have the model and serial number on file. For more detail on reading specific tag formats, our guide on how to identify your lift model serial tag walks through brand-by-brand examples, and our piece on how to find your lift model and serial number covers less common mounting locations for the tag itself.
