Used Lift Buying Guide: What We Inspect Before Anyone Buys

Every few weeks someone calls us from a farm auction, an estate sale, or a shop that’s closing down in some small Iowa town, standing next to a lift they can buy for a fraction of new money, asking whether it’s worth hauling home. That phone call is exactly why we put this used lift buying guide together. We’re Auto Lift Services, based in Ames, Iowa, and we install, service, and stock parts for every major lift brand in the Midwest — which means we’ve also been the ones called out to condemn plenty of bargains after the money already changed hands. A good used lift can be the smartest purchase a shop ever makes. A bad one is a pile of steel you can’t legally put a car on. The difference comes down to what you check before you write the check.

Start With the Serial Tag, Not the Price

The single most useful thing on a used lift is a legible data plate. Brand, model, capacity, serial number, and year — that’s your whole research path. With those five pieces of information we can tell you whether the manufacturer still exists, whether cables and cylinders are stocked or obsolete, and whether the design was ever ALI certified. Without them, you’re guessing, and guessing on a two-post is how people end up with a 9,000 lb column pair holding up a 7,000 lb truck.

We had a general repair shop northeast of Des Moines send us photos of a two-post they’d found for cheap. Nice paint, straight columns, arms all matched. No tag anywhere — someone had ground it off during a repaint years earlier. We couldn’t source carriage slide blocks because we couldn’t confirm the model, and the seller had no paperwork. They walked away and bought a used Rotary SPO with a readable plate instead, and that lift is still working today. Any honest used lift buying guide has to start here: a missing serial tag isn’t a minor cosmetic issue, it’s a permanent parts problem and an insurance problem. Photograph the plate before you photograph anything else.

Brands That Are Worth Buying Used

Not all used lifts age the same way. On the commercial side we tell people to look hard at Rotary and Challenger, because both have deep parts support, decades of installed base, and service documentation that actually exists. A Rotary SPO12 from the mid-2000s is a genuinely good buy if the structure is sound — we can get you cables, carriage components, cylinders, locks, and arm restraints without drama. Challenger CL10 and similar models are the same story. For heavy-duty work, PKS-style mobile columns hold value for a reason.

For home and hobby garages, BendPak and Atlas both show up on the used market regularly and both are supportable. Where we get cautious is the flood of unbranded or house-brand imports that were sold online for a decade and then vanished when the importer folded. The steel might be fine. The problem is that nobody makes a replacement cylinder or a matched cable set for it, so a single failure ends the lift’s life. That’s the core economics behind this used lift buying guide: you’re not buying steel, you’re buying continued access to wear parts. If you want a side-by-side on how that math compares to new equipment, our used vs new lift buying guide lays out the tradeoffs in more detail.

The Structural Inspection That Actually Matters

Cosmetics lie. Structure doesn’t. On a two-post, get down and look at the base plates and the anchor holes — cracked concrete around anchors, elongated holes, or shimmed columns tell you the lift was working under stress or was never installed level. Sight down each column for bow or twist. Check the carriage slide blocks for wear; if the carriage rocks in the column when you push it, the blocks are gone and possibly the column liner is scored. Look at every weld at the arm pivots and the top beam connection.

On a four-post, walk the runways and look for deflection, buckling near the middle, and cracks at the crossmember welds. Check that all four columns and both runways are from the same lift — mixed-and-matched four-posts are more common than you’d think, and mismatched runway lengths mean the cable geometry will never equalize. Cables are your other big-ticket item: look for broken strands, kinks, flat spots, corrosion, and cable ends that are peened or deformed. Cables are wear items and we stock them, but a full set plus labor changes the value of a deal significantly. Any used lift buying guide that skips the cable inspection is doing you a disservice, because that’s where a cheap lift quietly becomes an expensive one.

Hydraulics, Locks, and the Stuff That Fails Quietly

Bring a flashlight and look at the cylinder rods. Pitting, scoring, or a rust line where the rod sits at rest all point to seal failure soon. Wet columns, an oily base plate, or a power unit sitting in a puddle of ATF are the seller’s answer to a question you should have asked. Cylinders are rebuildable and replaceable — we handle both — but on some obsolete models the cylinder is the reason the lift gets scrapped, because a custom-built replacement costs real money.

Then test the locks. Every lock, every position, both sides. On a two-post you should hear each latch engage as the carriage passes each notch, and you should be able to set the lift down onto locks at multiple heights and hear it seat solidly. Weak, sticky, or silent locks usually mean broken springs, stretched cables, or corroded latch pivots. Those are fixable, but a lift with dead locks has been operated unsafely for a while, which tells you something about the rest of it. Also check the power unit: motor start under load, pump noise, reservoir fluid color, and whether the down valve holds. A lift that drifts down on its own is a lift with a bad valve or a leaking cylinder, not a bargain.

The Costs Nobody Puts in the Ad

The purchase price is rarely the real number. Teardown and removal takes time and equipment — columns are heavy, four-post runways are awkward, and pulling anchor bolts out of forty-year-old concrete is its own project. Then there’s trucking, and in Iowa that can mean a couple hours each way. Then reinstallation: new anchors, shims, leveling, torque to spec, and a full function test.

Add likely parts. Assume you’ll want new cables, new slide blocks, fresh hydraulic fluid, and possibly a hose set on anything more than fifteen years old. Assume arm restraint gears and lock springs. None of those are catastrophic individually, but together they can add up to a meaningful percentage of what a new entry-level lift costs. We’re not saying that to talk you out of it — we install used lifts for customers all the time and they work great. We’re saying it so the comparison is honest. Our used lift buying checklist puts these line items in a form you can carry to the inspection, and it pairs well with this used lift buying guide when you’re evaluating two or three candidates at once.

Concrete, Ceiling, and the Space You Actually Have

We’ve watched more used lift deals die on the concrete slab than on the lift itself. A two-post needs adequate thickness and strength under every anchor — typically four inches minimum of good, cured concrete, more for higher capacities, and no cracks or control joints running through the anchor pattern. Garage slabs poured for parking are frequently thinner than advertised, and a sawcut core sample is cheaper than a failed anchor. If the slab isn’t right, you’re either cutting and pouring pads or buying a different style of lift.

Ceiling height sets your options too. A clearfloor two-post needs meaningful overhead room for the top beam plus the vehicle. Baseplate models trade floor obstruction for lower height. Four-posts and mid-rise scissors work in shorter buildings and often make more sense for home garages and storage. If the used lift you found is a full-rise two-post and your ceiling is nine feet, the deal is already over regardless of condition — and that’s worth knowing before you rent a trailer. For lower-clearance situations, our used scissor lift buying guide covers what to look for in that category specifically.

When to Walk Away — and How We Can Help

Walk away from a missing serial tag. Walk away from an orphan brand with no parts path. Walk away from cracked welds, bowed columns, buckled runways, or concrete that’s failed around the anchors. Walk away from a seller who won’t let you cycle the lift under load, or who has no manual and no history. And walk away from anything that was clearly overloaded — bent arms and mushroomed pads are honest evidence of how the lift was treated for years.

What we do for people is simple. Send us the photos and the serial tag before you buy. We’ll tell you what the lift is, what it’s worth doing, what parts are available, and whether we’d put our own name on the installation. We can quote removal, trucking within Iowa and the surrounding region, reinstallation, anchoring, and a post-install safety inspection. We stock cables, cylinders, slide blocks, locks, arm restraints, and power units for the major brands, so a used lift with a good frame becomes a reliable lift quickly. Use this used lift buying guide as your first filter, then call us at 800-674-9302 before the money moves. A ten-minute phone call has saved a lot of Iowa shops from a very expensive piece of scrap.
