Before you hand over cash for somebody’s old hoist, run through a used two post lift inspection checklist so you know exactly what you’re buying instead of hoping for the best. We’ve walked into more Iowa garages than we can count where a farmer, a side-hustle mechanic, or a small shop owner bought a lift off Facebook Marketplace only to find out the anchor bolts were stripped, the cables were frayed, or the unit was missing a critical safety part entirely. As an Iowa-based lift installer and parts supplier, we’ve seen the good deals and the disasters, and this checklist is built from what actually goes wrong when a two post lift changes hands.

Why a Used Two Post Lift Inspection Checklist Matters More Than Price
A used two post lift inspection checklist matters because the sticker price is almost never the real cost. We’ve quoted replacement cables, arm restrictors, and hydraulic hoses for lifts that were sold as “ready to go” and ended up needing several hundred to a couple thousand dollars in parts and labor before they were safe to run. That math changes the deal fast, and it’s the reason we tell every caller to walk the lift with a checklist in hand before any money changes hands, not after.
The other reason a used two post lift inspection checklist matters is liability. If you install a lift with a cracked weld or a worn safety latch and it drops a vehicle, that’s not a warranty claim anymore — that’s an injury or a totaled car. Most used lifts on the secondhand market were pulled out of a shop that upgraded or closed, and nobody can tell you how well it was maintained. Treat every used unit as unknown history until you’ve verified it yourself, component by component, the same way we do when we’re asked to inspect one before a sale.
Start With the Columns and Base Plates
Stand at the base of each column and look for rust bubbling through the paint, especially near the floor where moisture collects. Surface rust is normal on an older lift; flaking rust or pitted metal that flakes off when you scratch it is not. Check that both columns are still plumb and haven’t been bent from a vehicle strike — a column that’s out of square will bind the carriage and wear the rollers unevenly over time, which is expensive to fix later.
Next, look at how the lift was anchored in its last location. Anchor bolts left behind or sheared off tell you the lift was removed in a hurry, and that’s not necessarily a red flag on the lift itself, but it does mean you’ll need new anchors and a fresh concrete inspection at your install site regardless of what the base plates look like. We always tell buyers that a two post lift is only as good as the floor it sits on, and that’s a separate inspection from the lift hardware itself.
Inspect the Cables, Chains, or Hydraulic Lines
Cables are the single most common failure point on a used two post lift, and they’re also the cheapest thing to be wrong about if you catch it early. Look for fraying, kinks, flat spots, or rust discoloration along the entire length of each cable, not just the visible sections. If the seller can’t tell you when the cables were last replaced, budget for new ones regardless of how they look — cable age is invisible from a distance and cheap insurance compared to a dropped vehicle.
If the lift runs on hydraulic cylinders instead of or alongside cables, check for weeping fluid at the seals, pitting on the cylinder rod, and slow or uneven lift speed on each side. A cylinder that leans or drifts down over a few minutes usually needs a reseal or replacement, which we stock for most major brands. Our two-post lift cable inspection checklist goes deeper into exactly what healthy versus failing cable looks like if you want the long version.
Check the Safety Locks and Arm Restraints
Every two post lift should have a working mechanical safety lock system that engages automatically as the carriage rises and holds it in place if the hydraulic or cable system fails. Run the lift up and down a few times and listen for the locks clicking into place — if they’re silent, sticky, or someone has clearly disabled them with a zip tie or wire, that’s a dealbreaker until it’s fixed. This is the single most overlooked item in a rushed used two post lift inspection checklist walk-through, and it’s the one that actually saves lives.
Also check the arm restraint pins or latches that keep the swing arms from sliding out from under a vehicle mid-lift. These wear out from constant use and get lost during a move, and a lift missing them is not safe to operate no matter how solid everything else looks. Our two-post lift safety inspection checklist covers this in more detail for anyone putting a written protocol together for a shop.
Test the Hydraulic Power Unit and Controls
Run the lift through a full cycle with no vehicle on it and watch the power unit for noise, leaking fluid, or a motor that struggles to start. A healthy pump should sound consistent and shouldn’t need to be tapped or jump-started to engage. Check the fluid level and color in the reservoir too — dark, milky, or metallic-smelling fluid usually means internal wear that’s about to become a bigger repair.
Test the descent controls specifically, since that’s where age shows first. The lift should lower smoothly and stop cleanly when you release the lever, not drift, jerk, or free-fall even slightly. If the seller has records of the power unit being serviced, that’s a good sign, but don’t take their word for it without watching it run yourself through at least two or three full cycles.
Verify the Load Rating Matches What You Actually Need
Two post lifts come rated anywhere from around 9,000 lbs up through 15,000+ lbs, and the used market is full of lighter-duty units being resold to buyers who actually need to lift trucks or vans. Find the capacity plate on the lift and confirm it’s legible and matches what the seller told you, because plates get swapped or painted over more often than people expect. Buying under capacity for your heaviest vehicle is one of the fastest ways to overload and damage a used lift within the first year.
If there’s no visible capacity plate at all, that’s worth pausing on. We can often identify a lift by frame shape, arm style, and column spacing even without a plate, but it takes a photo and a phone call, and it’s worth doing before you commit rather than guessing at what it can safely hold.
Get the Full Picture With a Documented Annual-Style Inspection
The smartest move before buying any used two post lift is to run the same process a shop would use for a routine annual inspection, checking every wear item in one pass instead of eyeballing the obvious stuff. That means columns, cables or cylinders, safety locks, arm restraints, power unit, and capacity plate, all in one sitting, with notes on what needs replacing before it goes into service. Our two-post lift annual inspection checklist is the same framework shops use every year and works just as well as a one-time pre-purchase inspection.
If you’re buying locally in Iowa and want a second set of eyes before you close the deal, we do pre-purchase inspections and can usually tell you within an hour on-site whether a used lift is worth what’s being asked. It’s a small cost compared to discovering the problems after it’s bolted to your floor and a vehicle is already sitting on it.
