If you’re staring at a Facebook Marketplace listing or a shop-closing auction and wondering what a used lift inspection what to check actually involves, you’re asking the right question before you hand over cash. We install and service lifts across Iowa every week, and we get called out more often than you’d think to look at a “great deal” that turns out to be a liability on wheels — or worse, a liability bolted to the floor. A used lift can absolutely be a smart purchase, but only if someone who knows what they’re looking at goes through it first. This guide walks through exactly what we check, in the order we check it, so you don’t get stuck with someone else’s problem.
Already own the lift and just need cables, arms, or a safety inspection? We stock parts for every major brand and install across Iowa.
Start With the Paper Trail, Not the Steel
Before you even walk over to look at the columns, ask for documentation. A legitimate used lift inspection what to check process always starts here, because paper problems are cheaper to catch than structural ones. Ask the seller for the make, model, and serial number, then look up whether that model has any open recalls or known issues. If they can’t produce a serial tag, that’s already a red flag — tags get removed when equipment has been in a fire, flood, or a violent failure the owner would rather you not know about.
Next, ask how the lift was used. A two-post that spent ten years in a light-duty passenger car shop is a different animal than one that spent ten years lifting loaded pickups and plow trucks at a municipal garage. Ask for maintenance records, even informal ones. If the seller genuinely doesn’t know the lift’s history, discount your offer accordingly and plan on a full teardown inspection rather than a quick once-over. We’ve seen too many buyers skip this step because the price looked good, only to find out later the lift had been overloaded for years and the frame is fatigued in ways you can’t always see from the outside.
Check the Columns, Arms, and Welds for Damage
Walk the full height of each column and look for anything that isn’t factory: dents, bowing, rust-through, or weld repairs that weren’t done by the manufacturer. Any crack in a structural weld is an automatic pass on that unit — cracked welds do not get ground down and touched up, they get the whole assembly replaced. Pay close attention to the base plates and anchor points, since that’s where years of vibration and overloading show up first.
Check the lift arms for bent sections, stripped pads, or restriction pins that don’t lock solidly into every notch. Arms that were dropped or crashed into a vehicle at some point often get “straightened” informally, and that kind of field repair rarely restores full strength. Rock each arm and listen for looseness in the arm pivot; excessive play there usually means worn bushings that need replacing before the lift ever goes back into service. This is one of the most overlooked steps in any used lift inspection what to check walkthrough, because arms look fine from six feet away and only reveal problems up close.
Test the Cables, Chains, and Locking Mechanism
Cables and chains are consumable parts, not lifetime components, and they’re often the first thing to fail on neglected equipment. Look for fraying, kinks, flat spots, or rust along the entire visible length of every cable, not just the section near the pulley. On chain-style lifts, check for stretched links and uneven wear that suggests the chain has been running misaligned for a long time.
Then test the locking mechanism directly. Raise the lift empty, engage the locks, and try to lower it without releasing them first — it should not budge. If the lock releases under load or doesn’t engage cleanly on every notch, that’s a safety-critical failure, not a cosmetic one. We treat this test as non-negotiable on every used lift inspection what to check visit we do for a customer, because a lift that won’t lock reliably is not a lift, it’s a hazard waiting for the wrong moment. Locks and cables are inexpensive to replace compared to what happens if they fail with a vehicle overhead.
Inspect the Hydraulic System for Leaks and Slow Drift
Run the lift up and down a few times and watch the cylinder, hoses, and fittings closely for any sign of weeping fluid. A little residual oil film is normal on an older unit, but active dripping or a puddle under the power unit tells you seals need attention now, not eventually. Check the hydraulic fluid level and color in the reservoir — dark, gritty fluid suggests it hasn’t been changed in years, which accelerates wear on internal seals and valves.
Load the lift with a vehicle if the seller allows it, raise it to a working height, and watch for drift over several minutes. Any lift that settles noticeably on its own has either a worn cylinder seal or a valve that isn’t holding pressure, and both are repairable but should factor into your offer. This step matters most for two-post and four-post lifts moving heavier vehicles, since a slow drift under a loaded frame is far more dangerous than the same drift under an empty lift.
Check the Power Unit and Electrical Components
Open the power unit housing and look at the motor, wiring, and switches for corrosion, chewed insulation, or amateur wiring repairs. Lifts that lived in unheated, humid shops for years often have motors that run but are on borrowed time, so listen for grinding, humming, or the motor struggling to build pressure. A motor that takes noticeably longer to raise the lift than it should is already telling you something.
Check that safety features work as designed: the up-limit switch, any interlock systems, and emergency stop functions if the lift has them. These get bypassed more often than people admit, especially on older commercial units where a previous owner got tired of nuisance shutoffs and wired around a safety switch instead of fixing the actual fault. Reversing a bypass like that before installation is mandatory, and it’s worth asking the seller directly whether any safety feature has ever been disabled.
Confirm the Lift Matches Your Ceiling Height and Floor
A used lift inspection what to check process isn’t only about the machine — it’s also about whether it fits your building. Measure your ceiling height against the lift’s fully-raised height plus the height of the tallest vehicle you plan to service, and don’t forget garage door headers or overhead ductwork that can eat into clearance you thought you had. We get calls from buyers who bought a great lift at a great price and then discovered it simply doesn’t fit their bay.
Floor thickness and condition matter just as much. Most two-post and four-post lifts need a minimum slab thickness with proper rebar and cure time, and an older shop floor with cracks or unknown composition may need testing or reinforcement before installation. If you’re unsure whether your floor qualifies, our related guides on used lift inspection basics and a full used lift inspection checklist cover floor requirements in more detail, and we’re always available to walk through your specific building over the phone.
Get a Professional Inspection Before You Install
Even after you’ve done your own walkthrough, we strongly recommend a professional inspection before the lift goes into service, especially for anything rated to handle vehicles over a few thousand pounds. A trained technician can spot fatigue cracks, worn bushings, and hydraulic issues that aren’t obvious to an untrained eye, and they can confirm the lift actually meets current safety standards for its class. This is doubly true if you’re buying a lift that’s changed hands more than once, since damage and repair history tend to get lost after the second or third owner.
Our team travels across Iowa doing exactly this kind of pre-purchase inspection, and we’d honestly rather tell you to walk away from a bad unit than sell you parts to fix it later. If you’re shopping for a scissor lift specifically, our guide on used scissor lift inspection covers a few failure points unique to that style. Whatever you’re considering, a proper used lift inspection what to check appointment costs far less than a failed cylinder or a collapsed arm ever will.
