Used Automotive Lifts: What to Inspect Before You Buy

Every month someone calls us after finding a lift on Facebook Marketplace or at an auction, asking us to come take a look before they hand over cash. That’s the right instinct, because used automotive lifts what to inspect is not a question you want to answer after the money’s already gone. A lift that looks fine sitting still in a stranger’s garage can hide cracked welds, worn cables, or a control valve that’s one bad day from failing. We’ve been installing and servicing lifts across Iowa for years, and we’d rather walk you through the checklist now than get a panicked call after something drops.

Start With the Frame and Welds

The single most important item on the used automotive lifts what to inspect list is structural integrity, and that starts with the columns, arms, and base plates. Get down low with a flashlight and look at every weld seam for cracking, especially where arms pivot and where the columns meet the base. Surface rust is cosmetic and usually fine; pitted or flaking rust that’s eaten into the steel is not. If the lift has been outside or in a shop with a leaky roof, check the bottom few inches of each column closely, because that’s where moisture pools and corrosion does the most damage over time.

Also look for any signs of previous damage that’s been patched rather than properly repaired. A bent arm that’s been straightened, a column with a dent that’s been ground smooth, or mismatched paint over a weld are all red flags. We’ve turned away lifts for resale because the frame had been welded in a spot the manufacturer never intended, which usually means someone already had a failure and did a shade-tree fix instead of a real repair. If you can’t get underneath it comfortably to inspect, that’s reason enough to bring in someone who can before you buy.

Cables, Chains, and Pulleys on Two-Post Units

On a two-post lift, the cables carry the entire load and equalize it between both columns, so they deserve close attention on any used automotive lifts what to inspect walkthrough. Look for frayed strands, kinks, flat spots, or rust along the cable length, and check that the equalizer cable is still tensioned evenly on both sides. If one side sags noticeably more than the other, the cable has stretched or the equalizer needs adjustment, and that’s a job for a technician before the lift ever goes into service.

Pulleys and sheaves should spin freely without wobble or grinding, and the grooves shouldn’t be worn into a sharp V shape from years of cable friction. Chain-drive lifts need the same scrutiny on the chain itself, checking for stretch, rust, and proper lubrication. None of these parts are exotic or expensive to replace, but they’re also not something you want to discover is bad after the lift is loaded with a customer’s truck. We carry OEM and compatible cables for most brands, so replacing a tired set doesn’t have to mean replacing the whole lift.

Hydraulic Cylinders and Fluid Condition

Whether it’s a two-post, four-post, or in-ground lift, the hydraulic cylinder is doing the heavy lifting, and leaks are one of the most common issues we find on used equipment. Check around the cylinder rod and seals for weeping fluid, and look at the fluid itself if you can access the reservoir — it should be relatively clean, not milky or full of metal particles. A slow leak might just need new seals, but a cylinder that’s scored on the inside of the bore usually needs to be rebuilt or replaced entirely.

Run the lift through a full cycle if the seller allows it, watching for smooth, even movement without jerking, shuddering, or unusual noise from the pump. A lift that drifts down on its own after being raised and left to sit has a hydraulic problem, even if it seems minor at the time. This is one of the areas where a pre-purchase inspection pays for itself, because cylinder work isn’t the cheapest repair, and knowing about it before you buy gives you room to negotiate the price down or walk away.

Locking Mechanisms and Safety Systems

The locks that hold a lift at height when the hydraulics are released are arguably the most important safety component on the entire machine, which is why they belong near the top of any used automotive lifts what to inspect checklist. On most two-post and four-post lifts, this means a mechanical latch system that engages automatically as the lift rises. Test that the locks engage cleanly at multiple heights and that the release handle or cable works smoothly without binding.

Worn or bent locking pawls, a release cable that’s stretched out of adjustment, or locks that skip a notch instead of catching solidly are all serious problems, not minor ones. We’ve seen lifts where someone bypassed the locking system entirely because it stopped working right and they didn’t want to deal with it — that’s a lift we won’t sign off on until it’s fixed. If you’re buying used, ask directly whether the safety locks have ever been serviced or bypassed, and don’t take a vague answer at face value.

Electrical Components and Control Box

The control box, motor, and wiring don’t get as much attention as the mechanical parts, but they matter just as much for reliability. Open the control box and look for corrosion, chewed wiring from rodents, or evidence of water intrusion, which is common on lifts that sat in an unheated building for years. The motor should run smoothly without excessive noise, and the contactor should engage cleanly without buzzing or hesitation.

If the lift has been sitting unused for an extended period, budget for the possibility that seals, gaskets, and electrical connections have dried out or corroded even if everything looks okay on a quick test. It’s common for a lift that ran fine when it was decommissioned to need some electrical attention after months or years in storage. This is a smaller line item than structural or hydraulic repairs, but it’s still worth factoring into your total cost when you’re comparing a used purchase against a new one.

Age, Manufacturer, and Parts Availability

A lift’s age and brand matter almost as much as its physical condition, because a perfectly sound lift from a manufacturer that’s gone out of business or discontinued a model line can become a parts nightmare down the road. Before buying, find the data plate and note the manufacturer, model number, and capacity rating, then check whether parts are still being made for that model. We work with Rotary, Challenger, BendPak, and Atlas equipment regularly, and availability on those platforms is generally solid, but older or obscure brands can leave you stuck waiting on a part that no longer exists.

This is also where it helps to compare buying used against buying new, since the math doesn’t always favor the cheaper upfront price once you factor in repairs, certification, and installation. We’ve written more on that comparison in our guide to in-ground lifts automotive used vs new and our broader look at automotive shop lifts used vs new, both worth a read before you commit to a used unit.

Get a Load Test and Certification Before You Rely On It

Even after a thorough visual inspection, the only way to really know a used lift is safe is to load test it and have it certified by a qualified technician. This means running it through its full range of motion under actual weight, checking that it holds at height without drift, and verifying that every safety system performs the way it’s supposed to under load, not just when it’s empty. Certification also gives you documentation, which matters for insurance and for any shop that gets inspected by OSHA or a state agency.

If you’re located anywhere in Iowa and searching for someone to handle this, we’ve put together a resource on automotive lifts near me used vs new that covers what to expect from a local inspection and how pricing typically works. Don’t skip this step just because the seller says it worked fine right before you bought it — a proper load test is the difference between hoping a lift is safe and knowing it.
