A dealership service manager out near Marion called us last winter trying to decide between a used two-post rig off a classified ad and a new lift for a restoration bay he was building out behind the main shop. He’d seen garage lifts installed both ways at other stores and wanted to know which one actually made sense for his situation – full-frame trucks, occasional body-off restorations, and a crew that needed the platform up and stable for days at a time, not just a quick oil change. That’s a real question with real dimensions attached to it, and it’s one we walk through with dealership and restoration customers across Iowa constantly. Here’s the technical breakdown we gave him, including the numbers that actually matter when you’re deciding between used and new.

Why Restoration Work Changes the Math on Garage Lifts Installed
Most oil-change bays run a vehicle up, do the work in twenty minutes, and drop it. Restoration and metal work is different – a frame might sit on the arms for a week while someone cuts, welds, and fits new sheet metal underneath. That changes what you need structurally. Lock engagement has to hold reliably at extended dwell times, not just for a quick cycle. Arm reach matters more too, since you’re often working around a stripped body with no bumpers or fenders to reference off of, so you need full sweep to get pads under factory pinch points on a frame that’s been sitting jacked up on stands for weeks.
We also look at ceiling height and post spacing differently for this use case. A lot of restoration bays we’ve seen have lower clearance than a typical service bay because they were converted from storage space, so overhead clearance on a two-post becomes a real constraint – not just for the lift itself but for anything hanging off a hoist above it. When garage lifts installed for restoration work get sized wrong on height or arm reach, the shop ends up fighting the equipment on every job instead of the vehicle.
Used Lift Dimensions and Condition Checks That Actually Matter
If you’re looking at a used two-post, the numbers to check are lifting capacity stamped on the data tag, column spacing (usually somewhere in the 9 to 12 foot range depending on model), and overall height, which on older commercial units can run 11 to 13 feet including the overhead beam on a symmetric design. We’ve had customers show up with a lift already loaded on a trailer, confident it’s ready to bolt down, only to find the cable sheaves are grooved, the safety locks are gummed up with 20 years of grease, or the equalizer cable stretch is inconsistent side to side.
None of that means walk away – a solid used commercial lift can be a great value if the columns and carriage are straight and the hydraulic cylinder isn’t scored. But it does mean budgeting for cables, a lock overhaul, and a fresh inspection before it goes into service. We check cylinder wall condition, arm pin wear, and base plate flatness on every used lift we’re asked to certify, and we’ve turned away units where the frame had enough twist that no amount of adjustment would get it plumb. For restoration work specifically, we push harder on lock and cable condition than we would for a quick-service bay, because that lift is going to sit loaded far longer per cycle.
New Lift Specs Worth Comparing Side by Side
New commercial two-post units in the Rotary and Challenger lines we install give you documented capacity, current safety lock engagement, and warranty coverage you can’t get on a used unit. For restoration and metal work, we typically point dealership and independent shops toward the higher-capacity asymmetric models – often 10,000 to 15,000 lb rated – because a stripped-down truck frame can still weigh more than you’d guess once you account for any remaining drivetrain or fuel tank still in the vehicle.
Arm reach on newer asymmetric designs tends to be longer than what you’ll find on a 15-year-old symmetric lift, which matters when you’re chasing frame contact points on a vehicle with no body panels to guide you. Overhead height on current models is usually published to the inch, so you’re not guessing whether it clears your ceiling joists or an HVAC run – something that trips up more garage retrofits than people expect. New also means a documented install with paperwork that holds up for insurance and, if it’s a dealership bay, for a corporate safety audit.
Freight, Forklift Access, and Site Readiness Before Install Day
Whether it’s used or new, the logistics questions are the same and they matter just as much as the lift spec sheet. Do you have a forklift on site, or do we need to bring one? Is there a loading dock, or are we hand-trucking columns through a service door? We ask these questions on every quote because a lift that shows up on a truck with no way to unload it turns into a half-day delay, and in a restoration bay schedule that’s already tight around body work, that delay compounds.
We also confirm floor thickness and rebar layout before anchor day, especially in older buildings around Marion and central Iowa where the slab in a back bay might be thinner than the main showroom floor. If there’s in-floor heat, we need it shut off the night before so we can see the heat lines and avoid drilling into a tube. None of this is exotic, but skipping it is exactly how garage lifts installed on a rushed schedule end up with anchor problems six months later.
Anchoring, Slab Thickness, and Post Spacing for Heavy Metal Work
Restoration bays often deal with older concrete, and older concrete plus a heavy two-post lift is a combination we take seriously. Most commercial two-post units want a minimum slab thickness in the 4 to 6 inch range with adequate PSI rating and no expansion joints or old anchor holes too close to the new bolt pattern. We’ve walked into bays where a previous lift’s bolt pattern didn’t match the new unit’s footprint at all, which meant patching old holes and drilling fresh ones – doable, but it needs to be planned for in the timeline, not discovered on install day.
Post spacing also needs to account for the widest vehicle you’ll actually put on the lift, not just what fits the doorway. A shop doing restoration work on trucks and larger sedans needs wider column spacing than a shop that only sees compact cars, and we’ve had customers order a lift sized for the average vehicle in their bay only to find their actual restoration project – a wide-body truck or an old sedan with wider door swing – barely clears the columns. Getting this right before the concrete anchors go in saves a very expensive redo.
Cost Factors: Used Savings vs. New Reliability Over Time
Used lifts save money upfront, sometimes significantly, but the total cost picture includes cable replacement, lock service, and inspection labor that new units don’t need for years. For a shop doing occasional restoration work as a side project, a well-inspected used commercial lift can pencil out fine. For a dealership service department running restoration or heavy metal work as a steady revenue stream, the downtime risk of an aging used lift failing mid-project – with a customer’s frame sitting jacked up – often outweighs the upfront savings.
We also factor in maintenance plans differently depending on age. A newer lift under warranty needs a lighter service plan than a used unit that’s already had one owner and unknown duty cycle. When we quote garage lifts installed for a dealership or restoration shop, we lay out both paths with real numbers on inspection frequency and expected part replacement so the decision isn’t just sticker price versus sticker price – it’s total cost of ownership over the years you plan to run that bay.
What We Walk Through On Every Marion-Area Site Visit
When we get out to a shop near Marion or anywhere else in central Iowa, we’re checking ceiling height, floor slab condition, existing anchor patterns, electrical proximity if it’s an air-over-hydraulic unit, and door clearance for the vehicles that bay will actually see. We measure rather than estimate, because a few inches of miscalculated post spacing or overhead clearance turns a good lift choice into a daily frustration.
We also talk through timeline honestly – lifts on order can take time to arrive depending on the manufacturer’s current lead time, and a used unit sourced locally might be available faster but need more prep work before it’s safe to load. Whichever direction a shop goes, we handle the transport, the anchoring, the electrical hookup coordination, and the final safety check so the lift is actually ready to work the day we finish, not just bolted to the floor and left. That full-service approach is why dealerships and restoration shops across the state keep calling us back for the next bay.
