Garage Two Post Lift Pre-Purchase Checklist for Farm Shops

A garage two post lift is the biggest single equipment purchase a farm shop typically makes in a decade, and rural buyers around Waukee call us with the same three or four unanswered questions every time: is my power right, is my slab thick enough, will the ceiling clear a raised pickup, and which brand of lift can actually align a farm truck. This piece is the pre-purchase checklist we walk every farm shop through before we quote a lift, the same checklist that catches the surprises that turn a two-week install into a two-month project. Go through it before you call and the site visit gets a lot shorter, and the quote hits the number that actually sticks.

The Electrical Circuit and Phase Question First

Most Waukee farm shops have single-phase 220V service to the shop building, and a standard 10,000 lb garage two post lift runs happily on single-phase 220V at 20 amps. Some larger commercial lifts require three-phase power, which is common on grain-farm operations that already run three-phase for dryer motors, augers, and grinders. If your shop has three-phase you have more equipment options; if you do not, you are in the single-phase market. Never assume, check the panel. If the shop panel shows red, blue, and yellow leads with a green ground, that is three-phase. Two hot legs and a neutral is single-phase.

If you do not know, take a phone photo of the panel and text it to us before we quote. We have had rural buyers order a three-phase lift and only realize at install that their shop was single-phase, which triggered a $2,000 to $4,000 utility upgrade and sometimes weeks of waiting for the co-op to schedule the transformer swap. The other electrical question is amperage headroom. A 220V lift motor pulls 15 to 20 amps at startup. If your shop is running welders, air compressors, and lift motors off the same panel, a load calculation is worth doing before the install. We can do that calculation as part of the site visit, or your local electrician can. Do not skip it.

Slab Thickness, Age, and Reinforcement

Slab thickness matters more than any other physical variable for a farm-shop garage two post lift. Rotary and Challenger both require 4.25 inches minimum on 10,000 lb symmetric lifts, and 6 inches for 15,000 to 18,000 lb heavier configurations. Most Waukee-area farm shops built in the last 20 years pour 4 to 6 inches of reinforced concrete, so this is usually not a problem, but slabs older than 40 years often ran 3 to 3.5 inches with minimal rebar. Check the original build documentation if you have it. If you do not, we hammer-drill a small test hole during the site visit to measure.

Slab age also matters. Fresh concrete (under 30 days) is not fully cured and will not hold anchor bolts at spec. If you are building a new shop for the lift, we recommend pouring 6 inches of 4000 psi concrete with #4 rebar on 12-inch centers in the column footprints, minimum. That is overkill for a 10K lift but underkill costs way more later. If the slab is thin we can pour column footprint pads (5 by 5 feet, tied to the existing slab with rebar dowels) at each column location. That fix runs $600 to $1,200 in concrete work and is what makes older buildings viable for a proper lift install. Every farm shop we quote gets the slab tested before we finalize the number.

Ceiling Height for Raised Trucks and Farm Vehicles

Ceiling clearance is the third check. A garage two post lift with an overhead cable configuration needs 12 to 13 feet of clear height from finished floor to the lowest overhead obstruction, including light fixtures, ductwork, and sprinkler runs. For a farm shop that services raised pickups, add another foot of clearance to accommodate the raised vehicle at maximum lift height. That means 13 to 14 feet total. Most modern pole barns run 14 to 16 feet at the peak but only 10 to 12 at the sidewalls, so lift placement matters. Center of the building is usually the workable spot.

Older farm shops built in the 1970s and 1980s often have 10 to 11 foot ceilings, which pushes you toward a baseplate configuration. Baseplate lifts run the equalizer through a floor-level bar instead of overhead and reduce required clearance to about 10.5 feet. The tradeoff is the floor bar, which is a step-over hazard until the crew learns to expect it. For a farm shop that runs mostly farm trucks and pickups with occasional tractor front-end work, baseplate is fine. For a shop that runs a mix and wants clean floor access for tire changing and other rolling equipment, overhead cable is worth the ceiling investment if possible. Measure to the lowest obstruction, not the peak.

The Alignment-Capable Configuration Question

Alignment work is not something every farm shop plans for at purchase time, but if there is any chance you will add alignment capability later, spec the garage two post lift for it now. That means a symmetric column configuration (not asymmetric), 10,000 lb minimum capacity, three-stage telescoping arms, and either overhead cable or a baseplate model with a rated flat-floor compatibility. Do not buy an asymmetric lift and try to add alignment later. The column offset makes alignment work harder even on a good rack.

Both Rotary and Challenger sell symmetric 10K lifts that are alignment-ready. For a rural farm shop that might align farm trucks, road pickups, and the occasional hobbyist car, a symmetric lift is the right base regardless of whether alignment gets added year one or year five. If you know alignment is coming, add a Hunter-compatible turntable set and a rack-mount kit at purchase to save on a second install. Hunter is the only alignment equipment brand we recommend, and their aftermarket rack kits work on both Rotary and Challenger symmetric lifts. For any farm shop trying to build alignment capability from scratch we can quote the lift plus turntables plus alignment computer as a package. Call 800-674-9302 and we will walk through the timing that fits your build-out plan.

The Waukee-Specific Building and Permit Landscape

Waukee-area farm shops are usually outside city limits, which means county building codes rather than city codes apply, and the permit landscape is lighter than for a shop inside Ankeny or Des Moines. Dallas County typically requires a mechanical permit for commercial equipment installation and an electrical permit for the circuit run. Residential-use farm shops (not businesses) sometimes fall under simpler agricultural-building rules, so check with the county assessor’s office before you assume. Insurance is a separate matter.

Your commercial or farm insurance policy will want the lift documented on the schedule of equipment, and any claim involving the lift will require proof of ALI Gold certification and annual inspection. That is true whether the county permits it or not. We handle permit paperwork for shops inside city limits and file directly with the county for rural sites. If your farm shop is in a township without formal permitting, we still recommend a private engineering inspection at install completion. It is not required by anyone but gives you documentation if a claim ever gets filed. Rotary and Challenger both accept the private inspection as part of their warranty documentation trail. It is a $200 to $400 line item and it is usually the last piece of paperwork any lift file needs. Do not skip it.

Freight and Delivery Access on a Rural Site

Delivery access on a rural Waukee site can add or subtract $200 to $500 from the total project cost. Freight companies charge extra for residential-designated addresses, extra for lift-gate service, and extra for narrow driveway or difficult unload. If your farm shop has forklift access and a tractor or skidsteer that can move a palletized garage two post lift, delivery is straightforward and priced at the low end. If the freight truck has to unload with its own lift-gate onto a gravel driveway, expect the higher end.

We coordinate freight through the manufacturer’s preferred carrier network, which usually gets us 10 to 20 percent off retail freight pricing. We will also schedule delivery to arrive the day before install so there is no waiting on the crew. Palletized lift components weigh about 1,800 to 2,200 lbs for a 10K commercial lift. A standard forklift with 5,000 lb capacity handles it. A tractor loader with 3-point pallet forks does too. What does not work is trying to slide the pallet off with a floor jack. The boxes shift and components get damaged. Uncrating with proper equipment matters. If your farm shop does not have a forklift we can rent one for install day and add it to the quote. It is cheaper than a damaged lift.

The Complete Pre-Purchase Checklist Summary

Here is the complete pre-purchase checklist for a Waukee-area farm shop planning a garage two post lift install. One, panel type and amperage: single-phase or three-phase, and enough headroom for a 20-amp motor circuit. Two, slab thickness and age: 4.25 inches minimum reinforced, cured at least 30 days. Three, ceiling clearance: 12 feet for standard overhead, 10.5 for baseplate, plus raised-vehicle allowance. Four, column footprint and door access: 12-foot minimum between columns, clear approach from the shop door. Five, alignment plan: symmetric now if alignment is anywhere in the future.

Six, delivery: forklift or equivalent, or add a rental line to the quote. Seven, permit path: county mechanical and electrical, or private inspection if no formal permit is required. Eight, insurance schedule: lift listed on your policy with ALI Gold certification documented. Nine, maintenance plan: annual ALI inspection, quarterly self-check, fluid and cable service intervals. Ten, warranty registration: filed with the manufacturer at install. Walk through this list before you call for a quote, and the quote will be tighter, the install will run cleaner, and you will not get surprised at commissioning. For any farm shop weighing a lift purchase and wanting a site visit, call 800-674-9302 and we will set it up. The site visit is what makes the checklist real.
