Choosing a 2 post car lift is easy compared to figuring out where to put it. We spent a morning last winter in an Ankeny shop with a fleet manager who ran nine service vans and a handful of light-duty pickups, and the entire conversation was about eighteen inches. That was the difference between a layout where his techs could roll a hub press cart between the columns and one where they had to back it out every time. The lift itself was almost an afterthought. We are Auto Lift Services out of Ames, and we have installed in enough Des Moines metro buildings — old brick shops off Second Avenue, new steel buildings in Grimes and Waukee — to know that bay geometry decides whether a shop feels fast or cramped for the next fifteen years.

The Fleet Shop Problem: Wheel Bearings All Day
Small-fleet operators in the Des Moines metro run a very specific repair profile. High-mileage vans and pickups doing delivery, service calls, and route work rack up brake jobs, tires, and — because of Iowa winters and the salt that comes with them — a steady stream of wheel bearing and hub assembly replacements. That job dictates the bay more than anything else. A hub swap means the wheel comes off, the caliper and rotor come off, and then somebody is either swinging a hammer, running an impact at an awkward angle, or wheeling a press cart into position. All of that happens between and around the columns.
The tech’s body position matters too. On a pressed-in bearing, a tech spends real time standing sideways in the space between the front column and the vehicle’s front wheel. If that gap is tight, they work with their elbows pinned and the job takes longer every single time. Over a year of fleet work, that lost time is worth more than the price difference between two lift models. This is why we push fleet shops to plan around the widest job they do rather than the average one. The average job fits anywhere. The worst job — a dually rear hub with a press cart and a torch cart both in play — is the one that defines whether the bay works. Get that one right and everything else is comfortable.
Configuration A: Clear-Floor Overhead in a Tall Bay
The first layout we spec whenever ceiling height allows is a clear-floor overhead two-post. The floor between the columns is completely open — no crossbar, no hose channel, nothing to roll a cart over or trip on. For wheel bearing work this is genuinely better. A hub press cart, a transmission jack, an oil drain, a parts bin — all of it rolls straight through without lifting a wheel over anything. Techs stop thinking about the floor entirely, which is the whole point.
The cost of that is height. An overhead unit needs enough clearance for the top beam plus the vehicle at full lift, and the shutoff bar sits above that. Most manufacturers want somewhere in the twelve-foot range as a practical minimum for a standard 10,000 or 12,000 lb model, and taller if you want to put a tall van at full height. A lot of newer metro buildings in Ankeny, Grimes and Altoona have fourteen to sixteen foot ceilings and this is a non-issue. Older shops in the older parts of Des Moines frequently do not. We have measured plenty of bays at eleven feet or a hair under, and that immediately changes the conversation. If your ceiling is tall and clear of ductwork, sprinkler heads and unit heaters, a clear-floor 2 post car lift is the layout we recommend nearly every time.
Configuration B: Baseplate in a Low or Obstructed Bay
The second configuration is a baseplate model, where the hydraulic and cable routing runs through a low crossover plate on the floor instead of an overhead beam. This buys you the vertical space back. In a bay with an eleven-foot ceiling, or one where a heater hangs exactly where the top beam would go, a baseplate unit is often the only way to get a two-post in at all. We have installed these in Des Moines metro shops where the alternative was no lift.
The trade-off is exactly what you would expect. There is now something on the floor. Modern baseplates are low and ramped, and a tech gets used to them in a week, but a cart with small casters will still catch, and a floor jack has to be lifted over. For a fleet shop doing constant wheel bearing service with rolling equipment, that is a daily friction cost. It is not a dealbreaker — plenty of very productive shops run baseplate units — but it is a real difference that should be weighed honestly rather than discovered after install. We also find baseplate models slightly easier to service on the hydraulic side, since everything is at waist height rather than overhead. If your building forces the decision, take the baseplate and do not feel bad about it. If your building does not force it, go overhead.
Drive-Through Width, Column Spacing, and Van Doors
Here is where fleet shops get bitten. Service vans are wide, and many of them have doors that open ninety degrees or more into the space beside the vehicle. If you set your columns at the minimum spec spacing, your tech can lift the van but cannot fully open the driver’s door once it is up. That sounds trivial until somebody needs to grab a scan tool off the seat six times during a diagnosis. Similarly, some models offer an expandable top beam that lets you configure wide or narrow drive-through — that option is worth having in a fleet bay even if you set it narrow at first.
Column spacing also interacts with asymmetric versus symmetric design. An asymmetric setup rotates the columns and moves the vehicle rearward so doors clear the posts, which is exactly what a shop full of vans wants. A symmetric setup centers the vehicle and generally handles longer, heavier vehicles more evenly, which matters if pickups dominate your fleet. Most metro fleet shops we work with land on asymmetric or a versymmetric design that splits the difference. When we lay out a 2 post car lift for a mixed fleet, we start by asking which vehicle in the fleet gets worked on most often, then set the geometry around that one and verify the others still fit.

Concrete, Anchors, and What Iowa Slabs Actually Look Like
Every layout conversation eventually hits the floor. Manufacturers publish minimum slab thickness and PSI requirements, and they are not suggestions — the anchor pull-out strength is the entire thing holding a loaded column upright. We routinely core-check slabs in metro shops and find four inches where the owner believed there were six, or six inches of good concrete over a soft base that was never compacted properly. Older buildings around Des Moines were frequently poured for storage or light manufacturing, not for point loads from a lift column.
If the slab does not meet spec, the fix is a cut-and-pour: saw out a pad under each column, dig, and pour a footing to depth. It adds cost and a few days, but it is the difference between a lift you trust for twenty years and one that develops a lean. We have had owners ask if they can just use longer anchors. They cannot — an anchor is only as good as the concrete around it, and length does not fix thickness. This applies to every 2 post car lift regardless of brand or price point. Before you commit to a layout, get the slab verified. It is the cheapest step in the process and the one that determines whether the rest of it works. Also worth reading: two-post lift concrete requirements.
Comparing the Two Layouts Side by Side for a Fleet Bay
Put the two configurations next to each other for a nine-van fleet operation and the picture gets clear. The clear-floor overhead wins on daily workflow: open floor, unobstructed cart movement, faster hub jobs, cleaner bay. It loses on ceiling requirement and on the fact that a tall van at full lift can put its roof uncomfortably close to the top beam and shutoff bar. The baseplate wins on vertical clearance and on hydraulic serviceability. It loses a small amount of workflow speed every day and adds a trip hazard that has to be managed with paint and habit.
Our recommendation for most Des Moines metro fleet shops with adequate ceilings is a 12,000 lb clear-floor asymmetric unit with an expandable top beam. That capacity handles loaded three-quarter-ton pickups and heavy vans without living at the top of its rating, and the arm geometry gives techs room around the wheels. For a shop where the heaviest vehicle is genuinely under six thousand pounds and money is tight, a well-built 10,000 lb model is entirely adequate and we will say so. What we will not do is put a 2 post car lift into a bay where it does not fit and let you discover the problem on install day. Send us a sketch with ceiling height, door height, bay width, obstructions, and your heaviest vehicle, and we will mark up the layout before anything ships.
