The Cedar Rapids family-owned garage we quoted this spring was on its third generation of ownership, and the grandfather, the father, and the son were all in the shop the day we walked it. They needed a car lift for seasonal vehicle storage — winter tires off, summer project cars stored up top, the classic setup — and they wanted to compare real model numbers with real dimensions before signing anything. We spent about two hours pulling up install manuals on a laptop while they took notes. This article is the version of that meeting distilled to the specs and the honest trade-offs that mattered most for their bay.
Four-post lifts sized for seasonal storage in family garages, with real specs and Iowa install support from our team.
Why a four-post car lift is the storage answer
Seasonal storage is a four-post story, not a two-post story. A four-post car lift holds the vehicle on runways under the tires with the parking brake set, so you can leave a project car up in the air for six months without cables carrying dynamic load. Two-posts hold the vehicle by the frame through hydraulic cylinders, and while modern hold-valve systems are excellent, no shop we know leaves a vehicle up on a two-post for a season. That is a fundamental storage lift versus service lift distinction.
The Cedar Rapids family had a working two-post already for daily service work, so this lift was purely for the storage bay. That simplified the conversation. We were not trying to make one lift do two jobs. We were sizing a four-post to hold a specific set of vehicles — a classic muscle car, a mid-2000s SUV, and an older pickup project — with room for one working car underneath during winter months. That gave us a clear duty cycle and a clear load requirement, and it let us compare two real models against those numbers instead of against a brochure.
The Rotary SPO10 real dimensions
The Rotary SPO10 four-post — a general home-storage model in the Rotary family — has an overall length of about 194 inches, an overall width of about 108 inches, and a lifting capacity of 9,000 pounds. Runway width is 20 inches nominal, runway length is about 174 inches usable, and the wheelbase range accommodates most passenger vehicles from a sports car up through a full-size pickup. Rise height is about 66 inches from the floor to the top of the runway at full extension, which is enough for a person to walk under most vehicles for storage access.
Column height at full retraction is about 90 inches, so the storage lift fits under a 10-foot ceiling with a passenger car stored on top if the stored car has a roof height under about 55 inches — think a sedan or coupe, not an SUV. For an SUV or a truck stored up top, you need an 11 to 12 foot ceiling, which the Cedar Rapids garage did have. Locking mechanism is mechanical steel latches at multiple positions with a hydraulic power-down system, and the runways include drip trays. Those are real specs from the install manual, not sales sheet approximations.
The BendPak HD-9 real dimensions
The BendPak HD-9, a general home-storage four-post in the BendPak line, has an overall length of about 197 inches, an overall width of about 108 inches, and a 9,000-pound capacity. Runway width is 20 inches, and rise height is comparable to the Rotary. The dimensional similarity is not a coincidence — the home storage four-post class has converged on a fairly consistent footprint over the last decade because most residential garages and family shops have similar geometry constraints across the country.
Where the HD-9 differs is in the accessory ecosystem. BendPak offers a wider off-the-shelf catalog of drip trays, jack platforms, casters, and drive-over ramps than any single Rotary storage lift comes with. That accessory catalog is a real value if you know you want the extra stuff. If you do not need it, you are paying for a broader parts pipeline you will never touch. Locking positions are similar in count to the Rotary. Cable equalization is standard on both. Power-down speed and hydraulic pump specs are within a couple percent of each other. On paper, these two lifts do the same job. The differences show up in resale value, dealer support in Iowa, and warranty transferability.
Runway width, casters, and load distribution
Runway width matters for stored vehicles because narrower runways make it hard to walk around the vehicle once it is up. Twenty inches is standard on both the SPO10 and the HD-9. A wide-runway variant of the SPO10 runs 24 inches, and BendPak offers an XLT-width variant on some models. For a family garage storing a mix of vehicles, 20-inch runways handle sports cars easily but require careful drive-on for wider-tire trucks. We measured the Cedar Rapids trucks and confirmed they fit inside 20-inch runways without hanging over the edges.
Casters are a small feature with a large practical impact. Both the SPO10 and the HD-9 offer optional caster kits that let you roll the lift across the garage floor when it is not loaded. For a family shop that occasionally needs to move the lift out of the way for a big project, casters are a real convenience. Load distribution is where four-posts win the storage game — the vehicle weight sits on the runways spread across four columns and eight anchor points, so slab stress per anchor is much lower than a two-post that concentrates load at two columns. That is why four-posts can sit on lighter slabs than two-posts of the same nominal capacity.
Locking mechanism differences that matter
Both the SPO10 and HD-9 use mechanical steel locks that drop into notches at multiple heights. The Rotary lock arm design is one-piece cast steel with a spring-loaded engagement. The BendPak lock is a similar design with slight differences in the pull-cable release routing. Neither is objectively better. Both meet ALI (Automotive Lift Institute) certification standards, which is the certification we insist on for any car lift we install because it is the U.S. standard for structural safety and lock reliability. If a lift is not ALI-certified, we will not sell it.
Where locking mechanisms matter for storage is in how quiet they are and how easy they are to disengage. Both brands have a small learning curve on the release cables, and both settle into second nature after a few uses. What matters more for a family shop is the maintenance interval. Rotary specifies annual inspection of lock pins and springs. BendPak specifies similar intervals with slightly different lubrication recommendations. We walked the Cedar Rapids family through both maintenance schedules and told them honestly that either lift, properly maintained, will last two to three decades in a family garage environment.
Load capacity versus stored vehicle weight math
Capacity math for storage is where most home buyers get overconfident. A 9,000-pound-rated lift is not a lift that should hold 9,000 pounds long-term. Manufacturer rated capacity is a peak dynamic rating for lifting, not a static long-term storage rating. For seasonal storage, we tell customers to stay comfortably under 60 percent of rated capacity for stored vehicles that sit up for months at a time. That means a 9,000-pound lift is a comfortable storage platform for vehicles up to about 5,500 pounds.
The Cedar Rapids family’s stored fleet was mostly inside that number. The muscle car is around 3,300 pounds. The mid-2000s SUV is closer to 5,800, which we flagged as right at our recommended ceiling — we told them if they wanted to store the SUV long-term they should keep it on top only in winter months and rotate it out in summer. The pickup project is around 6,500, which we told them honestly was too heavy for a 9K storage lift for long-term parking and recommended they store it on the ground. That was not what they wanted to hear, but it was the honest answer, and we would rather deliver an honest number now than pull a bent lift out of their garage in 10 years.
Which car lift we recommended for the Cedar Rapids family
After walking the specs, we recommended the Rotary SPO10 with the wide-runway variant, casters, drip trays, and a jack platform. Cost was in the mid range of four-post storage lifts, install was one afternoon with our crew, and the Rotary parts pipeline in Iowa is strong enough that they will have replacement cables, pulleys, and lock hardware available for as long as they own the lift. The BendPak HD-9 would have been a valid alternative and we said so. Neither would have been a mistake. The Rotary won on parts availability and Iowa dealer proximity, not on raw specs.
If you are running a family garage in Cedar Rapids and staring at a similar car lift decision, the process is what matters more than the brand. Measure your ceiling, weigh your vehicles, plan for the long-term storage load, and pick the lift that matches the specific work you will do.
