A Cedar Falls shop that services RVs and travel trailers through the summer and stores customer units over the winter called us with a simple question: how do automotive two post lifts hold up when they sit loaded, unloaded, then loaded again through a full Iowa season? That question is the whole reason we’re writing this. We installed a pair of two post lifts for this shop just over a year ago, and their first annual service gave us a real look at how cables, locks, and hydraulics behave when a lift isn’t running five bays deep every day but instead gets asked to hold heavy, awkward loads for weeks at a time. Here’s what that first year taught us, and what it should tell you if you’re running a similar operation.

Why an RV Shop Chose Automotive Two Post Lifts Over a Rack
This shop initially asked about a truck-style four post setup because they figured taller trailers and tow vehicles would need the drive-on convenience. Once we walked their bay and talked through what they actually work on — tow vehicle brakes, suspension, undercarriage inspections before winter storage, hitch and wiring repairs — a pair of two post lifts made more sense. They needed full access underneath, not just a platform to roll onto, and they needed to get in and out of a vehicle’s frame area without an aisle rail in the way.
We sized the lifts to their heaviest tow vehicles rather than the trailers themselves, since the trailers mostly get blocked and stored rather than lifted. That’s a detail a lot of shops miss — buying capacity for the biggest thing that rolls through the door, not the biggest thing you photograph for the website. With two post lifts, arm reach and swing also mattered more than usual, since dual-rear-wheel trucks and extended cab trucks need arms that can actually clear the frame rails without fighting the tires. We walked through three arm configurations before they landed on the one that worked for their mixed fleet.
Install Day: Concrete, Power, and Ceiling Height in Cedar Falls
Before we ever loaded a lift on the truck, we asked the same questions we ask every Iowa shop: is there a pit, what’s your ceiling height, and is the concrete rated for anchor bolts at this depth? This particular bay had older concrete that needed a core sample before we’d commit to anchor depth, and the ceiling height on one side of the building was tighter than the customer remembered — a few inches lower than the lift’s fully-raised carriage height with a raised tow vehicle on the arms. We adjusted the install plan on site rather than surprising them the day of.
On delivery day, we also asked whether they had a forklift or skid loader on site. They didn’t, so we brought our own equipment to get the columns and carriages off the truck and into position. This is a common gap — a lot of shops assume the installer just muscles everything by hand, and for automotive two post lifts weighing well over a thousand pounds per column, that’s not realistic without the right equipment. Plan for that conversation before your install date, not on it.
The First Six Months: Daily Use Versus Seasonal Storage Load
For the first several months, the lifts saw fairly normal daily use — raising and lowering trucks and SUVs for brake work, suspension inspections, and general repairs. That’s the load pattern most two post lifts are designed around: up, work, down, next vehicle. Where things get different is late fall, when this shop starts raising vehicles and leaving them elevated for extended winter storage prep, sometimes for a full day or more while they finish undercoating, wiring checks, and tire swaps before the vehicle goes into long-term storage.
Extended static load isn’t inherently bad for a two post lift, but it changes what you should be watching. Locks that engage and disengage constantly wear differently than locks holding a static load for hours. Cables under sustained tension can reveal fraying or uneven wear that a quick in-and-out cycle wouldn’t show. We flagged this for the shop early: if you’re going to run automotive two post lifts as part of a seasonal storage workflow, your inspection habits need to account for both use patterns, not just the daily one.
What the First Annual Cable Inspection Found
At the one-year mark, we came back for a full service visit, and cables were the first thing we checked. On this pair of two post lifts, both cable sets were still within acceptable wear limits, but one cable showed early fraying near a pulley contact point — exactly where you’d expect wear to start given the extended static loading this shop does every fall. We also checked cable tension equalization between the two arms on each lift, since uneven tension is often the earliest sign something’s drifting before it becomes a safety issue.
Our general rule for cable inspection intervals on two post lifts used this way is simple: check them at every service interval, but also do a quick visual check whenever the lift comes out of an extended static hold. Fraying, kinking, or flat spots on a cable are not things to wait on. Cables are a relatively low-cost part to replace compared to the cost of a failure, and we’d rather sell a shop a cable set a season early than get a call about a dropped vehicle. This shop is now on a schedule where cables get inspected twice a year instead of once, given how they load the lifts.
Locks, Hydraulics, and the Parts That Fail Quietly
Cables get the headline attention, but the same annual visit turned up smaller issues that matter just as much for automotive two post lifts held under load for long stretches. One lift had a lock mechanism that was hesitating slightly before catching, which we adjusted rather than replaced — but it’s the kind of thing that gets worse under repeated seasonal storage cycles if ignored. We also topped off hydraulic fluid and checked hose fittings for seepage, since a slow drip that’s invisible on a lift cycling daily can become obvious after sitting loaded overnight.
