When an RV and trailer repair shop on the edge of the Des Moines metro got their auto lifts installed for alignment work last year, the owner figured the hard part was over once the concrete anchors were torqued down. It wasn’t. Alignment lifts carry weird, unbalanced loads compared to a straight oil-change hoist, and long-frame RVs and travel trailers put more twist on cables than the average pickup ever will. A year later, that shop called us back for their first real service visit. Here’s what we found, what surprised them, and what every shop that does alignment work on big rigs should know before the first inspection ever happens.

Why an RV Shop Needed Alignment-Ready Auto Lifts Installed
Most general repair shops don’t think twice about alignment equipment, but a shop that handles trailer axles and RV chassis work has a different set of problems. The vehicles are longer, heavier at the ends, and often loaded unevenly with water tanks, propane, and cargo still on board when they roll in. When this shop called us about getting auto lifts installed, they specifically wanted something rated for that kind of asymmetric weight distribution, not just a standard two-post that assumes a centered load.
We walked them through a four-post configuration built for alignment work, since a four-post gives the technician a stable, drive-on platform with the rolling jacks and turn plates alignment work actually requires. Delivery logistics mattered here too — we always ask up front whether there’s a forklift on site or if we’re unloading by hand, because a long-frame alignment lift arrives on a flatbed and needs a plan before the truck shows up. This shop had a loading dock but no forklift, so we coordinated equipment ahead of the install date to avoid a wasted trip. That kind of planning is half of what makes an install go smoothly, and it’s the same conversation we have with every shop, dealership, or independent garage before we schedule a crew.
The Install Day: What Actually Happened
Getting auto lifts installed for alignment work is not a quick bolt-down job. Our crew spent the better part of a full day setting anchors, leveling the runways, and running the hydraulic and cable systems before ever powering the unit on. Concrete readiness came up early in the conversation — the shop’s floor was newer construction, which made anchoring straightforward, but we still checked slab thickness before committing to bolt pattern and torque specs, because a lift that isn’t anchored into adequate concrete will work itself loose within months no matter how good the equipment is.
Cable routing on an alignment-rated four-post takes more care than people expect. There are more pulleys, more equalizer points, and more places for a cable to rub if it isn’t threaded correctly the first time. We set tension by hand, ran the lift up and down empty several times to check for binding, then loaded it with a trailer to confirm the platform stayed level under an off-center load. By the end of the day the shop’s technicians were already running vehicles up and down, which is exactly the goal — a shop shouldn’t have to wait days after auto lifts installed on their floor before they can put revenue-generating work on them.
What Nobody Tells You About Cables in Year One
Cables are the part of a lift that quietly does the most work and gets the least attention until something goes wrong. In this shop’s case, the first sign of trouble wasn’t a failure — it was fraying. A technician doing routine maintenance noticed a cable starting to show individual strands separating near one of the pulleys, the kind of thing that’s easy to miss if you’re not specifically looking for it during a walk-around. We’ve seen this exact situation on a BendPak install for an ag operation north of Iowa Falls too, where fraying showed up early enough that we simply added a cable swap into the next scheduled service instead of waiting for an emergency call.
That’s the pattern we want every shop with auto lifts installed to understand: cables stretch and wear from day one, but the wear is gradual until it isn’t. On an alignment lift specifically, the constant micro-adjustments during turn-plate work put extra cycles on the cable system compared to a lift that just goes up and down for oil changes. We generally tell shops running alignment work to plan on inspecting cables at least twice a year, more often if the shop is running high volume.
Setting a Realistic Inspection Interval
There’s no single number that fits every shop, but we can give a starting point. For a typical general-repair two-post, annual inspection is usually enough. For an alignment-heavy four-post like this RV shop’s setup, we recommend stepping that up to twice a year, with a visual cable check by shop staff monthly in between. That doesn’t mean tearing the lift apart — it means someone spends five minutes looking at cable condition, checking that anchor bolts are still torqued, and listening for anything that sounds different than normal.
When we do a full inspection, we’re not just eyeballing cables. Our process includes lubricating moving parts, torquing anchor bolts back to spec, and adjusting cable tension so the platform stays level side to side. We also provide a written inspection report the shop can keep on file, both for their own maintenance records and for any insurance or safety inspector who wants proof the equipment is being maintained. That paperwork matters more than people expect — a shop that can show a maintenance history has a much easier conversation if an inspector or insurer ever asks questions about lift safety.
Why Alignment Work Is Harder on a Lift Than People Assume
Alignment work is uniquely tough on lift hardware because the vehicle isn’t just sitting still — it’s being adjusted, rolled, and shifted repeatedly while suspended in the air. Every turn-plate rotation and every jack cycle adds wear that a straight lube-and-tire shop never sees. For an RV and trailer shop, add in the extra length and uneven weight distribution of the vehicles themselves, and the cable system is doing more work per job than most shop owners realize.
We’ve found that shops who understand this upfront tend to budget for maintenance instead of treating it as a surprise expense. The shops that get surprised are usually the ones who assumed that because the lift passed its first annual check, it would coast for another two or three years without attention. Alignment equipment doesn’t work that way, and we tell every customer that gets auto lifts installed for this kind of work the same thing: build the twice-yearly inspection into your calendar the same way you’d schedule an oil change reminder.
What This Shop’s First Year Taught Us About Timing Service
By the time this Des Moines-area shop called us back, they were about thirteen months past their original install date — close enough to a year that the timing worked out well, but they admitted they’d almost forgotten to schedule it until the fraying cable caught their eye during a routine walk-around. That’s common. Shops get busy, the lift keeps working, and unless something visibly changes, maintenance slides down the priority list.
We’ve started recommending that shops with auto lifts installed for alignment or heavy-duty work set a calendar reminder tied to the install date itself, not to a vague
