We got a call a while back from a European-marque specialty shop in southwest Iowa that had just stacked a second car under a third on their vehicle storage lifts and wanted to know why the safety locks kept chattering instead of engaging clean. The answer wasn’t a bad lift. It was a myth that gets repeated in every import shop we’ve ever walked into: that the arm restraint straps are optional once you know how to “feel” a car settle onto the pads. That habit is how a Porsche or an Audi ends up with a cracked splitter or worse, a lift that never fully locks. Vehicle storage lifts are only as safe as the way you use the arm restraints and the safety cams every single time, not just when a customer is watching.

Myth #1: Arm Restraints Are Just for Show
The single most common mistake we see on vehicle storage lifts in European specialty shops is treating the arm restraint straps as an afterthought. Techs who grew up on domestic drive-on lifts sometimes never developed the habit, and low-profile European cars with tight ground clearance make it worse because the arms have to swing in at odd angles to find a lift point. Without the restraint engaged, the arm can walk out from under the pad as the vehicle settles, especially with a full tank of gas or a heavier trim shifting weight during the raise.
We tell every shop the same thing: the restraint strap isn’t there to hold the car up. The safety cams and the mechanical locks do that job. The strap’s job is to keep the swing arm from rotating out of position while you’re getting the pads set, before the cams have anything to catch. On a car stacked underneath another vehicle on true storage lifts, there’s zero margin for an arm creeping. We’ve re-torqued and reset more than one shop’s setup after finding restraints looped but never actually cinched down, which does nothing.
Myth #2: If It Clicks Once, It’s Locked
A lot of techs raise the lift, hear one click from the safety cam, and call it good. On some vehicle storage lifts, especially older BendPak or Atlas units that have seen years of daily use, one click doesn’t mean the cam has fully seated into the notch. It can mean the cam caught the leading edge and is riding on a partial engagement that will slip under vibration or load shift.
The right habit is to lower the lift onto the lock after raising past your target height, and physically confirm the cam bar has dropped into a full notch, not just tapped one. We’ve walked technicians through this on site visits in southwest Iowa more than once, because the difference between a full engagement and a partial one is maybe a quarter inch you can’t always see from where you’re standing at the controls. Get in the habit of a visual check from the side of the lift every time, not just a listen for the click. It takes ten extra seconds and it’s the difference between a stored car and a insurance claim.
Myth #3: Daily Maintenance Doesn’t Apply to Storage Lifts
Because storage lifts aren’t cycling a car up and down all day like a service bay two-post, a lot of shops assume they don’t need the same daily attention. That’s backwards. A lift holding a car parked for weeks or months is under constant static load on the same cable, same pin, same lock point, with no movement to reveal a developing problem the way daily cycling would.
We recommend a quick visual walk of every storage lift at the start of the day, even if nothing’s moving. Check that the safety cam is still fully seated, that the arm restraint straps haven’t loosened from vibration in the shop, and that there’s no visible sag in the cable path. On four-post and scissor-style storage setups we service, the cable and pulley system is doing quiet, constant work you won’t hear complain until it’s already stretched or frayed. Five minutes a day beats an emergency call.
Getting the Locking Mechanism Habit Right From Day One
New techs and shop owners setting up vehicle storage lifts for the first time tend to learn shortcuts from whoever trained them, good or bad. If the person who showed them the ropes skipped the restraint strap or eyeballed the cam engagement, that becomes the shop standard. We’d rather train it right the first time during install and walk the whole crew through the locking sequence, arm restraint, safety cam, visual confirmation, before the first car ever gets parked.
This matters even more with European cars because of how tight the lift points can be and how much bodywork damage a bad drop causes compared to a domestic truck. A shop running a mix of low sports cars and taller SUVs needs the crew comfortable adjusting arm position and restraint tension for each vehicle, not applying one setting to everything. We build that into every install we do, and it’s worth revisiting with your team at least once a year even if nobody’s had an issue yet.
What Rust and Age Do to Locking Hardware
We’ve serviced a Challenger heavy-duty lift that had been sitting in a shop that suffered a fire, and the equalizing cables, lock cable, and pads had all hardened or rusted from the heat and moisture exposure. That’s an extreme case, but it illustrates something true of any vehicle storage lifts sitting in an Iowa shop through humid summers and salty winters: the lock cable and cam hardware corrode slower than you’d think, right up until the day they don’t catch.
If your storage lifts are more than a few years old and you can’t remember the last time someone inspected the lock cable and cam pivot points, that’s worth a service call before it’s worth a claim. We check this on every recertification visit, and it’s often the first thing to show wear on a lift that otherwise looks fine from the driver’s seat.
Space Constraints and Why Restraints Matter More in Storage Setups
Vehicle storage lifts get installed in tighter footprints than service lifts almost every time, because the whole point is fitting more cars into the same square footage. That tight spacing means less room for an arm to swing wrong before it clips a neighboring vehicle, a support post, or the shop wall. In a southwest Iowa shop running a stacked storage setup for customer cars over winter, we’ve seen how little clearance there is between a stored vehicle and the lift columns next to it.
That’s exactly why arm restraint discipline matters more here than almost anywhere else in the shop. A creeping arm on a service lift with open floor space around it is a problem. The same creeping arm on a storage lift wedged between two other stored vehicles is a much more expensive problem, and one that’s entirely preventable with the strap actually cinched every time.
When to Call for Service Instead of Working Around It
We hear from shops fairly often after they’ve already been working around a locking issue for months, propping a cam, skipping the restraint because it’s stuck, or trusting a lift that clunks instead of clicking. None of that is a fix. If the safety cam isn’t seating clean, if the arm restraint mechanism is bent or frozen, or if the lock cable shows any fraying, that’s a parts and service call, not a workaround.
We stock arm restraint hardware and lock cable components for the storage lift brands we install, and we’ll walk you through diagnosing which part is actually failing before you spend money guessing. A quick phone conversation about what you’re seeing usually tells us whether it’s a five-minute adjustment or a part that needs replacing before the lift goes back into daily use.
