A car lift for storage sounds simple until you’re staring at a low-slung European sedan wondering if the arm restraints are actually doing their job. We install and service lifts for European-marque specialty shops around West Des Moines that do restoration and metal work on the side, and almost every one of them has a mechanic who swears the safety cams are “basically decorative.” They’re not. We’ve seen what happens when a car lift for storage gets treated like a toy instead of a piece of load-bearing equipment, and it usually happens on the exact night nobody’s in the shop to hear the bang.

Myth: Arm Restraints Are Just There to Keep the Arms From Swinging
This is the single most common misunderstanding we run into when we quote a car lift for storage job in the West Des Moines area. Arm restraint pins aren’t a convenience feature to stop the arms from drifting when the bay is empty. Once a vehicle is up and the lift arms are loaded, those pins (or in some designs, a mechanical lock) are what keeps the arm from sliding out from under the vehicle if there’s ever a pressure loss in the hydraulic system. On a storage lift specifically, where a car might sit loaded for weeks at a time for a restoration project, that’s not a hypothetical.
We’ve walked into European specialty shops doing metal work and paint where the technician pulled the restraint pins “because they were in the way of the fender” and never put them back. On a two-post lift especially, that turns a stable four-point hold into a lift relying entirely on friction and arm geometry. Add a low-clearance BMW or Porsche with different pickup points than a domestic sedan, and the margin for error shrinks fast. If you’re using a car lift for storage for a project car that isn’t moving for a while, the arm restraints matter more, not less, because nobody’s climbing under it daily to notice something shifted.
Myth: The Safety Cams Engage Automatically No Matter How You Lower It
Safety cams (or safety locks, depending on the brand) only do their job if the lift is lowered the way it’s designed to be lowered. On most two-post and four-post lifts we service, you have to lift slightly past a lock point and then lower onto it to hear the cam engage. Operators in a hurry sometimes stop the moment the wheels look level and call it good. That means the full weight of the car is riding on hydraulic pressure alone, with the mechanical backup never actually engaged.
We tell every shop the same thing: listen for the click, or better yet, watch for it. On a car lift for storage, this matters even more than on a service lift, because the vehicle might not get touched again for days. If the cam never locked and the seals develop even a slow leak overnight, you can come back to a car sitting nose-down or resting on a fender instead of the frame. This is one of the most preventable failures we see, and it costs nothing to fix — it just requires actually confirming the lock instead of assuming it happened.
Why Storage Use Is Different From Daily Service Use
A lift used for daily service gets loaded, worked on, and unloaded within an hour or two. A car lift for storage might hold that same vehicle for a season. That changes what you should be checking and how often. Hydraulic cylinders that would show a slow seep during a quick service job get a lot more time to leak down when a car sits parked overnight, week after week. We’ve fielded calls about exactly this — a residential lift with a leaking cylinder seal on a car that had been sitting for a while, where the owner didn’t notice the slow drift until the vehicle was noticeably out of level.
For restoration and metal work specifically, cars often come apart while they’re up on the lift — fenders off, doors off, sometimes the whole body shell resting differently than it would with everything bolted on. That changes the center of gravity and how the arm restraints and pads are contacting the vehicle. We always tell European specialty shops to re-check pad placement and restraint engagement any time the car’s structure changes while it’s parked up top, not just when it first goes up.
Picking the Right Lift for Long-Term Storage in the First Place
Not every lift on the market is really built for a car lift for storage application. A basic service lift rated for quick in-and-out work can technically hold a car for weeks, but the arm restraint design and cam engagement points matter more when duration is longer. We steer home-garage and small-shop customers toward BendPak and Atlas lifts for this exact reason — the engagement points are forgiving and well-documented, and parts for arm restraint pins and safety cam kits are easy for us to source when something wears out.
For European cars specifically, low ground clearance is the recurring issue. Standard ramps and stock arm pad positions don’t always clear a low front splitter or aftermarket suspension. We’ve quoted extended and low-profile ramp upgrades for exactly this reason on cars that ride low and needed to sit stored on a lift rather than parked on the floor. If you’re setting up a car lift for storage and you already know the vehicle sits low, tell us that up front — it changes which ramp and pad configuration we recommend before the lift ever gets bolted down.
What We Actually Check on Restraints and Cams During Install
When we install a car lift for storage for a shop doing restoration work, we walk through arm restraint engagement with whoever’s going to be running the lift day to day, not just the owner. We physically point at the pin, show them the hole it needs to seat in, and have them run the lift up and down themselves at least once before we leave. Same with the safety cams — we want them to hear the click, not just take our word for it.
We also check that the concrete anchoring is solid before we sign off, because arm restraints and safety cams don’t matter much if the whole post is working loose. This is especially relevant in older shop buildings around the West Des Moines area with slab that’s seen decades of use. A car lift for storage is only as reliable as its weakest connection point, and that’s often the anchor bolts, not the arms themselves.
Maintenance Habits That Keep a Storage Lift Safe Long-Term
Most of the lift failures we get called out for aren’t manufacturing defects — they’re maintenance gaps that had months to grow. For a car lift for storage, we recommend a monthly walk-around even if the car up top isn’t moving: check that the restraint pins are still seated, listen for any hiss or drift in the hydraulics, and glance at the pads to make sure nothing’s shifted. It takes five minutes and catches almost everything before it becomes a real problem.
We also recommend keeping a basic log of when the lift was last serviced and when cylinder seals were last checked, especially for shops running multiple lifts. It’s easy to lose track of which lift is due for attention when you’ve got several bays. A quick note with the date goes a long way toward catching a slow leak before it turns into a car sitting crooked on a Monday morning.
When to Call Instead of Troubleshooting It Yourself
If an arm restraint won’t seat, if a safety cam isn’t clicking, or if a car lift for storage seems to be settling even slightly overnight, that’s not a wait-and-see situation. We get calls fairly often from shops asking about lifting pads that have worn down or safety hardware that’s four years old and finally showing its age — that’s a normal replacement, not an emergency, but it needs to happen before the next long-term storage cycle, not after something slips.
We stock arm restraint pins, safety cam hardware, and pad kits for Rotary, Challenger, BendPak, and Atlas equipment, and we can usually get replacement parts out fast once we know the model number. If you’re not sure whether your current setup is safe for long-term storage use, we’d rather answer that question over the phone than have you find out the hard way with a car up in the air.
