My friends at QuickJack are always talking about how safe QuickJack really is, and rightly so. If you’ve ever wanted a “quick and dirty” reference guide to QuickJack safety, I’m here to help. Three things make QuickJack safer than jack stands:
- A larger surface area = more stability
- Wider lift points
- Jack stand safety pins vs. QuickJack lock bars
For the sake of time, I’ll leave the engineering, steel quality and ease-of-use factors that make our car jack safer than floor jacks for another day. So, let’s get dirty. I’ll make it quick.
QuickJack’s larger footprint
You know how it’s a lot harder to touch your nose and rub your belly when you lift one foot in the air? When you do that, you’re effectively cutting your surface area in half (less balance). It’s the same thing with jack stands, without all the nose-touching and belly-rubbing. The reduced surface area means each stand is less stable on its own, and together, four jack stands are still nowhere near as stable as QuickJack.
If you use QuickJack the right way, its stability—from all directions—offers total peace of mind.
Wider lifting points
When you compare QuickJack’s rubber lifting blocks to jack stands, you see that the blocks offer more protection than stands. It doesn’t take an expert in physics to understand that more surface area means less pressure is put on an object. To rephrase Newton’s Third Law of Motion, there’s as much force coming back up as there is pushing down. In other words, that tiny jack stand is putting a lot more pressure on your vehicle than QuickJack, and likewise, the vehicle is exerting a lot of force on a smaller radius. Reducing pressure is crucial to keeping cars stable on car jacks or car lifts.
If you step on a nail, the nail goes through your foot. If you lie down on a bunch of nails, you’re okay. (Please don’t lie on a bunch of nails… “Jack” did NOT “tell you it’s safe.”) This video shows what we mean. Fast-forward to the 4:30 mark where sledgehammers get involved and things get… interesting.
Jack stand safety pins vs. QuickJack lock bars
Some jack stands feature a safety pin that ensures the slender pawl doesn’t slide out of place and drop your car. (Yikes!) In most cases, this works out just fine, and a safety pin (or even a ratchet system without a pin) is much, much safer than trusting little scissor jacks to hold the weight alone. Still, around 13,000 injuries and deaths occur yearly from everyday car jack and jack stand use. I think we can make this number way smaller. From a public safety standpoint, a stand that works “most of the time” just doesn’t cut it. Car jacks should be safe to use all of the time.
On the other hand, QuickJack makes things simple by eliminating a lot of little placement errors that are common with stands. When we first designed QuickJack, the safety arm needed to be manually set. Of course, the whole “QuickJack goal” is to create an all-in-one portable car lift and jack stand that is by far the easiest, most user-friendly product on the market. So, our engineers got to work and upgraded QuickJack to the SLX versions that you see today. Our updated tubular-steel arms automatically grab the welded-steel safety locks at the mid and max rise levels. All you have to do is watch (and let go of the button).
The mathematics behind QuickJack are extremely complex and brilliantly conceived. We can’t give away all our design secrets, but we’re already seeing cheapy (and often illegal) knock-offs pop up. Don’t trust ‘em. We don’t mess around or skip steps when it comes to safety. Car jacks and car lifts are our bread-and-butter products, and as a division of BendPak / Ranger, we’ve been refining our skills in this business for 50 years.
TL;DR: A portable car lift is safer than traditional jack stands, even when stands are used correctly. From an engineering perspective, QuickJack offers wider lift points, a larger ground contact surface area and a much more secure locking mechanism. Jack stands are prone to tipping and require extra care when working with them.
