Any mechanical or hydraulic lift can fail, Id suggest use of a couple of the less expensive 6 ton rated jack stands be used under the car frame once the cars raised up on the lift as an additional level of cheap but potentially vital security, and yes I'm well aware the safety bar and ratchet in theory prevents the lift from un-intentionally dropping

spending less than $70 on sale, for 4 6 ton jack stands that will insure the car stays up if the lift were to fail, is a damn cheap price to insure you don,t find out the hard way about mechanical device failures

personally I prefer using 4 12 ton jack stands , solidly placed on the car frame with the jack stand bases on a level concrete floor.

5/8 in. x 4-3/4 in. Clevis Pin available at home depot for $4 each

be darn sure you, try different heights on the jack stand to find,
where it gives you the best compromise for clearance,
and easy reach under the car / truck with a mechanics creeper ,
before drilling for safety pin locks

I doubt theres ever been a single year pass without my hearing about someone getting either hurt, killed or having a very close call.
well no mater how many times , I point out this fact, there's always some guy who thinks a floor or bumper jack will be OK to support the car, while he does a quick repair, or some guy who jacks the car up and slides a CBS block under the wheel to support the car , rather than using decent 6 ton-or much better yet use of 4 12 ton jack stands that have a wider base making them less likely to tip and a larger strength safety margin due to much more masive component size, and having the ability to think coherently, long enough to realize that you can,t safely jack up a car on non-level ground or on soft dirt or asphalt, simply because the jack stands can slowly sink into a soft surface.
if your going to use jack stands on soft dirt or asphalt youll want to have cut enough 18" -or 24" square 3/4" thick marine plywood squares to place under the jack stand bases
and you should always place wheel chocks behind both rear wheels if your only placing the front of the car up on jack stands.
I bring this up simply to remind you guys as one of the local guys was seriously injured when he jacked up his car and placed the front wheels on concrete blocks, without wheel chocks behind the rear wheels , he then proceeded to remove the drive shaft, and when he did the car rolled off the blocks crushing a few fingers on one hand. seconds before he was under the car, and if he had not been scooting out when the car fell, he might have been killed due to lack of thinking about the potential dangers.

they don,t even list the price...you know its amazingly expensive

having only the front or rear of the car supported is frequently a bad idea, as a non-level car has a much more likely tendency to roll or fall.

personally I prefer using 4 12 ton jack stands , solidly placed on the car frame with the jack stand bases on a level concrete floor.

its also a very good idea to build and use wooden car safety support stands under the wheels
(notice theres a 2 x 4 in front and behind the wheel )
making it very unlikely the car will roll off these wooden supports ,
these supports can be fabricated very cheaply, if you can find a wood scrap pile at a local construction site.
but even with new wood they don,t cost too much to fabricate.

I was reading just today where a guy was working on his custom car and was under the car,
with the tires on the car on supports like the photo above rather than 12 ton jack stands on the cars frame,
when a component of the air ride suspension failed,
dropping the cars height just enough that he was trapped and could not breath..
yeah it was fatal before he was found.
I lost a second friend to being crushed to death under a vehicle.
He was a 58 year old just retired fire fighter and a veteran of dozens of builds.
Crushed apparently by air ride that must of dropped unexpectedly.
By far one of the best people Iv ever known

As we all know in the back our minds this happens ... probably everyday somewhere.
Obviously please please keep this in mind people
yeah it may take a couple extra minutes, but its a damn sight safer to use 4 12 ton jack stands on the cars frame and work on a level concrete surface.
and yeah under the tire supports are great but not always sufficient,as the tires and suspension are not as solid as the frame for supporting the car.

btw
one of the guys locally had only the front tires up on supports to do an oil change, recently,
he decided to check brake pad wear, he used his floor jack to lift the one side just a bit higher so he could remove the one tire,
as soon as he used a breaker bar the car rolled off the supports,
and tipped over the floor jack, luckily he was not under the car,
at the time but the car rolled out of his garage and into his wife's car door parked in the drive way.

BTW
Ive seen several people burn down their shop or garage,
as a result of not having a decent fire extinguisher handy
Thinking things through, taking simple precautions ,
and thinking about what might go badly ,
can save you from a great deal of pain,expense and
grief
