Explain your reasoning ? Why is it unsafe ? The lift is holding the car not the car jack . The car jack is not even touching the upper frame . It is only there for an emergency . It is in no way being used as a support of the vehicles weight . All it would do is give a person a few more seconds to get out from under the lift should it fail which it will not because of its design and locking mechanism . I only placed the car jack there as a second measure . Personally I have no reason to go under this car or any car . This was my first time using this system . With any new product it never hurts to go the extra step to keep your self and your unique vehicle safe . If you had this lift you would see how well it is built and how well the locking mechanism works .

I also watched the video, IMO it has a very secure locking mechanism. After the jack reaches its height, it then lowers automatically just a fraction so the locking "tab" locks into place. I think it would be extremely difficult for it to fail. And if anyone is concerned when under the vehicle, you could always add jackstands if you like to the front and or rear to feel even more secure.
This would work well in my garage....it is a neat video!!!

Having been a heavy eq. mechanic for mang years and working in other fields for many years, also related to mechanics, there is a requirement to use redundant safety measures. For an example when working on a piece of equipment that is elevated, or a piece of it is elevated. When a secondary safety is put into place it should bare weight. An example is a bucket of a front end loader. Newer equipment has a devise that prevents the bucket from lowering at full speed should a hydraulic line break, but you are still required to place a stand under the bucket to prevent it from lowering unexpectantly. Like wise with the lift in your picture. If the lifts locking mechanism should not fully engage and suddenly allow the lift to fall, it would probably just knock the jackstand out of the way. I would recomend for safety and piece on mind, that the stand be placed between the two lower frame rails with a block sitting on top and the two upper rails resting on it. It would also make the scisor lift far more stable.
I have seen the aftermath of too many failures and accidents resulting from the type of locks used and not employing a redundancy feature.

Good responses guys but believe me . Were I have the stand , it would not be knocked away . If you saw the Quick Jack unit you would understand . Again like I stated before , I have no intention of going under the car for any reason . It was just for a second safety measure . I almost lost both legs changing a flat tire many years ago and that put the fear of cars lifts and car jacks in me but you could safely crawl under this lift but I never will . If you were to go under the car then yes , many supports would be placed under the frame and other strategic places . Otherwise it is an amazing product that I plan to use for a long time . For simple wheel maintenance and even working on the LT5 top end it is great for your lower back not aching . I have to repair the window stop on the right door so the car will be on the lift again to save my lower back . It is incredibly stable and does not move when you push on it once your car is raised .
Anyway be safe guys oh and just so you know . More people die from car jacks than with this lift unit from quick jack .

I have and use a 5000 lb quickjack/I also have 4 by 4 timbers bolted together in a rectangular maner,that go under all wheels/tires/in addition to the quickjack/in high school I lost a friend who tried working under a car with only a bumper jack,never forget it only takes one accident to kill you

Tom. I sid not see that locking tab that would put my lock pin idea as intergrated.

May have used the wrong terminology GC, in some of the other videos they referred to them as safety latches. It appears that once the "cam" another word they used locks into place it would be difficult for it to reverse itself without getting the system ready to lower. But I agree that some form of a locking pin would be an additional form of security for sure.

Usually when I get under the C3's depending on where I am under the vehicle, I also have floor jack(s) under other frame members just in case. Of course that is in addition to jackstands already in place.

I have to agree also . Perhaps if they put an extra set of locking legs at the angled end of the lift . Then the lift would have that secondary safety stop and you would not need jack stands or any other bracing for safety sake .
Of course these lifts are used on grass/asphalt and cement bases so not sure how a secondary stop would work on grass or soft ground .
But I can tell you again that it is very very handy and easy to assemble and use tho there a bit heavy to manouver around .
Using it again today to switch out the snow tires on my Elantrash ...

Very sorry for the loss of your friend but that sounded very dangerous indeed .
If possible could you post a pic of what you built as your secondary safety support please .
Thank you
