Great video, thanks for posting!
Thanks for the comment!!
I've had my 7000 lb QJs for a few years, they work great. The reservoirs hanging off the sides of the cylinders are accumulators that are pressurized to prevent cavitation (air bubbles formation) and compensate for thermal expansion in the hydraulic fluid, and do not provide added "oomph". My jacks have always lifted and dropped at the same rate. There's got be a proportioning valve in the valve body to ensure that the pair of jacks stays synchronized... otherwise there's nothing preventing a slightly off centered load from tilting. If your QJs are lifting at different rates there's something wrong in your valve body.
They lift at the same rate, thanks for the comment!
From what I understand is that the off side air cylinders provide (air) pressure against the piston when the frame lowers. One of the air cylinders was also not holding pressure and the frame did not lower completely. The valve stem was sealing fine so I used some soapy water to trace down the leak. It turned out to be the blue seal on the piston rod of the main cylinder.
Thanks for the comment! Glad it is for lowering I can always give them a push to lower too!
Good job.
Thank you!!
Do you notice any wear on the bottom of the quick jacks from sliding them around? I’m interested but would be on pavement for most my work. I wish they came with bearings on the bottom. I’m just concerned the scraping would lead to eventual rust etc.
Definitely some wear from moving around, would have been nice if they had rubber feet or something. However I really don’t think rusting will be an issue, especially if your floor is dry.
I’d be really cautious about stopping on the way up before it clicks past a safety. I think this is more likely if one side of the car is heavier: I had one side start lowering while I was triple checking like you. That caused fluid to be pushed to the other side, causing the other side to go up. Clicking the button to try to resume lifting just made it worse. Due to the car tilting, the blocks (I had 2 blocks stacked) shifted and the car ended up crashing off the blocks and onto the now-tipping QJ. The QJ narrowly missed popping out from under and causing the car to fall off the high side, which would have led to the QJ nailing the doors. Luckily I had pushed the QJs as far in underneath as possible. Then I was left with the predicament of how to get the car back down. The ordeal took years off my life! I saw a video of someone else this happened to while he was filming.
Oh my that is very scary!!! Glad nothing really bad happened or any injuries, I will keep this in mind for the future!!!
Just a couple of questions: Did you raise this lift to it's maximum usable (lockable) height in this video? Also, how far forward does the car move when you raise it on the lift?
Thanks for taking the time to make this video - it's well done and very informative.
It's obvious in the video, if you watch it, that he did not lift it to the max. He said it would be nearly high enough to sit under it at max. He also showed locking it at the first lock, or around half way up.
I will have to rewatch and see but if memory serves I don’t think I raised it fully. The car does move forward or backward depending on the jack orientation, I would say about 12-16” of movement occurs between the ground and the highest lifting position. Thank you for the comment and glad it was informative!
air cylinders are for last few inchs when lowering. realy not needed i have same set i aired them up one time new that was it never did it again
Thanks for the information that is very good to know!!!
One thing I absolutely don't like about these lifts is the locking mechanism. Only 2 locking points, very tiny, seem totaly unsafe. Also you can't unlock them on both sides at the same time, not very secure. The locking mechanism is what saves your life in case of a hydraulic failure so it should be absolutely safe in operation at all time. Is it able to deal with the weight of the car if the hydraulics are cut? I doubt it.
That is my concern as well, it does seem like the locking points are strong enough but I agree, doesn’t feel super safe.
@@matt-diy Just viewed a video from "The Automotive Fanatic" channel about the same lift. He didn't lift his car up to the first locking point, had a hydraulic failure and the car fell to the ground on one side while the other was still up, incredibly dangerous because the car moved sideways and the other side just blew right from under the car to the side. It clearly demonstrates the lack of adequate locking points. If the total height is about 23 inches, I'd say it would be safe if it had locking points at every 4 or 5 inches. In that video he later used jack-stands because he didn't feel safe under the car, that says it all.
@@simduino Yeah I agree I think there should be more locking points for sure. I will have to check out his video.
@@simduino Okay, after viewing his video that was very bad user error, however, if there were additional locking points that would not have happened. However, it is very important to raise both beyond the locking point before lowering the vehicle and that was a massive mistake on his part.
