Topic: Quick Jack

[rrocket]

I'm no expert on physics, but I would think that the weight of your car on the jack would make it pretty faking stable.  It'd take more than just leaning on one side to push the car off.

...my thoughts, at least.

Yep.

I've had a vehicle on 4 jackstands, its pretty freaking solid if done right. This thing would be even better, I would have no problem getting underneath.

Same.

I think many people here have never personally used a hoist or lift...so I understand some of the trepidation.

I've had a long box crew cab on a two post hoist....we chained that thing down like a mofo because that was sketchy AF. I guess yeah, if you've never been around them it might seem scary. That Contraption with the Suburban on it looks like something out of Final Destination, no spank you very much.

I'm totally stoked about this future thread.

I’m a mechanical engineer who has used hoists, lifts, jack stands, grease pits, etc etc, and I wouldn’t go near that thing.  You can have it.

I’ll take four independent jack stands over that thing any day of the week.

^^^Why?

[tenpenny]

^^^Why?

Safety and security.

The further apart the supports are, the more stable they are.  Look at the middle of that hoist, how far apart are they, compared to the length of the vehicle and it’s weight distribution?

Centre of gravity.  Physics.  Gut instinct.  Hydraulics.  Knowing how thick most concrete floors really are.  Safety factors.

You go ahead.  I’ll pass.

^^Yup.
It would make for an interesting thread though.

The first link looks good to me, it lifts the car at the lift points and the base appears to sit directly below just like a jackstand would.

The second option looks bad, as you lift the car higher it looks like the base gets closer and closer together. Looks like a tip over waiting to happen.

Hmmmm....Mechanical Engineers certified this and signed off on the Examination Certificate.  Are they full of it?

I saw this too just to         :  http://www.quickjacklift.ca/why-quickjack/quickjack-is-more-stable-than-jack-stands/

I work around all this crazy heavy stuff too...and I'd have no problem using it.

I want to see someone pushing on this with a car on it....like actually trying to tip it.

The locking mechanism looks bomber.

My brother bought one a few weeks ago, he seems to like his. I have not had a chance to see it in action yet. I have a different model, EZcarlift, no hydraulics, basically 2 giant screw jacks
 

[Marko]

Why the heck are they so expensive though? Is it just cause they're new? I'd spend a few hundred on this but I'm not paying $2000.

^^ that was my concern.  It's sizable (harder for storage when not in use), and you have to buy it in 3 boxes (each of which were like $599...IIRC).

I think this is specifically for those who are otherwise considering a two-post lift.  Those who just want to do the occasional tire change need not consider same.

I didn't think it was bad at all. Saw one where he had the ramps vertical up against a wall...

I saw the same thing on the quick jacks, made a holder out of 2x4's attache to the wall, not a lot of room at all.

Aren't the units rather heavy to move?  Not impossible, but not exactly featherweights...to lift it onto a wall...yikes.
