<div dir="ltr">:-) I have spent many an hour under cars on jackstands. On hindsight, in California, not a good idea. I now almost exclusively use ramps if I can. If I can't, I ALWAYS have something bigger than me under there too. I have this large, long block of wood that some contractors left once. It's added protection. I put all wheels under too - including all the jack stands and floor jacks under there.<div><br></div><div>Funny you mention sore arms. There are many times when I've been under a car working away on my back when my arms just burn from holding them up for too long.<br><div><br></div><div>I bought my lift solely for car storage purposes. Being able to work under cars is just an added benefit. For me, in suburbia with a tight HOA, I have my existing garage space, with no option to build out a wider, longer garage. So if I wanted more cars in the garage, they had to go up.</div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jan 29, 2016 at 1:46 PM, Tom Witt via Tigers <span dir="ltr"><<a href="mailto:tigers@autox.team.net" target="_blank">tigers@autox.team.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>There would be a difference between a car falling off a lift (or the lift
vertically collapsing)..., and the lift falling (tilting) over with the car
still firmly attached. It would seem the floor structure for a two post
lift needs to be seismically substantial as compared to a four post lift.
I don’t think the issue is the two post lift collapsing (vertically) as much as
it is simply falling (tilting front-back) with the failure at the floor
attachment. Tripods have at least three legs for a reason.</div>

<div>As a lifetime suburbanite I struggle to comprehend the need for a
lift. Are there really that many places that are width/depth challenged
and yet have substantial height to elevate the car – especially for stacked
parking? If you are replacing exhaust systems, brakes, transmissions on a daily
basis sure they make sense. Maybe it is just my perpetually bad back, but having
to stand, look up and work with arms up seems like torture compared to putting a
car on jackstands and lying on the floor to work. A sheet of foam core makes a
nice, cushioning insulator. </div>

<div>Figure a Tiger at 2500 lbs. on a 9000lb rated lift. Should be pretty
secure. The guy who installed mine said they are actually tested at twice the
rated capacity. I think as long as the Tiger isn't shaken off the lift then it's
a pretty good bet that the lift won't collapse. </div>

opened the door, all was well. 4-post lift. MAYBE someone can convince me that
a 2-post is as stable under such circumstances...<br><br>Larry
