Title: Has anyone installed a car lift for storage/ car repairs and would recommend it?
Post by: Tinface on March 18, 2018, 03:49:05 AM
Gentleman,

I have very limited space at my house in the city: a 2 car driveway/ one car garage/ and one car carport with a garage door. Yes. It does suck. So I need to make the most of it until I move in a few years.

I am considering a 4 post lift so I can raise my GT350 up and drive another car I need inside underneath it, or pull the lower car out and work under the car on the lift. There are a bunch of lifts out there out now. I need a 4 post lift I believe.

Has anyone purchased a lift and set one up (or had something else set it up) and would recommend it? Or perhaps you don't like the lift you have and I should avoid it?

My measurements are really tight:

Height limitation: Their is a beam that is 9 (108") foot from the concrete the lift would sit on.
Width Limitation: The carport is 9 foot wide (108 ")
Length limitation:and 16 feet long(192")

That's roughly the size that the lift can be.

Thank you for your time.

Mark

A friend has one. Loves it. I'll borrow it if I need to do trans or exhaust work. I've kicked around getting one to put my mill, lathe and eelding stuff on to free up some space. Leno put about 10 in just for the storage space. Make sure to order the drip pan and sliding jack support so you can take a wheel off on the lift.

Rotary makes a great lift. It's a Global company within a Fortune 500 Company.
The parent Company is Dover Corp.

I'm not sure on dimensions but you can google it.  Many varieties.

You don't want one of the cheap ones made overseas...
Remember,..you will be standing under it....
You get what you pay for.

I give Wildfire lifts a BIG thumbs up.  I researched them all and decided to buy theirs for many reasons as it is a great lift with easy set up.  Heavy duty at an affordable price and you wont be sorry going with them.  You also talk and buy directly from the owners.   Call Brad at 763.445.9143

I suppose it would depend on what you planed on parking underneath.Sorry to report that I just measured a 66 GT350 and then lowered a lift with a car on it ( but not one underneath for safety reasons ) to the car height measurement plus inch. The total measurements included the lift platform (all makes are about the same in that respect). The total with the car on top was over 9 ft.  It wasn't even close.  I think that you will find that a 9ft ceiling will not let you park anything but a low profile car underneath if you had a 66 GT350 or equivalent on top. . You could still gain storage for maybe lawn equipment etc. but certainly not two equivalent 66 GT350's .

I bought a 9000lb capacity Revolution which is made by Rotary.  Unfortunately it won't fit within the space you have to work with.  Maybe a trimmed down version is available from some manufacturer but they all seem to be about the same size and my posts are basically 10' x 16' center to center.  Below is a link to the model I bought and a picture of my lift.  One of those things you'll wonder how you ever lived without one once you get one.  Good luck!!  Edit...just looked at the Revolution 8000lb lift in the link and it looks like it will fit in your space but unless your other car you want to park underneath is a GT40 I don't think the height will work for you with either lift.

QuoteI have looked at the Advantage 4 post lift.

I have a 9000 XLT Advantage lift that I use to store my 69 GT350 on. It keeps it out of reach of my 21/2 year old grandson and also out or reach of me when I am carrying  a large item and bump into one of the posts. I looked at a lot of lifts and decided to go with Advantage after seeing one at Hershey a couple of years ago. I would like to have a 2nd one so I wouldn't have to shuffle cars around when I need to use the lift to work on another car. I purchased the XLT for the extra height... 7 ft of clearance. Another thing I like is the posts are square tubing not a C channel with sheet metal for the cut outs for the safety stops and have a square tubing collar around the post.
Another thing I like about it is the casters that come with it allow you to roll it around the shop ( I also ordered the 110V pump so I could plug it in anywhere I wanted vs the 220V... it is a little slower but the advantage outweighs the disadvantage for me ;))

Don't underestimate the value of installation.

They aren't complicated but they are heavy.

Also. If you are wiring for 110V, use a 30amp breaker and wire. Makes a huge difference.

+1 on the weight!  They are extremely heavy.  I had my 4 post installed by a local shop, even though I ordered the lift from out of state.

Side note - you can order and have lifts delivered unassembled; HOWEVER, most manufacturers will only deliver to a loading dock of some sort, given the packaging, etc.  So, I couldn't have the setup delivered directly to my home - I had to have mine delivered to the local shop setting the lift up.

I, too, have a very limited interior garage height.  I thought I had 10' ceilings; which would have been great.  However, my ceiling is 9' 4" a the lowest point.  I was able to make the lift work, but much like Bob G mentioned, it really depends on what you have underneath AND on top. 

Another issue to tackle is not just the over and under space, but you also need to figure out upper and lower clearances based on the manual locking slots.  And, you also have to give yourself at least an additional 3 inches once the lift is resting on the locks, as you'll need about 3 inches to raise the lift to off the locks to release the locks and then lower the upper car.  I remedied this by measuring everything ahead of time (you an go online and find the heights at which the locks will set), and I ended up having 3/4" thick aluminum cut to the size of the post feet and placed under the post feet to allow the exact height required above and below.

Hope this helps!

I have a Backyard Buddy. Very nice lift....I too had some height limitations.  They were great to work with and actually custom made the lock heights for my lift....I purchased the drip pans, and a rolling jack stand.   I recently purchased a Bend Pak RJ 45 rolling bridge jack for m,y lift as well ........Kevin

My brother and I bought a 4 post lift for his garage about a year ago.  We purchased it in Delaware because there are no sales taxes there.  It was surprisingly cheap.  I do not remember exactly how much $ but it was less that $2000.  We installed it ourselves. It is very easy to install but as other have mentioned there is one very heavy piece.  The one runner that has the hydraulic ram in it was very heavy.  But we managed it with the two of us a woman and a couple dollies. The instructions that came with it were marginal but there was a great YouTube video that helped out a lot.  The unit we bought was from Atlas Equipment.

My car has been on the lift the last two weeks as I have been swapping my transmission.  It works out really well for that since it is in the center of the car so the rails do not get in the way.  My brother also purchased two couple hydraulic jacks that ride on the rails and are used to jack the tires off the rails for brake work and such.

My son and I put my Advantage lift together in 1 1/2-2 hrs. He is stronger than I am and insisted that we manhandle it even though I have a fork lift and an engine hoist 30' away. When he is my age he will learn to work smarter not harder  ::)  I also have a loading dock which made delivery easier...

That's another great point I forgot to add...garage door clearance.

I ended up getting a new low profile door system.  Basically, they used the same door, but the rails are now only inches from the top versus feet.  And, it comes with a side jack opener (mounts along the side of the door versus hanging from the ceiling). 

I also had to mesure where the door would stop when fully retracted, so that the door wouldn't slam into the roof of the upper car or the back window.  Luckily, the door stops retraction before it reaches the back window on my upper car when raised.

Hi Steve here is my lift. My 10 foot 6 inch ceiling works well except I bent the antenna top on the T Bird when it hit the ceiling. I just need a few more inches. I had to raise the garage door as you can see the track is almost at the ceiling. Also because that door is a double size I had to put a stronger industrial type lifter to raise the heavier door. The Shelby fits nicely with about 14" clearance on each side and 10 "roof clearance at the top.
Just don't forget to duck when you get out of your car. Working on a car I still have to duck under the side rails to get under the car but there is ample room to work on the car underside once under it.
I had it delivered. It arrived on a flat bed roll back. They lowered it onto wheels and rolled it in the garage. Leveled it, fine tuned the lift and it was done.
I saw several different ones at a local car event and decided this one was the best for me. It cost a bit more but looked to me better for my needs. I have had zero problems with it. I have had it about 6-7 years.

Thanks Les for the photo.  I have a T-Bird also so the picture is super swell.  I would have to raise the garage door as you have done.  I already have the industrial lifter so that box is checked.  Just need to do some more measuring.  I am just TIRED of putting them both on jack stands.  I am getting OLD!!!

Thanks again,

Gentleman,

I have very limited space at my house in the city: a 2 car driveway/ one car garage/ and one car carport with a garage door. Yes. It does suck. So I need to make the most of it until I move in a few years.

I am considering a 4 post lift so I can raise my GT350 up and drive another car I need inside underneath it, or pull the lower car out and work under the car on the lift. There are a bunch of lifts out there out now. I need a 4 post lift I believe.

Has anyone purchased a lift and set one up (or had something else set it up) and would recommend it? Or perhaps you don't like the lift you have and I should avoid it?

You might want to look at this portable unit , considering your height restrictions
https://www.bestbuyautoequipment.com/2-post-portable-car-lift-system-dannmar-maxjax-p/dannmarmaxjax.htm

My measurements are really tight:

Height limitation: Their is a beam that is 9 (108") foot from the concrete the lift would sit on.
Width Limitation: The carport is 9 foot wide (108 ")
Length limitation:and 16 feet long(192")

That's roughly the size that the lift can be.

Thank you for your time.

I believe I read Bendpak is made in China now but they were offering a "Patriot" brand to compete with Back Yard Buddy.  Mohawk is about the only, if not the only USA made lift if believe.

That is cool, but it looks like it will only work with double or triple width doors, not multiple single doors with pillars between.  I have 3-10' doors with 4' pillars between them.  I built it that way to have spots to put my tire machine and wheel balancer

I, too, have a very limited interior garage height.  I thought I had 10' ceilings; which would have been great.  However, my ceiling is 9' 4" a the lowest point.  I was able to make the lift work, but much like Bob G mentioned, it really depends on what you have underneath AND on top. 

Another issue to tackle is not just the over and under space, but you also need to figure out upper and lower clearances based on the manual locking slots.  And, you also have to give yourself at least an additional 3 inches once the lift is resting on the locks, as you'll need about 3 inches to raise the lift to off the locks to release the locks and then lower the upper car.  I remedied this by measuring everything ahead of time (you an go online and find the heights at which the locks will set), and I ended up having 3/4" thick aluminum cut to the size of the post feet and placed under the post feet to allow the exact height required above and below.

Hope this helps!
