lift placement

[that-guy]

i am in the final planning stages for building my garage but first need to figure out concrete needs. i am going with 4", 3500psi, fiber and rebar, but with a 6" x 4' section the length of the garage for lift provisions.

the building is 30' deep and 40' long with 3 bays and want the option of putting a lift in any one of the 3 bays.

the question, where should i place the lift? i am going with 30' deep so i'll have plenty of space in front of and behind my full sized truck with the bay door closed. so should i center the posts in the garage or offset a little forward??? what is the general rule of thumb?

Make sure the concrete guy doesn't put any control joints close to where a lift column may be placed.

i figured that was pretty self explanatory, more so looking for measurements

Bend Pak lists 4" at 3K is good enough for a 2 post lift under 14K. Anything else is over kill. Adding rebar is good but make sure it doesn't pass thru a spot where you will want a bolt for the lift. You don't really need to throw that 4' of 6" in there, save your money.
The other thing is to keep your OH doors at least 4' off the inside walls. Putting a lift in one of the end bays will eat up a lot of wall space and make it difficult to walk around the lift on the wall side.

all good information, and i thank you for that, but still doesn't answer my question

Push it to the back. Reason being the OH door will hit the vehicle when it is up on the hoist if it is too far forward. Raise the door, park your vehicle so there is room to the fully open door and position your hoist accordingly.
The other option, if your ceilings are tall enough, is to install high lift door tracks, then it doesn't matter where the hoist is as long as you can close the door.

ceiling height is a non-issue, and the doors are roll-in drum type, so also a non-issue

i know that you generally put a car on a lift with the front end closer than the rear end to the posts itself for stability because with a front engine vehicle, it is front heavy. i am trying to make sure that with a full sized, quad cab, long bed truck, and the posts dead center, that i'll have adequate space front and rear

Are you getting a symmetric or asymmetric lift? That makes a difference in the loading position of the vehicle.

 

[firebirdparts]

I think you want the lifted car centered in a 30 foot space. If you get an assymetric lift, then you'll need to factor in some sort of fudge factor. You'll get some layout instructions from the manufacturer. A symmetric left would be centered in a building that size.

I have heard a rule of thumb to place 2-post lift columns 12 feet from the wall so you have room to work in front of a vehicle. But asymmetric changes that a little

[/url][/IMG]I have a 30x40' and my Bend Pak(non asymmetric) is set about 1ft. forward away from the door off center and is just right for my needs. It is in the farthest stall left looking at the front of the building. Would not want the posts sticking up in a center stall and having to walk around them all the time. There have been full size crew cab trucks on there, too.

In my 30' deep x 38' wide 3-car, my two 4-post lifts when the ramps are attached are about 3 ft inside the doors. This gives me plenty of room forward of the cars for cabinets, benches and work area. The lifts are on each end bay and only 24" or so from the walls which is enough to walk by.
