that top cross piece is available in several lengths, from the manufacturer ,as is the post height,or you could rather easily custom make or modify the cross piece so the posts can be set in different increments apart.
obviously the base can be anchored to match and cables extended or lengthened as a bit more cost, but this current spread has worked ok, if Id had know about the choices Id have had an additional 8"-10"in width added so I had about 10 ft, or a bit more between,the posts, but like I said it worked OK
most lifts list the dimensions, the lift I bought I see is no longer listed, but it uses twin hydraulic rams and a chain drive and connecting cables
and was rated at 9000 lbs, its got a large base plate on each column and 8 3/4" bolts in each base into the concrete
