One column of a two column auto lift will travel at twice the speed,

rated two column lift carries 5,000# hanging several feet off the
column, and with safety margins for overhead lifting (5:1?). Using half
an auto lift also provides a complete set of spare parts.

The fastest lifts I saw were too slow by a factor of 5. I only showed
one column, but there are two.


Simple, higher pump output.

Exactly, in the new application you'd replace the basic hydraulic power
pack normally mounted on the column, with a "real" industrial hydraulic
power unit with a large tank and probably 10HP+ motor rated for
continuous duty.
