Usually the standard speed offered with each lift table is satisfactory for most applications, but occasionally faster speeds are required. The formula for horsepower is
Work/550 x time = horsepower required
Work = force x distance
Therefore, the shorter the amount of time to do the work, the more horsepower needed.
As horsepower goes up , so do the electrical controls, hydraulic pumps 
and valves. Costs often rise quickly.
