NSTALLATION
The standard foundation for the Ball Lift consists of two 2 x 6 x 18-inch boards over a
concrete subfloor.
While shims are provided to level and raise the Ball Lift to the
required height, you may need to plane the boards and/or use additional materials to
achieve the 14-7/16-inch (367 mm) required distance from the
bottom
surface of the
Ball Lift base plate to the
top
surface of the approach.
Depending on the length of your approach, you may or may not have the ball rack
overhanging the end of the approach.
To determine the overhang at your center,
perform the computation below using the numbers from your center.
IMPORTANT!
The position of the ball lift on the approach in the following calculation is based on a
standard QubicaAMF underlane track installation that results in the end of the track being
125-7/16 inches from the lane side of the foul line. If possible, check this distance, and if
different, offset the installation (including the cutout) as needed. Minor differences (no
more than ± 1 inch) do NOT require any offset. If an installation other than the standard
installation is desired, the underlane track can be lengthened or shortened as needed.
