Gantry design for imaging

I am about to undertake the multi-spectral imaging of two very large
paintings on hide.  The larger of the two pieces is approximately 4
feet x 18 feet.  It will be imaged flat on a table surface.

I am designing a travelling gantry to carry the camera and light
package.  This gantry will travel in all three axes: x, y, and z.
If I can make this work using modified commercial equipment the
travel in all three axes will be numerically controlled via
computer.  I believe this to be necessary due to the width of the
painting making impossible to have manual access and control of the
camera/light package and especially so for focussing.

I am looking for input from those who have undertaken similar
projects.  And yes I proceed with some trepidation but proceed I
must.
