In
this post you said the assembly weighs 28 pounds.
In
this post you said that the center of mass of this 28 pound assembly changes from 31" to 57".
That's a change of 26".
To change the center of mass of a 28 pound assembly from 31" to 57" requires 28*(26/12) foot-pounds of work. This is true regardless of whether you are lifting the entire 28 pound assembly 26", or lifting half the 28 pound assembly 52", or anything in-between.
