If a machine decreases the distance an object moves it must also decrease the amount of work that is done.
Work is defined as the product of force and distance in the direction of the force (W = F * d). If the distance decreases, and work is the product of force and distance, then the amount of work done must also decrease.
The force needed to move the object may or may not change, depending on the specifics of the machine and its mechanical advantage.
