The object of the present invention is a device for moving a load and for the control thereof, particularly for regulating the positioning and/or orientation of a first plane, for example that is integral with an automatic machine, with respect to a reference plane or direction, for example that of the force of gravity. More specifically, the present invention consists of a device that makes it possible to move at least a number of points of the lower portion of an automatic machine and/or of the surface of an object along at least one axis (C), so as to regulate the orientation and/or inclination of the machine and/or object with respect to a reference direction.

A feeding module includes a slider and a guider. The slider includes two sliding portions, a first connecting portion and four sliding blocks with hydrostatic bearing. Each sliding portion has a first through hole. The first connecting portion is connected to the sliding portions. Two of the sliding blocks are disposed in the first through hole in one of the sliding portions, another two of the sliding blocks are disposed in the first through hole in another one of the sliding portions. Each sliding blocks has a second through hole. The guider includes two cylindrical portions corresponding to the two sliding portions. One of the cylindrical portions penetrates through the second through holes in two of the sliding blocks. Another one of the cylindrical portions penetrates through the second through holes in another two of the sliding blocks.
