1. A loading system (LS) for an optical machine, having a carrier (TR), which is movable in a movement plane (x-y) by way of two linear guide units (LF1, LF2) and which carries at least one holder (H1, H2, H3) for an optical workpiece (L) and/or a block piece (B) and/or a tool, the holder being movable in a transverse direction (z) with respect to the movement plane (x-y), wherein the linear guide units (LF1, LF2) are constructed and arranged in the form of an H gantry or a cross gantry, with two stationary drive motors (AM1, AM2) for drive in the same or opposite sense of a traction element (ZG) which is movably arranged in an H shape or a cross shape at the linear guide units (LF1, LF2) and secured to the carrier (TR); and wherein one linear guide unit (LF1) comprises two stationary x guide elements (XF1, XF2), which extend parallel to one another and at each of which a respective x half-carriage (HS1, HS2) is guided to be longitudinally displaceable, while the other linear guide unit (LF2) comprises two y guide elements (YF1, YF2), which extend parallel to one another and transversely to the x guide elements (XF1, XF2) and rigidly connect the x half-carriages (HS1, HS2) together and at which the carrier (TR) as y carriage is guided to be longitudinally displaceable.
