1. A storage and retrieval unit comprising:
a carriage that is displaceable along a linear guide arranged on a floor in a shelf aisle in a direction of an X axis, the carriage supporting a vertical mast that extends substantially perpendicular to the X axis in a direction of a vertical Y axis; and
a load receiver mounted by only one end on a support device, the load receiver being adapted to be moved vertically together with the support device along the mast and adapted to be moved into and out of a shelf compartment in a direction of a Z axis that runs substantially perpendicular to the X axis and substantially perpendicular to the Y axis,
wherein the load receiver is adapted to be pivoted about a pivot axis running substantially parallel to the X axis such that the load receiver is brought into a position inclined downward towards the floor, in which position a front free end of the load receiver that is remote from the support device is arranged lower than a rearward end of the load receiver that is close to the support device,
wherein the support device together with the load receiver is displaceable along a transverse guide in the direction of the Z axis and is pivotable about the pivot axis,
wherein the transverse guide is formed on a guide part that is pivotable on the carriage about the pivot axis running substantially parallel to the X axis, and
wherein a pivoting movement of the guide part about the pivot axis in a direction of the vertical Y axis is superimposed with a lifting or lowering movement, and a displacement movement of the support device and of the load receiver along the transverse guide is superimposed, via a controller, such that the load receiver is adapted to be moved along an at least partially curved path of movement from an inclined position within the shelf aisle into a horizontal receiving position below an object to be retrieved when the load receiver is moved into the shelf compartment.
