Patent ID: 8869411

Claim:
A rotating laser device, comprising: a laser unit, wherein a laser beam is generatable by the laser unit; a leveling device, wherein a laser beam is alignable by the leveling device in a horizontal plane which is arranged perpendicular to a gravitational field of earth and which is spanned by an X axis and a perpendicularly aligned Y axis; an inclination device, wherein a laser beam is inclinable by the inclination device about an axis of inclination in relation to the horizontal plane, wherein a laser plane generated by the laser beam is inclined in a direction of the X axis and is aligned horizontally in a direction of the Y axis; a rotational unit, wherein the laser unit is movable by the rotational unit about an axis of rotation at a rotational speed; a measuring unit, wherein an angle of rotation of the laser unit about the axis of rotation is determinable by the measuring unit; and a memory unit, wherein an angular position of the laser unit in which a direction of inclination is aligned parallel to the X axis and perpendicular to the Y axis is storable in the memory unit.
