Abstract
The invention relates to a rotating construction laser (), in particular a self-compensating construction laser. The construction laser () comprises a base () and a laser unit () for emitting a laser beam () rotating around an axis () of rotation so that the rotating laser beam () defines a laser plane. Therein, the laser unit () is built and tiltably arranged to the base () in such a way, that the axis () is tiltable in at least one direction. Furthermore, a tilt sensor () is present for measuring the tilt of the axis (). According to the invention, the tilt sensor () is supported by a sensor platform being pivotable with respect to the laser unit around the axis () between at least two defined pivoting-positions (-) in such a way, that the tilt of the axis () is measurable by the tilt sensor () in the at least two pivoting-positions (-).
