ABSTRACT:
For trowelling concrete spread over a floor, a trowelling device is used, which includes a carrier having a cantilever arm swingable over the floor. At the distal end of the arm a rotatable trowelling member is carried in a pedestal structure permitting vertical adjustment of the floor contacting parts. A laser sends a horizontal beam at a predetermined level over the floor, and an upwardly directed measuring rod at the housing of the trowelling member is provided with a detector for catching the beam, and for transferring deviations of the beam from a mark thereon into signals for adjusting the position of the trowelling member.
