A cableway cabin, having supporting elements including a base frame, a roof frame and at least four corner columns connecting the base frame to the roof frame. All these parts are formed only from tubular sections having a circular inner cross-section. The parts are which has three connecting pieces, at least one of which is conical and one of which in each case is pressed into one of the three tubular sections forming a corner. Unless all three connecting pieces are conical, it is expedient to make the non-conical connecting piece or connecting pieces cylindrical and to provide them with a constriction extending over more than 60% of their length and filled with a resilient adhesive.
