Abstract

The invention relates to a slipform paver having a chassis 2 able to be adjusted in the heightwise direction and having a mounting unit 10 arranged on the chassis for fastening on an arrangement 8 for molding flowable material. The slipform paver according to the invention is characterised in that the mounting unit 10 for fastening on the concrete mold 8 is mounted on the chassis 2 of the paver to be pivotable on an axis 14 extending in the direction of operation of the slipform paver. To produce parts of a structure whose orientation varies along their length, the concrete mold fastened 8 to the mounting unit is pivoted on the axis of pivot 14 by means of a pivoter unit 15 whereas the chassis of the paver maintains its orientation.
