The invention relates to a system for supporting a pipe string ( 2 ) to which an additional pipe element has to be connected, comprising a lifting device ( 1 ), a wedge device ( 3 ) and an abutment element ( 4 ). The invention also relates to a lifting device ( 1 ) comprising an attachment foundation ( 10 ), a lifting arm ( 11 ), which is in linked connection with the attachment foundation ( 10 ) and a replaceable tension element ( 14 ) in the form of a circular are connected to the lifting arm, where the wedge device ( 3 ) is releasable secured to the tension element ( 14 ), thus enabling the wedge device ( 3 ) to be moved by means of the lifting device ( 1 ) from an inoperative position in a position above the abutment element ( 4 ) to an operative position where the wedge device ( 3 ) abuts against the abutment element ( 4 ), thus securing the pipe string ( 2 ) by means of the wedge effect. The invention also relates to a method.
