The invention also relates to a lifting system for lifting or lowering pipe length (3, 4) and pipe-string (2), for joining and lowering or lifting and disassembling of conductor, casing, risers, drill string, or similar in a bore hole (160) or well (160). The lifting system comprises a lifting tool with a lifting part (20) and a support part (5) connected to an elevator apparatus (70) which is mounted to a top drive (60) and where the lifting tool lifting part (20) shall operate in conjunction with a power slip (150) which is configured to receive and hold in a fixed position a standing pipe length or pipe-string (2). Finally the invention comprises a method for lifting of pipe length for joining of pipe length (3, 4) to a pipe-string (2), including conductor, casing, risers, or similar for use in a bore hole or well (160) with the use of a lifting system and lifting tool according to the invention.
