ABSTRACT:
The invention relates to an arrangement in a pipe handling system, especially for handling pipes (4P) in connection with a derrick 1A, wherein the arrangement comprises a tower (1) and two preferably individually controlled operating arms (2a, 2b). The pipe handling system operates favorably in connection with a finger board (4) in which all fingers (4a, 4n) are pointing towards the center of the pipe handling system and especially towards a disc-shaped locking unit (4R) mounted on the top of the tower (1), and in connection with a side-step retraction system designed for use with a top drive drilling system.
