Abstract
A repositionable power wrench includes a housing, a motor arranged inside the housing, and an output shaft, which is rotationally connected to the motor and telescopically arranged with respect to the housing to allow axial movement of the output shaft with respect to the housing between a fully extended position (Emax) and a fully compressed position, with a resilient member being arranged to urge the output shaft towards the fully extended position (Emax). The power wrench also includes or is connectable to a positioning system arranged to monitor a position of the power wrench. The output shaft includes an output end arranged to interact with a fastener. A sensor is arranged to monitor a level of extension (E) of the output shaft with respect to the housing, such that the position of the output end of the output shaft may be determined.
