ABSTRACT:
A tool for tightening and untightening screwed devices, such as bolts for fixing engines (10) to struts (12) on aircraft, comprises a hydraulic wrench (20), a hydraulic pump (22), preferably manual, at a distance from the wrench, and a tube (24) connecting the pump (22) to the wrench (20). The tool also comprises a force resistance structure (26) that transmits wrench reaction forces to an adjacent part, such as the strut (12).
