摘要
A fluid operated torque tool tightens a nut (1) through a spring washer (3) on a plate (3) on a railroad crossing, and has a housing, two coaxial drives (5,6) applying equal turning forces in opposite directions around an axis, with one of the two coaxial drives (6) located around the other (5) of the two coaxial drives, a first socket (9) attached to the one coaxial drive (6) and configured to fit on the rectangular plate (3), and a second socket (10) attached to the other coaxial drive (5) inside the first socket (9) and configured to fit on the nut (1), with the washer (2) being not engaged by the sockets, so as to tighten the nut and to tighten up the spring washer onto the plate while the first socket and the housing stand still.
