Patent attributes
A bolt tensioning tool is adapted to tension a bolt protruding from a workpiece, and includes a bolt receiving element adapted to be screwed onto the bolt, a nut socket adapted to receive a nut, an axle adapted to exert an axial force on the bolt receiving element, a threaded sleeve arranged to engage the axle and having an internal thread adapted to cooperate with an external thread of the axle such that a relative rotational movement therebetween results in a relative axial displacement between the axle and the threaded sleeve, a supporting sleeve coupled to the threaded sleeve and adapted to selectively bear against the workpiece, and a coupling adapted to connect the nut socket and the supporting sleeve, the coupling is a coupling allowing a limited relative movement between the socket and the sleeve.
