Abrégé

A handheld bending device for bending or straightening a power cable comprises a drive tool having a housing including a gripping handle, a bending guide including an arcuate guide surface having a predefined bending radius, an arm having a proximal end which is rotatably mounted to the bending guide and rotatable with respect to the bending guide about a first axis of rotation which extends in transverse direction of a bending plane and a distal end which has a supporting surface that faces the guide surface within a predefined mutual angle of the arm and the bending guide and a cable holder which is mounted to the bending guide and has a cable holder surface opposite to the guide surface under operating conditions. The guide surface, the cable holder surface and the supporting surface lie within the bending plane. The drive tool is a separate drive tool which has an output drive shaft including a second axis of rotation, which is releasably and drivably connected to the proximal end of the arm such that the first axis of rotation coincides with the second axis of rotation.

Device (10, 20, 30) and method for tightening a bolt (2) or a nut (12) threaded on its end, which end extends through at least a first body (3) and screws into a hole (5) in a second body (4) or extends through the second body into another nut (13). The device has gripping means (7, 17) co-acting with the bolt-head or the nuts. Means (8) process a signal generated by sensor means (18) subject to the axial force exerted on the surface of the first body by the bolt-head or the first nut, or on the surface of the second body by the second nut, and control the device such that the bolt-head or a nut is tightened subject to the axial force exerted on the surface- of one of the bodies, which sensor means are in an annular body (16) around the threaded hole between the bolt-head or first nut and the first body or between the second nut and second body.
