摘要： A method for controlling a screwdriver that has an electromotor, the electromotor having a clear ratio of rotational speed (n) to torque (M) at a defined effective voltage (Ueff soll), involving the following method step: —defining an effective voltage (Ueff soll) for operating the electromotor, —defining a cut-off rotational speed (nab) that corresponds to a pre-defined cut-off torque (Msoll) at the pre-defined effective voltage (Ueff soll), —operating the screwdriver under load with the pre-defined effective voltage (Ueff soll), —during operation of the screwdriver: —determining the rotational speed (n), —shutting down the electromotor when the cut-off rotational speed (nab) is attained.

摘要： The screw tensioning device comprises a support tube (12), a cylinder member (15) and a piston section (17). The piston section serves for moving a tensioning bolt (20) screwed onto the thread of a threaded bolt (31). Provided according to the invention is a depth measuring device (35), which presents an externally visible indication of the screw-in depth (ET) of the threaded bolt (31). This ensures that, when the threaded bolt (31) undergoes extension under strain, there is a threaded engagement with the tensioning bolt (20) along a sufficiently long distance. This avoids the hazard that the screw tensioning device might break off from the threaded bolt.

摘要： A securing system for power wrenches, for immobilizing a power wrench, which is placed on a threaded bolt with a nut, in an axial direction of the threaded bolt is provided. The securing system includes a securing device. The securing device includes a locking element which engages with a threaded section of the threaded bolt projecting over the nut, the locking element being movable in a radial direction relative to the threaded bolt to engage with the threaded section of the threaded bolt.
