A measuring position for studies of the kickback of a hydraulically-powered hand-held percussive tool

A measuring position for studies of the kickback of a hydraulically-powered hand-held percussive tool, particularly of a hammer drill, which has a unit, mounted on the frame of the position base, fitted with a dynamometric force detector and a percussive tool, cooperating with the detector, which is applied to the rock block. It is composed of a mobile support (4) sliding along the frame of the position base. A dynamometric force detector (6) is mounted on the latter indirectly, via a core (1); and the percussive tool (7) is sliding along the dynamometric force detector (6) via a console (2) sliding on the core (1) of a mobile support (4), and the percussive tool (7) is attached to the console (2); the dynamometric force detector (6) is mounted at the end of the core (1), inside the console (2) and has a contact with the percussive tool (7) via the inside wall (8) of the console (2), and the percussive tool (7) is located against the rock block (9) with the use of a hydraulic cylinder (3), via a mobile support (4).
