Abstract
For handling and clamping a pipe, an apparatus includes plural clamping elements movably arranged in a device body configured as an annular shell. A positioning element is vertically movably arranged in the device body, and includes an obliquely sloping actuating surface that cooperates with a sliding surface of the clamping elements, so that a vertical or axial motion of the positioning element at least partially causes a horizontal or radial motion of the clamping elements. Also, a vertical or axial motion of the clamping elements is at least partially converted into a horizontal or radial motion thereof.
