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.

Abstract: For holding a pipe, rod or the like, such as a section of a pipe string of an offshore oil drilling rig, an apparatus includes a clamping device insertable into a support body. The clamping device includes a device body with a central opening bounded by an inner circumferential surface that conically tapers at a cone angle. The device further includes clamp elements that are received in the central opening of the device body and that each have a radially outer surface sloping along the cone angle to slide along the inner circumferential surface of the device body, and a radially inner clamping surface to clamp against the coaxially arranged pipe. A holding element respectively connects each clamp element to a linear actuator stroke element that is similarly tilted at the cone angle. The linear actuator may be received in a receiver shaft of the device body.
