Clamping device

Lifting device for the stepwise displacement of a load along one or several supports, comprising two intercoupled clamping devices, each with at least two clamping members which are provided with teeth on the gripping faces and each of which, via a pressure area placed at an angle with respect to the gripping face and an intermediate member abutting the former, cooperates with a pressure member capable of exerting a clamping force directed toward the gripping face, the intermediate member consisting of a slide member having a cross section in the form of a segment of a circle whose plane surface cooperates with the pressure area and whose circular arc-shaped surface is positioned in a corresponding seating provided in the associated clamping or pressure member.

Anchoring device for anchoring a support post connected to a supporting structure, in particular on island platform to a number of piles driven into the bottom, comprising a number of clamping devices, each, with at least two clamping members which are provided with teeth on the gripping faces and each of which, via a pressure area placed at an angle with respect to the gripping face and an intermediate member abutting the former, cooperating with a pressure member capable of exerting a clamping force directed toward the gripping face, the intermediate member consisting of a slide member having a cross section in the form of a segment of a circle whose plane surface cooperates with the pressure area, and whose circular arc-shaped surface is positioned in a corresponding seating provided in the associated clamping or pressure member, while in each clamping device a pair of two interspaced clamping members cooperate with one pressure member having, on the side facing the clamping members, two pressure faces including an obtuse angle.
