Abstract
A tensioner for the controlled clamping and moving of an elongated body (A), in particular for an installation for laying pipelines, umbilicals or cables, includes a frame carrying at least two guiding boxes (3) that are arranged about an axis of symmetry (4), for clamping a segment of the elongated body (A). The guiding boxes (3) according to the invention are mounted mobile on their support frame through operating elements (5) including: (i) at least one linear actuator (5) including an operating cylinder extended by spring element, which operating cylinder and which spring element each have a longitudinal extension axis, the extension axes being oriented coaxially, or at least approximately coaxially, relative to each other, so as to form together the extension axis of the linear actuator; and (ii) programmable elements for controlling the operating cylinder in extension.
