A driving device includes a frame, a screw-nut system comprising a threaded rod and a first nut helicoidally connected to the threaded rod, the threaded rod being connected to the frame by a pivot connection that allows the threaded rod to rotate with respect to the frame about a longitudinal axis of the threaded rod, a first position sensor making it possible to detect a limit position of the first nut along the longitudinal axis, the first position sensor comprising a first part and a second part, the first position sensor being sensitive to a variation in a distance between the first part and the second part of the first position sensor along the axis, the first part being fixed to the first nut and the second part being connected to the threaded rod without passing via the pivot connection and in such a way that rotation of the threaded rod about the longitudinal axis leads to a variation in the distance between the first part and the second part of the first position sensor along the longitudinal axis.

Driving device

A drive device includes a screw-and-nut system comprising a threaded rod and a first nut that is connected to the threaded rod by means of a screw connection; a gearset, allowing a rotational movement to be transmitted to the threaded rod, a first toothed wheel and a second toothed wheel engaged with the first toothed wheel; a set of stops comprising a first stop connected to the first wheel rotating about an axis of rotation of the first wheel and a second stop connected to the second toothed wheel rotating about an axis of rotation of the second wheel, the first stop and the second stop being configured and arranged to butt against one another so as to limit an angular travel of the threaded rod at a first angular position in a first direction.

A strapping device for binding an object which has a cross section having a regular-shaped perimeter, the device includes a strap having a clamping strip which forms a loop intended to surround the object, the clamping strip has a central part which has a shape essentially following the shape of the perimeter of the cross section of the object and two strip strands having the respective ends of the clamping strip, the shape of which departs from the shape of the perimeter of the cross section of the object, the strap having at least one so-called central shoe which is mounted on at least one of the strip strands in such a way as to be designed to be interposed between the object and the strip strand.

Strapping device

A device for handling and towing a submersible object includes a tilting structure with a support, to pivot about a first axis parallel to a horizontal plane, and equipped with a guide device, a pivot connection about a second axis in a plane substantially perpendicular to the first axis, to allow a rotary part of the tilting structure to rotate relative to the support, the rotary part having the guide device, a stabilizing device to keep the rotary part in a deployed position relative to the support provided a torque of the relative pivoting between the rotary part and support about the second axis does not exceed a predetermined threshold, to allow the rotary part, equipped with the guide device, to rotate relative to the support about the second axis once a torque of relative pivoting between the rotary part and support about the second exceeds the threshold.
