- a movable element also called in the following description, hammer 24, articulated on the two vertical walls of the rod 20 by an axis 25, so as to occupy a retracted position along the the rod (as shown in Figure 2B), or a position substantially perpendicular to the rod (as shown in Figure 2A).
- the hammer 24 has a substantially parallelepiped shape.
- this hemispherical portion rests in a hemispherical housing 260 arranged in a seat 26 housed in the lower part of the rod 20.
- actuating and locking means in particular comprising a jack 27, enable the hammer 24 to be moved from one position to the other and to hold it there.
- the hammer has an axis 25 guided in sliding along the rod 20, inside a groove 23.
- the groove 23 is not rectilinear but follows a path adapted to allow the positioning of the part hemispherical 242 in the housing 260 of the seat 26.
- the dimensions of the element 2 are such that the height of the rod 20 is greater than or equal to the height of the reservations 10, the outer dimensions of the rod 20 (and the hammer 24 retracted along thereof) is smaller than the dimensions of the bookings 10.
- the length of the hammer 24 in the deployed position is greater than the dimensions of the bookings 10.
- the hammer 24 further comprises, on its face intended to come into contact with the voussoir, two flats 240 and 241 for the support on the concrete.
- the clearance between the rod 20 and the reservations 10 is adapted to allow the voussoir to be oriented according to the desired angles of inclination and slope.
- the various components of the element 2 are made of steel or any other suitable material.

- a centralizing computer allows the use of several Spica sensors to obtain a position X, Y and according to a given rotation of the object positioned below the sensors.
- These sensors are designed for the detection of containers or steel coils below the gripping tool of a gantry unloading, they are robust, shockproof and waterproof.
- the voussoir will present for this purpose for example 11 markings detectable by the sensors, such as reflective paint strips.
- the sensor beam 32 is schematized by a hatched triangle.
- a man-machine interface allows the operator of the rudder to visualize the position of the rudder relative to the markings, which allows him to move it to a correct position.
- any other suitable means such as a CCD camera, can be used.
- one or more webcams are used arranged on the device so as to target the reservations associated with the lifting rods and connected to the man-machine interface by any appropriate means, thus allowing the insertion of each stem in the corresponding reservation.
- the device may also include an ultrasonic distance sensor.
- the communication between the centralizing computer and the man-machine interface is preferably carried out by means of radio modems.
- the device according to the invention has the advantage of avoiding the use of metal inserts, while remaining compatible with standard lifting means. Moreover, the cinematic attachment of the voussoir is particularly simple and free from human intervention.
- the handling elements are reusable from one voussoir to another and it is sufficient, on a site, a limited number of elements.
- four elements are sufficient to ensure the handling of all the voussoirs of the site, while with the conventional device including metal inserts, four inserts by voussoirs were necessary.
- any other type of heavy structure for the construction such as Accropode TM blocks, which are concrete structures arranged at the seaside for protect the banks of the waves.
