With reference to figures 1 to 4, with 16 is indicated as a whole a forklift truck according to the invention, which in front is provided with a cargo box block arrangement with forklift means5 , 17, 18 associated with a tipping device 15 for tipping a cargo box 12, in particular of a pallet type as typically used in the agricultural field.
For simplicity, the tipping device 15 and the elements, devices and systems different from the cargo box block arrangement being present on the forklift truck 16 are not further detailed and described as they are already known as prior art. With particular reference to figure 2, the cargo box block arrangement comprises forklift means, being constituted for example of a support plate for fork bearer 1, associable with the tipping device 15 of the forklift truck 16 through known means and in such a way that it can be rotated with respect to an axis substantially orthogonal to the same plate 1, on which are fixed fork bearer means as sliding guide, for example a pair of fork bearer crosspieces 2, 3 being shaped in such a way to constitute sliding guides for a pair of fork arms 7, 9 being shaped to the purpose.
The coupling between the fork arms 7, 9 and the fork bearer means as sliding guides 2, 3 is realized with clearance, so as to permit rotation between said arms 7, 9 and the plate 1. More in detail, each arm fork 7, 9 is in shape of a rotated L , with a lower part aimed to support and lift the cargo box 12, and an elevated part which has, externally, a pair of beak guides aimed to be inserted, with clearance, in transverse sliding on protrusions being externally shaped to the crosspieces 2, 3. Advantageously, the configuration of the forklift means as described and according to the invention allows the fork arms 7, 9 sliding on the fork bearer crosspiece 2, 3, then the fork arms 7, 9 widening which allows the cargo box block arrangement to be adapted to different width sizes, so contributing to maintain the same cargo box stable and safe when it is loaded on the fork arms of the forklift truck to be moved or tipped.
The above mentioned clearance of slide coupling between fork arms 7, 9 and fork bearer means as sliding guides 2, 3 as described, advantageously allows the fork arms 7, 9 to spread out the respective free extremities by means of spreading out means , 8, 10, 11, 17, 18 aimed to the purpose, which according to the present invention also constitute gripping means, as it will be clear hereinafter. The spreading out means , 8, 10, 11, 17, 18 are associated with the fork arms 7, 9 for the grip of the fork arms 7, 9 to the perimetral elements of the cargo box 12, in particular at the inside of the foot 13, 14 of the cargo box 12, in case of pallet box.
Such kinematic condition allows mat the force explicated by the hydraulic pistons 8, 11 is transmitted, as well as transverse thrust, as further angular torque to open the fork arms 7, 9 so as to lock, by friction, before the internal faces of the frontal feet 14 and men the inner faces of the rear feet 13 of the perimetral elements of the cargo box 12, as it will be clarified with the description of related operation. Advantageously, the spreading out means are of an exclusively mechanically operated type. This ensures greater reliability of the cargo box block arrangement as it has no electrical boxes and wiring, and therefore it is not subject to electrical failures, as well as greater simplicity of the control system and handling of the forklift truck.
A further characteristic contributes to this advantage, i. Such branch, not shown for simplicity so as the mentioned system, is associated with the spreading out means, in particular with the linear displacement actuating means, i. Hereunder, the operation of the cargo box block arrangement is detailed.

Starting from the first operating position of support of figure 3, when the control system commands the gripping of the cargo box 12 usually generates an increase of hydraulic pressure to the linear displacement actuating means, i. The hydraulic pistons 8, 11 apply a thrust force with a transverse component such as to widen laterally the fork arms 7, 9 until the fork arms come into contact with one or more internal parts of the perimetral elements of the cargo box 12, in the example primarily on the inner face of the rear feet 14 of the cargo box 12 close to it, producing a first grip strength; at the same time, due to the kinematic constraint produced by the inner surface 14 of the same rear feet, this induces a slight rotation to open the protruding extremities of the fork arms, so as to spread them out.
In fact, once prevented traverse translation, thanks to the above mentioned required kinematic condition, the thrust action of the pistons 8, 11 leads to an increase of the longitudinal component directed towards the lower part of the fork arms 7, 9, in addition to the transverse component guaranteeing the grip of the rear feet This component generates an angular torque aimed to open the fork arms 7, 9 which are able to rotate, thanks to their respective assembling with clearance on the fork bearer 2, 3; so, it is generated the opening of the lower extremities of the fork arms 7, 9 which spread out to form a large V.
Then, these extremities intercept and push on the front internal faces of the pair of front feet 13 of the cargo box 12 figure 4 , thus achieving a further grip in the front part of the cargo box 12 and simultaneously blocking all four feet 13, 14 of the cargo box The position as above mentioned corresponds to the operating gripping position of the cargo box block arrangement, according to the invention.

The cargo box 12 grip is advantageously carried out by loads being distributed on the entire perimeter of its base, i. The cargo box 12 may be further blocked by f top-down cargo box block means moving top- down and operating in pushing on one of its front wall, possibly being present in association with the tipping device 15 of the forklift truck 16 and not detailed for simplicity as already known, for example, in the same way as illustrated and described in the Italian document BAU Once you have performed eventual tipping operation of the cargo box 12, after repositioning it upright on the fork arms 7, 9, and possibly after controlling disengagement of the top-down moving cargo box block means, when present which are able to unlock on the upper part the front wall of the cargo box 12, it is possible to return to the first operating support position of the cargo box block arrangement: the control system commands the release of the cargo box 12 by generating a hydraulic pressure such in a way that the linear displacement actuating means, i.
The operation of lifting and tipping of the cargo box, thanks to this innovative cargo box block arrangement according to the invention, simply adapts to different sizes and types of cargo boxes to be lifted. In fact it is possible to lift and tip boxes of many different sizes inasmuch the excursion of the opening and then the gripping of the fork arms 7, 9 is substantially variable and adjustable thanks to the presence of the fork bearer 2, 3 shaped as transversal guides for said arms, so perfectly adapting to the lay of the perimetral elements, i.

Since the fork arms spread out in a wide V shape, they move and rotate to open and intercept the perimetral elements along the whole extension of the base perimeter of the cargo box; therefore, as in the example taken into account, they exert pressure against all the feet of the cargo box with a respective external surface thereof till blocking them, so allowing the subsequent safely ad affordable movement in tipping. Advantageously, the cargo box block arrangement according to the invention, is provided with few simple elements which ensure the functionality, convenience and low-cost thereof.

Advantageously, the transmission arms 6, 10 are reciprocally similar and essentially interchangeable, thus allowing the free use of fork arms 7, 9 of different dimensions, with no need to change the whole support plate 1, so just employing transmission arms 6, 10 of the right length and with a respective portion of extremity shaped in order to embrace the cross-section of the respective fork arm 7, 9 with their rings 17, 18; i.
Advantageously, the interchangeability of the above mentioned transmission arms and their simplicity to be disassembled, make the cargo box block arrangement and the related forklift truck more easily transportable, less bulky and easier to handle than the traditional ones. It is clear that different variations and embodiments are possible for the technician skilled in the art to the cargo box block arrangement for forklift truck with forklift means and related forklift truck according to the present invention; as it is clear that, in their practical implementation, the forms of the illustrated details may be different and be replaced with other technically equivalent elements.
He said the cargo had initially been due to include electrical transformers and that the union would check again on Wednesday.
Defense Minister Florence Parly told lawmakers she had no information on the shipment and that in any case France had a partnership with Saudi Arabia. Eurenco, an affiliate of Nexter, which produces munitions for the Caesar, did not immediately respond for comment. Rights groups have accused the French government of trying to intimidate the press and curb its freedoms. The saga is an embarrassment for President Emmanuel Macron, who has defended arms sales to Saudi Arabia and the UAE arguing the two countries are crucial allies in the fight against Islamist militants.
