Definitions

• This invention concerns a cargo box block arrangement for forklift truck, of a typology that employs forklift means, as well as a forklift truck provided with the related cargo box block arrangement.
• the object of the present invention is a cargo box block arrangement for forklift truck with forklift means and related forklift truck, according to the features of the enclosed claims.
• the cargo box block arrangement is of a type comprising forklift means provided with fork arms, adapted to be engaged with a cargo box for its lifting and lowering, as well as comprising gripping means associated to the forklift means for locking the cargo box to said fork arms.
• the spreading out means are of an exclusively mechanically and hydraulically operated type, in particular by applying a branch of the same operative hydraulic circuit as supplied with forklift trucks.
• FIG. 1 shows a perspective view of a forklift truck provided with a cargo box block arrangement according to the invention, during the tipping operation of a cargo box;
• FIG. 2 shows a partially exploded perspective view of a cargo box block arrangement of the invention of figure 1;
• FIGS. 3 and 4 illustrate, in bottom view, the cargo box block arrangement of figure 2 in two different operative configurations of the forklift truck of figure 1, i.e. with cargo box block arrangement respectively being disabled and enabled;
• 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.
• the spreading out means 4-6, 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.
• the above mentioned spreading out means comprise, more in detail
• - rotation locking means associated to the transmission arms 6, 10 and the fork arms 7, 9 so as to prevent the relative rotation and preferably also the relative transverse translation of each fork arm 7, 9 with respect to the corresponding transmission arm 6, 10; for example they are locking rings 17, 18 shaped as to embrace, together with an end portion of the transmission arm 6, 10, a cross section of the respective fork arm 7, 9, the rings 17, 18 being fixed each one to its corresponding transmission arm 6, 10 by fastening means, for example threaded tie rods and lock nuts, so as to allow the transmission of the transverse force and angular torque from the transmission arms 6, 10 to the fork arms 7, 9.
• fastening means for example threaded tie rods and lock nuts
• 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 14.
• 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.
