Device for moving pallets comprising a central body consisting of a first side element and a second side element, parallel one each other, and a rear element for connecting the side elements (21,22) one each other so as to delimit an empty area in between them adapted to contain a plurality of pallets stacked one above the other, wherein said central body is further provided with an opening between said side elements (21,22) on the opposite side of said rear element so as to substantially assume a U-shape, wherein said opening is able to allow the passage of at least one pallet for its/their insertion/removal into/from said empty area, wherein said device is further provided with: - at least one first shaft arranged along said first side element and at least one second shaft arranged along said second side element, said shafts (3a,3b) being both arranged towards the outside of the device with respect to said empty area; - at least one first ratchet wheel able to integrally rotate with said first shaft and a second ratchet wheel able to integrally rotate with said second shaft, wherein each of said ratchet wheels (5a, 5b) is adapted to engage/disengage with a corresponding stop tooth to support said stack of pallets or to release it to allow it to descend, wherein each of said ratchet wheels (5a, 5b) is able to integrally rotate with a corresponding first and second petal wheel, each provided with petal engagement elements and wherein the pitch between two successive petals is such as to allow one petal at a time to be inserted into a cavity laterally formed into a reference pallet characterized in that said device further comprises at least one substantially horizontally arranged lifting bar, transversely disposed with respect to said first and second side elements at said opening, and able to be constrained with said at least one first shaft at one of its first ends, and with said at least one second shaft at a second end thereof, opposite to said first end, wherein said lifting bar is able to be vertically moved downwards or upwards so as to cause the consequent rotation of each of said first and second shaft and of the corresponding ratchet wheel (5a, 5b) integral with it so that the consequent displacement of said engagement elements of said first and second petal wheels allows, respectively, the mechanical lifting or lowering of said reference pallet. wherein said device is further provided with: - at least one first shaft arranged along said first side element and at least one second shaft arranged along said second side element, said shafts (3a,3b) being both arranged towards the outside of the device with respect to said empty area; - at least one first ratchet wheel able to integrally rotate with said first shaft and a second ratchet wheel able to integrally rotate with said second shaft, wherein each of said ratchet wheels (5a, 5b) is adapted to engage/disengage with a corresponding stop tooth to support said stack of pallets or to release it to allow it to descend, - at least one first shaft arranged along said first side element and at least one second shaft arranged along said second side element, said shafts (3a,3b) being both arranged towards the outside of the device with respect to said empty area; - at least one first ratchet wheel able to integrally rotate with said first shaft and a second ratchet wheel able to integrally rotate with said second shaft, wherein each of said ratchet wheels (5a, 5b) is adapted to engage/disengage with a corresponding stop tooth to support said stack of pallets or to release it to allow it to descend, wherein each of said ratchet wheels (5a, 5b) is able to integrally rotate with a corresponding first and second petal wheel, each provided with petal engagement elements and wherein the pitch between two successive petals is such as to allow one petal at a time to be inserted into a cavity laterally formed into a reference pallet characterized in that said device further comprises at least one substantially horizontally arranged lifting bar, transversely disposed with respect to said first and second side elements at said opening, and able to be constrained with said at least one first shaft at one of its first ends, and with said at least one second shaft at a second end thereof, opposite to said first end, wherein said lifting bar is able to be vertically moved downwards or upwards so as to cause the consequent rotation of each of said first and second shaft and of the corresponding ratchet wheel (5a, 5b) integral with it so that the consequent displacement of said engagement elements of said first and second petal wheels allows, respectively, the mechanical lifting or lowering of said reference pallet.
