A system for the handling of dumpsters in side loading vehicles, which comprises a pair of holding arms associated with a structure which is configured to bring the pair of holding arms closer to the dumpster in order to pick it up and to precisely adapt the opening of the pair of holding arms which pick up the dumpster, and wherein said structure, after moving closer to the side of the vehicle, is configured to be lifted again, carrying the dumpster, until it is tipped to be unloaded in the collection truck hopper, wherein the system comprises: - a means for bringing the pair of holding arms, for holding the grasping bolts on the dumpsters, closer to the dumpster for handling; - a means for rotating the pair of holding arms and regulating the opening of the pair of holding arms for the dumpster grasping bolts; - a means for lifting the dumpster held by the pair of arms, and; - means for anchoring the dumpster grasping bolts to the pair of holding arms, and for opening the lid of the dumpsters, when they are being tipped; characterised in that the system comprises: - a 3D scanning device, comprising a laser sensor, a servomotor and a control unit, for the different types of dumpsters; - a central control unit, to which the information processed in the scanning device is sent, associated with a database for storing the different types of dumpsters according to the relative position of the grasping bolts; - a computer unit, associated with the central control unit, for interaction between the driver and the collection system; wherein the 3D scanning means is configured to: - 3D scan the dumpster in real time, by means of the laser sensor, which is coupled to the servomotor; - process, by means of the control unit, the information resulting from the scanning of the dumpster, and; - send the information resulting from the scanning of the dumpster to the central control unit; wherein the central control unit is configured to compare the information sent by the 3D scanning means, in order to determine the type of dumpster to be handled according to the relative position of the grasping bolts; and wherein, based on the detection of the type of dumpster according to the relative position of its grasping bolts, the central control unit is configured to order and control all the movements in the system; wherein the order and control of all the movements in the system comprises: - bringing the pair of holding arms closer to the dumpster, and; - regulating the opening of the pair of holding arms, each arm being regulated in an independent manner, for precisely adapting to the position of the grasping bolts. - a means for bringing the pair of holding arms, for holding the grasping bolts on the dumpsters, closer to the dumpster for handling; - a means for rotating the pair of holding arms and regulating the opening of the pair of holding arms for the dumpster grasping bolts; - a means for lifting the dumpster held by the pair of arms, and; - means for anchoring the dumpster grasping bolts to the pair of holding arms, and for opening the lid of the dumpsters, when they are being tipped; - a 3D scanning device, comprising a laser sensor, a servomotor and a control unit, for the different types of dumpsters; - a central control unit, to which the information processed in the scanning device is sent, associated with a database for storing the different types of dumpsters according to the relative position of the grasping bolts; - a computer unit, associated with the central control unit, for interaction between the driver and the collection system; - 3D scan the dumpster in real time, by means of the laser sensor, which is coupled to the servomotor; - process, by means of the control unit, the information resulting from the scanning of the dumpster, and; - send the information resulting from the scanning of the dumpster to the central control unit; - bringing the pair of holding arms closer to the dumpster, and; - regulating the opening of the pair of holding arms, each arm being regulated in an independent manner, for precisely adapting to the position of the grasping bolts.
