• the present invention relates to a collection truck for emptying the waste collection bins, comprising a collection bucket and mechanical emptying means for taking a tank presented dump and make it follow a complete emptying movement, from the moment said tray is lifted from the ground until it is rested on the ground, passing through the moment when the tray is reversed to empty into the bucket, said truck being characterized in that it comprises at least one configurable member among the mechanical emptying means, said member being capable of following at least two modes of operation distinguished by at least one parameter determining the kinematics and / or the dynamics of the mechanical emptying means during the emptying movement of a complete tank.
• the invention makes it possible to implement bin emptying operations reducing the noise emissions caused by the truck itself and by the sound interactions, of shock or vibration types, occurring between each tank and the truck during emptying, precisely adapting the trajectory of the tank, its orientation, its speed and its acceleration at every moment, so as to make the emptying operation as quiet as possible.
• the parameters determining trajectory, orientation, speed and acceleration of the tank during its emptying were determined according to the desired efficiency of the emptying and, especially, to ensure the emptying of all types of tanks likely to be emptied by the collection truck.
• some parameters were necessarily over-dimensioned with respect to certain tanks and some inappropriate trajectories, at least with regard to the noise generated, notably because fast and brutal movements were often retained as providing the best average efficiency of emptying against several types of bins.
• the truck comprises a manual means of selecting between several emptying modes, each emptying mode corresponding to a different parameter setting of the configurable body of the mechanical emptying means.
• This embodiment has the advantage of being very simple to execute: the person responsible for presenting bins to the truck for emptying selects a dump mode before triggering the dump.
• the modes of emptying proposed can depend on the type of tank or more simply of a choice between "rapidity”, “economy of energy” and “silence”. This choice can be made by the operator according to the time he has and the environment in which the emptying takes place. Another possible choice, compatible with the previous one, is "normal cycle” or "very dirty cycle”, depending on what the operator can observe the contents of the tray.
