When the hatch device 4 is opened, the cargo load, the goods, falls out of the carriage 2, downwards out of the carriage 2. Wagons with unloading via an opening in the bottom of the trolley is usually used when the goods consist of a bulk load which can be emptied by free fall out from the underside of the trolley.
    The invention is mainly developed for this type of trolley but can also be used on other types of trolleys. A trolley may, for example, comprise an opening arranged at the upper side of the trolley or at a side portion of the trolley. This is not shown in the figures as the invention does not relate to the carriages themselves as these are of a previously known type. An opening placed in this way can also be provided with a door device which can be opened and closed.
    This location of the opening, and the door device, enables top emptying or side emptying of the trolley. The trolley, or a part of the trolley, for example a goods container comprising the opening, and / or the opening can suitably be changed position, rotated, rotated, tipped, so that the opening during the actual turning of the trolley is placed so that the trolley load, the goods, can fall out of the trolley , downwards out of the trolley, through the opening, just as with bottom emptying.
    The device 1 according to the invention is characterized in that it comprises at least one vibration-creating unit 5 which acts on, shakes, vibrates, the carriage 2 when the carriage device 4 of the carriage is opened, if any. The invention relates to a device 1 which can be used to vibrate, shake the carriage, so that parts of the goods are released from other goods, and also from the carriage, and this may also be desirable in other types of carriages with other locations of an opening than just at the bottom. the vibrations facilitate the unloading of the goods 10 15 20 25 30 35 P41200897ENOO 3 so that it becomes possible to obtain completely emptied and clean wagons, wagon baskets, after unloading is completed.
