The present invention concerns a method and system for sorting items comprising movable carriages (10) intended to transport the items, and connected to each other by a link (19), along a track having sections located at levels at different heights linked by ascending and descending slopes, a control system and drive units intended to move the carriages (10). Dedicated thrust units, separate from the drive units, are added on the slopes and are controlled individually by the control system so as to deliver a constant force in order to prevent the carriages (10) experiencing tension at the links (19, 20) as a result of the weight of the items and/or the carriages (10) present on the slopes.
Item sorting system (7) comprising movable carriages (10) intended for conveying said items (7) and connected together by a link (19, 20) along a travel route (1) having sections situated at different elevation levels connected by one or more ascent and descent slopes (P), a control system (22) and drive units (13) intended for advancing the carriages (10) and controlled by the control system (22), characterised in that it comprises at least one dedicated thrust unit (131, 241, 261) separate from the drive units (13), present on at least one of the slopes (P), and controlled in a unitary manner by the control system (22) so as to deliver a force (R) to reduce or cancel the tension or the compression to which the carriages (10) are subjected at the level of the links (19, 20) which would be due to the weight of the carriages (10) and/or of the items (7) present on said slope (P).
