A two-loop cross-belt sorter includes at least one loop-shaped track (1); two cross-belt trolley groups (2), and forms two side-by-side conveyance loops able to circulate on the loop-shaped track (1), and a power apparatus (3) that drives the two cross-belt trolley groups (2) to move along the loop-shaped track (1). The two-loop cross-belt sorter uses two sets of trolleys on a loop-shaped track, allows the space inside the loop to be utilized and the quantity of cross-belt trolleys to be increased without increasing the area occupied by the sorter, thus doubling sorting capacity, while allowing parcels to be transferred between cross-belt trolleys on the two conveyance loops, thereby reducing the idle rate of the trolleys.

A system and an apparatus capable of independently driving movers are described herein. The system and apparatus includes: a track that forms a path for movers; a plurality of movers movably mounted on the track for moving along the path; and a plurality of drive elements fixedly arranged along the track. The drive elements each have a surface that is oriented to contact a driven member of the movers. The drive elements are configured to sequentially engage the driven member of a plurality of the movers to provide controlled independent motion of the movers along the track. The drive elements may be driven by rotary motors. A method of independently driving movers is also described herein.
