  "abstract": "A roller-and-rail cargo handling system that includes tracked rollers and side rails for receiving cargo pallets. A trolley system is used to move the pallets along the tracked rollers, which includes a trolley movable along a trolley track by one or more cables. The trolley includes (1) a body sized and configured for sliding beneath the pallet located on the tracked rollers, and (2) a pawl in a cavity of the body which is mounted for rotation between closed and open positions. In the open position the pawl extends above an upper surface of the body to engage a cutout of a pallet and exert a moving force thereto, and in the closed position the pawl is sufficiently within the cavity to permit the trolley to slide beneath the pallet without engagement thereof.",
