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. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000001589 Published 2026-09-15T19:06:51.649586Z https://opentechnical.org/p/OT-2026-000001589
