An apparatus for wrapping a load carried on a floor-mounted pallet. The apparatus includes a carriage having a wheeled base for rolling movement about the pallet-carried load. The carriage is provded with an upright upstanding from the base and vertically movably supporting a carrier for a roll of wrapping sheet material. A handle structure is provided on the carriage for manipulation of the carriage in effecting the rolling movement about the pallet-carried load and mechanism is provided adjacent the handle for effecting vertical movement of the carrier to permit spiral wrapping of the sheet material about the pallet-carried load. The carrier is arranged to extend downwardly to a lowermost position, permitting wrapping of the pallet substantially at floor level and, in an uppermost position, for wrapping the uppermost portion of the load. The invention further includes improved structure for releasably retaining the sheet material roll on a spindle on the carrier.
