Methods of positioning a protective sheet over a stack of goods comprise: engaging a lifting device to lift a first elongate member adjacent to a first side of the stack； projecting a positioning strap from a positioning strap projector, such that the positioning strap passes over a top of the stack and down a second side of the stack； securing the positioning strap and disengaging the first elongate member so that the sheet is free of the lifting device； applying tension to the positioning strap to pull the first elongate member across the top of the stack towards the second side of the stack whilst also lifting a second elongate member up the first side of the stack； and once the sheet is in place over the stack, securing the securing strap to a respective location at or near a base of the first and second sides of the stack.
