Abstract
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.
