A method of positioning a protective sheet to cover a stack of goods having first and second opposing sides and a top surface, (a) the protective sheet comprising first and second opposing parallel sides, each side comprising an attached first and second rigid elongate member extending substantially the entire length of each respective parallel side of the sheet, each rigid elongate member having attached at least one securing strap and at least one positioning strap, with (b) a lifting device comprising a support for mounting the first rigid elongate member in a substantially horizontal orientation, the support comprising at least one positioning strap projector； the method involving the steps of: (1) engaging the lifting device to lift the first rigid elongate member adjacent to a first side of the stack of goods, while the first rigid elongate member remains substantially horizontal, wherein the at least one positioning strap attached to the first rigid elongate member being lifted is loaded into a respective at least one positioning strap projector, until the first rigid elongate member is positioned above the top surface of the stack of goods； (2) projecting the at least one positioning strap from the at least one positioning strap projector, such that the at least one positioning strap passes over the top of the stack and down the second side of the stack； (3) securing the at least one positioning strap and disengaging the first elongate rigid member from the support so that the sheet is free of the lifting device； (4) applying tension to the at least one positioning strap so as to pull the first elongate rigid member across the top surface of the stack of goods towards the second side of the stack of goods whilst also lifting the second elongate rigid member up the first side of the stack of goods； (5) once the sheet is in place over the top surface of the stack of goods, securing the at least one securing strap depending from both the first and second rigid
