The lifting system lifts at least one of the sheets from the support frame. The feeding system obtains the at least one sheet from the lifting system and feeds the at least one sheet toward an installation apparatus for installation on the mine roof. The lifting system includes a shoe and at least one arm for moving the shoe to engage and move the at least one sheet. The feeding system includes a drive assembly and a support. The drive assembly engages and moves the at least one sheet toward the installation apparatus, and the support supports the at least one sheet moved by the drive assembly.
