    Mini-pat: a mine needs a lifting system - Grade 7-9

    The lifting system is used to take miners underground and back up again. It is also used to lift the mined ore to the surface. After you have designed your lifting system, you will have to make a model of it. The model will have a mine winch, shaft headgear and a lift cage. Figure 1: This is the tower above an old mine shaft
