A mine needs a lifting system – Technology Grade 8 Mini Pat Term 3 Questions and answers pdf. This mini-PAT will run over four weeks. For this mini-PAT, you should form teams. Each team will pretend to be a mechanical engineering company. Each company will submit a tender for the design and construction of a “mine-lifting system”, commonly called “mine shaft headgear”.
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.
