The investigation involves both a computer model, which differs from other models in incorporating some flexibility into the conveyance, and field measurements. It is the first time to our knowledge that measurements of conveyance wheel loads and accelerations have been made in a wide range of different shafts. The results of the computer model and the measurements are analysed to give an assessment of the magnitude of the forces and of those variables which have a major influence on the forces.enThesis
