Abstract
A mine shaft conveyance system includes a linear motor having spaced, parallel, elongate winding support members carrying stator windings. The winding support members are mountable in a mine shaft so as to extend in the longitudinal direction of the mine shaft. A reaction member is located between the winding support members so as to be driven up and down the mine shaft by electromagnetic forces. The reaction member is flexible about at least one axis transverse to the length of the winding support members. A shaft conveyance which is to be driven up and down the mine shaft is attached to the winding support members.
