The problem of creating a compact device for tensioning prestressing strands used for strengthening the surface of workings in mines is considered. It is proposed to use a lever mechanism with a variable structure for providing movement in several degrees of freedom. The geometrical parameters of the mechanism for obtaining the required displacements and forces are determined. The design of the device allows its use by one executive without involvement of hydraulic or electric drives.
