FIELD: mining.
SUBSTANCE: hydraulic stretching device contains cable iron clad into dead eye, under-pulley platform, and gantry, hydraulic drive cylinder of which is installed on under-pulley platform under gantry and is fed from oil station via hydro-distributor. A wedge dead eye of the cable is assembled at the top on the gantry which is assembled on the under-pulley platform. The hydraulic drive operates step-by step; the cable is additionally drawn through a collet of the piston of the hydraulic stepped drive; the hydro-cylinder drives the cable and fixes it.
EFFECT: invention facilitates additional cable forcing and loading, also facilitates control of cable stretching by pressure value in hydro-system of hydraulic stepped drive.
