FIELD: mining industry.
SUBSTANCE: invention relates to mine machinery. Proposed jack has cylinder connected with longwall conveyor, rod, piston and guard casing. According to invention, one of converter windings, being field one, is secured, coaxially to piston rod, to end face of cylinder between rod and wall of guard casing. Other winding, being measuring one, is mounted on inner surface of cylindrical part of casing, being distributed along path of cylinder movement.
EFFECT: simplified design of system of longwall conveyor moving jack-displacement converter.
