FIELD: mining.
SUBSTANCE: compensator comprises additional spherical surface for cooperation with the eccentric screw through the balls and adjusting nut. The screw passes through the opening in the traverse with a spaced relation that is equal to the eccentricity of the screw. The crank pivot is made of a bushing with eccentric opening for the cooperation, from the one side, with the eccentric screw through the collar, balls, and, from the other side, with the rod through the spherical space made in the coupling clutch and spherical groove made in the cantilever and connected with the bushing via balls and collars.
