APRON CONVEYOR TRACTION AND LOAD CARRYING RUN Russian patent published in 1998 - IPC

FIELD: mechanical engineering; continuous transportation machines. SUBSTANCE: conveyor run has covering in form of series overlapping aprons forming angular cavity in between and provided with bent opposite flanges over width, sides of covering (aprons) coupled with axles on ends of which links of outer traction chains are mounted and hinge-mounted support rolls are installed by means of bushings on axles of outer chain.
