<p>The chainless propulsion system of a cutter-loader for freeing the mineral comprises a guiding rack (4) which is engaged with sprockets (7) being rotatably mounted on the cutter-loader. The sprockets (7) are kinematically connected with hydraulic cylinders (9, 10) through a rotatory mechanism (11) which causes the revolving motion along the rack (5). The rotatory mechanism (11) is provided with a carrier (12) having thereon a pusher (15) which is adapted for the engagement and the disengagement with the sprocket (7). To this effect the pusher (15) is articulated on the carrier (12) kinematically connected with the hydraulic cylinders (9, 10), which are arranged opposite to the pusher (15). </p> |
