<p>Self-loading device for the bale-loading trailer consists of a side (8) which is made up of a beam (8a) to which are fixed four, vertical uprights (8b). The side (8) has also two arms (8c) of C-shaped cross-section on each side of the beam (8a). Into the arms (8c) fit a series of rollers (11) mounted on pivot-pins rigidly fixed to a frame (12) attached to the loader chassis. The wall (8) is moved by double-acting hydraulic cylinder (13) fixed to the frame, with its piston rod hinged at a point (14) on a transverse beam (8a). The hydraulic cylinder (13) is operated by a servo-valve spool fixed to the frame (12), with control device (16) which is operated by a stop-mechanism (17) fixed to a longitudinal support (8d) on the side (8).</p> |
