ABSTRACT OF THE DISCLOSURE A support and enclosure system for a hinged belt conveyor includes a frame truss enclosing loaded and unloaded belt flights. The frame truss includes a plurality of vertical risers. The loaded flight rides between a plurality of troughing roll sets and top idler roll sets. The unloaded flight is supported and guided by return idler roll sets. Each of the roll sets is connected distally by a clevis to mounting shafts. The mounting shafts are accepted into mounting brackets. The mounting brackets for the troughing rolls and return idler rolls include a locking bolt for fixing the position of the shafts in the bracket. The bracket for the top idler rolls includes a spring for biasing the top idler mounting shafts outward so as to bias the top idler rolls downward onto the loaded flight. Each mounting bracket incorporates a recess for accepting a first portion of a riser and a pivoting leg for engaging an opposed section of the riser. The arm and leg are biased together by a bolt which clamps the bracket to the riser. The brackets and the roll sets connected thereto are selectively positioned on the riser both vertically and rotatably by loosening the bolt, positioning the bracket, and retightening the bolt. The system also includes an orienting pulley positioned in advance of a head pulley and the tail pulley in the direction of belt travel. The orienting pulley relieves stress and prevents the twisting of the hinged belt as it travels about the head and tail pulley. The frame truss in an alternative embodiment is covered by a cap to protect the belt and its contents from the elements and to better protect to personnel from being caught in the belt.
