Abstract (en)
[origin: WO2012177234A1] A remote chute rotation assembly may include a chute, a cable system and a control head. The chute may direct ejected material based on an orientation of the chute. The control head may be operatively coupled to the chute via the cable system. The control head may enable remote adjustment of the orientation of the chute via the cable system. The orientation of the chute may be adjustable through a plurality of positions fixable by a positioning assembly disposed at the chute.
