ABSTRACT:
A belt support system for supporting a belt member along a portion thereof during a material transfer operation where a flow of material is allowed to impact the belt member at a predetermined impact location, the present system including a plurality of roller members housed in three separate members which are positioned in side-by-side relationship to each other, the center member being secured to a support structure and the two opposed end or wing members being each pivotally mounted to the center member and to the support structure so as to be angularly adjustable relative to the center member. The pivotal adjustability of the three members allows the present system to be positionable so as to conform to the particular configuration of the belt member to be supported such as a cradle or containment channel configuration typically formed by many bulk conveyor belt transfer systems, and use of the roller members substantially reduces friction between the support system and the conveyor belt moving thereacross at the impact location. Use of the present system helps to alleviate the forces and stresses applied to the belt member at the impact location; it stabilizes the belt member at the impact location to substantially reduce material spillage and fugitive dust emissions; and it increases the overall longevity of the belt member and other conveyor components.
