ABSTRACT:
Prior known enclosed conveyors have had a conventional belt conveyor mounted on a structural framework resting on a series of support columns known in the art as bents. A housing or gallery, as it is known in the art, consisting of a roof, side walls and optionally a floor, is constructed on structural members around the conveyor covered by a protective material. Often times, the housing is large enough to accomodate a walk-way alongside the conveyor. In each instance, however, both the housing and the conveyor are supported by structural members and not by the protective covering material of the housing. There have been instances of short spans of enclosed conveyors using solid longitudinal members as side and top walls as well as for support, but these spans have no internal stabilizing members to prevent undesirable distortion of the conveyor housing.
