ABSTRACT:
A support for a conveyor belt is provided. The support has a series of frames that may be installed beneath the underside of the conveyor belt to support the underside of the belt in a trough-shaped arrangement. Each frame supports a guide element, such as a roller, slider bar or bearing block, that permits the belt to ride over the frames. The frames may be installed beneath the belt and removed from beneath the belt from one side of the conveyor belt. Installation and removal of the components require minimal side clearance beneath the belt. As a result, the support may be installed and removed with minimal interference from adjacent structures or fixtures beneath the belt.
