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.

Abstract: A segmental impact idler with the ability to mechanically lower idler segments is used for easy installation, removal and service of idler segments under loading skirts. The ability to mechanically lower idler segments eliminates a need to use a lifting device or to remove adjacent idlers to access the idler segments. One example of a device that can mechanically lower the segmental impact idler is a locking cam shaft. When the cam shaft is rotated, the idler can be lowered away from the conveyor belt. The idler segments can then easily slide out perpendicular to the direction of the conveyor belt without supporting the weight of the conveyor. The invention is specifically designed to operate in confined spaces. Furthermore, an adjustable mechanical linkage at one end of an idler segment, in conjunction with a pin at a second end of the idler segment, enables the idler segment to be rotatably lowered such that the idler segment can slide underneath the conveyor belt.
