A conveyor belt idler assembly comprises support structure, a strand of catenary idler rollers, and an outboard wing roller or slider bar. The strand of catenary idler rollers can take on various trough-shaped contours. The outboard wing roller or slider bar is attached to the support structure and is able to translate relative to the support structure only along a linear path. The translational movement of the outboard wing roller or slider bar along the linear path is at least partial dependent upon changes in the contour of the strand of catenary idler rollers. The structure is adjustable such that the strand of catenary idler rollers can be lowered and raised to facilitate servicing and installation. A plurality of idler assemblies can be connected to each other using connecting brackets that rigidly tie the assemblies to each other near the outermost idler rollers or slider bars.
