The garland idler set comprises either 3-roll or 5-roll idlers joined together at the ends of their respective shafts by special lugs, to form a continuous 'chain' of idlers. On either end of this 'chain', the shafts are connected to an attachment bracket which enables the idler set to be attached to the conveyor stringer structure. The garland idler design is more forgiving than the fixed-base troughing idler, due to its chain-like design which allows the belt centerline and idler centers to move relative to the supporting frame.
Garland idlers are used predominantly on yard conveyors, shiftable conveyors, and dump conveyors, etc. where the alignment of the conveyor structure may not be completely correct due to the mobility of the conveyor, or the ground conditions onto which the conveyor structure in founded.
