A drop sling lumber sorter apparatus (20) comprising a frame assembly (22) i ncluding a plurality of bays (24) for receiving pieces of sorted lumber (L). Each of the bays (24) includes a rotatable drive shaf t (62) mounted to the frame assembly (22) and a pluralit y of elongated, flexible, laterally spaced slings (50) having a first end and a s econd end. The first end of each sling (50) is mounted to the drive shaft (62). A pivoting hook (98) and retriever assembly (100) selecti vely capture and release the second end of each sling (5 0) to the frame assembly (22). A spool assembly (60) is mounted on the drive shaft (6 2) for each sling (50). Each spool assembly (60) is cap able of guiding the sling (50) onto the rotatable drive shaft (62). The slings ( 50) are reeled onto or reeled off of the drive shaft (62 ) as the drive shaft rotates. A tensioner assembly (130) tensions the slings (50) as they are reeled off of the drive shaft (62).
