ABSTRACT:
Coupling apparatus for facilitating disengaging sling-like elongated flexible members from the load of lumber pieces being cradled therein. The apparatus includes a pair of hooks which are selectively driven between normal and couple/uncouple positions. A pair of sling-eyes are attached to one of the respective ends of the elongated flexible members and the sling-eyes are adapted for respective cooperative engagement and disengagement with the pair of hooks. Each flexible member passes through a sling-guide which operatively engages the sling-eye or presents it to the hook for recoupling as the flexible member is almost completely taken up by a winch. Subsequently, the hooks are moved to the normal position and the flexible members are sufficiently slackened for reloading.
