Sling, n.
"A device for securing or grasping bulky or heavy articles while being hoisted or lowered, usually a belt, rope, or chain formed into a loop and fitted with hooks and tackle (cf. quots. 1627, 1769); a loop of this kind by which heavy objects are lifted, carried, or suspended." More complex than the slingshot that took down Goliath.
