Dual-function, sequential-task, lug-registry, pick and stack-align building-component handling system

摘要: A system for handling various structural building components including a pick and stack-registry lug which is anchorable to the top of component that in either one, or both sequentially, its two, functional modes, (b) clamshell-style, releasably lockable clasp adapted receive close capturingly upon under operational circumstances with anchored component, ready function category component-handling behavior, (c) guide socket includable base camming, guided reception then functioning mode behavior facilitate overhead stack registering two relation lowering an onto underlying whose also has it.
