Abstract
Disclosed is a method and apparatus for extracting large form panels used in forming floor slabs on poured-in-place, multi-story concrete structures from beneath the slab they last formed. The preferred embodiment apparatus, called a panel picker, includes a frame held by a crane above and adjacent to the last formed slab; the frame is anchored to the slab and contains hoists on movable trolleys for attaching to and lifting the form panel. The movement of the trolleys permits attachment to the panel picker to be made in two steps and without the panel being unsupportedly cantilevered out to where a crane could attach directly to the panel.
