A method for removing a concrete panel from a form, where a lifting pressure is applied to the lower side edge of the concrete panel (1) by means of a lifting frame (7, 8) suspended in a crane hook (2). The concrete panel (1) is removed from the form (3) in a mainly vertical position by means of a cantilever foot or feet (5), and is steadied against the frame by a claw on a swivel arm (6). Since the panel is lifted from the bottom, rather than being pulled from the top, the concrete does not need a great tensile strength, and the hardening time is reduced, as the compressive strength of newly poured concrete is considerably greater than the tensile strength. <IMAGE> |
