摘要： A load lifting apparatus suitable for use in a materials-handling operation, which enables loads of various shapes and structures, e.g. concrete products, to be clamped by a one-touch simple operation despite an extremely simple structure and allows the loads to be released by a one-touch simple operation at desired places after they have been lifted and moved thereto. The apparatus includes a link mechanism (14) in which a pair of clamping members (1 and 2) and a plurality of members (4, 5, 8, 8-1, 8-2) are supported by a plurality of pivot shafts. The upper part of the link mechanism (14) is arranged to be capable of being lifted and lowered by a lifting device. The clamping members (1 and 2) rotate about a pivot shaft (3 or 3') in response to vertical extension and contraction of the link mechanism (4), thereby enabling an object (11) to be grasped by the distal end portions of the clamping members (1 and 2) directly or indirectly through grab members (10) by the extension of the link mechanism (14), and allowing the object (11) to be released therefrom by the contraction of the link mechanism (14). The apparatus has a lock-unlock mechanism (20, 30, 40, 50, 60, or 70) actuated in response to the vertical extension and contraction of the link mechanism (14), caused by vertical movement of the lifting device, to lock the clamping members in respective predetermined positions of rotation about the pivot shaft and to unlock the clamping members in response to the vertical movement of the lifting device.
