MULTI-BEAM LIFTING DEVICE PROVIDED WITH CLAMPING UNIT USING GRAVITY AND MULTI-BEAM LIFTING SYSTEM
摘要
<p>A multi-beam lifting device provided with clamping units using gravity, comprises: a pair of base frames disposed to be spaced apart from each other and connected to each other; a plurality of clamping units connected to both side end areas of the pair of base frames for supporting an object to be lifted; and at least two hinge rotary bars provided at the pair of base frames which allows for a hinge movement so that the hinge rotary bars control the mutual distance of the clamping units among the plurality of clamping units, which face each other and are apart from each other.</p>
