A lifting device for erecting a structure having splice plates is provided. The lifting device having a body adapted to engage the splice plates and having an attachment site adapted to be coupled to a hoisting apparatus. The body further has an opening defined therethrough and adapted to align with the plate openings. The lifting device also has a connection assembly comprising a support structure connected to the body and having a cradle, and a releasable connector adapted to extend through the plate openings and the opening. The cradle is adapted to secure the releasable connector through the splice plates and the body when the body is lifted via the hoisting apparatus. The connection assembly also has a disconnection mechanism operable from a ground surface to remove the releasable connector from the plate openings and the opening to disconnect the body and the structure.
E04G 21/14 - Conveying or assembling building elements
B66C 1/66 - Load-engaging elements or devices attached to lifting, lowering, or hauling gear of cranes, or adapted for connection therewith for transmitting forces to articles or groups of articles by mechanical means comprising article-engaging members of a shape complementary to that of the articles to be handled for engaging holes, recesses, or abutments on articles specially provided for facilitating handling thereof
The present invention generally relates to a modular seating riser (2) for stadia, to a set of structural modules (1) for building the same, to a kit and an assembly therefor, as well as to a method for building the same. There is provided a set (1) of structural modules for building a structurally sound modular seating riser (2) on which seats of a bleacher- type stadium can be mounted. The structural modules are an elongated metal extrusion. The set of structural module includes a first module (3) having a female tensioned catch-connector (30) provided along a lateral edge (5) thereof, and a second module (6) having a male tensioned catch-connector (28) provided along a lateral edge thereof (8). The male (28) and female (30) tensioned catch-connectors have complementary configurations for mating and interlocking together, and forming, when interlocked together, a structural permanent joint (19).
