A system for releasably securing a platform in a raised position is disclosed. A track is provided. An arm is connected at a first end to the platform. A second end, with a lug, is biased toward a side portion of the track. The lug is configured to ride in the track. As the platform is raised, the lug rides upward and enters the top portion and clears a first vertical wall, whereupon the lug rests in the depression and thus supports the platform in the raised position. As the platform is raised further, the lug clears a second vertical wall, whereupon the lug can ride downward in the side portion and through a bottom portion, past a door and out an open end of the bottom portion.

A clamp and universal wedge clamp system is provided. The system includes a rigid clamp that is formed to define first and second arms that extend from opposite ends of a central member. The first and second arms each comprise a finger that extends inwardly toward the finger extending inwardly from the opposite arm, and at least one of the first and second arms comprising a slot defined through the arm along a portion of a length of the arm. A wedge extends through the slot, wherein the clamp and the wedge are collectively configured to removably retain a beam upon either one of a substantially cylindrical shoring post, or a substantially rectangular shoring post.

This publication relates to a tubular transom in particular for temporary structures, such as scaffolding or false work and similar structure, having ends configured to be connected to verticals at node sections arranged at intervals on the verticals. Each end of the transom comprises a fastening device with an integrated profile part, releasably attached to the tubular transom in an opening at the ends of the tubular transom. The transom comprises a first and at least second elongate, parallel and hollow tube elements, interconnected at least at each end by intermediate integrated web plates, rigidly fixed to said at least two tube elements. A contact surface of the opening in the first tube, is transversally arranged relative to one or more web plates. A contact surface of the opening in the second tube is transversally arranged relative to one or more web plates. The opening at the ends of the transom having at least partly a complimentary shape.
