Climbing systems, kits, assemblies, components, and methods for reducing construction accidents

A climbing assembly configured for extension between an underside of a structural floor decking of a building and a supporting floor of the building, the assembly comprising:

• a telescopic climbing structure having an upper end and a lower end defining an axial dimension of the structure, the structure configured for extension between the supporting floor and the structural floor decking, with the lower end configured to contact the supporting floor and the upper end configured to engage with a portion of the structural floor decking, with the structure including at least three nested members, and each of the nested members having a set of two or more climbing-rung through holes and a corresponding set of two or more climbing rungs configured to extend therethrough and thereby fix a corresponding position of each climbing rung along the axial dimension of the climbing structure;
• means, including a horizontal late and at least one vertical structure configured to extend into the structural floor decking a predetermined depth, for restricting lateral movement of the upper end of the climbing structure relative to the decking, wherein the means for restricting lateral movement further includes a retaining-collar attached to the horizontal plate, and the one vertical structure includes a pin or a fastener;
• means, associated with the climbing structure, for establishing and adjusting a compression force between the upper end of the of the climbing structure and the structural floor decking, wherein the means for establishing and adjusting the compression force includes a jack;
• and
• an OSHA-compliant fall-protection tie-off attached to the climbing structure and configured to couple with a worker safety harness.
