发明名称 Fall restraint anchoring post
摘要 An apparatus for use in fall restraint anchoring of workers on an elevated location includes an upstanding post with at least one attachment loop at an upper end. The post is formed by plurality of coaxial cylindrical tubes each mounted as a sliding fit inside the next with each insert tube having a longitudinal groove co-operating with a projecting set screw on the outer tube so as to prevent relative rotation and to locate the limits of movement for aligning holes in the tubes for a locking pin. A jib portion includes a collar located on the smallest tube with a lower edge sitting on the upper edge of the next tube and extends upwardly and outwardly to a tether which extends to the attachment loop.
