Abstract: The present invention provides a positioning and safety lanyard device, for use in the prevention of falls from an elevated height, comprised of: two loops or substantially looped portions, a fixed loop and an adjustable loop, the adjustable loop having a pull side with which to either, while the wire positioning and safety lanyard device is in use, shorten or lengthen the adjustable loop depending on the direction of pull; crimped, no-slide wire holders or the like; slidable wire holders or the like; a knot configuration with which the fixed loop and the adjustable loop are adjoined; and spring-loaded clasps or the like at each end of the positioning and safety lanyard device.

Abstract: The present invention provides a column climbing device for climbing structural steel columns having flanges and the like. The column climbing device includes a platform member having a toe portion and a foot portion, the toe portion of the platform member including a first interior surface and a second interior surface together defining a substantially-rectangular notch open to one side of the toe portion of the platform member, the first interior surface and the second interior surface in a fixed parallel orientation with respect to one another, wherein the substantially-rectangular notch is configured to frictionally engage a flange of a column through one or more intervening hardened plate members. The column climbing device also includes one or more attachment mechanisms attached to the foot portion of the platform member for securing the platform member to a foot of a user.
