■ Tie-Off Options for Loading
and Unloading Materials
When steel erection contractors receive materials for laydown yards at job sites, often personnel must work from an elevated location on the trailer. Tie-off regulations vary by industry for loading and unloading. The X500 is a new Free-Standing Anchor from Malta Dynamics, Malta, Ohio, that provides an overhead fall protection anchor point for up to five workers that can be positioned where needed. Part of the XSERIES Mobile Grabber product line, the X500 has a 360-degree rotatable arm with a 20 ft. high overhead anchor point. The X500 can be towed to the job site. Field assembly is simple with bolt-together components. Other features include leveling jacks and forklift pockets.

■ ArcReach Offers Field Solution for Weld Preheating
and Bakeout
Miller Electric, Appleton, Wis., introduces the ArcReach Heating System, which is designed for jobsite weld preheating and bakeout in construction and pipe applications. The system delivers temperature maximums of 600° F/315° C. This induction heating system is faster, safer and less expensive than open-flame or resistance methods. ArcReach Heating Systems use electricity from heating tools placed on or around magnetic metal surfaces, such as iron or steel, to create currents in the metal. Induction results in temperatures that are consistent and evenly controlled throughout the weld, which can save hours and hundreds of dollars per weld joint. ArcReach Heating System
■ TNA® Fastening System Receives RCSC Approval LeJeune Bolt Company, Burnsville, Minn., announced the approval and inclusion of their TNA Fastening System in the 2020 Edition of the Research Council on Structural Connections (RCSC) Specification for Structural Joints Using High-Strength Bolts. Users can now specify ASTM F3148 TNA® bolts and the RCSC combined method on future projects. The Combined Method uses torque for the snug tightening process and then employs angle (degree of nut rotation) for final tensioning. The method is the first to establish a minimum snug tight tension, and LeJeune’s Torque + Angle Fastening System is the first system on the market to utilize the combined method. 12 | THE STEEL ERECTORS ASSOCIATION OF AMERICA
