Adjustable Spreader Bar Safety Tips & Load Calculations
Planning a complicated lift? Using a spreader beam (aka spreader bar) can help you distribute weight evenly, reduce stress on slings, and improve load stability, but only if you calculate forces correctly and follow safe rigging practices. In this video, LGH’s Aaron Orsak explains adjustable spreader beam stress calculations and shares best practices for safe, efficient lifting. You’ll learn how to calculate sling tension, account for sling angles, and prevent overloads on your shackles, slings, and beams. In this video, you’ll discover: The difference between a spreader beam and a lifting beam How to calculate sling tension with and without sling angle effects Why sling angles under 30° can be unsafe How to use the Load Angle Factor (LAF) or Tension Factor (TF) to determine safe working loads How to prevent equipment failure by verifying working load limits and balancing your beam Recommended sling angles (45°–60°) for most lifts Whether you’re lifting in construction, manufacturing, offshore, or industrial settings, understanding spreader beam stress calculations is critical for safe, reliable lifting operations. 📍 Location: LGH USA 🌐 Get expert lifting & rigging advice: https://www.rentlgh.com 📞 Contact LGH USA: +1-800.878.7305 LGH: Your Partner for Safe, Reliable Heavy Duty Lifting & Rigging Equipment
