What is Pythagoras’ Theorem? We’re glad you asked! Pythagoras’ Theorem, also called the Pythagorean Theorem, is a geometry formula discovered by the ancient Greek mathematician Pythagoras sometime between 569 – 475 BC. The theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other […]

The Effect of Angles on Sling Capacities The effect of sling angles on sling capacity refers to how tension increases on each sling leg as the sling angle decreases from vertical. When sling angles become smaller, each sling leg must carry more force, which reduces the safe working capacity of the sling. Using slings at […]

One of the most commonly used pieces of lifting equipment is the hand chain hoist, also known as a chain fall. Notable for their versatile use in various industries, modern hand chain hoists have maintained their durability and ruggedness while minimizing pulling effort, so the operator doesn’t need to overstrain. However, that doesn’t mean they […]

Shackles come in many types and may be used in various rigging and load securement applications. However, as with all equipment, certain guidelines must be followed to ensure lifting shackle safety during operations! What are lifting shackles? Lifting shackles are metal, U-shaped components commonly used in lifting operations. They serve as a secure connector between […]

Save Money and Time by Avoiding These Rigging Mistakes Rigging and lifting heavy loads is a necessary part of construction. As such, rigging is commonplace across multiple industries. Experienced riggers make lifting operations look easy, but the reality is far from it. Common rigging mistakes can be lethal, but are also avoidable. You may be […]

Having a qualified rigger on site during a lift isn’t just a best practice—it’s a requirement under OSHA and ASME standards. Whether you’re using a crane on a major construction site or in a tree-trimming application, updated guidelines now mandate the presence of a qualified rigger in far more scenarios than before. If you’re responsible […]

5 Rigging Safety Rules Rigging is a common operation on many job sites, but it’s also a dangerous business if not done right. At LGH, we take safety seriously, and we hope you do too. That’s why we’ve devoted this blog post to rigging safety. This won’t cover everything you need to know about rigging, […]

When it comes to rigging hardware, is one choice greater than another? In what situations are shackles not the right option? If your only readily available lifting beam would place angular forces on the lifting point, are eye bolts viable? In selecting hardware for your lift, the project or lift plan tend to dictate the […]

As one of the most used pieces of portable rigging equipment, gantries would be one of the most misused pieces of equipment. Here are seven horrible mistakes made using aluminum gantries.
