True or False: Overloading a crane, even just once, is safe if the manufacturer includes a safety factor.
The answer is a resounding FALSE! This is one of the most dangerous myths in the lifting industry, and believing it can lead to catastrophic failure.
A "safety factor" is NOT extra capacity. Here’s the breakdown:
⚙️ It's a Buffer, Not a Bonus: A safety factor is an engineering buffer designed to handle unforeseen forces like sudden wind gusts, shock loading from abrupt stops, or slight variations in material strength. It is not a green light to exceed the crane's rated capacity chart.
⛓️ The Damage of 'Just Once': A single overload can cause 'shock loading', creating invisible micro-fractures in steel components like the boom, slew ring, or hoist rope. This permanently weakens the crane's structural integrity through metal fatigue.
💥 A Ticking Time Bomb: The damage from one overload might not be visible. The crane may seem fine, but it has been critically compromised. The next lift—even one that is well within the load limits—could be the one that triggers a complete and sudden structural collapse.
There is no such thing as a "safe" overload. The only safe lift is one that is within the manufacturer's specified load limits. Klug Avalon's LMI/SLI systems are your last line of defense, designed to prevent these situations from ever occurring.
