When you see two different excavator brands claiming a “rated lift capacity of 5,000 lbs at 15 ft reach,” SAE J1397 ensures those numbers are apples-to-apples. The standard dictates the same load point height (typically 1.5 meters or 5 feet above ground), the same bucket configuration, and the same stability margin.
