To understand a load chart, you must understand the physics of leverage. A crane acts as a first-class lever. crane load charts
📍 Always leave a safety buffer. Many expert operators aim to keep lifts under 75-80% of the rated capacity to account for unexpected gusts or minor measurement errors. Use the onboard angle indicator or a manual measurement
$$ \text{Net Capacity} = \text{Gross Capacity} - \text{Rigging Weight} $$ crane load charts
The capacity of the crane is determined by the . As the load moves further away from the center (increasing the "Radius"), the leverage (moment) increases exponentially. To prevent the crane from tipping over, the load weight must decrease as the radius increases.
