What is the purpose of a crane load chart?

The purpose of a crane load chart is to indicate the maximum capacity of the crane under every permissible configuration. This chart provides critical information regarding how much weight the crane can safely lift at various radii and boom angles, ensuring safe operations. Each crane has its unique specifications based on its design and engineering, and the load chart reflects these limits to prevent overload situations that could lead to equipment failure or accidents.

The load chart helps operators visually assess and plan lifts according to the specific conditions of the job site, ensuring that they adhere to safety regulations. Safe lifting practices are crucial in preventing accidents and ensuring the safety of personnel and equipment on-site.

While safety tips for operators are important (which could be found in training materials or operational guidelines), the load chart itself specifically conveys capacity limits rather than general safety advice. Calculating the weight of the load is a separate process that involves understanding what is being lifted, while maintaining a record of maintenance history is essential for the longevity and safety of the equipment but is not the primary function of a load chart.
