What is a load chart?

Answer 1

A load chart....is a chart usually found on the arm of a crane. It shows you how much the machine is rated to lift at specific points of the lift under ideal conditions. In equipment with telescopic booms; the weights that it can lift varies ( the further you have to extend; the less weight it can bear), as well as turning radius under load also varies. The more you turn your crane under load the less stable your crane can become causing it to topple over if you don't abide by the chart and try to lift more then it's rated capacity. Although a load chart is the most important chart you must understand before operating a piece of machinery such as this, it does not take into account other factors that can effect a load such as; wind speed, condition of the equipment, how to rig or sling a load, or any other deciding human factor. Take a crane course before messing with this kind of equipment. Learn how to read a load chart properly. your life is worth more then the equipment that could topple over and kill you.
