In general, the load chart states the weight of the load that the crane can lift at different boom radii. The longer the radius at which the lift occurs, the smaller amount of weight the crane can lift. You must not operate a crane in excess of its rated capacity.
What affects the amount of weight a crane can lift?
For example, if the boom of the crane is extended to 250 feet and the radius (the distance from the center of the load to the center of the crane) is 180 feet, the max load weight drops considerably. The shorter the lift, the more weight can be handled. Transportation of the cranes also needs to be considered.
Can a crane lift more than its own weight?
The maximum load that the crane can lift is 18 metric tons (39,690 pounds), but the crane cannot lift that much weight if the load is positioned at the end of the jib. The closer the load is positioned to the mast, the more weight the crane can lift safely. The 300 tonne-meter rating tells you the relationship.
