The tipping load is the hook load at a specified radius about a line called the tipping fulcrum, which causes the crane to tip. The crane rating is based on taking a percentage of the tipping load. In the United States and Canada, the ASME crane load rating is 75 percent for crawlers and 85 percent for truck cranes of the tipping load. In other industrial countries the crane load rating is 66.67 percent and 75 percent, respectively. A crane will tip when the overturning moment (moment of the load and boom about the tipping fulcrum) becomes close to equal to the crane resisting moment (moment of the machine weight about the tipping fulcrum).

A stability test is conducted for truck and hydraulic cranes when the machine is in a state of balance about its tipping fulcrum. At this condition, the entire weight of the machine and load is being supported on two outriggers
