What should crane operators know about ground bearing pressure?
Ground bearing pressure is the force per unit area that a crane's outriggers or tracks exert on the ground, critical for preventing soil failure and crane tipping.
Ground bearing pressure determines whether the soil can safely support a crane's weight plus its load. Operators must know the ground bearing capacity (measured in PSF or kPa) and ensure the crane's ground pressure doesn't exceed this limit. Exceeding ground bearing capacity causes settlement, tilting, or complete structural failure.
Remember: "GROUND GIVES" - Ground bearing pressure Gives way if exceeds Ground capacity, causing Instability and Vessel (crane) Emergency Situation
