Crane Stability and Ground Pressure Guideline HSSE WORLD

Then the pressure imposed by the crane to the ground can be calculated by: Force = 48 tonnes x 9.8m/s2 = 470.4 kN. Area of the crane mat = 1.7m x 1.7m = 2.89 m2. Pressu re = 470.4 kN/2.89 m2= 162.8 kN/m2. If the maximum permissible ground pressure is 200kPa, then the crane mat size is adequate for the lift. Example 2.
