Tower Crane Foundation Design Calculation Example Link
The primary objective is to ensure stability against Overturning (OT) , Sliding (Shear) , and Bearing Capacity failure . The foundation must be heavy enough and large enough so that the crane does not tip over, even in the worst-case wind loading scenario.

Scenario: A crane requires a foundation on soil with an allowable bearing capacity of
The foundation acts as a counterweight. Its primary job is to ensure that the combined center of gravity of the crane, the load, and the foundation remains safely within the foundation's "kern" (the middle third of the base) to prevent overturning and minimize ground bearing pressure.
Assume 4 anchor bolts, each M48 grade 8.8. Tensile force per bolt due to overturning = (M / lever arm) / 2.

If you take one thing away from this post, let it be this: In India, perfection is overrated. It is the imperfect , chaotic, human moment that matters most.
