Tower Crane Foundation Design Calculation Example Link -

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.

Designing a tower crane foundation requires balancing geotechnical capacity, structural strength, and anchor bolt detailing. The above (with a 6m × 6m pad for a 4,500 kNm moment) demonstrates the fundamental checks:

The design of a tower crane foundation focuses on ensuring stability against overturning, bearing capacity, and structural integrity under extreme load combinations

Brands like Liebherr , Potain , and Terex often include a "Foundation" section in their technical manuals that provides the specific reaction forces needed for your calculations. Safety and Compliance The foundation acts as a counterweight

This example summarizes a typical gravity-base calculation for a medium-sized tower crane. 1.

Stability Checks

We estimate the dimensions based on a rule of thumb: The foundation weight should be roughly 1.5 to 2 times the vertical load to provide stability. The above (with a 6m × 6m pad
