): The total weight of the crane structure, counterweights, and maximum rated lifting capacity. Horizontal Load (
): The rotational force trying to tip the crane over, which he saw could reach as high as 4,000–5,000 kNm. Primarily from wind pressure against the mast. The Core Challenge: Stability against Overturning
Applying this to the example:
Wf=B×L×D×γccap W sub f equals cap B cross cap L cross cap D cross gamma sub c
Volume=5.5×5.5×1.3=39.325 m3Volume equals 5.5 cross 5.5 cross 1.3 equals 39.325 m cubed
Manufacturers provide service loads (unfactored characteristic loads). For this example, consider a 36 m high tower crane with a 70 m boom:

Caused by wind, braking, or eccentric loading. 2. Tower Crane Foundation Design Calculation Example
A standard foundation design typically involves a reinforced concrete pad or a pile-supported cap. The design process must account for:
The stability of the foundation must be checked to ensure that it can resist overturning and sliding.
Crane is operating with maximum lifted load and maximum allowable working wind speed.
The pressure exerted on the ground must not exceed the safe allowable bearing capacity ( qallq sub a l l end-sub
Substituting the values given above:
