Never deviate from the crane’s technical manual requirements for base reactions. 🚀 Benefits of Using Xls for Crane Foundations
: Foundation design requires professional engineering expertise . Never rely solely on an unverified spreadsheet for construction without a signature from a licensed Professional Engineer (PE).
A tower crane experiences sudden load release (snatch loading). Your XLS must include a dynamic amplification factor (typically 1.25 to 1.5). If your sheet uses only static loads, you are under-designing.
