According to spacing chart B, what is the distance from the face of the structure to the center line of the crane?

The distance from the face of the structure to the center line of the crane, as indicated in spacing chart B, is critical for establishing the proper operation zone for tower cranes. Correctly identifying this distance ensures that the crane can operate safely without interfering with the structure. In this context, a distance of 10'10" from the face of the structure to the center line of the crane is particularly important because it allows adequate clearance for the boom swing and for the safe handling of materials around the structure.

This specification helps in minimizing the risk of accidents and ensures compliance with safety regulations that dictate how close equipment can be operated near buildings. Understanding this distance not only relates to safety but also to effective crane operation, enabling operators to maximize efficiency while maintaining safety protocols. This dimension is often derived from structural engineering standards and the specific design of the tower crane being used.
