Which factor does NOT affect crane stability during operation?

During crane operations, stability is influenced by various factors that primarily relate to physical conditions and equipment integrity. Worker experience is important because it affects how well the operator manages the crane and responds to different situations, but it does not directly alter the crane's mechanical stability.

Weather conditions can affect crane operations by influencing wind speed, rain, and visibility, which can make the crane less stable if not accounted for. Equipment maintenance is crucial; if a crane is not properly maintained, it can suffer from mechanical failures that compromise its stability. Load distribution is a fundamental aspect of crane operation, as improper load distribution can lead to tipping or imbalance, making it a direct concern for stability.

Thus, while experienced operators play a significant role in safely operating the crane, the factors that directly alter the crane’s physical ability to remain stable are related to environmental influences, equipment conditions, and how loads are managed and distributed.
