What condition must be met to ensure effective load handling with a crane?

For effective load handling with a crane, having the load directly under the boom tip is vital for maintaining balance and control during lifting operations. When the load is positioned beneath the boom tip, the center of gravity is aligned, reducing the risk of tipping or swinging. This alignment allows for more precise movements and enables the crane to handle the load with maximum stability.

If the load is not positioned correctly, it can lead to dangerous situations such as the crane tipping over, or the load swinging uncontrollably, which can cause accidents or damage to nearby structures or personnel. Therefore, ensuring the load is directly beneath the boom tip is a critical practice for safe and effective crane operation.

Other conditions, such as flat terrain, operator experience, and clear weather, may certainly contribute to safe crane operation, but they do not directly influence load handling effectiveness in the same way that the load's position does.
