Why is it essential to accurately calculate load weights and dimensions before any crane operation?

Accurately calculating load weights and dimensions before any crane operation is essential for several reasons related to safety and operational efficiency. First, it ensures that the selected crane has sufficient lifting capacity for the load, preventing overloading and potential structural failure. Second, accurate dimensions are necessary to determine the required boom length and radius, ensuring that the crane can safely reach the load's final placement point without exceeding its operational limits or encountering obstructions. Third, precise weight and dimension information is critical for selecting the appropriate rigging hardware and calculating sling angles, maintaining load stability during the lift. Finally, knowing the load's weight helps to determine the ground bearing pressure, ensuring that the ground can support the crane and load without sinking or becoming unstable. For example, if the load's actual weight exceeds the crane's capacity at a given radius, the crane could tip over, causing serious injury or property damage. Ignoring accurate load calculation undermines the entire safety planning.
