What load placement technique can help prevent crane tipping?

Placing loads close to the crane's base center is the most effective technique for preventing crane tipping. This practice helps maintain the crane's center of gravity and enhances stability during operations. When the load is positioned closer to the base, it minimizes the leverage effect that can cause the crane to become unbalanced or tip over. A low center of gravity is crucial for safe lifting, as it keeps the crane steadier and reduces the risk of accidents.

In contrast, placing loads far from the crane's center can increase the chance of tipping because this action raises the center of gravity and creates a greater moment arm. Similarly, using longer load slings might introduce unnecessary sway or instability to the load during lifting, while lifting loads quickly can lead to loss of control and increase the risk of an accident. Each of these alternatives fails to effectively maintain the crane's stability, reinforcing the importance of secure load placement close to the crane's base for safety in crane operation.
