What should be considered when hoisting loads in windy conditions?

1. Hoist heavier loads

2. Use a shorter boom extension

3. Reduce load height

4. Anchor crane with extra weight

The correct answer is: Reduce load height

When hoisting loads in windy conditions, reducing load height is crucial for maintaining stability and safety. Lowering the load minimizes the crane's exposure to wind, which can exert considerable force on the load and destabilize the crane itself. A lower load is less susceptible to being swayed by gusts, which can affect both the crane's balance and the safety of the operation. This practice helps prevent potential accidents such as the load swinging uncontrollably or the crane tipping over. In contrast, other options may not address the risks associated with wind. For instance, hoisting heavier loads would increase the stress on the crane and make it more difficult to control the load in windy conditions. Using a shorter boom extension might seem beneficial, but it does not necessarily mitigate the effects of wind on the load being lifted. Lastly, anchoring the crane with extra weight could potentially add risk by affecting the crane's center of gravity and stability if not done correctly. Thus, focusing on reducing the height of the load during windy conditions is the most effective approach to ensure safety and operational stability.
