Question: 1 / 400

Explain the term "tip-over" in crane safety.

When a crane lowers its boom unintentionally

When a crane loses its balance and falls over, often due to improper lifting or unstable ground conditions

The term "tip-over" in crane safety refers to a situation where a crane loses its balance and falls over. This phenomenon can occur due to various factors, including improper lifting techniques, exceeding the crane's load capacity, or working on unstable or uneven ground. Maintaining the crane's center of gravity is crucial, as shifting loads or sudden movements can lead to tipping.

Inadequate setup, such as failing to use outriggers properly or setting the crane on a soft surface, can significantly increase the risk of a tip-over. Understanding this concept is essential for crane operators to prevent accidents and ensure safety on the job site. Recognizing the signs of instability and adhering to safe lifting practices are fundamental to preventing such incidents.
