Overhead Crane Practice Test 2025 – Comprehensive All-in-One Guide for Exam Success

Determining the center of gravity of a load is best achieved by balancing the load on a single point. This method involves finding the point at which the load can be suspended without tipping or falling to one side. When the load is balanced in this manner, the center of gravity is at that balancing point, as it indicates where the weight is evenly distributed around it. This is a practical approach that allows for precise identification of the center of gravity, which is crucial for safe lifting and maneuvering with an overhead crane.

Other methods, such as estimating based on previous lifts or measuring the height of the load, do not provide an accurate determination of the center of gravity. Estimations can vary significantly based on the individual characteristics of the load, while height measurements alone do not account for the distribution of weight across the load. Similarly, identifying it by color does not provide any relevant information regarding the physical properties that affect balance and weight distribution. Thus, balancing the load is the most effective and reliable method for determining its center of gravity.
