Which of the following is essential to verify before lifting a load with an overhead crane?

Verifying the load's weight, dimensions, and center of gravity is essential before lifting with an overhead crane because each aspect plays a critical role in ensuring a safe and successful lift.

Knowing the load's weight is crucial because it helps determine if the crane can safely lift the load without exceeding its rated capacity. If a crane is overloaded, it can become unstable, leading to potential accidents or equipment failure.

Understanding the load's dimensions is also important, as the crane must have enough clearance and the proper reach to lift and maneuver the load without obstruction. The load's dimensions determine whether there is sufficient space to operate safely and whether the lifting equipment is compatible with the size of the load.

The load's center of gravity is another vital factor. Knowing where the center of gravity is located ensures that the load remains balanced during the lift. An unbalanced load can cause the crane to tip or swing unexpectedly, increasing the risk of accidents and injuries.

Therefore, assessing all these factors—weight, dimensions, and center of gravity—prior to lifting helps operators make informed decisions and execute lifts in a safe manner. Each element is interconnected and contributes to maintaining safety standards while operating overhead cranes.
