Adding counterweight to a crane primarily affects which aspect?

Adding counterweight to a crane primarily enhances the stability of the crane. When lifting heavy loads, the center of gravity shifts, which can create a tipping hazard if not properly managed. Counterweights are used to balance the crane against the load being lifted, ensuring that the structure remains stable and minimizing the risk of overturning.

A well-balanced crane can operate safely, allowing it to lift loads more effectively and with greater confidence. Stability is crucial when working with cranes, especially in environments where they might be subjected to varying wind conditions or uneven terrain.

In contrast, while counterweights play a role in ensuring that the crane can lift its specified load without tipping over, they do not significantly change the height of the crane, the distance of its operational range, or its overall load capacity, making stability the primary aspect affected by the addition of counterweights.
