What is the purpose of counterweights in a crane?

Counterweights in a crane play a crucial role in maintaining the stability and balance of the equipment while it lifts loads. When a crane starts to lift a heavy object, there is a significant moment that can cause the crane to tip over if not properly managed. The addition of counterweights effectively supplements the weight of the load by shifting the center of gravity, ensuring that the crane remains steady and secure.

By distributing weight appropriately, counterweights help counteract the forces acting on the crane during operation, which is vital for safe lifting practices. This function is essential in preventing accidents and ensuring that the crane can operate efficiently without the risk of overturning. Hence, the design of cranes includes counterweights specifically to enhance stability when handling loads.
