Question: 1 / 400

What is the function of counterweights in a tower crane?

To assist with emergency stops

To increase the lift capacity of the crane

To balance the load being lifted and prevent tipping

Counterweights in a tower crane serve a vital function in ensuring stability during operations. Their primary role is to balance the load being lifted. When a load is raised by the crane, it creates a force that can potentially tip the crane over, especially if the load is heavy or if it is extended far from the center of the crane's base. By distributing weight effectively, the counterweights counteract this tipping force, maintaining the center of gravity and allowing the crane to operate safely without risking overturning.

This balance is crucial in scenarios where the crane is lifting loads near its maximum capacity or extending its boom to reach outwards. The strategic placement of counterweights enhances the overall stability of the crane system, making it an essential feature for safe lifting operations in construction and other industries.
