What is the primary purpose of counterweights in cranes?

To increase operational speed

To balance the load being lifted

The primary purpose of counterweights in cranes is to balance the load being lifted. This is crucial for maintaining the stability of the crane while it is in operation. When a load is lifted, it creates a moment that can cause the crane to tip over if not properly balanced. Counterweights serve to counteract this moment by providing an equal and opposite force, enabling the crane to lift heavy loads safely without risking its stability.

By distributing weight appropriately, counterweights help ensure that the center of gravity remains within safe limits, allowing for smoother operations and reducing the likelihood of accidents due to tipping or excessive strain on the crane’s components. This balance is essential not only for safety but also for effective and efficient lifting operations.
