What is the role of counterweights on a lattice boom crane?

Counterweights on a lattice boom crane play a crucial role in ensuring stability and safety during lifting operations. Their primary function is to balance the load that the crane is lifting. When the crane lifts a heavy load, it creates a moment around the pivot point, which can lead to tipping if not properly counteracted. The addition of counterweights counterbalances this moment, effectively lowering the center of gravity of the crane and providing the necessary stability to prevent it from tipping over while the crane is operational.

Counterweights are strategically placed to offset the weight of the load being lifted, which is especially important when working with larger and heavier items that can easily cause an imbalance. This design consideration is crucial for maintaining safety standards and operational efficiency in lifting operations.

While other options mentioned might seem plausible, they do not reflect the primary design purpose of counterweights in cranes.
