What is the primary function of additional counterweights on a crane?

The primary function of additional counterweights on a crane is to maintain balance and stability. When a crane lifts a load, the weight of the load creates a moment or torque that can cause the crane to tip over. Counterweights are strategically added to the opposite side of the crane's boom to counteract this torque, ensuring that the center of gravity remains within the crane's stable operating range. This design enhances safety by preventing the crane from tipping and allows for heavier loads to be lifted without compromising operational integrity.

The presence of counterweights is crucial in maintaining the stability of the crane during operation. By effectively balancing the load, the counterweights allow cranes to perform more complex lifting tasks while minimizing risks.
