Have you ever wondered why cranes carry massive blocks of weight behind them? These counterweights may look like extra material, but they play a crucial role in helping cranes lift enormous loads while maintaining stability. In this video, we explore the engineering and physics behind crane counterweights. We’ll explain how moments and torque work, why the position of a counterweight matters, how it affects a crane’s center of gravity, and why adding more weight does not automatically increase lifting capacity. We’ll also look at how different types of cranes use counterweights in different ways.
