What is the effect of moving the tipping axis closer to the crane's center of gravity?

Moving the tipping axis closer to the crane's center of gravity serves to reduce the stability of the crane. When the tipping axis shifts toward the center of gravity, the leverage point for any loads being lifted shortens, potentially causing the crane to be more susceptible to tipping over. Stability in cranes is primarily determined by the distance between the center of gravity and the tipping axis; a greater distance provides more leverage and stability. Conversely, when the tipping axis is moved closer to the center of gravity, this distance decreases, leading to a greater risk of losing balance and tipping. It's crucial for operators to understand these dynamics to ensure safe lifting practices and maintain the crane's stability during operation.
