When a boom truck crane operates on properly set outriggers, where is the tipping axis located?

When a boom truck crane operates on properly set outriggers, the tipping axis is located at the point where the outriggers touch the ground. This is because the outriggers serve to stabilize the crane and effectively distribute the load across a larger area, providing a solid base that prevents the crane from tipping over during operation.

The location of the tipping axis is essential to understanding how forces act on the crane when lifting loads. When the crane lifts a load, the weight creates a lever arm effect, causing the crane to want to rotate around its tipping axis. Since the outriggers create a stable platform, they significantly influence the point of balance for the crane, which is critical in preventing accidents and ensuring safe operations. Properly set outriggers enhance stability, allowing the crane to operate safely and efficiently.
