What role do outriggers play in crane operation?

Outriggers are critical components in crane operation designed to provide stability to the crane during lifting operations. When a crane lifts a load, it creates significant forces that can cause it to tip or become unstable. Outriggers extend outward from the crane's base, distributing the weight and anchoring the crane to the ground, which helps to counterbalance the force of the load being lifted. This stability is essential for safe operation, ensuring that the center of gravity remains within a safe range.

The other options do not accurately reflect the primary function of outriggers. While they are essential for stability, they do not lift the crane off the ground, extend the reach of the crane's boom, or serve as a guide for loading. Each of these functions is handled by different systems and components within crane design and operation.
