The extendable arms attached to a crane base that relieve the wheels of crane weight and provide stability are referred to as outriggers. Outriggers extend from the main body of the crane and are crucial for distributing the load and enhancing stability during lifting operations. By spreading outward, they create a broader base of support, which helps to prevent tipping or toppling of the crane, especially when it is lifting heavy loads or working on uneven ground.

In crane operations, stability is paramount to ensure safety and efficiency. The design of outriggers allows the crane to safely operate at greater heights and reach without compromising structural integrity. Their use is essential for maintaining balance, especially when working near the upper limits of a crane's lifting capacity. In contrast, other options like stabilizers, counterweights, and supports serve different roles within crane operations, such as managing load shifts or enhancing the stability of stationary equipment. However, it is the outriggers that specifically provide this critical support by extending and anchoring the crane to the ground.
