The term 'jib capacity' specifically refers to the maximum load a crane can safely lift when it is utilizing its jib. A jib is an extension of a crane's boom and serves to enhance its reach. The capacity is essential for ensuring safe operations, as it dictates the upper limit of how much weight can be handled by the jib without risking structural failures or accidents.

Understanding jib capacity is crucial in crane operations, as exceeding this limit can lead to dangerous situations. The weight limitations are determined based on several factors, including the crane's design, the materials used in construction, and the expected load distribution.

In contrast, the other options focus on different aspects of a crane's operation. For example, the weight of the ballast is related to stability, the strength of the suspension system pertains to how well it can support loads and mitigate vibrations, and the total weight of the boom relates to its structural properties but not directly to the lifting capacity. Each of these factors plays a role in crane performance but does not define 'jib capacity' as directly as maximum load does.
