What does the crane's leverage depend on primarily?

The crane's leverage primarily depends on the weight of the crane and the distance from the tipping axis. This concept is rooted in the principle of leverage, which states that to lift a load safely, a balance must be maintained between the weight of the load and the counteracting forces, which typically include the crane's weight and its design.

The tipping axis refers to the point around which the crane could tip over if overloaded. The farther the center of the load is from this axis, the greater the leverage effect, increasing the risk of tipping unless adequately balanced by the crane's weight and design considerations. This relationship emphasizes why load configurations and crane specifications must be carefully calculated to ensure safe operation.

In contrast, the hydraulic system pressure, visibility of the load, and age of the crane play important operational roles but do not fundamentally determine the mechanical leverage used in lifting. Hydraulic pressure contributes to lifting power, visibility aids in safety and maneuvering during operations, and age may indicate maintenance needs but does not directly correlate with leverage mechanics.
