Which lifting capacity is NOT typically accounted for in the lift chart?

The lifting capacity that is not typically accounted for in the lift chart is related to "lifting over the back." The lift chart generally provides information on the maximum capacities of the excavator based on different configurations and operating conditions. This chart primarily focuses on the hydraulically-limited and stability-limited capacities, which are critical for ensuring safe operation under various scenarios.

When lifting over the back, the center of gravity of the load shifts, impacting stability in a different manner than when lifting in other positions. The configurations for safe lifting generally emphasize operations over the front and sides. Lifting mechanisms and positions that compromise the excavator's stability, like lifting directly over the back, could lead to tipping or loss of control, which is why this specific scenario is often addressed more cautiously outside of standard lift charts.
