Static tipping load is defined as which of the following?

• A. The theoretical maximum stable load at a given height and center.
• B. The actual safe load under dynamic conditions.
• C. The load carried by the bucket when empty.
• D. The dynamic tipping load when stationary.

Answer: (A)

Static tipping load is the theoretical maximum stable load a wheel loader can lift at a specific height and center of gravity, determined under static conditions with no movement or dynamic forces. It represents the stability limit based on the machine’s geometry and the combined center of gravity of the machine and its load at that reach, assuming the surface is even and everything is momentarily still. This differs from loads that consider movement, acceleration, or rough terrain, which can reduce what’s safely liftable in real operation. The other options describe conditions that aren’t the static stability limit: a safe load under dynamic conditions involves movement and timing; the empty bucket scenario isn’t about stability of a loaded lift; and a dynamic tipping load when stationary mixes terms that don’t apply to the static, non-moving case.
