What is the slope of the front and rear stability of the counterweight balanced stacker in the base-load operation state?

The slope of the front and rear stability of a counterweight balanced stacker during base-load operation is critical for ensuring that the machine can operate safely without tipping over while carrying loads. The correct choice, which indicates a stability slope of 18%, reflects the design specifications and safety standards that are typical for such equipment.

A slope of 18% suggests that the counterweight balanced stacker has been engineered to maintain stability under normal operating conditions, offering a balanced center of gravity when lifting loads. This means that when the stacker is in operation with a typical load, the chance of tipping is minimized as long as the load is within the specified limits.

Higher stability slopes, such as the 20% option, would indicate even a more robust stability characteristic, often found in heavy-duty equipment or special applications, while lower slopes like those of 10% or 15% might not provide adequate stability for safe operations with regular loads. Therefore, choosing 18% is based on both operational efficiency and safety, aligning with standard practices in forklift design and operational guidelines.
