If a stacker is running at an initial speed of 20 km/h with no load, how far should it stop according to safety regulations?

The correct distance for a stacker to stop according to safety regulations, when running at an initial speed of 20 km/h with no load, is 5 meters. This requirement is rooted in safety protocols aimed at ensuring operators have adequate stopping distance in various conditions to prevent accidents and ensure pedestrian safety.

The distance is calculated based on several factors, including the operating speed, the type of braking system of the stacker, and the reaction time of the operator. At a speed of 20 km/h, the stopping distance is manageable, allowing for 5 meters to effectively reach a complete stop without risking the safety of individuals in the vicinity or damaging equipment.

This stopping distance is considered appropriate based on industry standards for maneuverability in tight spaces and the need for reaction time in emergency situations. Longer distances, such as the other options, may imply unnecessary delays in stopping or reduced efficiency in operations, while shorter distances may compromise safety. Therefore, 5 meters represents a balanced approach between operational efficiency and safety compliance.
