During platform installation, the platform stops if obstructed by how many pounds of force?

• A. 5 lbs
• B. 50 lbs
• C. 15 lbs
• D. 100 lbs

Answer: (C)

Safety devices on the platform monitor the force opposing its movement and are set to stop the drive when an obstruction pushes back with a relatively small amount of force. In this case, about fifteen pounds of external resistance is enough to trigger an immediate stop. This keeps hands, tools, or clothing from being dragged and protects the equipment from damage, while still avoiding nuisance stops from minor, everyday contacts. If the threshold were much lower, like a few pounds, normal handling could cause frequent, unnecessary stops. If it were much higher, the platform could continue moving despite a real obstruction, increasing the risk of injury or damage. So fifteen pounds strikes the right balance for safe, predictable stopping during installation and testing.
