What is the maximum allowable closing force of a passenger elevator according to ASME elevator code?

The maximum allowable closing force of a passenger elevator, as specified by the ASME A17.1 elevator code, is set at 30 pounds. This limit is established to ensure the safety and accessibility of elevator doors. It is important that the closing force is not excessively strong to prevent the risk of injury to passengers, particularly vulnerable individuals such as the elderly or those with disabilities who may inadvertently get caught as the doors close. The force limit is specifically designed to provide a balance between effective closing mechanisms and user safety, ensuring that doors close securely without posing danger during their operation. This regulation is part of a broader set of safety guidelines that govern elevator design and operation.
