What is the maximum amount of static door force allowed to hold a door in the open position?

The maximum amount of static door force allowed to hold a door in the open position is 30 foot pounds. This limit is established to ensure that the door can withstand external forces without compromising safety or functionality. The specific value is derived from industry standards that take into account the balance between allowing for ease of use and preventing unintentional door closure, which could pose a risk to passengers or equipment.

By setting a maximum of 30 foot pounds, regulations help to ensure that doors remain securely open when needed, while also allowing for a manageable force that can be applied without causing damage or injury. Understanding this limit is crucial for those working with elevator systems, as it directly relates to the safety and reliability of door operations.
