What is the maximum tripping speed for a 100 fpm elevator car?

In the context of elevator safety standards, the maximum tripping speed refers to the maximum speed at which an elevator car must be equipped to automatically stop in the event of a malfunction, thereby preventing accidents or further unsafe conditions. For a standard 100 feet per minute (fpm) elevator car, the maximum tripping speed is commonly defined to be 175 fpm.

This specification is derived from safety codes that require elevators to have sufficient stopping capability to manage unforeseen events. The selection of 175 fpm as the maximum tripping speed ensures that the elevator can effectively respond to various potential issues that may arise while in operation, maintaining safety standards and protecting passengers. Understanding this speed is essential for compliance with regulations and ensuring the overall functionality and safety of elevator systems in the Los Angeles area and beyond. Other figures proposed in the other choices exceed what is generally considered safe for a standard 100 fpm elevator, which could lead to increased risks if the system is unable to effectively stop at those speeds.
