NEIEP Mechanics Practice Exam

How often and with what load should governors be tested?

1. Every year with half rated load

2. Every 5 years with rated load at rated car speed in the upward direction

3. Every 5 years with rated load at rated car speed in the down direction

4. Every month with minimal load

The correct answer is: Every 5 years with rated load at rated car speed in the down direction

Governors are critical components in elevator systems, as they regulate the speed of the elevator and ensure safe operation. The correct testing frequency and procedure are crucial to maintain their functionality and safety standards. Testing governors every 5 years with rated load at the rated car speed in the downward direction is important because it allows for a comprehensive assessment under conditions that closely simulate actual operational scenarios. When tested in this manner, the governor's performance can be closely monitored to ensure it effectively engages when the elevator exceeds its maximum speed. This type of testing evaluates the governor's response, reliability, and mechanical integrity, ensuring it can handle real-world stresses. Testing with the rated load is essential since it represents the maximum capacity the governor will need to manage. Evaluating the governor in the downward direction is particularly critical because this condition often results in higher velocity scenarios than the upward movement, thus rigorously testing its capabilities. This protocol is established by safety codes and practices to ensure compliance and the ongoing safe operation of elevator systems. Regular and thorough testing is necessary to avoid potential hazards associated with governor failure, which could compromise the safety of passengers.
