Elevator Mechanic Practice Exam

How is a class 1 yearly buffer test performed?

1. Car at bottom landing and on inspection, jump out direction and final limits. With pit clear, run down to compress buffers, buffers should fully extend within 90 seconds

2. Car at top landing and on inspection, engage all safety mechanisms

3. Operational test at every stop with loaded car

4. Visual inspection of all components

The correct answer is: Car at bottom landing and on inspection, jump out direction and final limits. With pit clear, run down to compress buffers, buffers should fully extend within 90 seconds

The process for a Class 1 yearly buffer test is indeed correctly described by the choice selected. In this test, starting with the car at the bottom landing allows for a proper assessment of the buffer's function in a controlled environment. By jumping out of the direction and final limits while ensuring that the pit is clear, the test can effectively simulate the worst-case scenario where the elevator would need to compress the buffers fully. The requirement for the buffers to fully extend within 90 seconds ensures that the safety and operational standards are being met, verifying that the buffers work as intended to absorb excessive energy during a potential impact. This testing approach is crucial for maintaining elevator safety standards and confirming that the buffer system is functioning correctly. Other options do not address the specific requirements and procedures for the Class 1 yearly buffer test as comprehensively as the selected answer. While they may touch upon operational safety or components, they lack the detailed operational methodology necessary for conducting the buffer test itself.
