NEIEP Mechanics Practice Exam

How is the location of the governor tension sheave determined?

1. By the manufacturer's instructions

2. By the length of the ropes

3. From the final layout drawing

4. By the safety regulations

The correct answer is: From the final layout drawing

The correct choice reflects that the location of the governor tension sheave is determined based on the final layout drawing. This drawing is an essential reference as it includes the specific design and arrangement of the hoisting system. It details how components, including the governor tension sheave, must be placed to ensure proper function and effective operation of the elevator system. Using the final layout drawing helps ensure that the governor tension sheave is positioned correctly in relation to other components, which is crucial for maintaining the appropriate tension in the ropes and for the overall safety and performance of the elevator system. This structured approach prevents discrepancies during installation and guarantees that all components work together efficiently. While manufacturer instructions and safety regulations do offer valuable guidance, they often rely on the specifics outlined in the layout drawing to dictate precise installation points. The length of the ropes also plays a role, but it is typically the final layout that governs the spatial relationships of all elements within the system.
