NEIEP Mechanics Practice Exam

Why must the plunger be securely attached to the car sling?

1. To facilitate maintenance

2. To ensure proper alignment

3. So the car cannot hang up and cause it to crash

4. To allow for easier testing

The correct answer is: So the car cannot hang up and cause it to crash

The plunger must be securely attached to the car sling to ensure that the car operates safely and effectively within its designated track. A secure attachment helps prevent the car from becoming dislodged or hanging up, which could lead to a loss of control and ultimately a crash. This connection is crucial for maintaining the integrity of the elevator system during operation, as any failure in this area could result in catastrophic consequences for both the car and its passengers. While other considerations like maintenance, alignment, and testing are important in their own right, they do not directly address the immediate safety risks involved in the car's movement. Safety is always the priority in any mechanical system, especially one that transports people, making the secure attachment of the plunger to the car sling fundamental for safe operation.
