Elevators Trivia Questions
1. The largest elevator company at the end of the 20th century was the Otis Elevator Company, named after the founder, Elisha Otis. What was the major contribution that Elisha made to the design of elevators?

From Quiz Down With Elevators!

Answer: He invented the safety elevator

Elisha Otis invented the first safety elevator. He attached the hoist rope for the elevator to a spring at the top of the elevator and the spring was attached to a a pair of ratchet bars on the sides of the elevator. As long as the spring had tension on it, the ratchet bars were not engaged. But if the rope broke, the tension on the spring was released, allowing the ratchet bars to engage and stop the elevator. During the 1854 New York World's Fair, he had himself hoisted in an open elevator up a couple of stories, and had an axe man cut the hoist rope, showing that his invention would work.

2. What is the function of a counterweight in a cable-driven elevator system?

From Quiz Down With Elevators!

Answer: To make the system more efficient

To reduce the load on the motor that pulls the elevator car up, there is a counterweight which is equal to the weight of the car and a half-load of passengers. This makes the system more efficient and reduces energy consumption.

3. If an elevator is said to be roped 1:1, how many sheaves are placed on top of the car?

From Quiz Elevators!

Answer: 0

1:1 roping involves hitching directly to the car and counterweight.

4. In an elevator, what does COP stand for?

From Quiz Elevators!

Answer: Car Operating Panel

It's the panel inside the cabin, housing call buttons, key switches and flex terminations.

5. What are glass elevators made of?

From Quiz Down With Elevators!

Answer: Clear polycarbonate

Clear polycarbonate is used in "glass" elevators because it is much stronger and many times more durable than real glass. It is also much lighter than real glass. It is the same stuff that is used for making eyeglasses. Clear acrylic plastic does not have the strength that polycarbonate does. Transparent aluminum is now a fact, but it's very expensive to make, $10 to $15 per square inch at the time of writing this quiz.

6. In which southern hemisphere country could you find an elevator that drops 2283 meters in a single descent?

From Quiz Down With Elevators!

Answer: South Africa

The AngloGold Ashanti's Mponeng Gold Mine in South Africa drops the incoming miners 2,283 meters (7,490 feet) in a single descent at speeds up to 40 miles per hour. When they get to the bottom,a second elevator takes them another 3,597 feet to the bottom of the shaft. The elevator car is three levels and carries 120 workers at a time. In 2019, this was the tallest elevator in the world, and it travels more than four times further than elevators in the world's tallest building at that time.

7. What is the mechanism called that detects if the elevator is going too fast?

From Quiz Elevators!
