Top 10 Questions for Elevator Erector Interview

1. What are the different types of elevators, and what are their advantages and disadvantages?

There are many different types of elevators, each with its advantages and disadvantages. Some of the most common types include:

• Hydraulic elevators: These elevators use a hydraulic cylinder to raise and lower the car. They are relatively inexpensive to install and maintain, but they are not as fast or efficient as other types of elevators.
• Traction elevators: These elevators use a traction motor to drive the car up and down the shaft. They are more expensive to install and maintain than hydraulic elevators, but they are faster and more efficient.
• Gearless elevators: These elevators use a permanent magnet motor to drive the car up and down the shaft. They are the most expensive type of elevator to install and maintain, but they are also the most efficient and reliable.
• Machine room-less elevators: These elevators do not require a separate machine room. The motor and other components are located in the elevator shaft. This makes them ideal for buildings with limited space.

2. What are the safety precautions that must be taken when working on elevators?

Personal Protective Equipment (PPE)

• Hard hat
• Safety glasses
• Gloves
• Safety harness

General Safety Precautions

• Never work on an elevator without first isolating the power.
• Always use a ladder or scaffold when working on an elevator.
• Never step onto an elevator car that is in motion.
• Never reach into an elevator shaft while the elevator is in motion.
• Always be aware of your surroundings and the location of other workers.

3. What are the different types of elevator components, and what are their functions?

The main components of an elevator include:

• Car: The car is the part of the elevator that carries passengers and freight.
• Shaft: The shaft is the vertical opening in which the car travels.
• Machine room: The machine room is the space where the elevator’s motor, controller, and other components are located.
• Controller: The controller is the brains of the elevator. It receives signals from the buttons and sensors, and it sends signals to the motor to control the movement of the car.
• Motor: The motor is the power source for the elevator. It drives the car up and down the shaft.
• Brakes: The brakes stop the car and hold it in place when it is not in motion.
• Doors: The doors allow passengers to enter and exit the car.

4. What are the different types of elevator control systems, and what are their advantages and disadvantages?

The two main types of elevator control systems are:

• Relay logic control systems: These systems use relays to control the movement of the elevator. They are relatively inexpensive and easy to maintain, but they are not as flexible or efficient as microprocessor control systems.
• Microprocessor control systems: These systems use microprocessors to control the movement of the elevator. They are more expensive and complex than relay logic control systems, but they are more flexible and efficient.

5. What are the different types of elevator maintenance tasks, and how often should they be performed?

The different types of elevator maintenance tasks include:

• Daily maintenance: This includes tasks such as checking the oil level, greasing the bearings, and inspecting the brakes.
• Weekly maintenance: This includes tasks such as cleaning the car and the shaft, and checking the operation of the doors.
• Monthly maintenance: This includes tasks such as testing the emergency brake, and inspecting the hoistway.
• Quarterly maintenance: This includes tasks such as lubricating the motor and the gearbox, and checking the operation of the controller.
• Annual maintenance: This includes tasks such as inspecting the car and the shaft, and testing the safety devices.

6. What are the most common problems that can occur with elevators, and how can they be fixed?

The most common problems that can occur with elevators include:

• Car stuck between floors: This can be caused by a number of factors, such as a power outage, a mechanical failure, or a problem with the control system.
• Door not opening: This can be caused by a number of factors, such as a problem with the door operator, a problem with the door sensor, or a problem with the control system.
• Elevator not moving: This can be caused by a number of factors, such as a power outage, a mechanical failure, or a problem with the control system.

7. What are the latest trends in elevator technology?

The latest trends in elevator technology include:

• The use of artificial intelligence (AI) to improve elevator performance and safety.
• The development of new elevator designs that are more energy-efficient and environmentally friendly.
• The use of new materials and technologies to make elevators more durable and reliable.

8. What are the different types of elevator inspections, and how often should they be performed?

The different types of elevator inspections include:

• Quarterly inspections: These inspections are performed by a qualified elevator inspector and include a visual inspection of the elevator, as well as a test of the elevator’s safety devices.
• Annual inspections: These inspections are more comprehensive than quarterly inspections and include a more detailed inspection of the elevator’s components, as well as a test of the elevator’s performance.
• 5-year inspections: These inspections are the most comprehensive type of elevator inspection and include a complete disassembly and inspection of the elevator.

9. What are the different types of elevator certifications, and how can they be obtained?

There are a number of different elevator certifications available, including:

• Elevator mechanic certification: This certification is required for individuals who install and maintain elevators.
• Elevator inspector certification: This certification is required for individuals who inspect elevators.
• Elevator designer certification: This certification is required for individuals who design elevators.

10. What are the different types of elevator codes and standards, and how do they affect the design and installation of elevators?

There are a number of different elevator codes and standards that affect the design and installation of elevators, including:

• The ASME A17.1 Safety Code for Elevators and Escalators
• The International Building Code (IBC)
• The National Fire Protection Association (NFPA) 70: National Electrical Code (NEC)
