Top 10 Questions for Elevator Mechanic Interview

1. Describe the process of leveling an elevator car.

The process of leveling an elevator car involves adjusting the car’s position so that it is level with the floor at each landing. This is done by using a level sensor to measure the car’s position and then adjusting the car’s position accordingly. The level sensor is a device that uses a bubble or other mechanism to measure the car’s angle of inclination. The car’s position is adjusted by using a hydraulic or electric motor to move the car up or down.

2. How do you troubleshoot a malfunctioning elevator door?

Mechanical problems

• Check the door tracks for obstructions or damage.
• Check the door rollers and bearings for wear or damage.
• Check the door springs for proper tension.

Electrical problems

• Check the door motor for proper operation.
• Check the door limit switches for proper operation.
• Check the door safety sensors for proper operation.

Other problems

• Check the door lock for proper operation.
• Check the door weatherstripping for damage.

3. What are the safety precautions that you should take when working on an elevator?

• Lock out and tag out the elevator before working on it.
• Wear appropriate safety gear, such as gloves, safety glasses, and a hard hat.
• Be aware of your surroundings and the potential hazards involved in working on an elevator.
• Follow all safety procedures and guidelines.
• Never work on an elevator alone.

4. How do you calculate the load capacity of an elevator?

The load capacity of an elevator is calculated by multiplying the number of passengers by the average weight of a passenger. The average weight of a passenger is typically assumed to be 150 pounds. For example, an elevator with a capacity of 10 passengers would have a load capacity of 1,500 pounds.

5. What are the different types of elevator drives?
