EIAT - Elevator Industry Aptitude Tool Recognition and Use Questions and Answers — Questions and Answers
Question 1: A technician needs to verify that a newly installed guide rail is perfectly vertical. Which of the following tools is the most appropriate for this task?
- A tape measure
- A spirit level (Correct answer)
- A framing square
- A caliper
Correct answer: A spirit level
A spirit level is specifically designed to indicate whether a surface is perfectly horizontal (level) or vertical (plumb). While a framing square can check for 90-degree angles, it doesn't verify verticality over a distance as effectively as a level.
Question 2: When terminating electrical wires in a control panel, which tool is essential for ensuring a secure and reliable connection by attaching a terminal to the end of a wire?
- Wire strippers
- Lineman's pliers
- Crimpers (Correct answer)
- Diagonal cutters
Correct answer: Crimpers
Crimpers are specialized tools used to deform a crimp terminal around a wire, creating a solid and secure electrical connection. While wire strippers prepare the wire and pliers can manipulate it, only crimpers are designed for this specific purpose of attachment.
Question 3: A technician is working in a dimly lit elevator pit and needs to have both hands free to make an adjustment. Which of the following would be the most practical tool to use for illumination?
- A handheld flashlight
- A portable work light
- A headlamp (Correct answer)
- A smartphone's built-in light
Correct answer: A headlamp
A headlamp is the most practical choice as it is worn on the head, directing light wherever the technician looks while keeping both hands completely free to work safely and efficiently.
Question 4: Which of the following tools combines multiple functions, typically including Phillips and flathead screwdrivers, as well as nut drivers, into a single handle?
- A multi-tool
- A 6-in-1 or 11-in-1 screwdriver (Correct answer)
- A socket wrench set
- A terminal screwdriver
Correct answer: A 6-in-1 or 11-in-1 screwdriver
A 6-in-1 or 11-in-1 screwdriver is a specific type of hand tool designed for efficiency by housing multiple interchangeable bits (like Phillips and flathead) and nut driver sizes within its shaft and handle.
Question 5: A technician needs to measure the outside diameter of a hoist rope to check for wear. To get the most precise measurement, which tool should be used?
- A folding ruler
- A tape measure
- Calipers (Correct answer)
- A straight edge
Correct answer: Calipers
Calipers are precision instruments used to measure internal and external distances with a high degree of accuracy, making them the ideal tool for checking the exact diameter of a rope or cable.
Question 6: In a situation requiring the removal of a worn bolt with a rounded head, which tool would provide the best grip to turn it?
- An open-end wrench
- A Phillips head screwdriver
- Locking pliers
- A socket wrench (Correct answer)
Correct answer: A socket wrench
A socket wrench surrounds the bolt head on multiple sides, providing a much better grip than an open-end wrench, especially if the head is damaged. The design distributes turning force evenly, reducing the chance of further stripping the bolt head.
