Elevator Mechanic Licensure Exam Practice Test Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of an elevator governor?
• To provide ride comfort
• To regulate door operation
• To control overspeed conditions
• To align the car at landings

The governor detects overspeed and activates the safety mechanism to stop the car.

2. The minimum required pit depth is determined primarily by:

• Machine room size
• Hoistway ventilation
• Buffer stroke and clearances 1 / 4

• Door opening width

Pit depth ensures adequate space for buffer compression and maintenance clearances.

3. A traction elevator’s rope traction depends most on:

• Car weight
• Groove design and rope tension
• Governor speed
• Door weight

Groove shape and rope tension create the friction needed for traction.

4. The function of the safeties is to:

• Level the car
• Stop the car in overspeed downward travel
• Control door timing
• Monitor rope wear

Safeties engage via the governor to stop downward overspeed.

• Which electrical device prevents the elevator from running with open

doors?

• Selector
• Load weigher
• Door interlock
• Resistor

Interlocks ensure hoistway doors are closed and locked before movement. 2 / 4

6. Counterweight overbalancing is used to:

• Reduce machine noise
• Increase governor speed
• Reduce motor power requirements
• Increase maximum load

Counterbalancing reduces the work required by the motor.

7. The plunger of a hydraulic elevator is typically made of:

A. PVC

• Aluminum
• Steel
• Fiberglass

Steel supports high pressure and vertical load.

• What fluid is used in hydraulic elevator systems?
• Water
• Hydraulic oil
• Gasoline
• Brake fluid

Hydraulic oil provides pressure transfer and lubrication.

9. The main cause of rope slippage on a traction sheave is:

• High humidity
• Excess counterweight
• Improper rope tension 3 / 4

• Door imbalance

Uneven or incorrect tension reduces friction for traction.

10. A hoistway must be constructed to provide:

• Side door openings
• Fire-rated enclosure
• Exterior lighting
• Machine room space

Codes require fire-rated hoistway construction.

11. Hydraulic elevators should have a rupture valve to:

• Increase pressure
• Prevent uncontrolled descent
• Regulate oil temperature
• Reduce noise

A rupture valve stops the car if hydraulic pressure suddenly drops.

12. The car top inspection station allows:

• Car leveling
• Slow-speed operation for maintenance
• Increased capacity
• Remote rescue operations

Inspection mode allows manual, slow car control.

• The term “top of car clearance” refers to:
• / 4
