1. Which type of contractor license is required in Nevada to perform
elevator and conveyance installation, alteration, and repair work?
A. C-2 Electrical Contractor
B. C-7 Elevation & Conveyance Contractor
C. C-21 Refrigeration Contractor
D. B General Building Contractor
Rationale: The Nevada C-7 Elevation & Conveyance Contractor
classification authorizes contractors to install, alter, maintain, repair,
and modernize elevators, escalators, moving walks, wheelchair lifts,
dumbwaiters, and similar conveyance systems. Contractors must work
within the scope of their license.
, 2. Which safety principle should always be followed before servicing
elevator equipment?
A. Increase motor speed
B. Disable emergency communication
C. Apply lockout/tagout (LOTO) procedures
D. Remove all warning signs
Rationale: Lockout/tagout procedures isolate hazardous energy
sources before maintenance begins. Proper LOTO prevents unexpected
startup and protects workers from electrical, hydraulic, and
mechanical hazards.
3. What is the primary purpose of an elevator governor?
A. Increase travel speed
B. Reduce energy consumption
C. Detect overspeed conditions and activate safety devices
D. Control door operation
Rationale: The governor continuously monitors elevator speed. If
excessive speed is detected, it activates the safety gear, helping stop
the elevator safely and preventing uncontrolled movement.
, 4. Which component supports and moves the elevator car?
A. Counterweight frame
B. Guide rails
C. Hoist ropes
D. Door operator
Rationale: Hoist ropes connect the elevator car to the counterweight
and transmit lifting force from the drive machine. Their condition is
critical to safe operation.
5. Why are guide rails installed inside the hoistway?
A. To increase elevator speed
B. To cool the motor
C. To guide the car and counterweight safely
D. To store electrical cables
Rationale: Guide rails maintain the alignment of the elevator car and
counterweight throughout travel, reducing sway and ensuring
smooth, safe movement.
, 6. What is the primary function of the elevator counterweight?
A. Increase passenger capacity
B. Reduce door noise
C. Balance the weight of the car and improve efficiency
D. Operate emergency lighting
Rationale: The counterweight offsets much of the elevator car's
weight, reducing motor workload, improving efficiency, and lowering
energy consumption.
7. Before entering an elevator pit, a technician should first:
A. Test the alarm bell
B. Remove guide rails
C. Ensure the elevator is secured and follow confined-space and safety
procedures
D. Disconnect the governor
Rationale: Elevator pits present fall, electrical, and mechanical
hazards. Proper securing of equipment and compliance with safety
procedures protect technicians during maintenance.
8. Which electrical instrument measures voltage?
