concern?
A. Increased ride comfort
B. Reduced motor efficiency
C. Minor leveling inaccuracies
D. Potential uncontrolled car movement
The elevator brake is a critical safety component designed to stop and hold
the car when power is removed. Failure to do so can result in unintended
movement and serious hazards to passengers and maintenance personnel.
2. Which document is generally most important for verifying that a newly
installed elevator conforms to approved design requirements?
,A. Cleaning schedule

compliance.
3. In a hydraulic elevator system, the primary function of the cylinder and
piston assembly is to:

A. Ignore the condition if the elevator is operating normally
B. Allow operation until the next annual inspection
C. Identify the condition as a safety deficiency requiring correction
D. Disconnect all hall call buttons
Top-of-car inspection controls are essential for safe maintenance and
inspection activities and must function properly to ensure worker safety.
5. The governor in a traction elevator is primarily intended to:
A. Increase travel speed

, Door interlocks ensure that the elevator cannot operate unless landing
doors are closed and locked, protecting passengers from exposure to the
hoistway.
9. During a periodic inspection, an elevator car is found to stop
significantly above and below floor level. This condition is commonly
referred to as:
A. Counterweight drift
B. Brake glazing
C. Rope stretch failure
